Common Questions
What is the difference between a payment processor and a payment gateway?
A payment gateway is the software that securely captures and encrypts card data at checkout (like Stripe or Braintree). A payment processor handles the actual movement of funds between the customer's bank and your merchant account (like First Data or TSYS). Many modern providers like Stripe and Square combine both into a single service.
Should I choose interchange-plus or flat-rate pricing?
Flat-rate pricing (like Square's 2.6% + 10¢) is simpler but often more expensive for businesses processing over $10K/month. Interchange-plus pricing passes through the actual card network fees plus a fixed markup — typically saving 0.3-0.5% on each transaction. Switch to interchange-plus once you're consistently processing $10K+ monthly.
How can I reduce my payment processing fees?
Key strategies: negotiate rates after reaching $50K+/month in volume, encourage debit card and ACH payments (lower interchange), implement address verification to qualify for lower rates, avoid keyed-in transactions when possible, and review your monthly statement for hidden fees like PCI non-compliance charges or batch processing fees.
How do Stripe, Square, and PayPal compare for small businesses?
Stripe excels for online-first businesses with developer resources — its API is best-in-class. Square is ideal for retail/in-person sales with its free POS hardware and simple setup. PayPal offers the widest buyer recognition but charges higher fees (3.49% + 49¢ for standard checkout). Choose based on where most of your sales happen.
Key Terms
ACH Transfer
Electronic bank-to-bank transfer through the Automated Clearing House network. Costs $0.20-1.00 per transaction (vs. 2-3% for cards). Settlement: 3-5 business days standard, 1 day for same-day ACH. Ideal for recurring payments, B2B transactions, and high-value purchases where card fees are prohibitive.
Recurring Billing
Automatically charging a customer on a set schedule (weekly, monthly, annually) for subscription-based services. Requires stored payment credentials and explicit customer authorization. Stripe Billing, Chargebee, and Recurly are specialized platforms. Dunning management handles failed payment retries.
Checkout Conversion Rate
The percentage of users who complete a purchase after initiating checkout. Average: 45-55% for e-commerce. Optimized by: reducing form fields, offering guest checkout, supporting multiple payment methods, displaying trust badges, and implementing address auto-fill. Each 1% improvement directly increases revenue.
Buy Now, Pay Later (BNPL)
A payment option splitting purchases into 4-6 interest-free installments. Providers (Klarna, Affirm, Afterpay) pay the merchant upfront and collect from the customer over time. Merchant fees: 2-8% per transaction. Increases average order value 20-30% but attracts impulsive spending and higher return rates.
