Can this software handle manual payment methods? My store will need all items to have this method and all other payment methods need to be removed. Once the order is received and invoice is manually sent to the customer.
If so, can you point me in the right direction or to documentation to accomplish this?
Manual payment methods
Some customers don't want to pay for their orders using a credit card. These customers can still place their orders online if you set up a manual payment method. When your customers use a manual payment method, you can arrange to receive their payment outside your online checkout. After you receive the payment, you can then manually approve the order.
