Enterprise Tech — Production-Grade SaaS Platforms

Build a SaaS Platform
That Scales to 1,000 Tenants
Without Rewriting.

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.

Architecture Decision

Three Multi-Tenancy Models — and Which One Your Product Needs

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.

Model 1 — Shared Database

Single DB, Tenant ID Column

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.

Infrastructure costLowest
Data isolationLogical (not physical)
Max tenantsUnlimited
Per-tenant backupsComplex
SOC 2 / HIPAAWith extra controls
Noisy neighbour riskPresent
Best for: High-volume B2C SaaS, freemium products, startups optimising for cost at early stage.
Model 2 — Schema per Tenant

One DB, Separate Schema Per Tenant

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.

Infrastructure costModerate
Data isolationStrong (schema boundary)
Max tenants~1,000 schemas (Postgres)
Per-tenant backupsNative (pg_dump per schema)
SOC 2 / HIPAAGood baseline
Noisy neighbour riskLow
Best for: B2B SaaS with 10-500 enterprise tenants, compliance requirements, separate migration windows per tenant.
Model 3 — Database per Tenant

Dedicated Database Per Tenant

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.

Infrastructure costHighest
Data isolationPhysical — maximum
Max tenantsDepends on provisioning
Per-tenant backupsNative, independent
SOC 2 / HIPAA / GDPREasiest to achieve
Noisy neighbour riskZero
Best for: Enterprise SaaS selling to large corporates, healthcare, financial institutions with strict data residency requirements.
What We Build

The Six Layers of a Production SaaS Platform

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.

6

Frontend Application Layer

Next.js App Router with tenant-aware routing, SSR for performance, role-based UI rendering, and a design system that scales with your product.

5

API Layer + Auth

REST or GraphQL API with JWT auth, refresh token rotation, tenant context injection per request, and rate limiting per tenant/plan.

4

Billing and Subscription Engine

Stripe integration — plans, trials, seat-based or usage-based pricing, proration, dunning, invoice PDF generation, and a self-serve billing portal.

3

Data Layer + Multi-Tenancy

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.

2

Background Jobs and Notifications

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.

1

Infrastructure and Observability

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.

Billing Setup

Stripe SubscriptionsStripe MetersStripe Portal

Supports flat-rate plans, per-seat plans, usage-based billing, freemium tiers, and annual discount logic. Webhook handlers for all payment lifecycle events.

Auth Options

NextAuth.jsAuth0ClerkCustom JWT

SSO/SAML for enterprise tenants, magic link for low-friction onboarding, social OAuth for consumer products. MFA configurable per tenant.

Billing Architecture

How Subscription Billing Flows Through Your SaaS

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.

Tenant Signs Up

Trial period starts, feature access granted at trial tier, Stripe customer record created

Plan Selected + Card Added

Stripe subscription created, prorated billing for mid-cycle starts, webhook confirms payment

Access Unlocked

Webhook triggers RBAC update in your DB — tenant access reflects paid plan within seconds

Renewal Cycle

Stripe auto-charges monthly/annually. Invoice emailed. Failed payment triggers dunning sequence

Cancellation / Churn

Access downgraded at period end. Data retained per retention policy. Win-back email triggered

What Is Included

Every Production SaaS Naraway Delivers Includes These by Default

These are not add-ons. They are the table stakes for a SaaS that enterprise customers will trust and your team can maintain.

Role-Based Access Control (RBAC)

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.

Audit Log for All Data Actions

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.

Admin Dashboard with Tenant Management

Internal admin panel for your team — view all tenants, subscription status, usage, impersonate sessions for support, suspend/reactivate accounts, and push announcements.

Usage Analytics Per Tenant

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.

Security Baseline (OWASP Top 10)

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.

Multi-Region and Data Residency Support

Deploy tenant data in specified regions for GDPR, data localization laws, or enterprise contract requirements. Tenant region selection at onboarding with routing handled automatically.

How We Build

From Architecture Decision to Production-Ready Platform

Naraway follows a structured SaaS build process — starting with architecture, not UI. The foundation is designed before a single frontend component is written.

Frequently Asked

SaaS Development — Technical Questions Answered

Multi-tenancy means a single deployed application serves multiple customers (tenants), each with their own isolated data and configuration. There are three models: shared database with tenant ID column (simplest, lowest cost), separate schemas per tenant (moderate isolation), and separate databases per tenant (maximum isolation, highest cost). Naraway chooses the right model based on your compliance requirements, customer size, and pricing structure.
A production-ready SaaS MVP with authentication, multi-tenancy, subscription billing, and a core feature set typically takes 10-16 weeks depending on complexity. This includes auth flows, tenant onboarding, Stripe billing integration, admin dashboard, and basic analytics. A clickable prototype can be delivered in 2-3 weeks before full build begins.
Naraway recommends Next.js (App Router) and Node.js/Express or Django for the API layer, PostgreSQL for the database, Redis for caching and job queues, and AWS or GCP for infrastructure. For billing, Stripe is the standard. Stack decisions are made based on your team's future hire profile and the specific performance characteristics of your product — not on preference alone.
Stripe is integrated for subscription management — plans, trials, upgrades, downgrades, proration, invoice generation, and webhook handling for all payment events. A billing portal is embedded in your app so customers self-manage their subscriptions. Dunning (failed payment recovery) is configured out of the box. For usage-based billing, Stripe Meters reports metered usage against subscription tiers.
Naraway builds in: tenant data isolation at the database query level (row-level security or schema separation), OWASP Top 10 protections (SQL injection, XSS, CSRF), JWT and session management with refresh token rotation, rate limiting per tenant, input validation at every boundary, audit logging for all data-touching actions, and HTTPS everywhere. For products requiring SOC 2 or ISO 27001 compliance, additional controls are architected from the start.
