AI slipped into the retainer. The cost slipped into overhead.
Every service now uses AI
Briefs, captions, research, reporting. Each one calls a model, often from a different tool, on a key the whole team shares.
One bill, twenty clients
The provider invoice covers every account manager’s work for every client. Nobody can say which retainer the cost belongs to.
Retainers priced on a guess
You priced the AI line before you had seen a real number. Some clients are subsidizing others, and you cannot tell which.
Small per client. Large across the agency.
Three dollars a day per client is nothing. Thirty clients for a year is a salary, paid out of margin, and never shown to the clients who caused it.
per client is about $33,000 a year across thirty retainers, unattributed.
shared across the content team, so one client’s campaign spike looks like everyone’s.
line items you can show when a client asks what the AI in their retainer cost.
A key and a budget per client, from the first brief.
Set up each client once. Every tool your team uses for that client runs on that client’s key, and the spend rolls up to a number you can bring to the retainer review.
See what each retainer’s AI costs
Live spend per client, per project and per model. Price the AI line in the next renewal on the real number.

New retainer, new client, new key. Lose a client, revoke the key, and nothing else moves.
