Writing up or writing down an invoice enables you to have a fixed amount for labor and/or expenses, while still maintaining the hours, a rate per hour, and individual expense amounts.
After creating the invoice, put a check next to “Labor Total” or/and “Expenses Total.”
Put in the desired amount for the total(s).
Click the “Save” button. You will then see the original amounts are under a new column called “WIP” and the adjusted amounts under a column called “Billable.” However, the client will only see the “Billable” column.
It’s recommended that you edit the invoice template to not show the Rate column.
Note* The way the adjustment works is by writing down the Rate of the entry billed so the hours are not effected.
