AS lots of us runs small bussiness understands that when you write invoices there cannot be such things like skipping on invoice numbers it has to be increased one after another not skipping any number.
By default probid invoice numbers are assigned to the auction id so if a user were selling auction id nr: 100001 it will be assigned to 100001 but what happens if user doesn't select paid features, and his auction are free from fees? and later another user selects paid features but his auction number is 100003 ?
Yes you thinking correct your invoice number will be skipped and instead of 100002 you will see 100003 invoice number and that is not correct it looks like you lost somwhere the invoice with number 100002.
This mod will solve it no matter the auction was invoiced or no, the invoice will be increasing allways in correct format. it applies for reverse auctions, wanted ads, signup fees and all other invoices on your probid website.
