The payment processor that doesn't make you build your own reconciliation spreadsheet.
Stripe is the infrastructure layer between your customer's wallet and your bank account. It's not a point-of-sale system or an accounting tool—it's the plumbing that handles card processing, payouts, and the compliance overhead you'd otherwise own. For SaaS founders, Stripe solves a specific problem: you need to charge customers without becoming a payments expert. The platform handles PCI compliance, fraud detection, currency conversion, and regulatory filing in 195 countries. You get a REST API, webhooks, and a dashboard that actually tells you what happened to a transaction. The real value isn't the payment processing itself—it's the ecosystem. Stripe Connect lets you build marketplace dynamics (take a cut, pay sellers). Billing automates subscription logic, dunning, and proration. Radar catches fraud before it costs you. Sigma lets you query transaction data without exporting CSVs to a data warehouse. The tradeoff: Stripe takes 2.9% + 30¢ per transaction (US card). That's not cheap at scale, but it's transparent and you're not paying for features you don't use. The API is developer-friendly, which means your first integration takes days, not weeks. The documentation is the standard other payment processors aspire to. Where Stripe breaks down: if you process $10M+ annually, you'll want to negotiate rates. If you need to accept cash, checks, or wire transfers as primary payment methods, you're building custom workflows. If your customers are in markets with non-standard payment rails (certain Asian markets, Africa), you'll hit gaps in coverage.
