Question 1

What is the best payment processor for small businesses?

Accepted Answer

The best payment processor depends on your sales channel and volume. Stripe is the best choice for online-first businesses that need a developer-friendly API with 135+ currencies and global reach. Square is the best choice for brick-and-mortar businesses that need free POS software and integrated hardware. PayPal is the best choice for businesses that want the fastest setup and benefit from 400M+ consumer trust signals. Helcim is the best choice for businesses processing $10,000+/month that want the lowest possible fees through interchange-plus pricing.

Question 2

Which payment processor has the lowest fees?

Accepted Answer

For low-volume businesses, Stripe's pay-as-you-go model (2.9% + $0.30) is competitive and transparent. For businesses processing $10,000+/month, Helcim's interchange-plus pricing delivers the lowest effective rates — typically 30-50% less than flat-rate processors. Square's free POS software makes it the most affordable for brick-and-mortar startups. PayPal is generally the most expensive option for international transactions due to 3-4% FX fees.

Question 3

How to choose the right payment processor for your business?

Accepted Answer

Start with your primary sales channel. Online-first businesses should evaluate Stripe's API and global reach. Brick-and-mortar businesses should start with Square's free POS ecosystem. Businesses selling on eBay, Etsy, or similar marketplaces benefit from PayPal's native integrations. As your volume grows past $10,000/month, compare your effective rate against Helcim's interchange-plus pricing. Always factor in FX costs if you sell internationally — Stripe's ~1% markup is significantly cheaper than PayPal's 3-4%.
