Accepting payments usually means supporting three "channels":
- CP (Card-Present): tap/insert/swipe in person (lowest fraud + usually lower cost)
- CNP (Card-Not-Present): online checkout, invoices, payment links
- Keyed / Virtual terminal: you type the card number (highest risk + usually highest cost)
- POS: your in-person "cash register" software + hardware (often bundled with processing)
Important: pricing changes, varies by country, and can vary by industry/MCC. The table below uses published US pricing from each provider's official pages where available.

Quick picks (by SMB type)
"I just need to take payments fast" (service businesses, solo operators)
- Square: simple setup + strong SMB POS + transparent flat rates.
- Stripe: great for online + invoices + "build what you want" workflows; POS is via Stripe Terminal integrations.
"I'm running a Shopify store (and maybe a retail counter too)"
- Shopify Payments: simplest if you're already on Shopify; avoid the 0.5-2% third-party transaction fee.
"I care about lowering cost as I scale volume"
- Helcim: interchange-plus with published markup schedule (automatic volume discounts as you grow).
"I want cards + PayPal + Venmo in one integration"
- Braintree: developer-friendly, all three payment methods in one SDK.
"I want a traditional 'merchant account' from a large US bank"
- Chase Payment Solutions: good for existing Chase business banking customers.
"I want PayPal wallet + cards"
- PayPal: useful when PayPal button conversion matters, but expensive for cards.
Pricing snapshot (US-published rates)
How to read this table
- Flat-rate providers quote an all-in rate (they keep the difference vs interchange).
- Interchange-plus providers pass through interchange + add a smaller markup.
| Provider | Best for | CP (in-person) | CNP (online checkout / invoices) | Keyed / Virtual terminal | POS offering |
|---|---|---|---|---|---|
| Stripe | Custom online flows, subscriptions, platforms | 2.7% + 5¢ (Terminal) | 2.9% + 30¢ (domestic) | Manual entry adds +0.5% | Not a “full POS” by default; supports in-person via Terminal + POS partners |
| Square | Fast setup + great SMB POS | 2.6% + 10¢ | 2.9% + 30¢ (Square Online / invoices online) | 3.5% + 15¢ (keyed-in / card on file) | Full POS ecosystem (hardware + POS app) |
| Shopify Payments | Shopify stores + omnichannel retail | Depends on plan (example Basic: 2.7% + 0¢ in person) | Depends on plan (example Basic: 2.9% + 30¢ online) | (Varies; often treated as CNP) | Shopify POS (tightest if you’re already on Shopify) |
| Helcim (Interchange+) | Cost transparency; better at higher volume | Markup example (Tier 1): 0.40% + 8¢ plus interchange | Markup example (Tier 1): 0.50% + 25¢ plus interchange | Included in card-not-present/recurring tiers | Terminals + invoicing/VT; not a “Square-style POS” bundle |
| Chase Payment Solutions | Current Chase Users | 2.6% + 10¢ | 2.9% + 25¢ | 3.5% + 10¢ | Offers a range of terminals and POS solutions |
| PayPal (Business Fees) | PayPal wallet conversion + cards | 2.29% + 9¢ | 3.49% + 49¢ (PayPal checkout) | 3.5% + 15¢ (Virtual Terminal) | Depends on PayPal product availability in your market |
| Braintree (PayPal) | Developer-friendly cards + wallets | (Typically used for online, not SMB POS) | 2.59% + 49¢ (standard) | (Depends on setup) | Not a POS suite; more of a payments platform |
The "Geography Gap" (US vs. EU)
When a US company sees a 1.2% rate for Europe, they need to understand that this only applies to Local-to-Local transactions.
| Factor | United States (Domestic) | Europe (EEA Domestic) | The "US SMB" Reality |
|---|---|---|---|
| Interchange Cap | None (Avg. 1.8% – 2.2%) | Capped at 0.3% | US rates fund the "Cashback" culture. |
| Card Mix | High Rewards/Infinite | Basic Debit/Credit | Premium US cards cost more to process. |
| International | +1.5% surcharge | +1.5% surcharge | A US company selling to EU pays more. |
The "True Cost" Table for a US Merchant
Instead of showing "Europe is 1.2%," show what a US-registered LLC pays when selling into these regions.
Scenario: $10k Monthly Sales | $20 Average Ticket | Using Stripe/Square (US Entity)
| Region of Customer | Base Rate | Intl. Surcharge | Total Cost ($10k) | Why? |
|---|---|---|---|---|
| USA Customer | 2.9% + $0.30 | $0 | $440 | Standard flat rate. |
| Canada Customer | 2.9% + $0.30 | +1.5% | $590 | Cross-border assessment. |
| Europe Customer | 2.9% + $0.30 | +1.5% | $590 | Plus possible 1-2% FX fee. |
| UK Customer | 2.9% + $0.30 | +1.5% | $590 | Brexit ended the EU caps for UK-US. |
The "Ticket Size" Visual
For your $20 ticket size example, the "Fixed Fee" ($0.30) is the silent killer. On your site, I recommend a call-out box like this:
🚨 The $0.30 Penalty: On a $100 transaction, $0.30 is only 0.3%. On a $20 transaction, $0.30 is 1.5%. Total Effective Rate for a $20 item: 2.9% + 1.5% = 4.4%.
Grouping by "SMB Profile"
Instead of just by country, group them by how they help a US company manage global risk:
Group A: The "Localizers" (Best for US companies selling globally)
- Adyen: Routes payments locally in Europe/Asia to avoid the +1.5% international fee.
- Airwallex: Allows you to collect USD, EUR, and GBP into local "wallets" so you never pay the 2% FX conversion fee.
- dLocal: Specifically for "Hard Markets" (Brazil, Nigeria, India) where US cards often fail.
Group B: The "Revenue Optimizers" (Best for US domestic services)
- Stax / Helcim: They use Interchange Plus. Because they don't charge a flat 2.9%, when a customer uses a basic "no-rewards" debit card, the merchant only pays ~1.2% instead of 2.9%.
Group C: The "Ecosystems" (Best for Operations)
- Shopify / Square: You pay a premium (higher fees) for the convenience of inventory and shipping being in one place.
Summary "Rule of Thumb" for your Site
- Under $10k/mo: Use a Flat-Rate (Square/Stripe). The simplicity is worth the cost.
- Over $10k/mo: Move to Interchange Plus (Helcim).
- Over $50k/mo: Move to a Subscription model (Stax/Payment Depot).
- Selling Internationally? Use a "Global Orchestrator" (Adyen/Airwallex) or you will lose 4-6% of your revenue to "hidden" cross-border fees.
