Ad spend accruals at month end: how marketing and finance reconcile platform spend and invoices

Ad platforms bill in arrears, in their own currency and on their own calendar, and they adjust amounts after the fact. Finance closes the month on a fixed date and needs a number it can defend. Marketing knows the spend in real time but often not in the form finance needs: by legal entity, cost centre, purchase order and currency.

The result in many companies is the same email every month: "what should we accrue for Google, Microsoft and LinkedIn?" followed by a scramble through three ad accounts. This article is general information on how the numbers fit together, not accounting advice; your controller sets the policy.

Check the billing terms in your own accounts: invoicing eligibility, terms and thresholds vary by account and country, and the LinkedIn FAQ we cite is an older page that was still live when we checked.

• Timing: the month’s invoice arrives days after close, so the accrual is an estimate by design.
• Overdelivery: Google can serve more than the spending limit allows but says you never pay above the limit; its billed cost report shows billed cost next to served cost, and the difference is overdelivery.
• Credits and adjustments: Google lists invalid activity credits with the original month of service, so a credit received in November can relate to September.
• Currency: each Google Ads account bills in the currency set at creation; if you book in another currency, the rate and date you use change the number.
• Time zone: reports follow each account’s time zone, so a campaign’s calendar month in Eastern time and a finance calendar in another zone cut at different hours.

A Google Ads account billed in US dollars, booked by a Canadian company in Canadian dollars. All numbers are example inputs for illustration.

The October accrual should match October billed cost, not the invoice total, because the credit belongs to September. Whether the credit is booked in November or applied back to September is a policy choice for finance; what matters is that it is labelled, not netted silently. The FX difference between the accrual rate and the payment rate is a finance entry, not a marketing variance.

1. Agree the rules once: cut-off time zone, which cost the accrual uses (billed where available), currency rate source and date, and how credits are treated.
2. Map every ad account to a legal entity, cost centre and purchase order; name campaigns so PO numbers can be read from them where the platform supports it.
3. On the last day of the month, export or freeze spend by account and campaign in account currency, with the time of the pull.
4. Finance books the accrual per account from that report; marketing confirms any known overdelivery, credits or late changes.
5. When invoices arrive, reconcile invoice to accrual per account: timing, overdelivery, credits, currency, taxes.
6. Record each reconciling item with its cause, so recurring differences are fixed at the source.

Most of the month-end friction comes from finance seeing the numbers only once, after the month is over. A live, read-only report of spend by account and campaign, in account currency, with the month-end forecast next to it, changes the conversation: finance can see the accrual forming during the month, flag a purchase order that will be exceeded on day 12 rather than day 35, and stop asking for exports.

It also connects to the budget conversation. A finance team that has watched pace and forecast all quarter is far easier to work with when marketing asks to move budget, which is the heart of defending the budget to the CFO.

Pacing Console is a pacing tool, not an accounting system, and it shows the cost the ad platforms report rather than invoices. What it gives finance is the live picture the accrual starts from: read-only live report links that need no login, a live Google Sheets link (IMPORTDATA) and CSV export, budgets in CAD, USD, EUR, GBP or AUD, and a month-end forecast for every campaign.

Every plan includes these. Enterprise adds purchase orders, budget groups, approvals and an audit log, so the PO a campaign spends against and who approved each budget change are recorded in the same place. The first month is free.
