Your spreadsheet works fine. Until it doesn't. Here's what actually breaks it.

I've been operating multi-unit franchise locations for 20 years. For most of that time, a spreadsheet was my inventory system. And honestly? It worked fine. For a while.

Here's the thing nobody tells you about spreadsheets: they don't break all at once. They rot slowly.

First it's a column you stop updating because you're busy. Then it's a formula someone overwrote by accident and nobody noticed for three weeks. Then it's two locations using different formats and now you can't compare anything across stores. Then your best manager leaves and the new person opens the spreadsheet, stares at 47 tabs, and just guesses.

The problem isn't that spreadsheets are bad tools. The problem is they rely on the person who built them being the person who maintains them. The moment that chain breaks, the data breaks. And you don't notice until you're staring at a $400 over-order wondering how it happened.

What broke mine for good was a simple moment. I was 4 hours away from one of my stores, my manager called out sick, and nobody else knew how to read the spreadsheet well enough to place the order. I was placing a blind order from a parking lot. That's when I realized the system lived in a person, not in a process.

What I did instead wasn't fancy. I made the count structured. Same day, same way, every week. The count feeds the order. The order feeds the data. The data feeds the next decision. No more guessing from memory. No more "I think we have enough."

If you're hanging onto a spreadsheet that mostly works, I get it. I was there for 15 years. But ask yourself this: if your best count person quit tomorrow, could someone else walk in and place next week's order with confidence? If the answer is no, your system isn't a system. It's a person.

I built TrackItWeekly because nothing on the market fit how operators actually count. It replaces the spreadsheet with a structured weekly count that anyone can follow. Same process every time, no matter who's working. But whether you use a tool or just clean up your spreadsheet process, the principle is the same: the system has to survive the person.

What broke your spreadsheet? Or are you still in the "it works fine" phase?
