Anthropic Rule: Cap Claude Token Spend Before You Quote a Fixed Retainer
Can my agency sell Claude-powered client work on a fixed-price retainer without the token bill eating the margin? Price Claude work on metered token consumption or a hard usage cap, never on an uncapped flat retainer.

“Can my agency sell Claude-powered client work on a fixed-price retainer without the token bill eating the margin?”
Price Claude work on metered token consumption or a hard usage cap, never on an uncapped flat retainer.
Quoting a flat monthly fee after testing only on the Free tier or a single Pro seat at $20, then discovering that a high-volume client's token consumption on the Max plan at $200/mo erases the retainer margin in the first billing cycle.
Claude bills on input and output tokens that vary by model, and the verdict flags that this consumption model makes predictable client retainer pricing difficult without usage caps. The Free tier covers web chat, code generation, and web search, while Pro at $20 monthly (or $17 monthly billed annually) adds Claude Code and Claude Cowork, and Max at $200/mo raises throughput to 200+ requests per minute, so the cost curve tracks usage rather than seats. Agencies also cannot white-label the interface, which limits how much of the markup can be justified as product rather than labor.
- •The client deliverable is content generation, document analysis, or coding assistance billed as a flat monthly fee rather than metered usage
- •The agency is weighing the Pro tier at $20 monthly (or $17 monthly billed annually) against the Max plan at $200/mo for 200+ requests per minute
- •Projected client volume exceeds the Free tier's web chat, code generation, and web search limits, so paid API consumption is unavoidable
- •The engagement runs longer than 90 days and the client expects a predictable invoice each month
- •No usage cap, token budget, or overage clause exists in the current statement of work
