We've used Paymentech in the past but it took 8-10 business days to get payment
Now we use Wells Fargo via Authorize.net Gateway and get paid alot quicker.
When comparing various service providers, be sure to ask these questions:What is the quality and reliability of their processing service?
What is the provider's reputation and stability?
What is the responsiveness of their customer support team?
What are their service options?
Do they offer comprehensive fraud management capabilities?
Do they require long term contracts?
Good Luck with your new store.
