I hope I am placing my query at right place.
I am using Zen cart for last 1 year, (Still) I don't have payment getaway, customer placing an order and then making payment by cheque, DD etc. I have to cancel or delete some order because of non payment,
Now I have register for TAX and I have to submit all the invoices to them, Now problem starts
my invoice should be serially arranged, Zen cart giving Invoice number automatically to every order,
sold or dispatched orders have some cancel or deleted orders in between. so sold invoice are not serial some invoice
numbers are missing, I want to customize my Invoice layout and want Invoice number generated or given by admin if sale is completed by payment. and current Invoice ID show as order number.
I have searched the net and found a problem for Opencart is my solution, in opencart invoice number is granted or generated by admin, can this be done by Super order or PDFOC ?? or is there any module available for this problem ??
I did't find any solution for my problem, please help in this regard.
I am not a coder and running my site by myself with lots of coding and help from you and forum.

Thanks in advance.
