How to Choose a Payment System for International Business: Complete Guide

Methodology for choosing a payment provider for global sales: 7 criteria, Stripe vs Paddle vs LemonSqueezy vs Adyen comparison, regional specifics, and common mistakes.

Why Payment Selection Is Strategic

The payment system isn’t just infrastructure for accepting money. It’s the point where your product’s conversion either happens or doesn’t. Baymard Institute research shows 17% of users abandon carts due to unavailable payment methods. In international markets, this rises to 25% when local preferences aren’t accounted for.

Methodology: 7 Selection Criteria

Criterion 1: Payment Geography

Question: Where are your payers located, and what currencies do they want to use?

This is the first and most important filter. A provider might work perfectly in the US but not support SEPA Direct Debit for Europe or Alipay for China.

Criterion 2: Integration Model

Model Examples Pros Cons
Payment Gateway Stripe, Braintree Full checkout control Complex integration, PCI on you
Merchant of Record Paddle, LemonSqueezy Taxes, compliance on provider Higher fees
Hybrid Adyen Many methods, managed risk Expensive for small biz

For SaaS and digital goods, MoR often wins: the fee difference (Paddle 5% vs Stripe 2.9%) is offset by zero tax compliance costs and chargeback handling.

Criterion 3: Total Fees

Example for $100K/month SaaS:

  • Stripe: ~$3,200/month + FX + cross-border
  • Paddle: $5,000/month (all-in: taxes, chargebacks, compliance)
  • Real difference depends on international transaction share

Criterion 4: Taxes and Compliance

Via Payment Gateway: you’re the merchant of record. Track tax thresholds per country. EU VAT: OSS/IOSS registration required. US Sales Tax: Economic Nexus per state.

Via MoR: provider is the legal seller. Collects and remits taxes. You receive net payout. Saves $500-2,000/month on accounting.

Criterion 5: Subscriptions and Recurring Billing

Subscriptions ✅ Billing

Usage-based

Stripe Billing is the most powerful for subscription businesses.

Criterion 6: Checkout and Conversion

Every second of checkout loading time reduces conversion by 2-4%. Consider: hosted vs embedded, customization, localization, mobile optimization (60%+ of payments).

Criterion 7: Payouts

Provider Settlement Min Payout
Stripe T+2 US, T+7 EU $1
Paddle T+1 $100
LemonSqueezy Weekly $50
Adyen T+3 $500

Regional Specifics

  • US/Canada: Cards + Apple Pay/Google Pay. Stripe is standard.
  • Europe: Cards + SEPA Direct Debit + local methods. MoR simplifies VAT.
  • Asia: Alipay/WeChat Pay in China, GrabPay/GCash in SEA. Alipay+ unifies multiple methods.
  • Latin America: High cash/local method share. Mercado Pago dominates.

Common Mistakes

  1. Focusing only on fees — saving 1% on fees can cost 5% in conversion
  2. Ignoring tax obligations — gateway without MoR = VAT responsibility in 27 EU countries
  3. Underestimating integration time — complex API can take 2-3 weeks
  4. Not checking payout options — ensure provider pays out to your country/currency
  5. Single-provider dependency — diversification reduces account freeze risk

Selection Checklist

  1. Define payer geography — 80% of decision depends on this
  2. Choose model: MoR for digital goods/SaaS, gateway for flexibility
  3. List required payment methods for your market
  4. Calculate total cost (including FX, chargebacks, taxes)
  5. Verify compatibility with your stack
  6. Assess migration difficulty
  7. Test checkout with real users from target countries
  8. Connect a secondary provider as backup

Quick Recommendations

  • Indie dev, digital product, global: Paddle or LemonSqueezy
  • SaaS subscriptions, US/EU focus: Stripe
  • Enterprise, many payment methods: Adyen
  • Selling to China: Alipay + WeChat Pay (both mandatory)
  • Latin America: Mercado Pago or dLocal
  • Maximum savings: start with MoR, switch to gateway at $50K+/month

Payment infrastructure is your foundation. Spend time choosing now to avoid weeks of migration later.
