We save $1,000's on fees with FattMerchant

5.0 5 years ago

Comments: Their support is great. I've had dozens of questions and they always get back to me. And they send your payments super fast. Great experience overall.

Pros:

Flat rate pricing! Oh man, this is a breath of fresh air. After using stripe and square to process payments we have absolutely loved the simplified pricing structure that Fattmerchant uses. Only paying interchange fees and a fixed monthly rate saves us $100's each month.

Cons:

The integrations are weak. We've had to build a few workarounds to get fattmerchant to work with our tech stack but it's been worth it.

The price is good but it has been a change for me now that they are getting more popular.

4.0 4 years ago

Comments: It started out as a pleasant surprise but the last year has not been as good. Their business is expanding at a serious pace and they are adding features for the price increases but I do not find value for me or my business in the new features.

Pros:

The costs are good and the billing is straightforward. The customer service has been very good but has been slipping the last few years. I referred about 4 other local businesses in my area to Fattmerchant over the years.

Cons:

The price keeps going up and I am a 4-month seasonal hospitality business that has been seriously affected by the pandemic. I also know that all prices go up, however, I was told in the beginning that I was in early for their company and my price would stay the same. Whether or not that was a sales tactic so I would give them a chance 5 years ago I do not know. I remembered that statement. A few months ago I got blindsighted with a big increase in my monthly cost. They are working on it but it is 3 months and it is still not resolved. It still is a low-cost merchant provider compared to others but I have a regional restaurant buying club alternative that has been begging me to give them a chance so I may because of this issue.

Dubious excuses to problems

2.0 3 months ago

Comments: They are fine until you have a problem. Do yourself a favor and ask around and do your due diligence before signing up. This way, when things go bad you can only blame yourself.

Pros:

On time banking. Sales people nice, but aren't they all?

Cons:

Customer service, sneaky price instability.

Easy to Use - Customer Service On Point

4.0 6 years ago

Comments: Being able to keep cards on file and charge them after my lawn services are complete is a lifesaver. It keeps me from having to bill each customer, or chase my money down from now on. Also, the way they charge you for accepting credit cards is extremely clear and one reason I went with them. The larger I get, the more affordable FattMerchant will be as well, since the main cost each month is the flat monthly fee that will never change for you once you sign-up with them.

Pros:

Fattmerchant is so easy to use, even to me who has never really used a credit card processor to speak of. The software hasn't been without flaw, but what I like is anytime an issue has come up I email the small team at FattMerchant and they get back to me quickly and work to fix the problem and then update me on their progress. Maybe someday when they get really big this won't be the case, but for right now I am really impressed with their response and customer service. I've already recommended this to one of my friends and will be recommending it more in the future. Plus they give incentives for recommending them, which is nice.

Cons:

I wish they had a way where I could send someone a form and not an invoice to collect a card number. I wouldn't even need to be able to see the entire number, but if it could just collect it to be charged in the future. Right now the only way I have to collect a card number is either have the customer pay the first invoice, or have them call me and collect it over the phone, which I don't like. This is really the only thing I wish they would find a solution for though.
