It has been a reliable processor. Payments arrive in the right account on time, fees are handled cleanly, and the dashboard makes it easy to track transactions. Better phone support is the one thing I’d add.ble payment processor Pros The deposits are reliable and land quickly in the correct bank account. Fees are debited on time and match what I expect, so reconciliation is simple. Once you learn the dashboard, the transaction accounting is clear and easy to use. Cons Customer service could be better. I’d like an 800 number where I can reach a live person for urgent issues. When something time-sensitive comes up with payments, waiting on email or chat isn’t ideal.

The set up process was very easy. I am very happy with Stax so far. Pros I like that they have customer service with people who actually help you. As opposed to square who's customer service is worse than non existent. Cons The fees are almost exactly the same as Square for us. Possibly slightly more than Square. So I didn't love that but the customer service is worth it. Switched from [Square Payments](https://www.capterra.com/p/170278/Square-Payments-Processing/) They have HORRENDOUS customer service.

It's not a turnkey solution like other providers but once you get things setup it's been pretty good Pros They have a good API which creates a tremendous amount of flexibility. The rates are very good. The capabilities are top notch. Cons Support can be hard to reach. The Dejavoo terminals have a very kludgy interface and the portals are confusing and need redesign.

Pros I like that they accept international cards, it makes it convenient and efficient for me to run my business. Cons What I like least about Stax is the monthly fees, as they are way too expensive and it’s not comparable to other merchant processors.

It allows our small business to manage billing efficiently, and stay on top of accounts on the fly. Automatic transfers into our bank account has been wonderful as well, as it takes a step out of the process and doesn't need to be verified manually. Pros Stax is incredibly simple to learn and use, and allows for incredibly quick and easy invoicing. Technical support is also next to none. Any issue I run into is easy to solve with a simple phone call. Cons I wish the app were as functional as the website for sending new invoices. Creating a new invoice to send a customer is a piece of functionality that would be nice to have outside of the website, as the Stax app seems much more intuitive on a phone.

Transferring over was clean and simple. I feel more secure with Stax than I ever did with other platforms that can shut you down without warning. Stax's assistance in getting approved was great, and knowing I provided all that verification gives me confidence that I can rely on Stax for years to come. Pros It's clean and simple. It's not confusing to work with and the fees are much more manageable/understandable. I come from other payment processors that charge a lot in fees for little in return. Stax is pretty clear. Cons I think Stax does lag a little in being able to offer instant access to funds. I understand why they can't, but it's a big gap compared to other offerings. Switched from [Stripe Payments](https://www.capterra.com/p/123889/Stripe/) Stripe's fees were high, and they never offered any support during chargeback situations. I felt that they didn't help me navigate those problems, and just took my money away from me instantly every time. I didn't like that. I want a partner.
