Hi Ryan,
In practice, a 2% 10 Days results in payments being received on or around the 10 days of the invoice date.

If the discounted payment is received and applied in 12 days (within Adagio Receivables), you have to manually adjust for the discount amount or backdate the payment (to let the system calculate the payment). Both of the options are ugly and inefficient, if as a rule you are still planning to give the discount on the payment of the open invoice if they are close to the 2% 10 Day terms.

A practical option to deal with slightly late payments is to show the terms as 2% 10 days but use the configuration options to change the discount period to be say 12 to 15 days. That way, the system calculates the discounted amount and you don't have to force the amount or backdate the payment date.

It can have negative implications if you are aging your AR statements by Due Date (by extending the due date), but again in practice we see that not many customers follow that aging by Due Date on their AR statements.

Best,
Brian
