Square Alternatives in 2026

Shopify POS is the best Square alternative for a shop that already sells online on Shopify. Orders, inventory, and customer records stay in one system, so a sale in store updates the online stock at once, and an online order does not sell an item that left the shop an hour earlier. That sync is the main reason to choose Shopify POS over a standalone counter system.

The catch is stacked cost. Shopify POS starts with a Shopify plan, with Basic at $39 per month in recent listings, and POS Pro adds a further fee per location. In-person card rates through Shopify Payments are around 2.6% plus 10 cents on Basic in recent comparisons. For an online-first shop, that total is worth it. For a shop with no online store, a simpler POS may cost less.

Clover, from Fiserv, is a hardware-forward POS system with devices for counters, tables, and mobile sales. Its app marketplace covers inventory, loyalty, online ordering, and staff tools, and its hardware feels built for a busy counter. Direct Clover listings in recent comparisons show in-person rates from 2.3% plus 10 cents for restaurants to 2.6% plus 10 cents for retail, with software from about $14.95 per month on some direct plans.

The main risk is reseller pricing. Clover is sold through many partners, and the same hardware can carry very different monthly fees, rates, and contract terms. Some resellers bundle hardware into a multi-year lease, which can cost far more than buying direct. Get a written quote from Clover direct and from any reseller, compare the full term cost, and do not sign a long contract on a first call.

Toast is the best Square alternative for restaurants, because it is built around restaurant work: table maps, modifiers, split bills, kitchen display tickets, and handheld payment at the table. It also offers online ordering and guest tools that help a restaurant take orders beyond the dining room. For a full-service or quick-service restaurant, that depth beats a general retail POS.

The limit is scope and lock-in. Toast is less suited to a general retail shop, and its hardware only works with Toast, so switching later means replacing devices. Recent listings show POS plans from $69 per month, with in-person rates around 2.49% plus 15 cents on paid plans, though terms vary. Restaurants should test Toast on a busy service before committing, since speed at the pass matters more than any feature list.

Lightspeed Retail suits shops with large catalogues, several locations, or complex stock needs, such as apparel, bike, pet, or specialty retail. It handles variants, purchase orders, suppliers, and multi-location stock in a way that simpler POS tools do not, and it includes e-commerce tools so online and in-store stock can stay aligned. Reporting also helps a buyer spot slow stock before it ties up cash.

The drawback is price. Lightspeed Retail starts at $89 per month billed annually in recent listings, and processing rates vary, with recent comparisons showing around 2.6% plus 10 cents through Lightspeed Payments. That cost is hard to justify for a single small shop with a short product list. For a shop where inventory is the main job, Lightspeed earns its fee.

Helcim is the best Square alternative for sellers who want transparent, interchange-plus pricing. Instead of a flat rate on every card, Helcim passes through the card network cost and adds a margin, recently listed as 0.4% plus 8 cents in person. That model often wins for larger tickets and higher volumes, especially for debit cards and business cards where flat rates can be costly.

The catch is complexity. Interchange-plus statements show more detail than a flat-rate bill, so a seller needs to read them or trust the summary. Hardware is also separate, with readers listed around $199 in recent comparisons. For a low-volume seller, the saving may be small. For a growing business with steady card volume, Helcim is worth a quote alongside any flat-rate POS.

Stripe is best known for online payments, but it also offers Terminal for in-person card payments, which makes it a viable Square alternative for businesses that sell mainly online and take some payments in person. Its online rate is 2.9% plus 30 cents in recent listings, with Terminal in-person rates around 2.7% plus 5 cents. Subscriptions, invoicing, and developer tools are strong, which suits software, services, and subscription businesses.

The limit is POS depth. Stripe is not a full retail or restaurant POS out of the box, so a shop that needs inventory, table maps, or a counter register will need to pair Stripe with another POS or build a custom flow. For a business that already uses Stripe online and wants one payment provider for in-person sales, Stripe Terminal is a clean add-on.

PayPal Zettle, formerly iZettle, is a simple card reader and app system for mobile sellers, market stalls, cafes, and small shops. There is no monthly fee for the core service, and recent US listings show an in-person rate of 2.29% plus 9 cents, which is among the lowest flat rates in this list. The first reader is listed around $29 in some comparisons, which keeps startup costs low.

The trade-off is breadth. Zettle covers payments, simple inventory, and sales reports well, but it does not match Shopify for online stores, Toast for restaurants, or Lightspeed for large catalogues. It also links to PayPal, which helps for online checkout but adds a second fee structure to check. For a mobile seller who needs to take cards quickly, Zettle is an excellent low-cost pick.

SumUp is a pay-as-you-go payment system with low-cost card readers, aimed at markets, pop-ups, cafes, and mobile sellers. There is no monthly fee on the basic plan, and recent US listings show an in-person rate of 2.6% plus 10 cents, with online payments at a higher rate. The reader range starts at a low price, which makes SumUp easy to try for a single event.

The limit is POS depth. SumUp handles payments and basic sales well, but a shop that needs deep inventory, restaurant tools, or multi-location stock will outgrow it quickly. It is also a payment-first tool, not a full business system. For a seller who needs a cheap reader for occasional sales, SumUp is a practical Square alternative.
