Hi In Croatia we have a condition in billing. A non formal invoice must be sent before official one. That happens when customer order something and then non obligation proforma invoice is sent. It happens due to because official invoice is required to be payed on tax even if it not charged /payed by customer. Is there option in WHMCS for such invoice.? Any module? I understand whmcs have a proforma invoice but that is just numbering. I need feature as such described. In English is called proforma invoice as I know. Any help?

Hi everyone
