When to Adopt Mowgli: Credit-Forecasting Before You Sign a Fixed-Fee App Retainer

Can our agency commit to a fixed-fee client app design retainer on Mowgli without the credit-based generation model eating the margin? Model credit burn per client screen count before quoting a fixed fee, and only adopt Mowgli when the projected iteration volume fits inside the plan tier you are billing against.

“Can our agency commit to a fixed-fee client app design retainer on Mowgli without the credit-based generation model eating the margin?”

Model credit burn per client screen count before quoting a fixed fee, and only adopt Mowgli when the projected iteration volume fits inside the plan tier you are billing against.

Common Mistake

Treating Mowgli like a flat-rate design tool and quoting fixed-fee retainers from screen count alone, then discovering mid-sprint that chat-driven iteration has drained the client's credit pool and the agency is now funding revisions out of its own margin.

Why This Works

Mowgli's credit-based generation model means every design iteration consumes credits, and the verdict flags that clients on fixed retainers may hit limits unpredictably if scope creeps. The Free plan's 300 credits and Starter's 6,000 credits/year are finite pools, so an agency that quotes a flat $3,500 MVP build without mapping screen count to credit consumption absorbs the overage itself. The Team plan at $49/seat/year adds shared folders and 12-hour support, which matters for multi-client delivery, but it does not remove the credit ceiling.

Apply When
  • •You are scoping a client app UI of roughly 20 screens, matching the Mowgli MVP App Design offer priced at $3,500 with a 24h setup window.
  • •The client will need more than 6,000 credits per year of iteration, which is the ceiling on the Starter plan at $12/month billed annually.
  • •Your delivery team needs shared folders and 12-hour support response, which the Team plan at $49/seat/year provides.
  • •The client already has Figma files or a codebase and expects bidirectional sync through the Figma import and MCP coding-agent connection (Claude Code, Codex, Cursor).
  • •You are running two or more concurrent client app builds and need to know which workspace consumes which credits.
