In my shop people have the option to pay using the invoice that is shipped with the product. We find this a user friendly way to pay and easy for the customers. No need to sign-up with PayPal, Way2Pay or any other payment method.
Unfortunately the downsite is that there are always people that DON'T pay.
Bummer...now we have to take the nessecary steps to get our money.
We would like to reduce the risk of loosing big amounts of money by not having the payment method available if the items in the shopping cart exceed say more than 50 euro's.
The problem is....I have no clue how :D
I have been looking at the payment module and the are all sorts of checks that look if the module is enabled, zone is right, etc, etc. I guess it must not be so difficult to get this extra check, but like I said...if have no clue how.
Would someone know how?
Thanks in advance.
