Available in Sage 50 Premium Accounting and higher.
If you selected Employee Rate, Activity Rate, or Override Rate as the billing type, then the billing amount is equal to the billing rate multiplied by the unit duration. If you selected Flat Fee as the billing type, then you can enter an amount in the Billing Amount field. The billing amount is used when applying time tickets to sales invoices.
Billing amounts must be zero or greater before you save time tickets. You cannot create a ticket with a negative billing amount.
Note: If you want to enter a credit item on a customer's sales invoice that is related to a Time ticket, you must manually enter a negative line item on the sales invoice or use the Credit Memo feature. The time ticket itself will not be adjusted.
