In Zervant, you can copy an existing invoice which is especially handy if you send the same invoice regularly to the same customer.
In order to create a copy of an invoice, please
1. Go to the invoice tab
2. Select the invoice you want to copy
3. Select >More in the upper-right corner
4. Select >Copy as new
The copied invoice will have the same customer details and the same items as the original invoice. However, you can still change the customer and add or delete items from the new invoice.
The invoice number will be created automatically and will be the next in the invoice number sequence.
