Amazon recently announced changes to how they handle advertising payments, and then backed off the original April 15 deadline. But the change is still coming — now set for August 1.

Here’s what matters: Amazon is moving to a DD+7 disbursement model for advertising charges, meaning ad costs will be deducted from your account seven days after the disbursement period closes. Combined with fuel surcharges and the loss of ad float that many sellers were using as working capital, this change will tighten cash flow for a significant portion of Amazon sellers.

The practical response: do a 13-week cash forecast now, before August. Map out how the change affects your weekly cash position. If you were relying on ad float as informal working capital, you need to replace that buffer before the change takes effect.

This isn’t a crisis — it’s a planning problem. And planning problems are solvable when you see them coming.
