A B2B SaaS billing platform

Migrated a single-tenant Rails app to a multi-tenant Laravel platform without a downtime cutover.

Result

Onboarding time

< 10 min

↓ from 2 weeks

Infra cost per tenant

−62%

vs. per-tenant DB

Challenge

The client had outgrown a single-tenant architecture — every new customer meant a new database and a new deploy. Onboarding took two weeks of engineering time per customer.

Approach

Designed a schema-per-tenant Postgres architecture with a shared application layer, then migrated existing customers in batches using a dual-write strategy during the transition window.

Outcome

New customer onboarding dropped from a two-week engineering task to a self-service signup flow.
