Still running the business on a fragile spreadsheet?

Somewhere in your business a workbook is doing the job of real software: pricing, inventory, scheduling, orders, payroll. It worked when it was one person and one tab. It doesn’t any more. We build the custom back-office software to replace it, starting with a fixed-price audit of what the spreadsheet is actually doing.

Symptoms

Does this sound familiar?

01

Someone fat-fingers a cell and nobody notices until the numbers don't add up at month end.

02

There's no audit trail: you can't say who changed what, or when, or why.

03

Three people have their own copy, and none of them agree with each other.

04

It breaks the moment the one person who understands the macro goes on holiday.

05

“Version_FINAL_v3_useTHISone.xlsx” is a real file that real decisions get made from.

06

It technically works, so nobody's allowed the budget to fix it, until it doesn't.

What we build instead

Software built for how you actually work.

Not an off-the-shelf tool you have to bend your process around. Not a rebuild for its own sake. Custom back-office software scoped to what your business actually needs, with the spreadsheet’s real logic kept and its real flaws designed out.

A proper data model: one source of truth, not a workbook everyone copies and edits in parallel.

Permissions and an audit trail: who can see what, who changed what, and when.

Validation and automation built in, so the errors a spreadsheet lets through can't happen at all.

Software that survives the one person who understood it leaving the business.

How it works

Audit the spreadsheet, then replace it properly.

01
Week 1
Audit

We look at what the spreadsheet actually does versus what everyone assumes it does. Fixed price, $7,500, one week.

02
Same week
Specify

The audit becomes a written spec: the data model, the workflows, the permissions, every module priced separately before you commit to a build.

02
03
4–10 weeks
Build & harden

Real engineering against the approved spec, tested as we go, delivered in the open rather than as a year-long “transformation project”.

03

The build itself is our Production build service: from $30,000, 4 to 10 weeks, priced module by module against the approved spec.

Pricing

Audit from $7,500, build from $30,000.

The spreadsheet audit is a fixed-price, one-week engagement that turns into a written specification. Building the replacement is our Production build service, priced module by module before we start.

Bring the spreadsheet. We’ll tell you straight.

Worst case, you leave with a clearer picture of what it's actually costing you. Best case, it's a smaller job than you feared.
