“I just spent $4K restocking items I thought were selling well. Turns out half of them have been sitting for 3 months. I literally have no way to tell what’s actually profitable.”
“My spreadsheet is 47 tabs deep and I still can’t answer a simple question: which products should I buy more of? I’m running a business on vibes at this point.”
“Sold 200 units last month and somehow made less profit than the month before. I have no idea where the margin is leaking. Flying completely blind.”
This is what stalled growth looks like.
Cash locked up in dead stock. No clear picture of which products actually turn a profit after fees, shipping, and returns — so you can't tell which ones to pour more money into.
You scale based on gut feeling because your spreadsheet can't tell you what's actually working. By the time you realize something isn't pulling its weight, you've already doubled down on it.
The problem isn't effort. It's visibility.
