You did everything right. Solid product, decent reviews, PPC dialed in - and then your best-seller sat "Out of Stock" for six days during your busiest week. Ranking dropped. Buy Box gone. And by the time inventory landed, a competitor had taken your spot.
Here's the part most sellers don't say out loud: it's not that you don't understand your business. It's that inventory planning was never actually supposed to be your job. You're running a brand — sourcing, listings, ads, customer experience. Nobody handed you a manual on reorder points, lead time variance, or how Amazon's storage limits shift with your IPI score. So you're left doing it in a spreadsheet, on instinct, hoping the numbers hold.
And honestly - that's not fair. A seller with a genuinely good product shouldn't lose sales and margin because of a supply chain gap they were never trained to manage.
We've seen this exact pattern across dozens of Amazon accounts we manage - from single-SKU brands to catalogs running 200+ ASINs. The businesses that actually scale aren't always the ones with the best product. They're the ones who never run out of what's selling, and never tie up cash in what isn't.
That's the entire job we do:
We start with your real numbers - sales velocity, seasonality, actual lead times from your suppliers. No guessing.
We build a SKU-level reorder calendar, so you know the exact date and quantity to order, weeks before you'd ever risk a stockout.
We track your IPI score and sell-through rate every week and adjust the plan as demand moves - so Q4 doesn't blindside you with a restock limit cut.
Left unmanaged, this usually goes one of two ways: thousands of dollars sitting in inventory that isn't moving, or months of ranking work erased in a single stockout you didn't see coming until it was too late.
What we're aiming for instead is simple - your top sellers stay in stock, your storage costs actually go down because you stop overordering, and your IPI score stays healthy enough that Amazon never restricts how much you can send in.
