A brand told me they were stuck at $500K monthly
They wanted a marketing audit
I asked them one question: do you have inventory?
Silence
Their real problem wasn't marketing, they'd been out of stock 40% of the year and thought they had a demand problem
Every Amazon brand hits a growth ceiling and misdiagnoses the cause
Demand constraint means shoppers aren't buying, the listing isn't converting, ads aren't scaling, keywords aren't ranking
Capital constraint means you have demand but can't fund the inventory to serve it
Signs you have a demand constraint
➝ Sitting on 6+ months of FBA inventory
➝ ACoS climbing without conversion lift
➝ CTR dropping despite ad spend increases
➝ Organic keyword rank sliding month over month
➝ Return rate creeping up
Signs you have a capital constraint
➝ Stockouts multiple times per year
➝ Freight delays causing sales dips
➝ Cash tied up in inventory in transit
➝ Reorder cycles extending beyond ideal windows
➝ Missing peak windows because inventory arrived late
The tell most brands miss
If your PPC ACoS is stable and your reviews are strong but your revenue is flat, you don't have a demand problem
You have a capital problem masquerading as a demand problem
Fix the wrong one and you spend $30K on a listing refresh that doesn't move the needle because the actual bottleneck is inventory cash
Diagnose before you spend
Most growth problems on Amazon aren't marketing problems
