Excel model audit and repair

You send a spreadsheet model. I check its formulas, links, inputs and logic, list what is broken or risky, and, depending on the tier, fix it.

The problem

Models grow over time. Hard-coded numbers end up inside formulas, ranges stop short of new rows, links point to old files, and nobody is fully sure the totals are right.

An audit checks the model cell by cell where it matters, and gives you a written list of issues, each with its location, why it matters and how to fix it.

Turnaround is in business days and starts once I have your workbook and a line on what the model is used for.

Questions

What kinds of models do you audit?

Financial models, budgets, forecasts, pricing models and operating trackers built in Excel or Google Sheets. Macros (VBA) are reviewed only for what they change, not rewritten.

Do you change my original file?

No. The Health Check makes no changes. In the other tiers, fixes go into a copy, with a change log so you can see every edit.

Will you check my assumptions?

I check that the model calculates what it says it does. Whether an assumption is right for your business is your call, but I'll flag any that look inconsistent with the rest of the model.

Is the model kept confidential?

Yes. Your file is shared only with you. If you need an NDA, ask before you start.

Can I get a refund?

Email me before work starts and we'll sort it out. Once work has started, refunds are handled case by case.
