4. Costs & Billing

4a. Cost Control

How AdWords Controls Costs

Objective: Learn how AdWords helps keep your costs down with the AdWords Discounter and smart pricing.

AdWords Discounter and Actual CPC/CPM 

With Google AdWords, you set a cost-per-click (CPC) bid or cost-per-1000-impressions (CPM) bid. However, the AdWords Discounter works so you usually end up paying less than this amount.

Here's how it works: After we determine your ad rank, the AdWords Discounter calculates your actual CPC or CPM. This is the actual amount you pay to maintain your ad's position above the next lower ad. Your actual CPC or CPM is never more than the maximum CPC or CPM bid you specify.

Smart Pricing 

Content clicks may be priced differently than search clicks. Using smart pricing, AdWords automatically adjusts the cost of clicks for ads that appear on content network pages with CPC pricing. If our data shows that a click from a content page is less likely to turn into actionable business results — such as online sales, registrations, phone calls, or newsletter signups — we actually reduce the price you pay for that click.

For example, let's say that you advertise digital cameras. Your ad appears on two different pages — one that reviews digital cameras and another that offers photography tips. Since users are more likely to click on your ad for digital camera reviews (and thus convert into more sales), Google doesn't discount these ads. However, Google determines that clicks from the photography tips page convert into sales less frequently and therefore charges you less per click.

Smart pricing adjustments are automatically reflected in the Avg. CPC column on your Campaign Summary page. Smart pricing is related to clicks, so smart pricing doesn't apply to cost-per-thousand impressions (CPM) campaigns.

 
 
How You Can Control Costs

Objective: Learn how you can control your AdWords advertising costs — primarily through your daily budget and bids. Understand some advanced pricing options, including preferred cost bidding and content bids.

Setting the Right Budget 

The daily budget is the primary way to control your overall costs. It determines the most you're willing to spend per day per campaign. Since you set a daily budget for each campaign in your account, you can add up all of your daily budgets to get an idea of how much you could spend per day for your entire account.

The daily budget determines how often your ads show throughout the day. You can set your daily budget to be as high or as little as you want. You set your daily budget via your Edit Campaign Settings page:

  1. Sign in to your account at https://adwords.google.com.
  2. Check the campaign you want to edit.
  3. Click Edit Settings.
  4. Set a daily budget under the Budget Options section.
When choosing a daily budget, keep the following in mind:
  • Your daily budget must always exceed your CPC or CPM bid. If it doesn't, your ad won't show.

  • You can view the recommended daily budget — based on the keywords or sites you choose, bid amount, and other factors — by clicking the View Recommended Budget link below the Budget field.

  • If the recommended daily budget is more than you can afford, optimize your keywords, ads, or targeting options. To learn more, visit the Preparing to Optimize lesson.

  • You can choose between two ad delivery methods when setting a daily budget:
    (1) Standard (default setting): Your ad appears intermittently throughout the day if we find that your ad receives more charges than your daily budget allows. This means that your ad will be shown less frequently but spread out evenly throughout the course of the day — rather than shown only in the morning.

    (2) Accelerated: Your ad appears as often as possible until your budget is reached. If your budget is low, this means that your ads may stop showing early on in the day, as soon as your budget has been exhausted.
  • We may "overdeliver" your ad up to 20% more than your specified daily budget on a given day to provide your ad extra exposure on heavy-traffic days and to make up for days when traffic is low. If we exceed your monthly budget (daily budget X 30 days), we'll issue overdelivery credits to your bill. See the Billing lesson for more details.

Setting the Right Bids 

Your maximum CPC or CPM bid represents the highest amount that you're willing to pay per click or thousand impressions, respectively, on your ad. You set your bid for ad groups or for individual keywords or placements. (See the Ad Group Details page for more details). If you don't specify a maximum CPC or CPM bid for a given keyword or placement, the ad group maximum CPC or CPM bid will automatically apply to all keywords or placements.

When setting your CPC or CPM bid, consider the following:

  • Your Quality Score. This is the single most important factor we use in determining the price you pay per click ads targeted by keywords. Remember that your keyword's Quality Score sets the minimum amount you must bid in order for your ad to show. Therefore, you can decrease the minimum bid and the overall costs of your ads by increasing your Quality Score. To learn more, visit Preparing to Optimize lesson.

  • The value of a click. How much is it worth for someone to visit your website? How likely is it that a click will turn into a conversion (sale, signup, etc.)? If high, then you might want to set a high bid. If low, lower the bid. You can get conversion statistics by setting up conversion tracking or by using Google Analytics.

  • Your daily budget. We've said it before, and we'll say it again: Be sure that your daily budget is higher than your CPC or CPM bid. Otherwise, your ad won't show.

Preferred Cost Bidding 

Preferred cost bidding is an advanced bidding option that lets you specify an average amount you want to pay, rather than the maximum amount you're willing to pay per click or per thousand impressions.

In campaigns targeting the search network, you can select the average price you'd like to pay per click (a preferred CPC bid). In campaigns targeting the content network, you can set an average price per thousand impressions (a preferred CPM bid) or per click. (CPC pricing is not available for campaigns that target the search network.) The AdWords system then automatically works to hit this target price.

For example, if your analysis shows that a click on an ad is worth US$0.75 to your business, you can set a preferred CPC bid of US$0.75. The AdWords system will then adjust your bid on individual ad impressions to bring your actual average CPC as close to US$0.75 as possible. Your ad may be placed in a range of positions as the system works to give you your preferred cost.

If preferred CPC or CPM bidding fits your advertising goals, you can select this option in the Advanced Options section of the Edit Campaign Settings page of your campaign.

Content Bids 

The content bids feature lets you set different bids for clicks on the content network and for clicks on the search network. It's especially useful if you find that you get a higher return on clicks from one network than the other.

For example, if you find that clicks on search pages return more sales than you get with clicks on content pages, you might want to lower your content bids.

To enable content bids for a keyword-targeted campaign, find the Networks and bidding section of your Edit Campaign Settings page. Make sure 'The content network' is selected, then also select 'Set a separate bid for content network impressions.' After you save this change, you'll be invited to enter a content bid or bids.

Once you've enabled content bids, you can make separate bids for content pages in any of the ad groups within that campaign. Here's how:

  1. Sign in to your AdWords account at https://adwords.google.com.
  2. Click the name of the campaign you want to adjust.
  3. Put a check in the box next to any ad groups for which you want to set separate content bids.
  4. Click the button marked Edit Bids.
  5. Enter your new prices for each ad group in the column marked Content. (Default is your bid for search sites, and Placements is an optional separate default bid for when your ad appears on placements from this ad group.)
  6. If needed, click the small button marked with a downward arrow to copy the same bids across all ad groups.
  7. Click Save Changes.
Continue to monitor your campaign performance, and make adjustments as needed. To learn more about assessing performance, visit the Quality and Performance Basics lesson.

 
 

4b. Billing Cycle

Basic Billing Process

Objective: Learn how you are billed for advertising costs, and about different payment options that are available.

How Charges Accrue 

With cost-per-click (CPC) advertising, you accrue advertising costs only when users click on your ad; you are charged for each click based on the CPC bid that you assign to each ad group or keyword. With cost-per-impression (CPM) advertising, you are charged for each time your ad is displayed, based on the CPM bid you set for each ad group, keyword or placement.

At the end of your billing period, you will be charged for all costs accrued during that cycle. The AdWords billing period is defined by Google and is not the billing period of your credit card.

Payment Options 

Available payment options depend on your billing address and chosen currency. In this topic, we will cover postpay payment by credit card, which is the most widely available method of payment.

Google currently accepts Visa, MasterCard, American Express, JCB, and debit cards with a MasterCard or Visa logo. Please refer to the Payments Outside of the US lesson to learn about direct debit, bank transfer, and Switch/Solo payment methods available in countries where credit cards are not widely used.

Depending on the payment methods offered in your location, you may also have the option to pay for your advertising prior to receiving clicks (prepay) or after receiving clicks (postpay).

With our prepay option, we will deduct charges from your pre-paid balance each time a Google user clicks on your ads. Your ads run almost immediately after payment is received.

Our postpay option allows you to pay after users click on your ads and you accrue charges. Your ads run almost immediately after submitting your credit card and billing information.

Determine the payment options available for your billing address and currency.

In addition to these payment options, a select group of advertisers also has the option to receive invoices once a month. You can learn more details about invoicing by reviewing the Invoicing lesson.

The AdWords Billing Cycle 

Your credit card is charged based on your AdWords billing cycle. When you create and activate your account with a credit card, debit card, or direct debit, Google starts running your ads almost immediately. We then charge you every 30 days unless your advertising costs reach a certain threshold within your 30-day billing cycle.

We won't charge you before 30 days unless you earn US$50 worth of clicks or impressions, depending on whether you're running a CPC or CPM campaign. The first time your account reaches US$50 within 30 days, we'll charge you. Then, we'll let you accrue US$200 worth of clicks before charging you within the subsequent 30 days.

If you reach your US$200 limit within 30 days, Google will bill you and raise your billing threshold to US$350. Once you reach the US$350 threshold, you'll be billed again, and your threshold will be raised to US$500, the maximum allowed. Remember that the amount billed may be in excess of the threshold since ads will continue to run and generate charges between the time the billing cycle is triggered and the time the charge is completed.

The activation fee, along with any other advertising costs accrued, is charged to your credit card at the end of your first billing period.

 
 
Billing Details & Issue Resolution

Learn about the billing summary and payment details for an account, including the application of overdelivery credits, how to resolve declined credit card charges, and how to calculate pending charges. Also, become familiar with Google's credit card security practices.

Billing Summary and Payment Details Pages 

On the Billing Summary page you'll see your billing history and invoices for your account. You can access more detailed information about each invoice by clicking the invoice number link.

Your Billing Summary page will appear differently if you're billed on a postpay or prepay basis.

If you are billed on a prepay basis, your page will display the following information.


Figure: AdWords Billing Summary page for prepay advertisers.

1. Date: The date of payment and invoice activity for your account.

2. Activity: Account adjustments, charges, or declined payments that occurred for the reported month, and unique invoices for each payment toward your account.

3. Charge: Your total advertising costs accrued for any month. This column will also include adjustments and credits made, including promotional credits, credits for invalid charges toward your account, and courtesy credits applied by AdWords client services specialists.

4. Payment: Individual payment amounts for the current month. For each payment, you can click the related invoice link to view details about the payment method and amount.

5. Balance Remaining: Balance remaining in your account. As you make payments and accrue costs, your Balance Remaining column will display the amount of prepaid funds left in your account.

6. Funds Remaining: Current balance remaining in your account. Though similar to the Balance Remaining, this amount is based on slightly more updated usage statistics than the Balance Remaining and reflects your most up-to-date costs accrued, at any time.

If you're billed on a postpay basis, your Billing Summary page will show the following information:


Figure: AdWords Billing Summary page for postpay advertisers.

1. Date: The date of payment and invoice activity for your account.

2. Activity: Account adjustments, charges, or declined payments that occurred for the reported month, and unique invoices for each payment toward your account.

3. Invoiced Amount: Costs per campaign are itemized by the date billed and relevant invoice number. Adjustments will be included within the invoiced amount, and may reflect promotional credits, credits for invalid charges toward your account, and courtesy credits applied by AdWords client services specialists.

4. Payment: Individual payment amounts for the current month.

5. Balance Due: Invoiced balance. For postpay accounts, where payments are made promptly following each invoice, the balance column will typically be zero. This is because the Balance Due column does not reflect recent clicks or impressions for which you have not yet been invoiced.

6. Outstanding Balance: Overall balance. This amount reflects your most up-to-date costs accrued, including clicks or impressions for which you have not yet been invoiced as well as any outstanding billed balance.

Invoice Details 

If you would like more details regarding a specific payment, click the invoice number that you wish to review. This will take you to the Invoice Details page.

Click Printable invoice to print an invoice for your records.

payment details
Figure: AdWords Invoice Details page.

1.Invoice Details: Invoice/payment date and time, applicable taxes, and your invoice number. You can also print your invoice, which will include your payment terms (immediate charge or credit line), and all line items associated with your payment.

2.Account Adjustments and Fees: Applicable fees (account activation or re-activation) and billing adjustments that may reflect promotional credits, credits for invalid charges toward your account, and courtesy credits applied by AdWords client services specialists.

3.Advertising Charges by Campaign:

  • Campaign: Relevant campaign for which activity was recorded.
  • Date Range: Corresponding dates for activity accrued per campaign.
  • Billable Activity: Explanation of charges (clicks, impressions, or overdelivery credit).
  • Number of clicks or impressions: The number of clicks or impressions accrued.
  • Daily Budget: The daily budget for the relevant campaign for the delivery period shown.
  • Amount: Charges accrued during the delivery period shown. This amount may also include overdelivery adjustments.
  • Total: Subtotals appear per campaign in the right-hand column; the final line represents total advertising charges for the invoice.

Payment Received Link 

If you return to the Billing Summary page, you'll see that each invoice has a Payment received link. Click on this link to view the Payment Details page.

Payment Details 

The Payment Details page lists the date and time a payment was received, the form of payment, and the amount credited.

You can print a receipt for your records from the Payment Details page by clicking the Printable receipt link.

Overdelivery Credits 

As traffic is never constant from day to day, it is possible that your cost-per-click campaign may accrue charges above or below your set limit. To ensure that your CPC campaigns reach their potential, Google may allow up to 20% more clicks in one day than your daily budget specifies. However, we'll never charge you more than your daily budget multiplied by the number of days in that delivery period.

For example, if you budget US$10 per day in a 30-day month, you may receive more than US$10 in clicks on a given day, but the maximum you would pay is US$300 for that month. If Google overdelivers your ads resulting in more clicks than your budget allows, you will receive a credit to your account. Credits for clicks in excess of your daily budget are listed on your invoice as: 'Overdelivery credit.'

Example Scenario

Advertiser's Daily Budget = US10

Day 1 Spend: US$8
Day 2 Spend: US$10
Day 3 Spend: US$12
Day 4 Spend: US$14

In the above example, this advertiser received US$12 worth of clicks on Day 3. That's US$2, or 20%, more than the daily budget.

On Day 1, the advertiser only received $8 worth of clicks, so Google will apply the US$2 worth of overdelivery charges to Day 1. By applying these charges to Day 1, charges on Day 3 meet the advertiser's daily budget.

On Day 4, the advertiser receives US$14 in clicks. Since Google has allowed his campaign to accrue US$14 in clicks, or 40% above the daily budget, Google will return 20%, or US$2, as an overdelivery credit. In addition, the remaining 20%, or US$2, will also be applied as an overdelivery credit because the advertiser reached his daily budget each day.

Credit Card Declines 

If Google is unable to charge a credit card, advertising is suspended for that account. AdWords notifies the advertiser via email that his or her credit card has been declined.

You can view detailed information regarding any declined payments on the Payment Declined Details page. Here you'll see itemized payment declination details by invoice, including the date and amount of the attempted charge, and the reason our billing system was unable to process your payment.

There are several common reasons why credit cards are declined. If your payment is declined, consider the following:

  • Have you entered the correct credit card number?
  • Have you entered the correct expiration date? Has that date passed?
  • Have you entered the correct billing address and phone number? If the address and phone number listed in your AdWords account do not match those associated with your credit card, we may be unable to process your charges.
  • Have you exceeded your credit limit? Your credit card must have enough available credit to cover your monthly advertising budget. If your card does not have enough credit, you'll need to decrease your daily budget, or enter a new credit card with a higher credit limit. You may need to contact the issuing bank to determine the credit limits on your credit card.
If you still cannot successfully submit your credit card information after reviewing the information above, contact the card-issuing bank for details about why they have declined the particular transaction.

In order to process the declined charge and reactivate your account, you'll need to update your billing information. Please note that this is the only way to process a failed payment. If you plan to use the same credit card, you can simply click the 'Retry card' button to trigger us to try your card again. Once we process your payment successfully, your ads will begin running again.

If you're not already using a backup credit card, you may wish to enter one to help ensure continuous ad delivery in the future. When you provide a backup credit card, we'll try to charge it if your primary card is declined in the future. You can enter a backup credit card by visiting your Billing Preferences page and adding a card in the Backup Payment Details section.

Pending Charges 

Your pending charges are determined by the number of clicks your ads have received since the last time you were billed. (If you're running a CPM campaign, the charges are determined by the number of impressions you've received.) All pending charges can be viewed on the Billing Summary page in your account. The outstanding balance on this page reflects the cost of accrued charges since you were last billed.

Your outstanding balance provides an estimate for upcoming charges for your campaigns. Please note that this amount does not necessarily reflect a delinquent amount, or a final balance. The outstanding balance is updated throughout the day, and includes deductions for any overdelivery credits that may apply. However, this balance may still be more than what you are actually charged for that time period, as additional overdelivery credits may be applied prior to billing your account. All credits and past charges posted to your credit card are also available under the My Account tab.

If you pause or delete your campaigns, it is important to note that any pending charges will be charged to your credit card at the end of your billing period. Because your AdWords account runs on a 30-day billing cycle, you may be billed for your campaigns up to one month after pausing or deleting them.

For example, an advertiser is billed for his account on June 4, and then pauses his campaigns on June 18. He would then be billed on July 4 for any charges accrued between June 4 and June 18.

Credit Card Security 

Our highest priority is to ensure the security and confidentiality of your personal information.

Google uses industry-standard SSL (secure socket layer) technology to protect every interaction you have with the AdWords system. This protects your credit card and other personal information. Once we receive your information, it is encrypted and stored behind a firewall.

When payment information is submitted online, Google works with third-parties to verify and process your information. Your personal information is encrypted and neither Google nor our payment partners share or sell your personal information. Your information will only be used for the purpose for which it was provided. For more details, please see our Privacy Policy.

 
 

4c. Payments outside the U.S.

Payment Options

Learn about various payment options that are available to AdWords advertisers, and how to select the option that's best suited for you.

Prepay & Postpay 

Google's payment options can be divided into two categories: prepay and postpay.

Our prepay option allows you to pay for advertising before you accrue charges, and postpay allows you to pay for advertising after you accrue charges.

To find out what payment options are available to you, visit https://adwords.google.com/select/AfpoFinder.

Postpay: Credit/Debit cards and Direct debit

Postpay means you pay Google only after your ads run and charges are accrued. Your ads are served almost immediately after you submit valid billing information. For more details on how and when Google bills your account, please review the Billing Cycle lesson.

Payment methods for postpay:

  • Credit/Debit card: You can use a Visa, MasterCard/Eurocard, American Express, or JCB credit card, or a debit card with a MasterCard/Eurocard or Visa logo (accepted in all countries). This is the most popular and widely available billing option for AdWords advertisers.
  • Direct debit: Selecting this method authorizes Google to submit appropriate charges to your bank. Funds are withdrawn directly from your bank account once the advertising costs reach the criteria for billing (currently available only in Germany, France, Austria, Spain, and the Netherlands).

Qualifying AdWords advertisers can apply for monthly invoicing. Typically, an established payment history and minimum spending requirements (varying by country) are necessary. To learn more, please see the Invoicing lesson.

Prepay: Credit/Debit cards and Bank Transfer

Prepay requires advertisers to pay before their ads run and begin to earn charges. As users click on your ads, Google deducts the charges from your prepaid balance. To help keep your account balance up-to-date and your ads running, you'll receive emails when your funds run low and approach a zero balance.

Payment methods for prepay:

  • Credit/Debit card: If you choose this payment method, Google charges your credit or debit card in the amount that you specify. Your ads will begin running almost immediately after you enter valid credit/debit card information and specify a payment amount. You can use a Visa, MasterCard/Eurocard, American Express, or JCB credit card, or a debit card with a MasterCard/Eurocard or Visa logo (accepted in all countries).
  • Bank transfer: With this payment method, you transfer funds from your bank to Google. Transfers can take several weeks to process, so it's important to add funds before your balance draws too close to zero. Bank transfer is not available to advertisers in some countries, including the U.S.

Bank Transfer 

To pay for your advertising via bank transfer, you must first generate a reference number. Bank transfers can be initiated following these steps:

  1. Sign in to your AdWords account at https://adwords.google.com.
  2. Click the My Account tab, and then click Make Payments.
  3. Enter the amount of money you plan to transfer to your AdWords account in the Payment amount field, and click Go.
  4. Click Transfer Information page to view the details of your bank transfer. Here, you can access your reference number, the amount you entered for transfer, your account information, and the information of the bank to which the funds should be transferred.
  5. Click Print page in the upper or lower left corner of the page, and fill in the necessary information about your bank account in the space provided.
  6. Use the printed sheet, complete with your bank account information, to perform the transfer of funds at your bank. **It's very important that you include the entire reference number along with the bank transfer. We won't be able to process your payment without it. If you can't fit it on your bank's transfer form, insert the entire number in the 'Name' field before your name.**

Once Google receives the funds and complete reference number, we will send you a confirmation message via email, and your ads will start running on Google. It can take several weeks for Google to receive a bank transfer, depending on your bank's process.

Note that different countries may require different treatment of the reference number--you will be given instructions specific to your country.

Switching Payment Types & Currency 

Postpay advertisers may switch back and forth between available postpay options (credit card to direct debit, for example) as well as between different payment providers (such as Visa to MasterCard). Prepay advertisers may also switch back and forth between bank transfer and prepay by credit card, if the options are available in their country and currency.

It's currently not possible to switch from a prepay method to a postpay method, and vice versa. For example, it's not possible to switch from credit card prepay to direct debit. Similarly, once a currency has been selected, it's not possible to switch to a different currency. The currency selected applies to both billing and payment.

In order to change currencies or to switch from prepay to postpay, you must close your existing account and create a new account with the preferred currency.

AdWords and European Value Added Tax 

AdWords accounts with European Union billing addresses are subject to VAT charges. If you have an AdWords billing address within the European Union, this topic applies to you.

Billing Address in Ireland 

All EU advertisers are affected by VAT. Advertisers with billing addresses in Ireland are subject to different VAT implications than those with billing addresses in the rest of the EU.

  • Advertisers with an Irish billing address, and who have provided Google with a valid VAT registration number do not need to self-assess VAT charges. Google will automatically assess your account at the Irish VAT rate.
  • Advertisers with an Irish billing address who do not provide Google with a valid VAT registration number are also assessed at the current Irish VAT rate. The Irish VAT rate is subject to change per the Irish government's discretion.

Billing Address in EU, Outside Ireland 

If your billing address is outside of Ireland and you provide Google with a valid EU VAT number, Google will not charge VAT to your account. You must self-assess for VAT at the EU member country rate where your billing address is located.

However, if your billing address is outside of Ireland and you do not provide Google with a valid VAT registration number, Google will charge VAT to your account at the current Irish VAT rate. VAT charges will appear in your Billing Summary.

Providing Google with a VAT Number 

New advertisers are asked to provide VAT information during the account creation process. You can enter your VAT number at the bottom of the Edit Billing Preferences page. Current advertisers already registered for VAT in an EU member state can enter their registration numbers by following these steps:

  1. Log in to your account at https://adwords.google.com
  2. Click the My Account tab.
  3. Click Billing Preferences on the My Account tab.
  4. Select the appropriate VAT option and enter your VAT registration number.

 
 

4d. Invoicing

Invoicing Basics

Learn how invoicing works, and the standard criteria for invoicing eligibility.

Invoicing Prerequisites 

Typically, invoicing candidates have an established credit history with the Google AdWords program and a spending level of US $1500 per month for at least three months. If you meet these requirements, you may begin the application process.

What is Invoicing? 

Invoicing is an additional form of billing available to qualifying Google AdWords advertisers.

AdWords advertisers who meet certain requirements can apply for monthly invoicing. This billing option allows for payment on a monthly basis by check or wire transfer. Once approved for monthly invoicing, an advertiser's campaigns are no longer subject to suspension in the case of a declined payment.

The Application Process 

Monthly invoicing is offered at Google's sole discretion. Advertisers must first submit a credit application for review and approval by Google's finance team. In some cases, our finance team may request that you send your company's audited financials (balance sheet, income statement, cash flow statement and/or references) for further consideration.

If Google approves your application, you'll receive an offer of monthly invoicing via email as well as a request for confirmation of your billing address including company name, contact name, and address. You may then accept the terms by responding to the email. Once you accept the payment terms and confirm your billing address, your AdWords account will be switched from credit card billing to monthly invoicing.

Invoicing Prerequisites 

Typically, invoicing candidates have an established credit history with the Google AdWords program and a spending level of US $1500 per month for at least three months. If you meet these requirements, you may begin the application process.

 
 
Paying through Invoices

Learn how to determine an appropriate budget based on your credit limit, and how to submit invoice payments.

Determining Daily Budget 

Once accepting invoicing terms, an advertiser's combined daily budget cannot exceed 1/30th of their 30-day credit limit. To determine a rough estimate of what you may spend per day, divide your credit limit by 30.

For example, you have a credit limit of US$6000. Divide 6,000 by 30 to arrive at the estimated daily budget for all your campaigns. In this case, the combined daily budget for all of your campaigns should not exceed US$200. If the sum of your spending exceeds the maximum daily limit at any time, ad delivery will be slowed so you aren't charged more than your credit limit allows. Ads will be shown evenly throughout the day, but at a slower rate.

Making Payments 

Invoices are sent on approximately the fourth business day of each new month. When an invoice is sent, a new line item appears on the Billing Summary page, detailing the included charges. All payments are due upon receipt of invoice. Non-payment within 15 business days of the invoice date may result in account termination.
