Product research tells you WHAT to buy. It doesn't solve HOW you're going to pay for it.
The most dangerous mistake new Amazon sellers make isn't picking the wrong product—it's underestimating the cash jump required to scale it:
📉 Software costs spike (e.g., Helium 10 retiring its $39 plan, pushing entry to $99+/mo).
📦 Purchase orders require 100% up-front cash 60–90 days before goods arrive.
⏳ Amazon payouts hold revenue in 14-day cycles, choking cash flow right when restocks are needed.
Before burning your budget on enterprise software suites, lock down your unit economics & working capital strategy.
