Calculate the two payment amounts

The full invoice is 1,000,000 with a 1.5% qualifying discount. Day-10 payment is 985,000, and day-45 payment is 1,000,000. The discount amount is 15,000.

Use the discounted amount as the modeled borrowing base

Identify omitted costs and constraints

The exercise assumes that exact amount is financed for exactly 35 days with no fee or additional effect. A real facility’s costs, day-count rule, availability and payment conditions may differ.

Avoid an automatic borrowing instruction

A positive arithmetic difference under the supplied assumptions is not a complete recommendation for a particular company. Use actual-horizon terms and constraints for the real decision.
