currently quotes fall into the same number range as invoices. This makes it laborious to audit sales in your accounting package (in my case Xero) as you have to get the list of every invoice posted to Xero, look for missing invoice numbers and then go back and check in Neto as to why they are not in Xero. It would be much more transparent if the quotes had their own number range and when you converted it to an invoice, the reference on the invoice would simply default to the quote number so you maintain the link.
