Hi eftl,
Thank you for your post and welcome here to the Community Forum. We apologize for not responding to you sooner. We regret that you are facing issues with linking purchase order to supplier invoice that includes original PO number and auto populates the invoice number from the pdf, and we are grateful for your effort for the steps you've provided.
In this matter, you may manually change the numbers for now, or you may convert order to bill, but before you press the record button, you would need to change the first character to a letter of the invoice number before recording it. Also, the steps you have provided are the only uncomplicated way you can change purchase order to an invoice and link the PDF to supplier invoice.
If you would like a change to be brought to this preference, I would encourage you to please take a moment to post on the AccountRight Ideas Exchange board for consideration. Thank you for your understanding and continued support.
Please don't hesitate to post again if you need help in the future.
