Good evening...
If you haven't input anything yet, as far as sales invoices go, all you need to do is input your next invoice number in the 'auto' box, create the information, print and update it and then your next invoice / credit note with follow on numerically automatically without the need for you inputting the invoice number... You can practice this in 'practice' data... choose 'practice' instead of 'company data' when you first open sage...create a pretend invoice with the number you want to start sage with and then create another one not inputting any invoice number and see how it works... hope this helps...
