Hi b-tech,
Firstly, please allow me to extend a warm welcome to the Community Forum!
I completely understand your concern with the current numbering system. It can certainly be confusing for both you and your clients when the invoice number mirrors the quote number. Not to worry. I've duly marked your file as affected and included your post in the raised ticket for enhancement. Thank you for your understanding and patience in this matter.
Feel free to post anytime you need further assistance.
Cheers,
Princess
