Is it possible to generate consecutive receipt numbers automatically
Enable box with red circle in screenshot.
Next time please first solicit the guides https://www.manager.io/guides/7820 that state for example (emphasis added):
Referenceis optional and may be used for cheque numbers, bank confirmation numbers, or other internal sequences. If the box within the field is checked, Manager will number the transaction automatically. The program will search for the highest number among all existing receipts and add 1.
You can consider enabling it in Receipt form defaults (bottom of receipts tab page).
Thank you the information
