# Build a product ready for its next customer.

SaaS product engineering

Design tenant isolation, subscriptions, onboarding and operational controls around the product you need to run.

## A product that knows each tenant

Illustrative workflow.

- Tenant context: Organisation and entitlement verified
- Product workspace: Data and actions scoped to that tenant
- Operations: Support access and usage recorded separately



## Tenancy is more than a database field

Build isolation through identity, queries, files, background jobs and support tooling. Connect onboarding, entitlements and billing events without letting commercial state weaken access boundaries.

Illustrative scenario, not a customer case study.

A SaaS platform serves separate Australian organisations from shared infrastructure.

Carry a validated tenant identity through requests, background jobs, caches and storage. Enforce isolation at data access boundaries instead of relying on UI filtering.

Verification: Test cross-tenant access attempts through every interface, including exports and scheduled jobs.

## Keep product growth inside dependable boundaries.

### Tenant isolation

Carry tenant identity through requests, jobs, files and caches, not just the main database query.

### Product onboarding

Connect account setup, permissions and subscription state to the product’s actual access rules.

### Product operations

Track releases, usage and support signals without exposing one customer’s data to another.

## Tenant isolation belongs in every execution path

### Add tenant filters only in the interface

Background jobs or an overlooked API can expose data across customer boundaries.

### Enforce context at every entry point

Test isolation at storage, API and task boundaries, including privileged support workflows.

## What your team receives

Included scope agreed before delivery.

- Tenancy model: Identity, storage, jobs and support access boundaries.
- Product lifecycle: Onboarding, entitlements and subscription-related transitions.
- Operating material: Deployment, tenant support, usage visibility and migration procedures.

## Should every customer have a separate database?

It depends on isolation requirements, operating cost and scale. Compare shared, partitioned and dedicated models with realistic support and migration scenarios.
