Helcim (Interchange-plus, no monthly fee) review 2027

What problem does Helcim solve for small businesses?

Helcim is built for the business that has outgrown a starter setup and now feels every basis point of card processing. Its pitch is wholesale-style pricing without the monthly fee or the sales rep, and it published every number before we asked. The tagline says the same thing in plainer terms: interchange-plus pricing with no monthly fee and automatic volume discounts, with rates published on the website.

In our test basket, that produced a measured cost of $658 a month on $25,000 in card payments. The verdict headline is blunt about why that matters: lowest cost at real volume. Alongside the rate card, Helcim includes invoicing, recurring billing and a customer portal, so a service business can bill a client and take a card without bolting on another subscription.

It is not for everyone. Our verdict says restaurants will need something else, and the best-for row points at businesses over about $10k a month. Below that threshold the interchange-plus model has less room to work, and a flat-rate processor may be simpler to reason about.

How did Helcim score in our testing?

Helcim finished on 8.9 out of 10 across five weighted criteria. The breakdown shows where that score came from.

• Processing fees and total cost: 30 out of 30. We measured the real cost of taking $25,000 a month in card payments on each system, including rate, per-transaction fee, monthly software, hardware and any early-termination clause. Helcim took full points.
• Hardware and reliability: 15 out of 20. This covers terminal build, offline mode when the internet drops, receipt printing, cash drawer and scanner support. Helcim lost points here, and the offline limitation is the reason.
• Features for the trade: 15 out of 20. Inventory, menus and modifiers, table service, appointments, staff rotas, loyalty and online ordering. Helcim covers general retail and service needs but has no restaurant-specific tooling.
• Reporting and integrations: 14 out of 15. Sales reports, accounting sync, payroll, ecommerce and the API. This is a strong area, just short of full marks.
• Support and terms: 15 out of 15. Hours reachable, how fast a dead terminal is replaced, contract length and how funds are held. No contract and no early-termination clause helped it take every point.

Where Helcim stands out

The measured cost is the headline. That is not a promotional rate or a first-year discount; it follows from interchange-plus pricing, where the processor's markup sits on top of the card networks' wholesale cost rather than replacing it with a single flat percentage.

Helcim publishes those rates openly, and the markup steps down automatically as volume grows. There is no monthly fee, no contract and no early-termination clause, so leaving costs nothing but the effort of moving. Invoicing, recurring billing and a customer portal are included rather than sold as add-ons, which matters to anyone billing clients on a schedule.

What you get: rates, hardware and terms

The published rate card for in-person cards is interchange + 0.40% + 8¢. Software is 0 USD/mo, and there is a free software tier. Hardware starts at 99 USD. Offline mode is limited. Payouts land in 2 business days. There is no contract. The best-for row reads: businesses over about $10k a month.

Those nine rows are the whole commercial picture. The low hardware entry point keeps the upfront cost small, and the absence of a monthly software charge means a quiet month costs you nothing beyond the transactions you actually ran. The trade-offs are equally clear: limited offline acceptance and a two-day payout rather than next-day.

How does Helcim compare with Square, Toast and Clover?

Square scored 8.9, the same as Helcim, with free software, no contract, a $59 reader and a full business suite behind it. Square's in-person rate is 2.6% + 15¢ and our maths put it at 785 USD/mo on $25k. Square offers next-business-day payouts, or instant for 1.75%, and offline mode with a per-transaction cap. Against Helcim it wins on payout speed and offline capability, and loses on measured cost.

Toast scored 8.5 and is built for restaurants and nothing else: coursing, modifiers, kitchen displays, online ordering and handhelds that survive a service. Its rate runs from 2.49% + 15¢ on the paid plan to 3.09% + 15¢ on the free plan, software is 69 USD/mo, and our maths put it at 787 USD/mo on $25k. Hardware starts at 799 USD, offline mode is full, payouts are next business day, and some plans carry a 1–3 year contract. Toast beats Helcim on restaurant features and offline mode; Helcim beats it on cost, contract and hardware entry price.

Clover scored 8.2 with proper countertop hardware and a large app marketplace. Bought directly, its rate is 2.6% + 10¢, software is 14.95 USD/mo, and our maths put it at 770 USD/mo on $25k. Hardware starts at 299 USD, offline mode is supported, payouts are next business day, and there is no contract direct — though resellers can tie you to up to 3 years. Clover is ahead on offline mode and payout speed; Helcim is ahead on measured cost and on having no reseller layer between you and the terms.

Where Helcim falls short

Three things cost it points. Offline card acceptance is limited compared with Square or Clover, so a dropped connection is a real problem rather than a brief inconvenience. There are no restaurant-specific features like table maps or coursing, which is why our verdict sends restaurants elsewhere. And payouts take two business days rather than the next-day timing most rivals manage.

Our where-it-lost line names the first two directly: restaurant features and offline mode. If either is central to how you trade, the 8.9 score will not save you from a bad fit.

Is Helcim good value?

The price summary is simple: no monthly fee. On our $25,000-a-month basket the measured cost was 658 USD/mo, against 785 USD/mo for Square, 787 USD/mo for Toast, 770 USD/mo for Clover, 794 USD/mo for Shopify POS and 860 USD/mo for Lightspeed Retail. Helcim was the cheapest of the group we tested.

Value here is not just the lowest number. It is that the number is published, the markup falls as you grow, and there is no contract holding you in place if it stops being the cheapest option for your mix.

Who should buy Helcim?

Helcim is still right for shops and service businesses past the starter stage. The best-for row narrows it further: businesses over about $10k a month, where interchange-plus pricing and automatic volume discounts have enough volume to work with.

If you run a restaurant, or you cannot trade through a dropped connection, look at Toast, Square or Clover instead. If you sell the same stock in store and online, Shopify POS keeps one inventory across both. If your stock is genuinely complicated, Lightspeed Retail goes deeper. For everyone else taking cards at volume, Helcim is the cheapest total in our test.
