How Retainage is Calculated on Invoices
The retainage amount withheld is usually based on the entire invoice, but it may also be based on specific invoice sections.
For example, you could bill the reimbursable and consultant expenses in full when the invoice is issued, but apply a 10% retainage to the remaining invoice sections until you complete the project satisfactorily.
On the Misc tab in Billing Terms, select any of the following invoice sections to which the retainage percentage will be applied: labor, consultants, expenses, fees, units, and/or add-ons.
Retainage Not Printing on Invoices
Check your Billing Group settings () if, on a previewed or printed invoice, the total invoice amount reflects the withheld retainage, but the amount of retainage does not print in the detail portion of the invoice (the detail does not add up to the total).
If you are printing the invoice using Billing Groups, and you have selected the Consolidate printing invoice option for a billing group and you have selected Project in the Print retainage by field for the billing group, retainage will not display on the invoice.
To fix this, change the Print retainage by option to Group.
