SaaS subscription billing architecture decides whether finance trusts your MRR numbers. Spygar designs billing modules on SaaS development and early hooks on SaaS MVP development.
Entitlements belong in your app; payment methods belong with the billing provider—confuse them and every plan change becomes a fire drill.
Recommended layers
- Plan catalog — features and prices
- Subscription lifecycle — trial, active, past_due, canceled
- Entitlements — what the tenant may use right now
- Provider sync — Stripe (or similar) webhooks + reconciliation
APIs often expose usage and entitlements—see SaaS API architecture and SaaS API integration. Enterprise invoicing needs may push you toward enterprise SaaS development.
