Stax vs. Square

Stax vs. Square Highlights

Stax and Square help businesses accept credit card payments as well as digital payment methods like mobile wallets and ACH (direct drafts from customer bank accounts). Both vendors provide payment processing hardware, including card readers and POS systems, and integrate with various software applications. However, their distinct differences may make one platform a better solution for your company’s sales needs than the other.

Who Is Stax For? 

Stax is ideal for established and high-processing-volume businesses because of its low wholesale processing rates and all-inclusive software features. We like that it provides transparent pricing and a slew of features that make payment processing easy and accessible for businesses. We were impressed that it only charges a small per-transaction fee beyond the established interchange rates credit card companies charge. Stax also provides an excellent mobile app for iOS and Android that allows for in-person, online, and over-the-phone payment processing. Read our in-depth Stax Payments review to learn more about this vendor’s features and capabilities.

Who Is Square For? 

Square’s feature-full free subscription plan makes it ideally suited to low-volume or seasonal businesses. We were impressed by the functionality and value of Square’s free tier. Higher-level paid tiers add additional capabilities for growing and higher-volume businesses. We also liked Square’s functional and attractive POS hardware, which makes the platform an excellent choice for brick-and-mortar retailers and restaurants. It’s also ideal for companies that want one software solution to manage their business and businesses that use recurring billing or scheduled payments for memberships or subscriptions.

Stax vs. Square Service Comparisons

Here’s a closer look at each provider’s services and how they stack up against each other. 

Plans and Pricing

Stax

Stax offers two plans that depend on your processing volume. Both plans grant access to the platform’s full suite of features. If your processing volume is more than $500,000, contact the company for custom pricing. 

Each plan involves a monthly fee, but there’s zero markup on the interchange-plus processing rate — a highly unusual practice in the industry that impressed us.

Optional add-ons include ACH processing, a one-click shopping cart, digital gift cards, next-day funding and more. Note that the vendor imposes a $25 chargeback fee for disputed transactions. 

Square

We were impressed that Square’s basic plan has no monthly fee. Higher-level paid tiers add additional functionality. We also loved that Square doesn’t impose chargeback fees — a rarity in the industry.

Pricing is as follows (prices for higher-level plans reflect annual billing; you’ll pay more for monthly billing):

Additionally, Square offers add-ons that can help your business run more smoothly: 

• Email marketing add-on: Starting at $15 monthly, this add-on allows you to send unlimited emails, automate email collection, redeem coupons, automate email marketing campaigns,and more.
• Payroll add-on: At $35 plus $6 per person per month, this option gives you unlimited monthly pay runs for employees and contractors.
• Text message marketing add-on: At $10 per month plus messaging rates, you can automate text message marketing campaigns and add images.
• Loyalty program: Square can help you build a customer loyalty program. Rates start at $45 for 0-500 loyalty visits.

Payment Processing

Stax

• Multiple payment types accepted: In regard to credit card processing and digital payment processing, Stax allows you to accept all major credit and debit cards (swipe, dip and tap), Apple Pay, Google Pay, PayPal, Venmo, Pay Later and more. ACH processing is available as an add-on.
• Multiple payment methods: Accept payments online, in person and via text, invoice, hosted payment pages and more.
• Low processing rates: Stax processes a wide variety of payments at an unprecedented low processing rate. It’s the only payment processor we reviewed that passes along wholesale interchange rates to its merchants with no markup.
• Quick payouts: Stax’s quick payouts are another benefit. Many other processors take one to three business days to transfer your money into your bank account. However, with Stax, your money is deposited as soon as the following business day. If you need access to your money immediately, you can get an instant transfer for an additional fee.

Square

• Multiple payment types accepted: In addition to major credit and debit cards, Square allows you to accept Apple Pay, Google Pay, Samsung Pay, Cash App and ACH for invoices.
• Multiple payment methods: Like Stax, Square allows merchants to accept payments in various ways, such as via an e-commerce payment page, invoicing, recurring payments, hosted payment pages, virtual terminals and in-person with readers and point-of-sale (POS) systems.
• Payouts: You can either keep your sales revenue in your Square Checking account or transfer it to another bank account within one business day (or immediately for an additional fee).

Security

Stax

• PCI compliance: Stax is a Level 1 PCI Service Provider. While Stax is PCI compliant, as the merchant, you are responsible for PCI compliance on your end. Stax requires its merchants to complete and submit a PCI compliance self-assessment questionnaire annually so it stays top of mind. While Stax does not have its own proprietary hardware, the equipment it sells and is compatible with is PCI- and EMV-compliant.
• E-commerce security: If you have an e-commerce site, you can add a secure payment system. PCI-compliant software encrypts and tokenizes cardholder information so that it’s difficult for would-be thieves to intercept and use. This system cuts down on credit card fraud and chargebacks.

Square

• PCI compliance: Square provides end-to-end encryption of customers’ payment information, helping ensure PCI compliance.
• Fraud prevention: Square also uses machine learning models to identify and examine potentially fraudulent transactions. 

Software

Stax

Stax provides customers with the same features regardless of processing volume. 

• Software features: Stax’s software features include a dashboard, analytics, digital invoicing (which is frequently an additional charge with other processors), Text2Pay mobile payments, online payment capabilities, recurring invoicing, scheduled payments (also usually an upcharge from other companies), automatic updates of stored cards, and one-click shopping cart setup with catalog management.
• Interface and reports: Stax’s dashboard interface is easy to use; its reports provide vital information to help you make better business decisions.
• Paid add-ons: Stax charges for add-on services like digital gift cards, custom-branded invoices, digital receipts and website payments, ACH processing and terminal protection.

Square

Square’s intuitive software interface has modules that can help you manage your entire business.

• Financial: The financial module accepts customer payments, creates invoices, manages payroll, and tracks financial metrics.
• Marketing: The marketing module helps you with email and text marketing and gives you analytics to track and tweak your campaigns.
• Square Team Management: Square Team Management has time tracking, tip pooling, sales commission management and task management.
• Customer experience tools: Tools like Square Loyalty, Appointment Scheduling and Customer Directory help you improve your customer experience.
• E-commerce tools: For e-commerce, you may need a developer to integrate Square with your website. If you don’t have a developer or don’t want to spend the money, you can use Square Checkout to send customers to a Square-hosted payment page.

Customer Service

Stax

Generally, customers rave about Stax’s customer support. 

• Support channels: Stax provides customer service by phone, fax, email or online with its Knowledge Base. Customer service hours across all channels are 8:30 a.m. to 5:30 p.m. ET.
• Payment Depot transition: In July 2023, Payment Depot’s customers became Stax customers. For some, the transition was not as clearly communicated as they might have liked.
• Lacks digital support channels: We were disappointed that Stax doesn’t offer customer support via live chat or social media. 

Square

Our research revealed that Square’s customer service record is mixed. 

• Support channels: Square supports its merchants by phone (Monday through Friday, 6 a.m. to 6 p.m. PT), email, live chat and social media. It also has help available online in its Support Center and on YouTube. We like that customers can use live customer service chat via the Square POS app, which can be convenient.
• Supports only active customers: Square only provides customer support to active customers, so former customers can be left stranded if there is an issue closing their accounts.
