Your business runs on a spreadsheet that's one bad paste away from breaking.

I'm Addison Nute, in Hudson NH. I turn load-bearing spreadsheets, double-entered numbers, and systems that won't talk to each other into small, reliable software you own outright — with prices listed right on this page and fixed in writing before work starts.

The work

Four builds on the bench, shown warts-and-all.

All four are demonstration pieces on realistic sample data — no client's real numbers are on this site. You can poke every demo, and nothing asks you for anything.

for anyone with a workbook like this

Spreadsheet Rescue

The workbook only one person understands, rebuilt into a small app anyone can use — merged cells, broken formulas, the hidden tab and all.

Inside the demo: download the broken workbook and check my work — it's a realistic sample, built to break the way real ones do. No client's real numbers on this site.

The old workbook depended on one person who left. The rebuild can't: you own the code, the accounts, and a plain-English manual from day one. Here's exactly how.

for shops that quote

Margin X-Ray

Find out which jobs you actually made money on — your quotes, your timesheets, and your invoices finally agreeing with each other.

For contractors: the post-job autopsy that shows where the estimate and the build parted ways — flip the switch inside the demo.

It shows its homework: how it matched your quotes, timesheets, and invoices — and the few matches it wasn't sure about, for you to confirm. No black boxes.

The Monday Report

One plain-English email every Monday morning: what came in, what went out, and the one number that needs your attention this week.

For practice offices: a second edition that works entirely in totals and counts — no patient information anywhere, including behind the taps.

It's a sample report on sample data, and says so on its face. Tap any sentence and it shows the rows and arithmetic behind the number. The version that reads your books is a client engagement — your accounts, your credentials, your rules.

for anyone who buys from the same suppliers every week

Price-Creep Watchdog

Catches the quiet 6% your suppliers add when nobody compares this year's invoice line to last year's — even when they rename the part.

Line items in the demo are pre-extracted; the matching and the math run live in your browser — every pairing shows its confidence, and the lines it wasn't sure about wait in a visible queue for you to judge. No match-rate claims.

Four builds are on the bench. One more is in the shop — a dead-stock finder. Ask me about it.

Prices

What things cost

Typical ranges below; your exact price is fixed in writing before work starts — and once it's in writing, it doesn't move.

New practice — no testimonials yet. That's why the prices, the contract, and a working demo are all on this page.

First three builds: [FILL: founding-client discount, e.g. 25%] off, in trade for a written, named case study.

How it works

Four steps, no mysteries.

  1. You show me the problem. Call or text. If you want a priced first step, the look-under-the-hood session is one hour with your actual spreadsheet or process — [FILL: e.g. $250] flat, credited toward any build.
  2. I put it in writing. You get a written plan, a realistic schedule, and an exact fixed quote. Once it's in writing, it doesn't move.
  3. You get working software. Built to the written scope, with a 60-day fix-it-free warranty and a one-business-day response — both in the contract.
  4. You own all of it. The code, the accounts, the domain, and a plain-English manual — yours from day one, handed over in a folder you can actually read.

Own it

When I'm done, you hold the keys.

The code, the accounts, the domain, and a plain-English manual are yours from day one. Here's exactly what a handover looks like: a real example handover folder you can browse. And here's the actual contract you'd sign — download it, read it at your kitchen table, no email address required.

I do this work on a contract basis and take a limited number of builds at a time. You get a realistic schedule up front, in writing.

Fair questions

The ones you were going to ask anyway.

"What if you get hit by a bus?"
Fair question; it's the right one to ask anyone like me. Everything I build is boring, documented, mainstream technology. You own the code and every account from day one, and the handover folder includes a manual written for the next developer — whoever that is. See exactly what you'd be holding: the example handover folder.
"What happens when it breaks the week you're slammed?"
Every build comes with a 60-day fix-it-free warranty and a one-business-day response commitment — both in the contract, not in a promise. After 60 days the optional support plan covers it, and because you own the code and the manual, any developer can step in if you'd rather not wait for me.
"Are you available full-time?"
No, and I won't pretend to be. I work on a contract basis and take a limited number of builds at a time. What you get instead of a body in a chair: a fixed price, a written schedule, and software that doesn't need me to keep running.
"Why are your prices on the page?"
Because nobody else's are, and you were going to ask anyway.
"Do you use [whatever's in the news]?"
I use whatever tool does the job and costs you the least to own. The fancy parts, where they exist, are described on each project's "How it's built" page.
