B2B SaaS Billing Ops Stack
This is the stack for B2B SaaS teams that outgrow simple checkout flows. Billing automation, invoices, lifecycle email, analytics, and your product database all stay connected.
Fresh stack
Loading
A backend API that handles production traffic without a major architectural rewrite as you grow — connection-pooled Postgres, Redis job queues, containerized deployments, and managed hosting that's simpler than AWS.
Workflow stack
The order matters. Start at the top, read down the sequence, and open any step when you want the note behind it.
Primary database
Relational database for structured business data — ACID transactions, complex queries, and foreign key constraints that catch data integrity issues at the database level.
Open tool profileORM and migrations
Schema-first ORM that generates TypeScript types from your database schema — migrate with confidence and never write raw SQL for standard CRUD operations.
Open tool profileCache and queues
In-memory store for session caching, rate limiting counters, and BullMQ background job queues — keeps expensive operations out of the synchronous request path.
Open tool profileContainerization
Package the Node app with its exact dependencies so the same container runs in development, CI, and production — no more environment-specific bugs.
Open tool profileManaged deployment
One-command deployments with managed Postgres and Redis instances, automatic SSL, and environment variable management — simpler than ECS without giving up flexibility.
Open tool profileTools in this stack
Open any tool profile if you want pricing, fit, or comparison details.
JavaScript runtime for servers, APIs, CLIs, and tooling with an event driven model and broad ecosystem.
