I walk into businesses every month and find the same thing: a critical spreadsheet — payroll tracking, loan amortization, job costing, inventory — that only one person knows how to use. If that person is out sick, on vacation, or quits, the business grinds to a halt. And nobody realizes the risk until it happens.

That’s not a system. That’s a liability.

Signs your spreadsheet has become a problem:

  • It’s the source of truth for financial data that should live in your accounting system. If someone has to manually move numbers from Excel into QuickBooks, errors are guaranteed.
  • It requires specialized knowledge to maintain. Formulas that break if you insert a row. Tabs that reference other tabs that reference other files. Nobody wants to touch it.
  • It’s grown far beyond its original purpose. It started as a simple tracker and now runs half your operations.
  • There’s no backup plan. If the file gets corrupted or the person who built it leaves, you’re starting from scratch.

The fix isn’t another spreadsheet. It’s building the logic into a proper system — whether that’s your accounting software configured correctly, a purpose-built application, or an automated workflow that connects the tools you already use.

I’ve replaced spreadsheets with custom applications built on platforms like Retool and Supabase that do the same calculations — except they’re reliable, auditable, and anyone on the team can use them. The data posts directly to the accounting system with no manual re-entry.

If you’re nervous about what would happen if your key spreadsheet person left tomorrow — that’s your signal to build a real system.

If this sounds familiar, the issue usually isn’t the work — it’s how the system is built. And that doesn’t fix itself.
