I'll admit that thinking about NWC pegs makes my head hurt. Situation is seller is an inventory based business that does quasi accrual accounting (cash based with YE adjustments).

Sales are retail credit card, so no A/R, just inventory as an asset.

A/P would be the only liability, but they are not tracking payables, just payments (again, cash based)

If we had A/P by month (and in transit inventory), calc would be pretty straightforward, but alas, here we are.

Anyone that has dealt with something similar, and can you share any sage advice on how best to navigate would be greatly appreciated.
