AP is effectively short-term, interest-free supplier credit. Stretching payment terms — Days Payable Outstanding (DPO) — frees up cash, but pushing too far damages supplier relationships and may forfeit early-payment discounts (e.g. 2/10 net 30 offers a 2% discount for paying within 10 days instead of 30).
The gap between DSO and DPO drives the cash conversion cycle: businesses that collect quickly and pay slowly self-finance growth.
DPO = (Accounts Payable ÷ COGS) × 365
A restaurant receives CHF 20,000 of food deliveries on net-30 terms; the amount is recorded as accounts payable until the supplier invoice is settled.
