PO financing fees are charged as a percentage of the financed amount per 30-day period. This is different from annual percentage rates (APR) — you pay the fee for as long as the transaction is outstanding, measured in 30-day increments. Understanding this structure is essential for calculating the true cost of any given transaction and for deciding whether your margin on the order is sufficient to support the financing cost.
Typical PO financing rates range from 2% to 6% per 30 days. Domestic supplier transactions (where your supplier is in the United States) generally get lower rates — 2% to 3.5% per 30 days — because the supply chain risk is lower and shipping times are shorter. International supplier transactions, particularly those involving overseas manufacturing or long ocean freight timelines, tend to price at the higher end — 3% to 6% per 30 days — because the transaction cycle is longer and there are more points of failure.
Worked example — domestic transaction:
A wholesale food distributor receives a confirmed $300,000 purchase order from a regional grocery chain. The distributor's supplier cost is $210,000 (70% of the order value, representing a 30% gross margin). The PO funder agrees to pay 100% of the supplier cost — $210,000. The financing rate is 3% per 30 days. The transaction takes 45 days from funder payment to customer payment (15 days for production and delivery, 30 days customer payment terms).
Cost calculation: $210,000 x 3% = $6,300 for the first 30 days. For the remaining 15 days: $210,000 x 3% x (15/30) = $3,150. Total PO financing cost: $9,450.
The distributor's gross margin on the order before financing: $300,000 - $210,000 = $90,000. After PO financing cost: $90,000 - $9,450 = $80,550. That is still a strong result on a transaction the business could not have funded without outside capital.
Worked example — international transaction with longer cycle:
An apparel importer receives a $500,000 purchase order from a department store chain. Supplier cost (overseas manufacturer): $325,000. PO funder advances $325,000 at a rate of 4.5% per 30 days. The transaction takes 90 days from funding to customer payment (45 days manufacturing and ocean freight, 45 days customer payment terms).
Cost: $325,000 x 4.5% x 3 months = $43,875. Gross margin before financing: $175,000. Net after PO financing cost: $131,125. This is a significantly higher cost than the domestic example, which is why businesses with international supply chains need to ensure adequate gross margins before using PO financing.
