SaaS Product Development
Multi-tenant products with the billing, onboarding and release discipline a subscription business depends on.
Overview
A subscription product is one codebase serving tenants who do not share a release window. The decisions that are expensive to reverse are made first: the tenancy model, the billing and entitlement rules, and the path that ships a change to one tenant before the rest. A business needs this when the product is sold by subscription rather than handed over once.
- Tenancy model and data isolation
- Plans, entitlements and usage metering
- Subscription billing, invoicing and failed payments
- Sign-up, workspace creation and role invitations
- Single sign-on and enterprise provisioning
- Feature flags and staged tenant rollout
- Admin console and per-tenant support tooling
What you receive
- 01A running multi-tenant product, with the isolation between tenants covered by tests in the pipeline.
- 02A billing integration that reconciles with the payment provider, and invoices that meet local e-invoicing requirements.
- 03An onboarding path from sign-up to a working workspace, including invitations, roles and single sign-on.
- 04A deployment pipeline that runs schema migrations without taking the product down, with flags and a staged rollout per tenant.
- 05An admin console where support can find a tenant, change its plan and read an audit log of who changed what.
- 06A written record of the tenancy, billing and migration decisions, kept in the repository with the code.

How the engagement runs
The tenancy model is decided first. Everything after it inherits the answer: how tenants are separated in the database, what a shared record looks like, and what happens when one tenant asks for its data back. Billing is built against that model, not beside it, so a plan change, an expiring trial and a failed payment all move the same entitlement. Onboarding and the admin console are built as product, not as internal screens. Release runs behind flags, so a change can be turned off for one tenant without a deploy. After launch the team stays on the repository, through the first renewals, the first upgrades and the first ticket the design did not anticipate.
- A new tenant can be signed up, billed and supported without an engineer in the loop.
- A plan or a price can change without editing the code that grants access.
- A release can reach one tenant first, and be pulled back without a restore.
- What a tenant costs to run is visible in the same place as what it pays.
