Most buyers should pick Helcim.
Choose Helcim if you want published interchange-plus rates, no monthly account fee and automatic volume discounts. Choose Square if you want POS, online selling, team tools and marketing in one platform. Square lists a Free plan, but the published pricing details don't publish subscription prices or full processing costs. Helcim's rates are clearer, though transaction fees still apply and its hardware costs extra. For cost transparency, Helcim has the edge; for breadth of seller tools, Square does.

02Pricing compared
Helcim publishes interchange-plus rates and charges no monthly account fee, but every payment still has a processing cost. For monthly in-person volume up to $50,000, its listed margin is 0.40% + 8¢, plus interchange. Keyed and online payments at that volume carry a 0.50% + 25¢ margin, plus interchange. ACH is 0.5% + 25¢, capped at $6, with an added charge above $25,000.
Those margins fall at higher volume; above $5 million per month, Helcim says to contact sales. Hardware costs extra, including a $349 Smart Terminal or a $199 Card Reader. Square lists Free, Plus, Premium and Pro, but the published pricing details don’t publish subscription prices or full processing costs. Pro is for businesses processing over $250,000 yearly and has custom pricing. We’d favor Helcim for price transparency; Square’s total cost needs more checking.
03Features and depth
Helcim focuses on taking payments: cards online and in person, ACH, hosted checkout or payments added to an existing site, invoicing, and a virtual terminal for keyed or phone orders. It also advertises automatic volume discounts and transaction syncing with Xero and QuickBooks Online. That makes it the more payments-centered option in this comparison, though its listed features also cover several ways to collect payment.
Square combines payments and POS with seller tools. Its Free plan lists an online site, item library, invoicing and booking, plus checking and savings accounts. Plus adds advanced POS features, loyalty rewards and email campaigns; Premium adds advanced reporting and 24/7 phone support. Square also lists payroll, shift scheduling, marketing, app connections and Square AI business insights. Some extras cost more: for example, marketing texts are charged after the included allowance on Plus and Premium. Choose Square when those connected seller tools matter; don’t assume every feature is included in the plan price.
04Ease of use and learning curve
Our review scores rate Square’s ease of use at 8/10 and Helcim’s at 7/10, but they don’t explain setup time or the learning curve. The product details also don’t specify migration tools, onboarding steps for standard accounts, or training resources, so we wouldn’t treat either as a guaranteed quicker switch.
The practical choice depends on what you need to configure. Helcim’s listed scope centers on payment acceptance, checkout, invoicing and accounting connections. Square covers a wider set of seller operations, including POS, teams, marketing and cash-flow tools. That breadth may be useful if you want those tools together, but compare the plan details and costs for the functions you’ll actually use.
Questions people ask
Is Helcim cheaper than Square?
There isn’t enough published pricing here to call Square cheaper or more expensive overall. Helcim publishes transaction margins, with interchange added, and has no monthly account fee. Square’s plan subscription prices and full processing costs aren’t published in the published details, so compare its quote and fees against your payment mix.
Does Helcim charge a monthly fee?
Helcim says it has no monthly or annual subscription and no account monthly fees. It does charge transaction fees, including published margins for in-person and keyed or online payments, plus interchange. Optional hardware and some services, such as recurring payments, also have listed charges.
Does Square have a free plan?
Square lists a Square Free plan with POS payments, an online site, an item library, invoicing and booking, and checking and savings accounts. The published pricing details don’t state its subscription price or provide full payment-processing costs, so check those before comparing total cost with Helcim.
Which is better for online payments, Helcim or Square?
Both list online selling or payment options. Helcim offers online card processing, hosted checkout or payments added to an existing website, and a virtual terminal. Square lists an online site alongside its POS platform. The better fit depends on whether you prioritize Helcim’s published processing margins or Square’s broader seller tools.
