Auto invoice number and references
If you leave the reference field blank on an ACCPAY invoice then the invoice number is automatically generated using the defaults INV-00381 etc. But if you give a reference 'August 2020 travel charges' and leave the invoice number blank then the API copies the reference and makes the invoice number 'August 2020 travel charges'. I want auto-generated invoice numbers but to be able to give an independent reference.
