Fix the agency contract before the 2027 budget closes
Budget season is when teams argue about how much to spend, not what it buys. Once the 2027 number is signed, the agency contract rolls forward on old terms.
Budget season is when marketing teams argue about how much to spend. It is rarely when anyone asks what the money buys. That's backwards. Once the 2027 number is signed, the agency contract governing about a fifth of it rolls forward on the same terms, and the room you had in September is gone by February.
The numbers make the case. Gartner's 2026 CMO Spend Survey puts marketing at 7.8% of revenue, with agencies taking 19.2% of the budget and paid media 31.4%. More than half of CMOs, 56%, said they lack the budget to deliver their 2026 strategy. If the budget won't grow, the room has to come from what it already pays for.
Why this year is different
- AI changed what agency work costs to deliver. In Forrester and the 4As' 2026 study, 90% of US agencies use generative AI and 61% classify it as a cost of doing business rather than something they bill for. The hours in your scope may not be the hours being worked.
- The agency market is consolidating. Omnicom closed its acquisition of IPG in November 2025, announced more than 4,000 job cuts and folded DDB, MullenLowe and FCB into other networks. WPP has cut about 11,000 jobs since the start of 2025 and is bringing Ogilvy, VML and AKQA under one creative unit. Dentsu has completed about 3,000 of the 3,400 international cuts it announced in 2025. The team in your contract may not be the team on your account.
- Advertisers are rewriting pay models. A WFA study of 69 multinationals, published in October 2026, found labor-based fees are now the main model for only 19% of them. 20% have already changed agency commercial models because of AI, and 61% intend to.
- Contracts are catching up, unevenly. The ANA's 2026 transparency survey found 89% of advertisers updated agency contracts within two years, but only 54% added rebate clauses.
Five terms to fix before you sign off the budget
- Scope tied to outputs, not hours. If AI cut the hours, the fee should reflect it.
- Named senior people with committed time. Write in who you are paying for, and what happens if they leave.
- Audit rights across affiliates. Money can move through trading desks and group companies, not just the agency you signed with.
- Principal media by written opt-in. Per buy, with the margin disclosed.
- An annual reconciliation. Fees, rebates and pass-through costs checked against the contract.
None of these needs a pitch. They need a letter before the budget locks and a renewal date on the calendar.
The sequencing that works
Set the 2027 number with agency fees as a line to be confirmed, then renegotiate inside it. Agencies plan their own 2027 staffing on the same calendar, and after the year the holding companies have had, most are planning cautiously.
We have sat on the agency side of the September conversation. The clients who arrived with a clear redline got moved first. The ones who arrived in March with a complaint got a meeting.

When should we renegotiate our agency contract?
Before next year's budget is signed. Once the number is locked, the agency has little reason to move and you have no room to absorb a change.
What has changed in agency economics since 2024?
AI has changed what agency work costs to deliver, the holding companies have consolidated and cut staff, and advertisers are moving away from labor-based fees toward output and performance models.
Which agency contract terms matter most right now?
Scope tied to outputs rather than hours, named senior staff, audit rights across affiliates, principal media by written opt-in, and an annual reconciliation of fees, rebates and pass-through costs.
Do we need to run a pitch to get better terms?
Usually not. Most improvements come from a clear redline sent before the budget closes, not from a search.
That is usually the first sign there is money in it. If your agency contract predates your AI budget, fifteen minutes is enough to tell you which terms to reopen first.
