RE: Accepting Credit Cards through GP?
Hi,
Yes, in order to process credit card transactions within GP, you need a third party credit card processing product. Each of the CC add-ons for GP may handle transaction processing differently, and they may work with different credit card 'gateways', so you will want to shop around to ensure that the solution you choose meets your business requirements.
For instance, if you do recurring billing or large batches of transactions, not all CC software can accommodate such processes. Or if you have a large number of declined transactions, some of the CC packages cannot automatically rebill those declines. So you really want to work with your GP partner to evaluate the different options and ensure that you choose one that has the features you need.
I would make sure that the CC software you choose supports Tokenization, and that the gateway service you choose also supports Tokenization (and confirm the software works with that gateway). Tokenization makes PCI compliance much simpler.
A few CC packages for GP that I'm aware of:
Nodus Credit Card Advantage

Blue Moon Credit Card Payments

k-eCommerce Credit Card Extension (has some rough edges)

Let me know if that helps and if you have any additional questions.
