You can manually add interest to supplier payments in Supplier Payment Create. When you open the Supplier Payment–Allocate subscreen to select the invoice or stage to pay, you can specify interest in the TC Interest Amount field on the grid. The Amount Allocated field in the header is updated accordingly.

For non-staged payments, you specify an interest amount on the invoice line in Supplier Payment Selection Create.

You can apply interest to invoices with staged credit terms using two different approaches:

Supplier Payment Selection Create, No Interest Specified shows an outstanding supplier invoice for 80 USD that includes staged credit terms. The staged payment details are shown on the level 2 grid line for the invoice.

The interest amounts you enter at the staged level are rolled up to update the TC Payment Amount and TC Interest Amount fields at the invoice level, as shown in Supplier Payment Selection Create, Interest Entered at Stage Level.

You can also enter interest for an invoice with staged payments at the invoice line level, as opposed to the staged payment level, in Supplier Payment Selection Create. This example uses an invoice of 55 USD that must be paid in two stages.

On the invoice line, you enter a TC Interest Amount value of 5.50 USD. This value is rolled down to the staged payment level and automatically allocated against the first staged payment due.
