Invoice autonumbering

I think I’ve put this somewhere before - but have just noticed that it’s still a problem, so will post again.
When creating invoices, I find that the numbering doesn’t increase sequentially - it seems to be adding 2 or 3 to the last invoice number each time.
I only noticed, because I’m now on a number much higher than the very small number of pieces of work that I’ve had this year…!

Hey @Jake_Rowe thanks for this - it would be useful to figure this out with you - is there a chance I could give you a call next week for 5-10 minutes to just understand what’s going on for you?

Sounds like a bug on the software to me.
