accept payment method before print invoice
got a question for all you experts out there.
I have a custom pos i am working on and i have created invoices and now printing properly but would like to after creating the customer invoice, and when user clicks on save & print i would like:
- payment method ( cash, credit, check),etc to be entered with current bill total from invoice
- then payment to be added to print layout with balance for total on invoice.
I hope that makes sense. i would like to know the BEST way to achieve this while not screwing up my totals from invoice.
