SaaS Development
We design and build multi-tenant software products — tenancy and identity, subscription billing, onboarding, admin tooling and the operational surface a SaaS business runs on.
What does SaaS development involve?
SaaS development is building software delivered as a subscription service to many customers from one codebase. Beyond product features it requires tenant isolation, authentication and role models, subscription billing, self-serve onboarding, usage metering, administrative tooling and an operational setup that supports continuous deployment without disrupting live customers.
The architectural decision that shapes everything else is the tenancy model — shared schema with row-level security, schema-per-tenant, or database-per-tenant. Each trades isolation against operational cost, and changing it later is expensive, so it is worth deciding deliberately at the start.
A SaaS product is not a web application with a login page. The moment a second customer arrives you own tenancy, data isolation, per-customer configuration, plan entitlements and a support surface. The moment the first invoice is issued you own billing correctness, proration and dunning.
We build these foundations early, because retrofitting them is where SaaS products stall. Then we keep the release path short: trunk-based development, migrations that run forward safely, feature flags for staged rollout, and telemetry that shows which customers are affected when something breaks.
Business problems
What this usually solves.
The situations clients describe when they start this conversation.
Tenancy bolted on after launch
A single-customer application grows a tenant column, and every query becomes a potential data leak because isolation lives in application code rather than the database.
Billing that drifts from entitlements
Plans in the billing provider and permissions in the application are maintained separately, so customers get access they have not paid for, or lose access they have.
Onboarding that requires the founder
Every new customer needs manual setup, which caps growth at the number of accounts the team can hand-configure.
Releases that need a maintenance window
Schema changes are breaking and deployments are risky, so shipping slows to a monthly cadence and the backlog grows.
Capabilities
What we bring to it.
Tenancy architecture
Isolation modelled at the database layer with row-level security or separate schemas, so a missing filter in application code cannot cross tenants.
Identity and access
Organisations, roles, invitations, delegated administration and enterprise SSO through Microsoft Entra ID or SAML when customers require it.
Subscription billing
Stripe-backed plans, trials, proration, usage metering and webhook reconciliation, with entitlements derived from subscription state rather than duplicated.
Self-serve onboarding
Signup, workspace provisioning, data import and guided first-run so a customer reaches value without a human on your side.
Admin and support tooling
Internal consoles for impersonation, plan changes, audit history and diagnostics — the tooling that makes support sustainable.
Release engineering
CI pipelines, forward-safe migrations, feature flags, staged rollout and error budgets that let you ship weekly without drama.
Deliverables
What we build
- New SaaS products taken from concept to first paying customers
- Multi-tenant rebuilds of software currently deployed per customer
- Enterprise tiers with SSO, audit logs and granular role models
- Usage-based and hybrid billing models with metering pipelines
- Partner and reseller portals layered over an existing platform
- White-label deployments with per-tenant branding and configuration
Stack
Technology approach
We favour boring, well-understood infrastructure for the parts that must not fail, and spend the novelty budget on the product itself.
| Layer | What we use |
|---|---|
| Application | Next.js App Router with server components and server actions |
| API | Typed REST or tRPC-style contracts, versioned for external consumers |
| Data | PostgreSQL with row-level security, migrations in version control |
| Identity | Session or token auth, Microsoft Entra ID and SAML for enterprise tiers |
| Billing | Stripe subscriptions, metering and webhook reconciliation |
| Platform | Azure or AWS, infrastructure as code, preview environments per branch |

FAQ
SaaS Development — questions we are asked
Which multi-tenancy model should we use?
Shared schema with row-level security suits most products: one migration path, efficient resource use, isolation enforced by the database. Database-per-tenant is worth the operational cost when customers demand physical separation or regional data residency. We decide this in architecture, before the first table is created.
Can you take over an existing SaaS codebase?
Yes. We start with a review of the tenancy model, data access paths, deployment pipeline and test coverage, then propose a sequence that addresses risk first and feature work second.
How do you handle billing edge cases?
Subscription state lives in the billing provider and is mirrored into the application through verified webhooks with replay handling. Entitlements are computed from that state, never stored twice. Proration, downgrades and failed payments are handled as explicit states rather than special cases.
Do we need enterprise SSO from day one?
Usually not, but the identity model should anticipate it. If organisations, roles and invitations are modelled properly, adding Entra ID or SAML later is an integration rather than a redesign.
