Invoice

Monthly invoices for a Google Ads account can be retrieved using the InvoiceService.

Prerequisites

  • Have monthly invoicing enabled for the Google Ads account. See the guides on account billing setups and budgets to learn how to manage billing using the Google Ads API.
  • If set, login-customer-id must specify the customer ID of a manager account that is managing the Google Ads account for which you're retrieving invoices. This is labeled as the paying manager in the Google Ads UI.

Retrieving invoices

To retrieve invoices, you need to request the InvoiceService.ListInvoices method setting all the required fields in the ListInvoicesRequest: customer_id, billing_setup, issue_year, and issue_month.

Here is an example:

Java

// Issues the request.
ListInvoicesResponse response =
    invoiceServiceClient.listInvoices(
        String.valueOf(customerId),
        ResourceNames.billingSetup(customerId, billingSetupId),
        String.valueOf(oneMonthAgo.getYear()),
        MonthOfYear.valueOf(oneMonthAgo.getMonth().toString()));
GetInvoices.java

C#

ListInvoicesResponse response = invoiceServiceClient.ListInvoices(customerId.ToString(),
    ResourceNames.BillingSetup(customerId, billingSetupId),
    // Year must be 2019 or later.
    lastMonthDateTime.Year.ToString("yyyy"),
    lastMonth);
GetInvoices.cs

PHP

// Issues the request.
$response = $googleAdsClient->getInvoiceServiceClient()->listInvoices(
    ListInvoicesRequest::build(
        $customerId,
        ResourceNames::forBillingSetup($customerId, $billingSetupId),
        // The year needs to be 2019 or later.
        date('Y', $lastMonth),
        MonthOfYear::value(strtoupper(date('F', $lastMonth)))
    )
);
GetInvoices.php

Python

# Issues a request to list invoices.
response = client.get_service("InvoiceService").list_invoices(
    customer_id=customer_id,
    billing_setup=client.get_service("GoogleAdsService").billing_setup_path(
        customer_id, billing_setup_id
    ),
    # The year needs to be 2019 or later, per the docs:
    # https://developers.google.com/google-ads/api/docs/billing/invoice?hl=en#retrieving_invoices
    issue_year=str(last_month.year),
    issue_month=last_month.strftime("%B").upper(),
)
get_invoices.py

Ruby

# Issues a request to list invoices.
response = client.service.invoice.list_invoices(
  customer_id: customer_id,
  billing_setup: client.path.billing_setup(customer_id, billing_setup_id),
  # The year needs to be 2019 or later.
  issue_year: last_month.year.to_s,
  # '%^B' option returns the uppercased full month name (e.g. 'JANUARY').
  issue_month: last_month.strftime("%^B").to_sym,
)
get_invoices.rb

Perl

# Issue the request.
my $response = $api_client->InvoiceService()->list({
    customerId   => $customer_id,
    billingSetup =>
      Google::Ads::GoogleAds::V18::Utils::ResourceNames::billing_setup(
      ($customer_id, $billing_setup_id)
      ),
    # The year needs to be 2019 or later.
    issueYear  => strftime("%Y", @last_month),
    issueMonth => uc(strftime("%B", @last_month))});
get_invoices.pl

The response is a ListInvoicesResponse object that contains the list of matching Invoices, each of which contains a large set of fields such as:

  • IDs: payments_account_id, payments_profile_id.
  • Time: issue_date, due_date, service_date_range.
  • Amounts: subtotal_amount_micros, tax_amount_micros, total_amount_micros.
  • PDF: pdf_url. See downloading an invoice PDF for instructions.
  • History: corrected_invoice, replaced_invoices.

It also contains other specific fields when relevant:

  • Adjustments: adjustments_subtotal_amount_micros, adjustments_tax_amount_micros, adjustments_total_amount_micros.
  • Regulatory costs: regulatory_costs_subtotal_amount_micros, regulatory_costs_tax_amount_micros, regulatory_costs_total_amount_micros.
  • Export charges: export_charge_subtotal_amount_micros, export_charge_tax_amount_micros, export_charge_total_amount_micros.

Getting budget details

An Invoice provides detailed information about related account budgets as a list of AccountBudgetSummary objects in the account_budget_summaries field:

  • IDs: customer, account_budget, purchase_order_number.
  • Time: billable_activity_date_range.
  • Amounts: subtotal_amount_micros, tax_amount_micros, total_amount_micros, invalid_activity_amount_micros, billed_amount_micros, served_amount_micros, overdelivery_amount_micros.

Getting account details

An Invoice provides information about related accounts as a list of AccountSummary objects in the account_summaries field. It includes details about billing corrections, adjustments, export charges, and regulatory costs.

Understanding amounts

All the amounts provided in AccountBudgetSummary, AccountSummary and Invoice objects are attributable during their service periods and are evaluated according to these rules:

Downloading an invoice PDF

Any invoice can be downloaded as a PDF file. Once you have retrieved the Invoice, you need to send an HTTP request for the URL that is stored in its pdf_url field. This request must be authenticated using the same Google account used to retrieve the invoice; that is, you need to specify an OAuth access token generated using the Google account in the Authorization: Bearer request header:

curl --request GET \
     --header "Authorization: Bearer access token" \
     Invoice.pdf_url > filename.pdf

The result is an invoice PDF content stored in the file filename.pdf.
