I fix the spreadsheets your business runs on.

Cleanup, reporting, and data migration for small businesses — at a fixed price you know before I start, delivered in days rather than months.

The problem

You already know which file I'm talking about.

Someone built it four years ago. It has tabs nobody fully understands, a formula that quietly breaks whenever a row gets inserted, and two columns that are supposed to match but don't. Half the team is afraid to touch it.

And your business runs on it anyway — inventory, billing, payroll, the month-end close. So the question isn't whether it's worth fixing. It's who has three uninterrupted days to actually do it.

That's the job. I take the file, find out what's actually wrong with it, fix it, and hand it back documented — so the next person who opens it can tell what it's doing.

How it works

Four steps, and you know the price at step two.

Send me the file

Along with one sentence about what's going wrong. Twenty minutes on the phone if it's easier to explain out loud.

I quote a flat fee

A fixed price and a delivery date, before any work starts. If it isn't worth it, I'll tell you that instead.

I do the work

Half up front, half on delivery. You'll hear from me if I find something you ought to know about.

You get it back documented

The fixed file, plus a plain-English note on what was broken — so it doesn't quietly break the same way again.

Who you'd be working with

I spend my working life on data integrity — reconciling records across systems, configuring data feeds, and migrating millions of transactions between platforms without losing any of them. Fixed income, derivatives, FX, structured products: the kinds of data where a quietly wrong number is an expensive problem.

CM Data Co. applies the same discipline at small-business scale. Most spreadsheet problems aren't really spreadsheet problems — they're reconciliation problems wearing a different hat. Two sources that should agree, don't, and nobody has the time to find out why.

Send me the file. I'll tell you what it'd cost.

No charge for the look, and no obligation after it. If the fix isn't worth paying for, I'd rather tell you that than take the job.
