Retainage Percentage and Period
If the invoice or return used retainage accounting, the program will display additional percentage and period retainage fields for each detail line.
The program will also display the Retainage tab to let you specify the exchange rate that you want to use for the multicurrency retainage on credit/debit notes.
If you uncheck the Retainage checkbox, the percentage and period retainage fields will disappear from the item detail section, and the Retainage tab will disappear.
You can check the retainage field for job-related transactions even if retainage was not used on the original transaction.
Note that retainage accounting applies only to job-related transactions, and is available only if you selected retainage accounting in the Accounts Payable program.
