Dear RedmineUP-Team,

It is important to us that invoice numbers are generated in sequential order based on the invoice date.
Since invoice numbers are generated when a invoice is created, there may currently be discrepancies if the drafts are not processed and sent in this order. Since several people in our company issue and send invoices, this currently requires a considerable amount of coordination.

We would like the invoice number to be generated optionally only when the invoice is sent and for drafts and quotes not to receive an invoice number.
This would allow any number of drafts to be created and as soon as an employee sets an invoice to “sent,” the next available invoice number would be determined.

Looking forward to your feedback.

Best Regards,
Marcel Küpper
