My previous invoicing solution (Harvest) allowed me to have different invoice number schemes for different projects. I could have invoices to customer ABC be auto numbered to ABC-YEAR-1   (increment by 1 on the next invoice).  Customer XYZ's invoices could be similarly numbered XYZ_YEAR-1. Since moving to Zoho Books, I've had to drop project specific invoice numbering schemes and inform my clients that my invoice numbering format has changed. But it would be nice if Zoho books could allow custom project specific invoice number schemes

Thanks
