I built ScopeLedger to turn “one more thing” into a clear scope conversation

Description and use

ScopeLedger is a local tool that uses a Gemma model to classify new client requests against agreed deliverables, providing source citations and a draft change‑order.

Problem

Freelance developers and small agencies struggle with unplanned client requests that inflate scope without agreed payment.

Outcome

ScopeLedger demonstrates that a local, open‑weight Gemma model can assist in scope management, producing draft change‑orders with source citations. Validation on synthetic cases shows 6/8 matches with the revised 4B prompt, and a live local run produced a $500 draft quote.

Workflow

• Paste agreed deliverables and new client requests into the app
• The local Gemma model classifies each request and provides source lines
• Review and override classifications, estimate effort, set rate
• Select changes to include in the quote
• Export a change‑order draft
• (Optional) Adjust pricing or request clarification before finalizing
• (Optional) Use the guided demo or run locally with Ollama

Evidence

Paste the agreed deliverables beside the client’s new requests. A local Gemma model proposes which asks are included, which may be additional work, and which need a conversation.

Source

The application code handles what should be deterministic: request IDs, source citations, complete coverage, owner approval and pricing.

Gemma 3 4B, revised matched 6 of 8 development cases.

The prototype still has limits. It needs short, atomic text lines. It does not parse PDFs, track historical revision usage or establish legal obligations.
