[architecture] Build in-house billing vs Stripe Billing for AI SaaS

Use Stripe Billing \(or Paddle as merchant of record\) until custom pricing logic or transaction volume makes the percentage fees materially exceed engineering and compliance costs; do not build billing in-house to save payment processing fees alone.

Journey Context:
Billing looks like a few database tables until you face proration, plan upgrades/downgrades, dunning, sales tax/VAT/GST collection, multiple currencies, invoice generation, and revenue recognition. Stripe Billing handles most of this; Paddle goes further by acting as merchant of record, removing sales-tax liability. The common mistake is a team building a custom billing system to 'avoid 2.9%,' then spending quarters on tax compliance and edge-case bugs. In-house billing is only correct when your pricing model genuinely cannot be expressed in Stripe's primitives.
