credit card processing solution for low volumes. Advice needed!

Hi!

I want to let users make purchases and pay by credit card in our NetSuite environment. I understand this requires a merchant account, and I have performed a successful integration with Adyen (using their bundle) to try this. Everything works.

However, for low volumes it seems either extremely expensive or impossible (Cybercom requires minimum 10 000 transaction/month and Adyen’s fixed costs are very high).

Do you have any advice on a solution I can use for much lower transaction volumes ( appr. 10-100 trans./month). Preferrably a payment provider that already has an out-of-the-box integration with NetSuite.

Any advice would be greatly apreciated!
