Fattmerchant has been great!!

Fattmerchant has been great. My contacts there have been honest and trustworthy. After agreeing to sign on with Fattmerchant, I was sent an email going over all the details we had discussed. So there was no confusion over the details. Funds are in the bank the following day. These guys are so much better than their competitors.

Great rates that actually are what I was promised

My company has been taking credit/debit card payments for our online continuing education courses since 2003. We recently switched to FattMerchant because of their great "subscription" type rates, that are simple and easy to follow.

They say it's "against company policy." So they will accept the data files, ...

Lots of fees

I felt a peace of mind with the $99 no contract terms, but turns out it's all a lie!Beware this company. They claim a $99/monthly fee plus direct cost for transactions. This is only one of the many monthly fees. $29.xx performance analytics fee, $5 chargeback protection fee, any several others. I could give a complete list if they would allow me access to my billing statements.When you cancel, they will state they will continue to charge your account for 30 days per the contract. Instead, ...

"Life-Saver For Our Business"

What do you like best about Stax? Fattmerchant has been nothing short of spectacular for our business. We were originally turned on to them by connecting through our software partners. Fattmerchant had recently begun processing payments for them, and they came highly recommended for our us. The consultation process was very friendly and straightforward, and then we were able to setup and implement their payment processing extremely quickly. Now, we have access to tons more data in addition ...
