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. > > Being technical, I was able to build what I needed. I built my own portal to create the reports that I needed. It's not a turnkey solution like other providers but once you get things setup it's been pretty good ----- ### "Sign up for Stax and you will save a lot of money. Great service too\!" — 5.0/5 > **Rod** | *23 June 2026* | Automotive | Recommendation rating: 10.0/10 > > **Pros**: Very competitive transactions rates. Easy account setup. Works well. Integrates easily with other tools. > > **Cons**: There is very little that I can say negative about Stax. The only thing I can think of is that the account setup paperwork has become less complete recently. > > We are very happy working with Stax and plan to continue for a long time. The team has been very helpful even with some complicated circumstances for account setup. ----- ### "Lots of good, some meh" — 3.0/5 > **LESLEY** | *27 April 2026* | Health, Wellness & Fitness | Recommendation rating: 7.0/10 > > **Pros**: I picked Stax because Square was increasing its prices, and I wanted to avoid passing more costs on to my customers. > > **Cons**: It takes to long for yesterdays charges to make it to my bank account. Using Square, if it was charged by 8pm, it was deposited very early the next morning. The dashboard on the mobile app is not as user friendly or capable as I would like in checking daily, weekly charges. New payments using store credit cards is time consuming and cumbersome. > > Over all I am pleased with the pricing, but it is less convenient than Square in many way. Customer service has been helpful and responds in a timely fashion. ----- ### "Simple Setup and Hassle-Free Processing" — 5.0/5 > **Christina** | *23 June 2026* | Wholesale | Recommendation rating: 3.0/10 > > **Pros**: My experience with Stax has been excellent. The onboarding process was straightforward, payment processing has been smooth and reliable, and I especially appreciate that deposits are transferred automatically. Not having to manage manual transfers has made payment management much more efficient. > > **Cons**: While my overall experience with Stax has been positive, one drawback is that there can be a learning curve when navigating some of the reporting and account management features. Additionally, certain fees and pricing structures may take time to fully understand compared to simpler flat-rate processors. However, the ease of processing payments and automatic fund transfers have outweighed these challenges for my business. > > My overall experience with Stax has been very positive. The onboarding process was simple and straightforward, making it easy to get started. Payment processing has been reliable and efficient, and I especially appreciate the automatic fund transfers, which eliminate the need for manual deposits and save time. The platform has helped streamline payment management for my business, and the support and ease of use have made the transition smooth. Overall, Stax has been a convenient and effective payment processing solution. ----- ### "Good value and easy to use" — 4.0/5 > **Viren** | *23 June 2026* | Construction | Recommendation rating: 6.0/10 > > **Pros**: Easy to use, easy to share payment links. Fees are reasonable and I like the breakdown provided for each type of charge > > **Cons**: UI could use some improvement. I'd like to see a cleaner invoice page that we can share with customers. Right now the existing page feels dated and looks a bit too technical. ----- Page: 1 / 7\ Next: [Next page](https://www.softwareadvice.co.uk/software/390708/stax?page=2) ## Links - [View on SoftwareAdvice](https://www.softwareadvice.co.uk/software/390708/stax) ## This page is available in the following languages | Locale | URL | | en | | | en-AU | | | en-GB | | | en-IE | | | en-NZ | | ----- ## Structured Data
