While an incorrect Sub bill can always be returned to a subcontractor to Edit, sometimes it is easier to simply Delete a billing and start over. To delete a subcontractor billing you:
Click on Accounting>Billing>Delete Sub billing to access the list of billings.
Locate the correct bill and select Delete.
NOTE: If you choose to Delete a bill that has later bills already submitted, these bills must all be deleted. Since each bill is based on the previous pay application, the calculations would be incorrect.
