I have watched it happen too many times to call it bad luck. A seller comes to me doing 40% gross margins, products that fly off the shelf, reviews stacking up. On paper they are crushing it. Then the supplier wire goes out, the prep invoice lands, the inbound placement fees hit, and three weeks before Amazon’s payout clears, they cannot afford to reorder the SKU that funds the whole business. Profitable on a spreadsheet, broke in the bank.
That gap is the single most common reason healthy Amazon brands stall, and almost nobody talks about the cheapest way to close it. Everyone wants to sell you a loan. So let me explain why the gap exists, why it got wider in 2026, and the lever most sellers never think to pull.
The 60-second version
Cash flow is not profit. Profit is an accounting number; cash flow is whether you can pay your next supplier invoice. Between selling a unit and having the money, Amazon holds a reserve and runs a disbursement cycle, and your cash was already locked in that inventory for 30 to 90 days before the sale. Growth makes it worse, because every reorder pulls more cash forward before the last batch has paid out. The usual fix is debt. The cheaper one is to defer a cost you control instead of borrowing against a timing problem.
The real order-to-bank timeline
The reason your cash feels tighter than your profit is the distance between a sale and the money landing. Amazon’s Delivery-Date-Based Reserve, known as DD+7 and effective around March 12, 2026, holds funds until roughly seven days after delivery, on top of the standard 14-day disbursement cycle and a few days of ACH. Stack that on the 30 to 90 days your cash is already tied up in inventory, and a profitable business can still run dry. Confirm the current reserve and payout terms in Seller Central.
Cash flow versus profit: profitable on paper, broke in the bank
You can be profitable on every ASIN and still stall, because the money is trapped in units in transit, units in FBA, and an Amazon reserve, all at the same time. This is the trap that kills otherwise-healthy brands, and it is why two sellers with identical margins can have completely different outcomes, one with breathing room, one one bad month from a stockout they cannot afford to prevent. The per-ASIN side of this is in true profit per ASIN.

The lever most sellers never pull
The standard answer is a working-capital loan: more debt against a timing problem. There is a cheaper lever, which is to defer the cost you actually control. PrepVia Profits lets eligible sellers defer prep payment up to 30 days, with no credit check, scored on real operational performance rather than a FICO number. Pushing the prep bill past your Amazon payout closes part of the gap without interest. Pair it with tighter restock timing so you are not over-buying inventory that traps cash, see Amazon FBA days of supply. It is one of the thirteen tools every Amazon seller should expect from a prep center.
Frequently Asked Questions
How long does Amazon take to pay FBA sellers?
Plan on the standard 14-day disbursement cycle plus a few days of ACH, and now the DD+7 reserve that holds funds until about seven days after delivery. End to end, the money from a sale can take a few weeks to become spendable. Confirm your account’s current terms in Seller Central.
What is Amazon’s DD+7 policy and how does it affect cash flow?
DD+7, the Delivery-Date-Based Reserve effective around March 12, 2026, holds disbursement until roughly seven days after the order is delivered. It lengthens the time between selling a unit and having the cash, which widens the gap you must fund from working capital.
How do I fund Amazon FBA inventory without taking a loan?
One way is to defer a cost you control instead of borrowing. Deferring prep payment, for example, pushes part of your outflow past your Amazon payout and closes the gap without interest. Combined with disciplined restock timing so you are not over-ordering, it reduces how much working capital the business needs in the first place.
Why am I profitable but always short on cash?
Because profit and cash flow are different. Your cash is locked in inventory in transit, inventory in FBA, and Amazon’s reserve, all before a sale converts to spendable money. A profitable business can still be short on cash when growth keeps pulling the next reorder forward faster than the last one pays out.
