When I started freelancing 5 years ago, my accountant advised me to start with a large invoice number (eg: 20850) and increment for each new one :)

- eru 16y agoDecrementing from there would be more fun.
- thibaut_barrere 16y agoFun indeed! Unfortunately illegal in France afaik.
- mcculley 16y agoWhen I started consulting, I initially made the date part of the invoice number, e.g., 04100501 was the first invoice sent on October 5th of 2004. This sidestepped the problem of showing customers how many invoices I had already sent. But it did show them how many I sent that day, which was usually not many. I eventually switched to a sequential monotonic invoice numbering scheme for other reasons, mostly because it made it easier on the webapp I use for invoicing.
- InclinedPlane 16y agoyymmdd<seq-#> is monotonically increasing. Though you could also just combine the first 6 or so digits of unix time and tack on a sequence number to the end of that.
