7 signs your business has outgrown Excel (and what to do about each one)

Between January and August 2026, real retail sales in Colombia grew 10.9%, while retail employment grew just 1.5%, according to the national statistics office DANE. More transactions with almost the same team is exactly when spreadsheets start to fail. If you track inventory in a spreadsheet today, this guide shows you how to do it properly and the 7 signs that it's time to move on.

You're selling more with the same team

Between January and August 2026, real retail sales in Colombia grew 10.9% compared with the same period of 2025. Over those same months, retail employment grew 1.5% (DANE, 2026). Much of the boost came from cars and motorcycles, but the pattern shows up in many businesses: more orders, more products and more invoices, handled by almost the same people.

That growth is good news until it reaches the spreadsheet. A spreadsheet works very well when one person uses it, for one business and one sales channel. When volume goes up and the team doesn't, every movement typed in by hand becomes a place where the numbers can stop adding up.

If you track inventory in Excel today, do it this way

Before you think about switching systems, get what you have in order. A well-built spreadsheet inventory lasts much longer than an improvised one:

If you do all of this and still recognize several of the following signs, the problem is no longer how you use the spreadsheet: your business has grown bigger than it.

The 7 signs

If you recognize one or two signs, you can still get the spreadsheet in order. If you recognize four or more, the cost of staying put rises every month, because it grows with your volume.

When it no longer fits

A custom system doesn't have to change the way you work: it has to remove the manual steps. At Salonika, a Greek restaurant with two locations in Bogotá, every supplier invoice enters inventory with a photo: AI reads the supplier, items and prices in 10 to 30 seconds and the team confirms. At Expogreens, a foliage exporter, inventory is tracked by variety and stem length, a detail that turns into a tangle of columns in a generic spreadsheet.

At Tom Studio we build that kind of system around the way your business already works, not around a template. Before you pay anything, we show you a free working prototype, with no commitment, using your own data.
