Square vs. Stax Feature Comparison
As mentioned above, the best way to decide if Square or Stax is the best solution for you is to understand their features and pick the tool that's best aligned with your company priorities. Here's the full breakdown of some of the most important features of each tool.
Square and Stax are tied when it comes to POS hardware solutions. Here’s why:
- Stax offers a wider variety of POS solutions and provides a free terminal or card reader as part of its lowest-tier subscription.
- Square has fewer options. However, those options are guaranteed to work together more cohesively via hardware kits, and its $0 tier subscription provides a free magstripe card reader.
In this instance, it comes down to whether your business values cost-effectiveness or flexibility more. Both product offerings have their merit in this category, so you really can’t go wrong picking either.
Stax currently has 15 different POS solutions on offer from five different manufacturers: Dejavoo, Clover, Ingenico, First Data, and Stax itself. These solutions include card readers, which can be attached to a mobile device; traditional payment stations; and pin pad card readers. The first card reader or terminal is free with any of Stax’s plans, but subsequent terminals or readers must be bought separately. If you need to replace a broken or worn-out card reader or terminal, Stax offers a Terminal Protection add-on feature to allow you to make unlimited swaps.
Meanwhile, Square only offers six hardware options, but they’re all Square products and can function together without much worry. In fact, Square offers a number of hardware kits to make purchases and setting up multiple POS solutions easier than ever. All Square plans, including the free tier, provide a Square Reader for magstripe cards. Though Square hardware is cost-effective, this is less flexible than Stax’s free hardware offering.
Square is the better choice when it comes to invoicing. Here’s why:
- Stax offers a number of interesting and useful features for invoicing, such as custom invoice template creation and automatic payment reminders.
- However, Square offers those same features at a lower price and also includes estimate-to-invoice auto-conversion.
With the Stax platform, you can create and send out custom digital invoices via text or email with ease. You can also schedule recurring payments, set automatic payment reminders, and seamlessly track payments and other financial data in real-time from either your desktop or mobile device. Invoicing comes as part of Stax’s lowest-tier subscription, meaning these features are available at no additional cost to you.
Through Square Invoices, customers can send an unlimited number of invoices, contracts, and estimates. Invoices can be sent via SMS or email or by sharing a link to the invoice. The service is free, but businesses that want to streamline these processes should consider a Square Invoices Plus subscription for $20 per month, which adds features like milestone-based pay schedules, custom invoice template creation, and estimate-to-invoice auto-conversion. While this feature is offered as an addition to Square’s credit card processing subscription, the total is still more affordable than Stax’s offering.
Square is the better option when it comes to fee visibility. Here’s why:
- Square provides its processing fees on its pricing page
- Stax does not do the same, nor does it show up anywhere else on their website.
Despite its claims of transparency, Stax isn’t very open with the cost of its processing fees. Even in an article published on Stax’s blog directly comparing Square's and Stax’s processing fees, the company did not provide the actual calculations for its fees compared to Square’s, only showing the results. Until Stax becomes more transparent in its processing fees, Square takes this category.
That said, it should be noted that Stax claims a 0% markup on processing fees, claiming to only make a profit off its monthly subscription fees.
Square is the better option when it comes to availability. Here’s why:
- Stax is only available in the U.S.
- Square is available in the U.S., Canada, Australia, Japan, the United Kingdom, the Republic of Ireland, France, and Spain.
There really is no contest for companies operating outside the United States. Stax is a wonderful solution for U.S. merchants, but everyone else will need to find a more international solution such as Square.
Square and Stax are both excellent credit card payment processing solutions. The reality is that the vast majority of merchants, especially those that work primarily out of the United States, would be happy with either option.
However, Square and Stax are each slightly better for different use cases. You should pick the tool that best fits what you and your business need to succeed.
