Client AI Cost Envelope Review (Retention)

Client AI Cost Envelope Review (Retention)

1. 01

   Pull 90 days of per-client token and compute spend from the gateway or billing export

   Segment by model, endpoint, and environment so retainer-level totals can be traced to specific deliverables rather than a single blended invoice line.

2. 02

   Compare realized spend against the cost envelope written into the retainer or SOW

   Flag any client running above 80 percent of envelope with more than 30 days left in the period; that is the window where a re-scope conversation is still friendly.

3. 03

   Identify the three highest-cost request patterns and test cheaper substitutes

   Route summarization and classification traffic to a smaller model through a gateway such as Helicone or Portkey, and keep frontier models for reasoning-heavy calls only.

4. 04

   Check whether caching and rate limits are actually enabled on repeat queries

   Agencies routinely pay twice for identical prompts; response caching on stable client FAQs often removes a double-digit percentage of monthly spend without touching output quality.

5. 05

   Document who controls pricing, access, and dispute resolution for each provider in the stack

   Forrester's November 2026 research flags vendors holding the meter, the gate, and the referee role at once; note which relationships carry that concentration before renewal.

6. 06

   Model a 20 percent price increase scenario and confirm the retainer still clears margin

   Run the same scenario against a second provider, since multi-model orchestration is the only structural hedge against a single vendor's pricing shift.

7. 07

   Send the client a one-page cost and reliability summary with the next quarter's envelope

   Include spend trend, latency, and any model swaps made; this turns infrastructure hygiene into a visible retention touchpoint instead of a surprise invoice.
