Whether you're running an online store, a freelance business, or a brick-and-mortar shop, accepting payments efficiently is critical to your success.

What Is a Payment Gateway?
A payment gateway is the technology that processes credit card and digital payments whether online, in person, or via mobile. It securely transmits payment information between the customer, merchant, and bank, authorizing (or declining) the transaction in seconds.
Key factors to compare when choosing a payment gateway:
- Transaction fees: Typically 1.5%-3.5% + a flat fee per transaction
- Monthly fees: Some charge monthly subscription fees; others are pay-as-you-go
- Payment methods supported: Cards, digital wallets, bank transfers, buy now pay later
- Integration options: Compatibility with your website platform, POS system, or app
- Payout speed: How quickly funds reach your bank account
- International support: Multi-currency and cross-border payment capabilities

How to Calculate Payment Processing Costs
Use this simple formula to estimate your monthly processing costs:
Monthly volume × transaction fee % + (number of transactions × flat fee)
Example: $10,000/month, 200 transactions, Stripe (2.9% + $0.30):
- $10,000 × 2.9% = $290
- 200 × $0.30 = $60
- Total monthly cost: $350 (3.5% effective rate)
The same volume with Helcim (interchange + 0.50% + $0.25, assuming 1.8% average interchange):
- $10,000 × 2.3% = $230
- 200 × $0.25 = $50
- Total monthly cost: $280 - saving $70/month ($840/year)
Frequently Asked Questions
What is the cheapest payment gateway?
For low-volume businesses (under $5,000/month), Square and Stripe offer the most straightforward pricing with no monthly fees. For higher-volume businesses, interchange-plus pricing from Helcim or negotiated rates from Adyen typically provide lower effective rates. The "cheapest" gateway depends entirely on your transaction volume, average transaction size, and card mix. Always calculate your actual monthly cost rather than just comparing headline rates.
Do I need a payment gateway and a merchant account?
Modern payment processors like Stripe, Square, and PayPal combine the payment gateway and merchant account into one integrated solution - you don't need to set them up separately. Traditional setups (common 10+ years ago) required a separate merchant account from a bank and a separate gateway. Today, most small and medium businesses are better served by all-in-one processors that handle everything under one roof.
How long does it take to receive funds from payment processing?
Standard payout times: Stripe (2 business days), Square (next business day), PayPal (1–3 business days to bank), Shopify Payments (2–3 business days). Most processors also offer instant or same-day payouts for an additional fee (typically 1–1.75% of the payout amount). For new accounts, processors may hold funds for 7–14 days initially as a risk management measure before moving to standard payout schedules.
Is Stripe or PayPal better for small businesses?
It depends on your needs. Stripe is better for businesses that sell primarily online and want powerful customization, developer tools, and lower rates for high volumes. PayPal is better for businesses that want immediate customer trust, easy setup without technical knowledge, and access to PayPal's 400M+ user base. Many businesses use both - Stripe as the primary gateway and PayPal as an additional option at checkout to maximize conversion.
What security standards should a payment gateway meet?
Any payment gateway you use should be PCI DSS (Payment Card Industry Data Security Standard) compliant - this is a non-negotiable baseline requirement. Look for gateways that offer tokenization (replacing card data with a secure token), 3D Secure authentication, and fraud detection tools. All gateways on this list are PCI compliant. Stripe's Radar and PayPal's fraud protection are among the most sophisticated in the industry.
Final Thoughts
The best payment gateway for your business depends on your sales channel (online vs. in-person), transaction volume, technical capabilities, and customer base. For most small businesses and e-commerce stores starting out, Stripe (online) or Square (in-person) offer the best combination of competitive pricing, ease of use, and growth potential.
As your business grows, revisit your payment processing costs annually - the right gateway at $1,000/month in sales may not be the right one at $50,000/month. A few hours of comparison shopping can save thousands in processing fees each year.
