Business Owner

Their helpline is always open and has been super supportive in getting my questions answered. Payments are processed quickly and my clients have found the system easy to use and invoices were helpful.

They keep taking funds out of my account despite their associate sending me an email stating that my account is closed. Total liars and so dishonest.

I see my money transfers quickly and I love not having to deal with the high percentages taken from my profit like other processors.

Love the ease of use, very intuitive and operational very friendly. Also, less expensive than our previous provider.

Owner

The staff is very helpful with the onboarding process, and the sales representatives are delightful to work with.

I love how easy and understanding it is to use Stax and how the recurring billing is set up. I will recommend this company to everyone I know.

Fattmerchant was a lifesaver in getting our business set up. We talked to many companies in this process who exhausted us by their lack of customer service skills or willingness to help effectively.

Stay away from this unethical business. We are so sorry we did business with them.

Practice Manager

The system is simple to navigate and easy to learn. Super user friendly, and whenever a issue arises, their support staff handle it quickly and tactfully.

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.

Customer service is horrible. For example I called twice today to speak with a rep about issues.

Manager

They always deny issues are their fault. Always some other company.

President

So far everything has been GREAT. Saving more money per month than I could have imagined when I first was looking for a new processor of CCs.

Provider

The terminal seems like it will be very easy to use. Sensitive content hidden] has made my learning curve less steep with getting the system integrated.

Goto a company that will treat you right and really want to earn your business, which Stax doesn't try to earn, its almost like expected.

Uncaring, incompetent customer service; high costs; stealthy increases in costs.

Chief Operating Officer

Software is straightforward and they offered competitive rates.

We have been with Stax for ~8 years and it's been good. My only complaint is they have not updated system to integrate with auto matching payments to QB in 8 years.

Vice President

This product is a great useful partner for my business, we deliver some of our marketing materials to our loyal customers with this. It's easy, quick, and professional.

Online retail wholesaler

I love that it's very easy to use at the register, and you can see how many points you have earned from previous purchases. Also, very easy to implement your rewards.

Founder

The most awesome feature I love about Debitoor is the option to import my business account so that I can go through it and use the incoming and outgoing payments as a todo list.

Law Student

This software encouraged me to continue to come back to get rewards, the rewards seemed like a bonus.

Customer Service Specialist 

The only complaint that I currently have is the limited availability in my area.

Barista 

Its super easy to use and understand and customer service is very helpful and knowledgeable.

Owner 

Everything the worst company ever I have used disgusting customer service.

Personal Trainer 

Amazing - would definitely recommend for all small and medium businesses.

team manager

The best thing about sumup is that provides pos with low cost and high quality. And accept several many payment methods like google and apple pay.

Our experience has been great with Fivestar. The customer service is top notch.

Often it works but sometime it's so long to do a payment with a client, loading, disconnection, error, no connection... and you don"t know why and when it will arriv.

Insurance Agent

I love how it send me my rewards and keeps them on point. I am able to search locations near me very quickly.

Retiree

Crossroads is awesome for everyone. Use of their system is so easy and rapid.

Bosd

Great Hud easy to use and all together great service.

The fact that one can be rewarded just for visiting a store or restaurant or any other place of business for that matter through five stars integration is always beneficial.

Freelance Web Developer

Debitoor sadly does not provide nearly enough features in the reporting departement.
