SaaS Application Development

Multi-tenant from the schema up, not bolted on later.

SaaS application development covering multi-tenancy, billing integration, and the operational groundwork a subscription product needs before its first paying customer.

THE BUSINESS NEED

Start with the problem.
Build what matters.

Retrofitting multi-tenancy, billing, and tenant-level data isolation into a product built as a single-customer application is expensive and risky. A SaaS product needs those decisions made early — how tenants are isolated, how billing state stays consistent with access control, and how one tenant's load or bug can't affect another's.

How we approach it

We choose a tenancy model based on your actual isolation, scaling, and compliance requirements — not a default — and make sure authorization checks enforce tenant boundaries at the data access layer, not just in the UI. Billing state (what a tenant is entitled to) is kept as a single source of truth that authorization logic reads from directly, so a failed webhook can't silently leave access out of sync with payment status.

CAPABILITY IN DETAIL

What this means in practice.

Specific engineering work, connected to a business need.

01

Multi-tenant architecture

Design and implement the tenancy model — shared schema with tenant IDs, schema-per-tenant, or full database-per-tenant — matched to your isolation and scaling requirements.

02

Billing and subscription logic

Integrate subscription billing with plan upgrades, downgrades, proration, and failed-payment handling, keeping billing state and product access consistent.

03

Tenant-scoped authorization

Enforce data isolation at the query and API layer so a bug in the interface can't expose one tenant's data to another.

04

Operational tooling

Build internal admin tools for tenant management, impersonation for support purposes, and usage visibility needed to actually run a SaaS business.

WHERE IT CAN HELP

Problems worth solving.

Illustrative engagement types, not claims about previous projects.

  • Turning a single-customer application into a genuine multi-tenant product
  • Adding subscription billing with proration and plan changes to an existing product
  • Auditing and hardening tenant isolation before a compliance review or enterprise customer

BEFORE WE BEGIN

Questions, answered.

Which tenancy model do you recommend?

It depends on your isolation and compliance needs and expected scale. Shared schema with row-level tenant scoping is simplest to operate; database-per-tenant gives the strongest isolation at higher operational cost. We walk through the trade-off with you rather than defaulting to one.

Can you add multi-tenancy to our existing single-tenant product?

Yes, this is a common engagement. It requires careful migration planning so existing customer data is correctly scoped without downtime or data loss.

Do you integrate with a specific billing provider?

We typically integrate with established billing providers like Stripe rather than building payment processing from scratch, and design the integration so billing state stays the source of truth for access control.
