We previously used carbon-copy invoices, which worked well because the customer kept a copy and we retained a signed copy for our records.
Since the recent invoice changes, and to reduce unnecessary paper waste, we've moved to using the web-based invoices, which print on a single A4 page. This has resolved the paper issue, but it's created a new challenge.
We still require a signed Proof of Delivery (POD) to be returned to the office for our records, while also leaving the customer with their invoice.
I'm a bit stuck on the best way to achieve this without printing duplicate invoices or creating extra paperwork.
Any ideas would be greatly appreciated!
