Start from the job, enter your prices, and print the invoice. It never changes stock.
About 2 min · Admins and managers (prices are money).

Open the work order
Press Create invoice and type who is being billed.
Enter your prices
The labor hours and each part used are copied across with no price. Enter your price on every line; the page tells you how many still have none.
Add the rest
Press Add a line for shop supplies or anything else, and set tax and freight. The total updates as you type.
Save and print
Press Save changes, then Print. To undo an invoice, void it with a reason; it is never deleted.
Tip: The work order's own costs never appear here. The prices are the ones you type.
