Multi-tenancy, subscription billing, role-based access control, and audit logging are not features you add later. Naraway architects them in from day one — so your SaaS does not become technical debt the week your first 100 customers arrive.
The tenancy model you choose at the start determines your infrastructure cost, your data isolation guarantees, your compliance ceiling, and your migration effort later. Most early SaaS founders choose the wrong model and pay for it at scale.
All tenants share one database. Every table has a tenant_id column. Queries always filter by tenant_id. Row-level security (RLS) enforces isolation at the database engine level.
Each tenant gets its own database schema within a shared PostgreSQL instance. Tables are identical in structure across schemas. Migrations run per-schema. Connection pooling via PgBouncer.
Each tenant has a completely separate database instance. Maximum isolation. Each database can run on a different server, region, or configuration. Most expensive but cleanest boundary.
A SaaS is not a web app with a subscription button. These six layers must be designed, not assembled as afterthoughts. Naraway builds them all — and documents each so your team can own them.
Next.js App Router with tenant-aware routing, SSR for performance, role-based UI rendering, and a design system that scales with your product.
REST or GraphQL API with JWT auth, refresh token rotation, tenant context injection per request, and rate limiting per tenant/plan.
Stripe integration — plans, trials, seat-based or usage-based pricing, proration, dunning, invoice PDF generation, and a self-serve billing portal.
PostgreSQL with chosen tenancy model, Redis for caching and job queues, S3 for file storage with per-tenant bucket policies, full-text search via Elasticsearch or pg_tsvector.
BullMQ or Celery for async processing, email via Resend or AWS SES, in-app notifications, webhook delivery to customer endpoints with retry logic and delivery logs.
AWS/GCP with auto-scaling, CI/CD via GitHub Actions, Datadog or Grafana for monitoring, Sentry for error tracking, and structured logging with per-tenant context.
Supports flat-rate plans, per-seat plans, usage-based billing, freemium tiers, and annual discount logic. Webhook handlers for all payment lifecycle events.
SSO/SAML for enterprise tenants, magic link for low-friction onboarding, social OAuth for consumer products. MFA configurable per tenant.
A SaaS billing system is not just a Stripe payment button. It is a state machine that handles trials, upgrades, downgrades, failures, and cancellations — and keeps your access control in sync with payment state at every moment.
Trial period starts, feature access granted at trial tier, Stripe customer record created
Stripe subscription created, prorated billing for mid-cycle starts, webhook confirms payment
Webhook triggers RBAC update in your DB — tenant access reflects paid plan within seconds
Stripe auto-charges monthly/annually. Invoice emailed. Failed payment triggers dunning sequence
Access downgraded at period end. Data retained per retention policy. Win-back email triggered
These are not add-ons. They are the table stakes for a SaaS that enterprise customers will trust and your team can maintain.
Granular permission system with roles (Owner, Admin, Member, Viewer) and resource-level permissions. Tenant admins can manage their own team's access without contacting support.
Every create, update, delete, and permission change is logged with user ID, timestamp, IP address, and changed fields. Queryable by tenant admins. Required for SOC 2 compliance.
Internal admin panel for your team — view all tenants, subscription status, usage, impersonate sessions for support, suspend/reactivate accounts, and push announcements.
Track API calls, feature adoption, active users, and storage usage per tenant. Feeds into billing for metered plans. Powers your customer success team's health scoring.
SQL injection prevention via parameterized queries, XSS protection, CSRF tokens, secure HTTP headers, input validation at every boundary, rate limiting, and dependency scanning in CI.
Deploy tenant data in specified regions for GDPR, data localization laws, or enterprise contract requirements. Tenant region selection at onboarding with routing handled automatically.
Naraway follows a structured SaaS build process — starting with architecture, not UI. The foundation is designed before a single frontend component is written.
