Best Square Competitors and Alternatives in 2026

Stripe is a payment processor designed for online-first merchants and developers. Among the Square competitors in this guide, it stands out for its customizable payment infrastructure.

I would choose Stripe over Square for a business building a custom checkout, subscription service, or marketplace. Stripe Terminal can support in-person payments, but you still need the software and inventory tools to run a retail store.

For a retailer that simply wants to replace Square’s register, Stripe is usually a less direct replacement than Shopify POS or Lightspeed.

Stripe vs Square

• Stripe is stronger for businesses that need customizable checkout pages and advanced online payments. Square is easier to set up for retailers that want a simple POS with built-in hardware and minimal configuration.
• Stripe offers separate products for billing, invoicing, identity verification, and other payment functions. Include those charges when comparing its total cost with Square.

Who should use Stripe

• Online-first businesses that need custom checkout flows, subscriptions, or API-based payment tools
• SaaS companies, marketplaces, and ecommerce businesses that need advanced online payment workflows
• Businesses that want to add in-person payments but do not need a full built-in POS system

• Standard Payments subscription: No monthly subscription for standard pay-as-you-go processing
• Domestic online card payments: 2.9% + 30 cents
• Card-present payments: 2.7% + 5 cents
• Terminal reader examples: Reader M2 is $59; Reader S700 and S710 are $299 each
• Additional costs: Billing, Invoicing, optional Terminal services, development, and third-party software can add charges

Stripe Billing’s pay-as-you-go fee is 0.7% of Billing volume. Its one-time invoicing products have separate pricing, so I would not treat subscriptions or invoicing as included in the standard processing rate.

• Developer-first payment infrastructure
• Stripe Terminal for in-person sales
• Customizable in-app and hosted checkouts
• Separate tools for subscriptions, invoicing, fraud prevention, and identity verification
• Payout options that depend on account eligibility and country

Stripe user reviews are mostly positive for checkout customization, developer tools, reporting, and integrations. Common complaints mention setup time, account holds, and a steeper learning curve than simpler POS systems like Square.

Helcim is a payment processor and POS provider built around transparent interchange-plus pricing and business tools like invoicing and recurring billing.

I would shortlist Helcim when processing costs are the main reason for leaving Square. Its published markup makes it easier to see what the processor charges above interchange and network fees.

However, I would compare actual statements before recommending a switch. Interchange-plus pricing can be cheaper, but the result depends on the cards your customers use and how they pay.

Helcim vs Square

• Square wins on simplicity and ecosystem. It is easier to set up, has broader add-ons or integrations, and a wider hardware selection.
• Helcim is worth comparing for transparent processing markups and businesses that need invoicing or a virtual terminal without a monthly software subscription.

Get a more in-depth comparison of Helcim vs Square in our guide.

Who should use Helcim

• Established retailers, service businesses, and B2B merchants with steady monthly sales
• Businesses willing to compare statement-level processing costs
• Merchants that prioritize payments and invoicing over advanced retail inventory tools

• Monthly POS account fee: $0
• In-person markup for up to $50,000 in monthly card volume: Interchange and network charges plus 0.40% + 8 cents
• Keyed and online markup at that tier: Interchange and network charges plus 0.50% + 25 cents
• Higher-volume tiers: Lower published markups apply as qualifying volume increases
• Hardware: $199 for the Card Reader; $349 for the Smart Terminal
• Recurring payments: An additional 0.4% per applicable recurring transaction
• Tap to Pay on iPhone: An additional 10 cents per approved transaction

The markup is only part of the transaction cost. Add the underlying interchange and network charges when comparing Helcim with a flat-rate provider.

• Free mobile payment app and POS
• Interchange-plus pricing with automatic volume discounts
• Invoicing, hosted payment pages, and a virtual terminal
• Recurring billing and subscription management
• JavaScript API for secure, embedded online payments

Helcim user reviews are mostly positive for transparent pricing, helpful customer support, and easy-to-use payment tools. Common complaints mention longer onboarding, account approval requirements, or occasional holds tied to underwriting.

Lightspeed is a cloud-based POS built for deeper inventory control, advanced reporting, and multi-location management. Among Square competitors, it stands out for businesses with large catalogs or complex inventory structures.

I would consider Lightspeed when purchasing, supplier records, product variants, and stock management create more work than the retailer can comfortably handle in Square. A catalog of 300 SKUs alone would not justify switching; the daily inventory tasks matter more than the item count.

Its current X-Series pricing page lists inventory management, purchase orders, and supplier catalog tools. Feature availability varies by plan, so I would have the sales team demonstrate the exact workflow before signing.

Lightspeed vs Square

• Square wins on simplicity and affordability. You get free POS software, straightforward pricing, and a quick and easy setup.
• Lightspeed wins on inventory depth and retail scalability. You get advanced product management, multi-location tools, and detailed reporting that larger retailers often require.

Who should use Lightspeed

• Retailers with large product catalogs, variants, or advanced inventory needs
• Multi-location stores that need centralized inventory control and reporting
• Specialty retailers, apparel stores, and growing businesses that have outgrown Square’s inventory tools

• Retail X-Series annual-billing starting prices: Basic at $89/month, Core at $149/month, and Plus at $289/month
• Additional locations and registers: Obtain a complete quote
• In-person processing: Its dedicated US X-Series payments page lists 2.6% + 10 cents; confirm the contracted rate
• Hardware and implementation: Quote-dependent

• Product variants, purchasing, and inventory management
• Built-in ecommerce options
• Sales, staff, and inventory reporting, with plan-dependent depth
• Supplier catalog and ordering connections
• Onboarding and support options that should be confirmed in the agreement

Lightspeed user reviews are mostly positive for inventory management, product catalog tools, and unified retail and ecommerce selling. Common complaints mention pricing, setup time, and a steeper learning curve than simpler POS systems like Square.

Shopify is first and foremost an ecommerce platform, but its POS tools make it a strong Square alternative for businesses that sell both online and in person.

I would choose Shopify POS when a retailer wants its website, store inventory, customer records, and orders managed within Shopify. That is especially useful for a business already using Shopify online.

For a retailer starting from Square, I would compare the full Shopify subscription and POS Pro costs against the work saved by moving both channels into one system.

Shopify vs Square

• Square wins on simplicity and affordability. It offers free POS software, straightforward pricing, and quick setup for small businesses.
• Shopify wins on ecommerce depth and multichannel selling. It gives online-first retailers stronger website, checkout, shipping, and social selling tools than Square.

Who should use Shopify

• Ecommerce-first businesses that also want to sell in person
• Retailers already using Shopify for their online store
• Businesses that want inventory, checkout, shipping, and POS tools managed in one system

• Basic: $29/month billed annually or $39 with monthly billing
• Grow: $79/month billed annually
• Advanced: $299/month billed annually
• Basic in-person selling: Included with paid plans
• POS Pro: An additional $89/month per location with annual billing
• Basic in-person processing with Shopify Payments: 2.6% + 10 cents
• Hardware example: Tap & Chip reader from $49

Shopify does not have a free ecommerce plan. Its Starter offering is a separate, limited selling option and should not be used as the price benchmark for a staffed, two-store POS setup.

• Ecommerce platform with social selling and online store builder
• Built-in marketing and ecommerce automations
• Shared product, customer, and order records across channels
• POS Pro inventory, staff permissions, and retail reporting
• Live chat support; other support options depend on the plan

Basic does not include additional Shopify admin users. POS-only employees are treated separately and can access locations subscribed to POS Pro. That distinction matters when budgeting for store staff and back-office access.

Shopify user reviews are mostly positive for its easy setup, user-friendly POS app, synced product catalog, and real-time inventory tracking. Users especially like that Shopify POS connects directly with an existing Shopify store, making it easier to manage ecommerce and in-person sales from one system.

Toast is a POS platform built specifically for restaurants.

I would choose Toast over Square when the restaurant needs a more detailed service and kitchen setup, such as coordinated tableside ordering, kitchen displays, and multiple ordering channels. I would price the required modules together rather than assume the entry plan includes every restaurant feature.

Toast vs Square

• Toast provides deeper restaurant management tools such as kitchen displays, table management, and integrated online ordering.
• Square is often easier to start with for cafés, food trucks, and smaller restaurants. Its paid restaurant features are also worth checking before replacing the system.

Who should use Toast

• Full-service restaurants, bars, and growing food businesses
• Restaurants that need table management, kitchen display systems, and online ordering
• Food service businesses managing dine-in, takeout, delivery, and staff from one platform

• Restaurant Starter Kit: From $0/month for eligible configurations
• Restaurant Point of Sale: From $69/month
• Build Your Own: Custom pricing
• Processing, hardware, installation, and add-ons: Confirm in the quote

The Starter Kit uses pay-as-you-go processing. Lower upfront costs can come with higher transaction charges, so compare the complete annual cost with a paid-software offer.

• Kitchen display system integrated with digital and online ordering
• Advanced inventory management and recipe costing with xtraCHEF
• Workforce management options for timekeeping, payroll, and HR
• Restaurant operations tools including table management and catering support
• Add-ons for loyalty, marketing, and gift cards

Toast user reviews are mostly positive for its restaurant-specific POS tools, tableside ordering, kitchen display features, and online ordering options. Users especially like that Toast is built for food service workflows, though some mention pricing, contract terms, or support responsiveness as drawbacks.

Clover combines proprietary POS hardware with software plans and apps for different business types. I would consider it when a merchant wants a specific countertop or handheld setup and is willing to compare offers from different sellers.

The choice happens before purchase. Do not assume you can buy any Clover device, connect an existing merchant account, or move the device to another processing provider later. Ask the seller to confirm those terms in writing.

Clover vs Square

• Clover offers countertop and handheld equipment with industry-specific software and app options. Square is generally easier to compare and purchase directly.
• Clover offers offline payment settings on supported devices, but limits and merchant risk must be reviewed. Square’s offline rules also depend on the equipment; a blanket seven-day-versus-24-hour comparison is misleading.
• Compare support, cancellation terms, and equipment commitments for the actual seller rather than assuming every Clover offer is the same.

Who should use Clover

• Businesses that want more POS hardware options than Square offers
• Retail and service businesses that want industry-specific POS setups
• Merchants that want to compare seller offers before committing

• Software and hardware: Depend on the selected system, plan, seller, and purchase arrangement
• Processing: Obtain the rate for your business type and payment methods
• Other costs: Include app subscriptions, equipment payments, and contract obligations

Clover’s advertised hardware payment is not necessarily the software subscription. For example, its retail page lists both equipment purchase and subscription arrangements. Compare the full payment schedule and software plan.

• Proprietary hardware for countertop and mobile use
• App marketplace
• Plan-dependent inventory, employee, and customer tools
• Offline payment settings on supported devices
• Payment and reporting functions tied to the selected merchant services arrangement

Clover user reviews are mostly positive for its POS hardware, reporting tools, app marketplace, and industry-specific setup options. Users especially like Clover’s flexibility, though some mention pricing, reseller differences, and contract terms as drawbacks.

SumUp is a mobile-first POS and payments provider designed for microbusinesses, seasonal sellers, and hobbyists.

I would consider SumUp for a seller who needs straightforward card acceptance and does not want to manage a larger POS setup. Its free option can suit occasional selling, while paid POS tools are available for businesses that need more.

SumUp vs Square

• Square offers a broader business software ecosystem. SumUp is worth comparing when payment acceptance and a simple device setup are the priorities.
• On their free plans, SumUp’s published in-person fixed fee is 5 cents lower than Square Free’s. At 400 transactions per month, that difference is $20, before comparing equipment or other costs.

Who should use SumUp

• Seasonal sellers, hobby sellers, pop-up vendors, and mobile businesses
• Low-volume businesses that want card readers and no monthly software fees
• Sellers that only need simple payment acceptance instead of a full POS system

• Free: $0/month
• POS Plus: $49/month
• In-person processing: 2.6% + 10 cents
• Online or manually entered payments: 3.5% + 15 cents
• Hardware: Priced separately; compare the current reader or terminal offer

The Free and POS Plus options use the same published standard processing rates. Additional services and hardware should be priced separately.

• Mobile and standalone payment devices
• Basic POS and payment tools
• Invoicing options
• Tipping and refunds
• Optional POS and customer engagement services

SumUp user reviews are mostly positive for its simple setup, affordable card readers, and easy mobile payment tools. Users especially like SumUp for low-volume or occasional selling, though some mention limited POS features and support issues as drawbacks.

KORONA POS is a cloud-based POS system designed for retailers that need advanced inventory control and flexibility. It serves businesses such as vape shops, liquor stores, bakeries, and ticketed venues.

I would shortlist KORONA POS for a specialty retailer that wants stock controls and a choice of supported payment integrations. Before switching, I would confirm that the proposed processor, terminal, and software configuration work together.

Square also offers inventory and age verification features, so the comparison should focus on the specific purchasing, reporting, and checkout procedures your store needs.

KORONA POS vs Square

• Square is cheaper and easier to use for single-location retailers that want a simple POS with integrated payments.
• KORONA POS is worth considering for specialty retail functions, processor choice, and configurations involving multiple terminals or locations.

Who should use KORONA POS

• Multi-location retailers and specialty stores with advanced inventory needs
• Vape shops, liquor stores, bakeries, convenience stores, and ticketed venues
• Retailers that want payment processor flexibility and more inventory customization than Square offers

• Core: $59 per terminal per month
• Retail: $79 per terminal per month
• Plus: $99 per terminal per month
• Hardware: Custom quote
• Processing and additional modules: Confirm separately

KORONA POS charges by terminal, so a starting price for one register should not be presented as the total for a multi-register store.

• Inventory management with reorder levels, counting schedules, and labeling
• Flexible payment processing options
• Ticket sales and membership management options
• Loss prevention tools with customizable staff permissions
• Hardware and accounting integrations, subject to compatibility and package requirements

KORONA POS user reviews are mostly positive for its inventory tools, customization options, and support for specialty retail businesses. Users especially like its flexibility for multi-location and regulated stores, though some mention setup time and a learning curve as drawbacks.

POS Nation is a POS system designed for specialty retail environments such as liquor stores, convenience stores, and tobacco shops. Its hardware options, inventory tools, and age verification features make it a strong fit for these operations.

I would choose POS Nation over a general-purpose checkout when the store needs functions such as case-break inventory, lottery tracking, or ID scanning. Those are more useful reasons to switch than a general claim that Square lacks retail inventory tools.

Age verification software supports staff procedures; it does not guarantee compliance with state or local requirements.

POS Nation vs Square

• Square is more affordable and easier to set up, making it a better option for general-purpose small businesses.
• POS Nation offers tools like ID scanning and specialized inventory features designed for age-restricted retail businesses.

Who should use POS Nation

• Liquor stores, tobacco shops, convenience stores, and regulated retailers
• Businesses that need age verification and ID scanning
• Stores that need stronger case-break, perishable, lottery, or specialty inventory tracking

• Starter: $49 per month
• Growth: $99 per month
• Premium: $149 per month
• Hardware and the full configuration: Custom quote
• Advertised package conditions: A POS Nation processing agreement is required

• Age verification with manual entry and ID scanning
• Lottery ticket management
• Inventory bundles and promotional pricing
• Purchase ordering
• Case-break and perishable inventory tools
• Loss prevention reporting
• Options for scales, scanners, and self-checkout

POS Nation user reviews are mostly positive for its industry-specific tools, onboarding support, and inventory features for regulated retail. Users especially like its fit for liquor, tobacco, and convenience stores, though some mention setup time and occasional usability issues as drawbacks.

PaymentCloud is a payment processor that specializes in helping businesses apply for merchant accounts, including businesses in industries that standard processors may restrict.

I would consider PaymentCloud when industry eligibility is the main obstacle. Its value is in finding a processing arrangement that fits the products sold, transaction activity, and underwriting requirements.

Approval is not guaranteed, and an approved account may still include reserves, funding conditions, or ongoing reviews. I would compare the written agreement rather than assume a high-risk account provides unrestricted access to funds.

PaymentCloud vs Square

• Square is easier to set up and provides an all-in-one POS system with integrated payments and simple flat-rate pricing.
• PaymentCloud specializes in high-risk merchant accounts and offers customized payment processing arrangements for businesses that traditional processors often decline.

Who should use PaymentCloud

• High-risk merchants that Square does not support or may decline
• Businesses that need their specific products and business model evaluated before approval
• Merchants that need underwriting and application guidance

PaymentCloud uses custom pricing. Request an itemized quote covering:

• Percentage and per-transaction processing charges
• Monthly account, gateway, and virtual terminal fees
• Setup, PCI, chargeback, and cancellation charges, if applicable
• Reserve requirements, funding schedules, and release conditions
• Hardware, software, and contract commitments

• High-risk merchant account placement
• Payment gateway options
• Fraud and chargeback management tools
• Payment methods determined by the approved account
• Account and application support

PaymentCloud user reviews are mostly positive for its high-risk merchant support, application guidance, and customer service. Users especially like having help with approval and underwriting, though some mention custom pricing and longer setup times as drawbacks.
