Monthly invoicing is a way of paying for Google Ads in which Google gives you a line of credit and sends an invoice each month for the advertising you ran, instead of charging a card as costs build up. You then pay the invoice, usually by bank transfer, within the agreed terms.
How monthly invoicing works
Most accounts start on automatic payments, where Google charges your card or bank account when costs reach a billing threshold or a set number of days after the last charge, whichever comes first. Monthly invoicing is a different arrangement that you apply for through the billing section of your account. Google decides who qualifies using its own criteria, which typically look at how long you have advertised and your spend and payment history; it does not publish a single fixed threshold, and the criteria can change.
Once approved, the account runs on account budgets: you set an amount and a start and end date, and ads stop when the budget is used up or the end date passes. Each month you receive an invoice in your billing currency, which for a UK business is normally pounds sterling, and pay it by the due date. Invoices can be set per account or, for groups of accounts under a manager account, consolidated into one.
The billing details all sit in your payments profile: business name, address, VAT number and the people who receive invoices. Microsoft Advertising offers a similar invoiced arrangement for eligible advertisers.
Why it matters
For larger accounts, card payments become awkward: dozens of charges a month, card limits that stop ads when reached, and receipts that finance teams must match one by one. A single monthly invoice fits the way most UK finance departments already pay suppliers, with purchase order numbers and payment runs.
Invoices also make tax simpler. Your accountant needs to see whether UK VAT is charged on the invoice or whether the reverse charge applies, which depends on the Google entity billing you and on your VAT registration, so check the invoice rather than assuming. The details are covered under VAT on digital advertising. Since late 2020 Google has also added a separate fee to recover the UK Digital Services Tax on ads shown in the UK, listed as its own line; check a current invoice to see whether and how it still applies.
Common mistakes
- Letting an account budget run out or reach its end date, which stops every ad until a new one is approved.
- Paying late, which can lead Google to suspend ads on the account.
- Registering the payments profile without a VAT number or with the wrong legal business name, so invoices do not suit your bookkeeping.
- Not adding a purchase order number to the account budget when your finance team requires one.
- Sending invoices to an inbox nobody watches, such as the address of a former employee or agency.
How to act on it
If you spend steadily on Google Ads and card payments are causing friction, check whether monthly invoicing is offered in your billing settings and apply. Before switching, confirm the business name, address and VAT number in the payments profile, decide who receives invoices and set up a reminder well before each account budget ends.
Agree internally who owns the budget, because with invoicing the card limit no longer acts as a backstop. When I run an account through monthly PPC management, the billing and budget dates sit on the same checklist as the campaigns, because a lapsed budget switches ads off just as surely as a policy problem.
