Reading the result

A late invoice costs more than the interest on borrowed cash.

Late payment can create three separate costs: financing the gap, losing the productive use of that cash, and spending staff or management time chasing the receivable. The Advanced model can also include expected default loss and outside collection fees.

Opportunity cost is an assumption, not a guaranteed lost profit. If you prefer a conservative estimate, set the opportunity return to zero and focus on financing and collection costs only.

Financing costThe carrying cost of funding the cash gap while the invoice remains unpaid.

Opportunity costAn estimate of the return the delayed cash could have produced elsewhere in the business.

Collection costStaff, management, legal and processing costs associated with getting paid.
