Do you build the billing integration, or just the application?

Both, when it's in scope. Billing is treated as core product work, not a separate add-on, because pricing and plan structure usually affect the data model.

Can you migrate an existing single-tenant app to multi-tenant?

Yes. We audit the existing schema, plan a tenant-isolation strategy that fits your compliance requirements, and migrate incrementally where possible to avoid downtime.

SaaS Development

We build multi-tenant SaaS products end to end — data architecture, authentication and authorization, billing, and the application itself — with tenant-isolation and scaling decisions made deliberately at the start, not retrofitted after the first enterprise customer asks for it.

Common problems

Multi-tenancy gets bolted on after launch, requiring a painful data-model migration.
Billing integration is treated as an afterthought instead of a core product surface.
Authorization logic is scattered across the codebase instead of centralized and auditable.
Single-tenant assumptions leak into the database schema and can't be undone cheaply.

What you get

Tenant isolation designed into the data model from the first migration.
Billing (subscriptions, usage-based pricing, upgrades and downgrades) integrated as a first-class feature.
Centralized authorization logic that's auditable and consistent across the app.
Architecture that scales from first customer to enterprise without a rebuild.
