I was looking to edit the invoice numbering system and found that there is not option to change.

The default numbering system zoho has is editable prefix and auto numbering suffix (Eg INV - 001).

It would be really helpful if they could provide a auto numbering prefix and editable suffix. (EG 001 -INV).

This is crucial because many use differnt format for invoicing and zoho has a fixed format. Also, we can't change the invoice format in between the financial year, we can change format only during start of the new FY. Change in format would be really helpfull.
