How the trap works

Vendor offers a low headline retainer. Token consumption is "your responsibility". As usage scales, the buyer absorbs 100% of the variable cost. We have seen six-figure surprises in the first quarter post-signing.

What good looks like

Per-token pricing is fine if it is capped, reviewed, and bounded by 30-day notice. Buyers need a lever to renegotiate as usage grows. Vendors who refuse caps are pricing for uncapped upside.

The four clauses

Monthly cost cap. Quarterly cost review. 30-day cost-change notice. Itemised ongoing cost. These four clauses transform a token-pass-through engagement from a CFO trap into a manageable spend.

Real case examples

Anonymised cases in our scorecard PDF: a SaaS company that absorbed a 4x usage spike, a fintech that re-negotiated mid-quarter, and a logistics buyer that walked away when the vendor refused a cap.
