About Payments Tools

Payment processing is critical for any revenue-generating application, but building it from scratch is complex and risky. Modern payment platforms handle everything from credit card processing to subscription billing, invoicing, and fraud prevention, while ensuring PCI compliance and supporting global payment methods.

Stripe dominates the market with its developer-friendly APIs and extensive features, but alternatives like Paddle, Lemon Squeezy, and PayPal offer different advantages. Some platforms (Paddle, Lemon Squeezy) act as merchants of record, handling all tax compliance and VAT globally - perfect for SaaS businesses. Others (Stripe, Braintree) offer more control but require you to handle taxes yourself.

Choose based on your business model (one-time vs subscriptions), international requirements, tax complexity, and technical resources. Consider fees, supported payment methods, checkout experience, and whether you need features like subscription management, invoicing, or affiliate tracking.

Frequently Asked Questions

Stripe vs Paddle: which should I choose?

Stripe offers more control and lower fees (~2.9%) but you handle taxes yourself. Paddle is a merchant of record handling all taxes and compliance (~5% + fee), perfect for global SaaS. Choose Stripe for flexibility and control, Paddle for simplicity and tax compliance.

What does 'merchant of record' mean?

The merchant of record is the legal seller. Platforms like Paddle and Lemon Squeezy are the merchant of record, handling all taxes, compliance, and chargebacks for you. With Stripe, you're the merchant of record and must handle these yourself. MoR platforms simplify compliance but take higher fees.

How much do payment processors charge?

Varies by platform and volume. Stripe/PayPal: ~2.9% + $0.30 per transaction. Paddle: ~5% + $0.50. Lemon Squeezy: ~5% total. High-volume businesses can negotiate lower rates. Factor in currency conversion, international fees, and any platform fees.

Do I need PCI compliance for payment processing?

If using modern payment platforms like Stripe, Paddle, or PayPal, they handle PCI compliance for you. You never touch raw card data. However, you still have some compliance responsibilities depending on your integration method. Using hosted checkouts minimizes your burden.

Can I handle global payments and multiple currencies?

Yes! Most platforms support international payments. Stripe supports 135+ currencies. Paddle and Lemon Squeezy handle multi-currency pricing and global taxes automatically. Consider currency conversion fees and local payment methods (Alipay, iDEAL, etc.) for international customers.
