Did your lender set you up with any kind of A/R and inventory line at close? If so then they would be able to increase that line. Typically Amazon working capital is pretty expensive compared to bank debt. A line should always be put in place foe just such a situation. Even a small line at close can be increased based on growth. The issue is lien position. If you don't have a line at close, the WC assets will be tied to the SBA loan. If you have a line with 1st position on A/R and Inventory, you have more flexibility. If your lender did this at close you should be able to get an increase.
