Best Credit Card Processing Companies in 2026

Square remains the simplest way for a small shop, cafe, or market stall to start taking cards. The Free plan has no monthly fee, and published 2026 rates are 2.6 percent plus 15 cents in person and 3.3 percent plus 30 cents online. The free point-of-sale app covers sales, inventory basics, and reporting, and hardware starts with an inexpensive reader.

The catch is scale. Flat rates are easy to understand, but they cost more than interchange-plus pricing once monthly card volume grows. Square Plus, at 49 dollars per month, and Premium, at 149 dollars per month, lower online rates to 2.9 percent plus 30 cents, which only pays off above a certain volume. For a new or low-volume business selling mainly in person, Square is still the easiest pick.

Stripe is the default for online businesses that need more than a checkout button. Published standard online pricing is 2.9 percent plus 30 cents, with no monthly fee for the core payments product, and Stripe Billing handles subscriptions, trials, and invoicing. Developers get thorough documentation and ready-made checkout pages, which shortens the build for a new store or software product.

In-person selling is possible through Stripe Terminal, with published in-person rates from 2.7 percent plus 5 cents, but hardware is an added purchase and the setup is more technical than Square. Chargebacks carry a 15 dollar fee. If you sell mainly online, run subscriptions, or need developer tools, Stripe is the strongest all-round choice here.

Helcim is the pick for owners who want to see exactly what they pay. It uses interchange-plus pricing, meaning you pay the card networks actual interchange cost plus a Helcim markup, with published in-person pricing of interchange plus 0.40 percent plus 8 cents and online pricing of interchange plus 0.50 percent plus 25 cents. There is no monthly fee, and volume discounts apply automatically as sales grow, up to a large reduction in the markup.

That transparency helps as volume rises, since flat-rate providers keep the difference when interchange costs fall. The trade-off is complexity, since your effective rate moves with card mix rather than staying fixed. Helcim also includes free point-of-sale tools and a Fee Saver surcharging feature where allowed. For businesses processing more than about 10,000 dollars a month, Helcim is often the cheapest honest option.

PayPal earns its place through customer familiarity. Millions of buyers already hold a PayPal account, and offering it at checkout can lift conversion for stores whose customers expect it. Published rates include 2.29 percent plus 9 cents for in-person payments through PayPal point-of-sale tools, while online PayPal Checkout is published at 3.49 percent plus 49 cents, which is higher than Stripe or Square online.

That online rate is the main weakness, and it makes PayPal a poor sole processor for a high-volume online store. It works best as an added payment option alongside Stripe or Square, or as the main option for a small seller whose customers strongly prefer PayPal. Watch account hold policies too, since sudden holds are a common complaint among new sellers.

Shopify Payments makes sense only in one situation, which is also the situation where it makes the most sense. If your store already runs on Shopify, it removes the need for a separate payment gateway, keeps reporting inside one dashboard, and avoids the extra transaction fee Shopify charges when you use an outside processor. Card rates vary by Shopify plan, so check the plan page for your tier.

Outside Shopify, this provider has no role. A business selling in person, through another platform, or by invoice needs a separate processor. For a Shopify store owner, though, the convenience and the avoided third-party fee make Shopify Payments the natural default, with Stripe or PayPal as added checkout options where useful.

Clover is a point-of-sale system first and a processor second, which is why restaurants and retailers choose it. The hardware range covers counter terminals, handheld devices, and kitchen displays, and the software handles orders, tables, inventory, and staff permissions. Published software plans start at 14.95 dollars per month, with higher tiers adding more features.

The main caution is that Clover processing is often sold through resellers, so rates, contract length, and exit fees can vary more than with Square or Stripe. Published card-present rates in comparisons run around 2.3 to 2.6 percent plus 10 cents, but your written proposal is what counts. Get the full fee schedule and contract terms in writing, and compare hardware costs, before you commit.

Payment Depot suits businesses that already process enough card volume for a subscription model to pay off. Instead of a percentage markup, you pay a monthly subscription, starting at 79 dollars per month on published comparisons, plus wholesale interchange costs and a small per-transaction fee. For a high-volume seller, that structure can beat flat rates by a clear margin each month.

Low-volume sellers should stay away, since the monthly fee alone can exceed any rate saving. Payment Depot is also best judged on a full month of your own statements, not on a headline rate. If your card volume is high and steady, request a savings estimate based on your actual card mix before you switch.

Stax, formerly Fattmerchant, follows the same subscription idea as Payment Depot, with monthly plans starting at 99 dollars per month on published comparisons and interchange-plus transaction pricing on top. The appeal is predictable costs and a lower per-transaction markup as volume grows, plus built-in tools for invoicing and recurring payments.

As with Payment Depot, the monthly fee means Stax only makes sense once volume is high enough to cover it. Small sellers will pay less with Square, Stripe, or Helcim, all of which charge no monthly fee. Growing businesses that want subscription pricing with support included should compare Stax and Payment Depot on their own statements, not on marketing claims.

Toast is the restaurant specialist on this list. Its point-of-sale system is built around restaurant work, with tables, modifiers, kitchen display screens, handheld ordering, and online ordering in one package. That focus is why so many full-service and quick-service restaurants choose it over a general retail POS, even when a general tool would cost less.

Pricing is quote-based and varies by package, so check the current Toast page and request a written proposal for your restaurant size. Published comparisons put card rates in the range of 2.49 to 3.69 percent plus 15 cents, depending on plan and card type. For a restaurant that needs the full Toast feature set, the fit justifies the price. For a single food truck, Square or Clover may be simpler and cheaper.
