Sheet-Pay: When Spreadsheets Become a Bottleneck

Most businesses start with spreadsheets for expense tracking. It works until it doesn't. Here's the pattern we see and what to do about it.

The Spreadsheet Trap

A social enterprise was managing CSR project expenses across multiple programs. They had spreadsheets. Lots of them. Each project manager maintained their own. The finance team consolidated manually every month.

It worked when they had 3 projects. Then they grew to 15.

What Was Breaking

No Single Source of Truth

Each project had its own spreadsheet. Finance spent 2 days/month just consolidating.

Approval Chaos

Expenses emailed back and forth. "Did you approve this?" conversations daily.

Missing Documentation

Invoices attached to emails. Some lost. Audit prep was a nightmare.

No Audit Trail

Who approved what, when? Nobody knew without digging through email threads.

What We Built

Sheet-Pay was a simple web application that replaced the spreadsheet chaos with a structured workflow. Not fancy. Just functional.

Signs You've Outgrown Spreadsheets

  • More than 5 people need to access/update expense data
  • You spend hours consolidating data from multiple sheets
  • Approval workflows happen over email
  • Finding a specific invoice requires digging through folders
  • Audit prep takes more than a day
  • You've had duplicate payments or missed approvals

If you ticked 3 or more, a structured system will save you time and headaches.
