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.

computer-generated pictures]
Every Monday someone copies last week's tab, pastes in the new numbers, and prays the
formulas hold.
There's a database from 2009 that runs half the shop, and nobody's allowed to touch it
because the guy who built it is gone.
The quote lives in one spreadsheet. The hours live somewhere else. The invoices live in
accounting. Nobody connects them — so nobody knows which jobs made money.
If one of those sounded like your Tuesday, keep scrolling.
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.
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.
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.
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.
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.
Working with something like this? Call or text me.
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.
Spreadsheet rescue / single automationtypically $2,500–$7,500
Where you land in the range depends on how your data arrives (Excel/CSV exports,
QuickBooks reports — we agree the format first); if it's messier than that, I tell you
before we start, not after, and quote the cleanup separately. Worked
example: rebuilding the broken nine-tab scheduling workbook in the demo above
would run about $4,500 and take three weeks.
An internal tool (job tracking, quoting, inventory)typically $5,000–$25,000
Scoped in writing, with what's included — and what isn't.
Every build includes a 60-day warrantyincluded
If something I built breaks, I fix it free, and you hear back within one business day —
both written into the contract, not promised in an email.
Keep-it-running support (optional)$500–$2,000/month
Nothing I build needs me to survive: it's boring, documented, mainstream tech any
developer can maintain. The retainer is for changes and new ideas, not life support.
First step, if you want one: a look-under-the-hood session[FILL: e.g. $250], flat
One hour with your actual spreadsheet or process; you get a written plan and an exact
fixed quote. Credited toward any build.
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.

How it works
Four steps, no mysteries.
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.
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.
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.
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.
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.

I work on a contract basis and take a limited number of builds at a time — so every build
gets a realistic schedule, in writing, before work starts.
Based in Hudson. I work within about 35 minutes — Nashua, Manchester, Lowell, Lawrence, and the
towns between. (A sketch, not a survey.)
