How can I control invoice/order numbering?
How can I use skipped invoice/order numbers?
Why are my invoice/order numbers skipping?
How do I keep the program from using an invoice number when I create a new order that I don’t want to save?
The program is designed to start your order/invoice numbering at whatever point, and then every time you add a new order, it will increment that number. The point is for it to get a new number, and the order really doesn't matter.
There is no functionality for reusing skipped numbers or anything like that. Whatever number is entered in the Current Work Order number box on the Order Numbering tab of the Company Setup screen (Misc/Setup pull-down > Company/Misc Info option > Order Numbering tab) the next order you enter will have an order number that is 1 higher, and so on.
