⏚ Summary
What this engagement is, plainly.
SaaS is easy until tenant 100. We architect tenancy, billing, identity, and feature gating in the first sprint so the boring problems stay boring as you grow.
Problems we solve
You're about to commit to a SaaS architecture and want the seams set right before they ossify.
Your existing single-tenant app needs to become multi-tenant and you're not sure where to draw the lines.
Billing, plans, and entitlements are tangled across your codebase.
⏚ Approach
How we run this engagement.
- 01Phase
Tenancy model
Pooled, siloed, or hybrid — chosen on compliance, scale, and unit economics. Most SaaS gets this wrong by defaulting; we make it a decision.
- 02Phase
Entitlements as a system
Plans, features, usage limits — modeled in one place with a typed runtime. Marketing pages and product code share one source of truth.
- 03Phase
Operate the seams
Self-serve onboarding, audit logs, admin tooling, billing reconciliation. The seams between product and operations that decide whether you scale headcount linearly with customers.
⏚ Deliverables
What you get, signed off.
Tenancy + data isolation design
Entitlements system + admin console
Billing integration (Stripe / Paddle) with reconciliation
Self-serve onboarding flow
Audit logging + observability per tenant
⏚ Stack we typically use
Tools, not religion.
We pick on workload and team shape, not on fashion. Anything below is a default — swappable when your context demands.
- TypeScript
- Next.js
- Postgres
- Stripe
- Clerk
- Trigger.dev
Outcome
A SaaS where adding tenants doesn't add work, entitlements aren't a maintenance burden, and billing reconciliation is a query — not a fire drill.
