The report works, but it is difficult to change or maintain safely.
Service
Reporting Review & Fix
If an existing Excel or Power BI solution is slow, fragile, hard to maintain, or producing problems, I diagnose it before pricing the fix.
Problem
I already have an Excel or Power BI solution, but it is slow, fragile, confusing, difficult to maintain, or producing problems.
When this service is useful
Refresh, file dependencies, Power Query, the model, or DAX are causing problems.
You do not want to commit to an open-ended repair project before the problem is understood.

Stages
Stage 1 — Review
Diagnose the existing solution and provide concrete recommendations.
Stage 2 — Fix / implementation
Optional implementation of selected changes, scoped and priced separately after the review.
Scope boundaries
The review is a standalone paid deliverable.
Implementation is quoted separately only after the review.
The review does not include unlimited fixes to an unknown legacy solution.
How the project starts
You show the existing solution and the problems you are seeing.
I define the scope of the paid review with you.
After the review you receive findings and recommendations; selected fixes can then be quoted separately.
Commercial model
The review is fixed-price; implementation is quoted separately after the existing solution is understood.
