Sound familiar?

It's held together with hope

One wrong cell and the whole thing breaks. Nobody knows why it works — they just don't touch it.

You inherited someone else's mess

The person who built it left. Now it's your problem, and there's no documentation anywhere.

It takes too long every week

Copy-pasting, manual calculations, reformatting — tasks that should take minutes take hours.

You need it built from scratch

You know what you need it to do, but you don't know how to build it. Start from a brief.

Good for
Pricing sheets Quoting tools Job trackers Back-costing sheets Stock or inventory sheets Fuel or mileage logs Timesheet summaries Simple dashboards Monthly reporting sheets Training or compliance trackers Inherited spreadsheets no one wants to touch

Have a client spreadsheet that makes your job harder?

Some client spreadsheets have been patched together over years. They sort of work, but they take too long, create errors, or make monthly reporting harder than it needs to be.

SheetFix can clean up the file, simplify the structure, fix formulas, and hand it back with plain-English instructions so your client actually understands how to use it.

If a spreadsheet is causing repeated problems for you or your client, submit a brief or email SheetFix to discuss.

For building companies

Growing faster than your spreadsheets can keep up?

Most building companies run on a patchwork of sheets — one for quoting, one for job costing, one that only one person understands. It works, until it doesn't.

SheetFix builds the trackers and tools that keep a growing building company on top of the numbers:

  • Job costing tracker — see quoted vs actual on every job, so you know where the margin's actually going
  • Quoting calculator — labour, materials, overheads and margin, built in — no more guessing
  • Subcontractor register — rates, insurance, licence expiry, all in one place
  • Cash flow forecaster — claims, retentions, wages and supplier payments, mapped out weeks ahead
  • Tender scorecard — stop burning hours pricing jobs you were never going to win

If it's a spreadsheet problem, SheetFix can fix it or build it — submit a brief or email SheetFix to talk through what you need.

Describe it. SheetFix will diagnose it.

Takes about 5 minutes. You'll get an instant AI analysis of your situation — no commitment, no calls.
