Optional Invoicing

Customers can choose weather they want to have an invoice or not

Producing invoice for individual users can be made optional.

Shop - Products list

choose the product you desire to buy

Shop - choose payment

select the payment method you want to use among the listed

Shop - Registration form with invoicing unflagged

in the registration form, if you don't care about getting an invoice for the current purchase, just leave the "request invoice for current purchase" unflagged, and you'll be left with only user name and password to fill in.

Shop - Registration form with invoicing flagged

in the registration form, if you want to get an invoice for the current purchase, just select the checkbox for it, and you'll be asked to fill in all the necessary data to produce your invoice.

Backend - Orders module

If a purchase is made without requiring in invoice for it, in the backend of the VirtualNewspaper, it will be shown as such. It will also not be visible in the Invoices module.

This saves time to:

all those people that don't need an invoice and would rather just fill in username and password and read their paper.
the editor that does not want to wast time producing invoices for people that don't want it

It reduces the volume of invoices produced by the editor, making it's job easier.
