As small business owner, I don't wish to effectively send a report (the invoice number) of how many invoices I have raised in the past month to my customers every month. I find it strange that I cannot have invoices numbered ACME-0001, ACME-0002 etc auto-incrementing for Acme, and CUSTB-0001 and so on for Customer B. I would like to move my businesses over to Kashflow, and will do if this is implemented.
