I deleted a few invoices. (I had mixed up English and Dutch). So I have a gap of 4 digits in my invoice sequence. In the learning center, I read that I can adjust the numbering in settings / sales invoices. I choose other number for next invoice and press edit. I have tried this twice now, but the numbering just continues. (So now I have a gap of 6 digits). It does not take into account the sequence number I have chosen. I would appreciate some help. Can anyone offer any advice?
