02 Stripe — Best for online payment processing
Stripe is the gold standard for online payment processing — used by Amazon, Google, Shopify, and millions of small businesses worldwide. No monthly fees, transparent per-transaction pricing, and the most developer-friendly payment API available. For any business accepting payments online — e-commerce, invoices, subscriptions, or donations — Stripe is the default choice.
✓ Pros
- No monthly or setup fees ever
- Best developer API in the industry
- Handles subscriptions and recurring billing
- Supports 135+ currencies
- Fraud detection included
- Connects to every major ecommerce platform
✗ Cons
- Requires developer knowledge for custom setups
- Account holds can occur for unusual activity
- In-person hardware is more expensive than Square
03 Square — Best for in-person payments
Square is the easiest way to accept in-person card payments. The free magstripe reader ships when you sign up, the mobile app turns any iPhone or Android into a card terminal, and the free POS software handles your whole operation. No monthly fees, no contracts, no minimums. For any business that primarily takes payments face-to-face, Square is the clear winner.
✓ Pros
- Free card reader included
- Works on any iOS or Android device
- Free POS software built in
- No monthly fees or contracts
- Instant deposit available for 1.75% fee
✗ Cons
- Account holds for unusual transactions
- Customer support can be slow
- Flat rate — not ideal for very high volume
04 PayPal — Best for consumer-facing businesses
PayPal is the most recognised payment brand in the world with 400 million active users. When customers see PayPal at checkout, trust is already established — particularly for older demographics who are cautious about unfamiliar checkout experiences. PayPal's fees are higher than Stripe for online transactions, but the conversion boost from brand recognition can offset that for some businesses.
✓ Pros
- Most trusted payment brand globally
- 400M+ customers already have accounts
- Buy Now Pay Later via PayPal Credit
- Venmo integration for US customers
- Good for international payments
✗ Cons
- Higher online fees than Stripe
- Account freezes and holds are common
- Customer service is notoriously poor
- Not ideal as your only processor
05 Shopify Payments — Best for Shopify store owners
If you sell on Shopify, using Shopify Payments eliminates all transaction fees completely — Shopify charges up to 2% per sale when you use a third-party processor. It is powered by Stripe under the hood and supports all major cards, Apple Pay, Google Pay, and Buy Now Pay Later options. Available in the USA and Canada.
✓ Pros
- Zero transaction fees on all Shopify plans
- Fully integrated — no separate setup
- Apple Pay, Google Pay, BNPL built in
- Chargeback protection included
- Available in USA and Canada
✗ Cons
- Only available on Shopify (requires subscription)
- Not available in all countries
- Less flexible for custom payment flows
06 Helcim — Best payment processor for Canadian businesses
Helcim is a Calgary-based payment processor built specifically for Canadian small businesses. Unlike Stripe and Square which use flat-rate pricing, Helcim uses interchange-plus pricing — meaning you pay the actual card network cost plus a small markup. For businesses processing over $5,000 per month, this almost always results in lower fees than flat-rate processors. No monthly fees ever.
✓ Pros
- Interchange+ pricing — usually lower than flat rate
- No monthly fees or minimums
- Built specifically for Canadian businesses
- Excellent customer service
- Free card reader included
- Volume discounts automatically applied
✗ Cons
- Interchange+ harder to predict vs flat rate
- Less well known than Stripe or Square
- Fewer third-party integrations
🇨🇦 Canadian tip
Canadian businesses often pay higher interchange fees than US businesses because of different card network rules. Helcim's interchange-plus model means you benefit directly when you process lower-cost debit transactions — which are extremely common in Canada. Well worth comparing against Stripe and Square if you process over $5,000/month.

At $10,000/month in sales, the difference between Stripe ($320) and PayPal ($398) is $936 per year. At $100,000/month, that gap becomes $9,360 per year. Getting your processor right is one of the highest-leverage financial decisions a small business makes.
08 Final verdict
- Best for online: Stripe — most powerful, transparent pricing, industry standard
- Best for in-person: Square — free reader, free POS, easiest setup
- Best for brand trust: PayPal — 400M users, BNPL, best conversion for consumer markets
- Best for Shopify: Shopify Payments — zero transaction fees, fully integrated
- Best for Canada: Helcim — interchange+ pricing, lower fees at volume, Canadian-built
✅ Our recommendation
Most small businesses should use Stripe for online payments and Square for in-person — both free to set up, no monthly fees, and reliable. Canadian businesses processing over $5,000/month should compare Helcim — the interchange-plus pricing frequently saves meaningful money.
