Sector — SaaS & Platform
Multi-tenant platforms, billing, and developer surfaces built for compounding scale.
Summary
SaaS and platform businesses live on three pieces of software working together: a clean multi-tenant data model, a billing system that is never wrong, and a developer surface — API, SDKs, docs — that engineers actually want to integrate. Get any of the three wrong and growth arrives as support load and churn rather than revenue.
Polyric works with SaaS and platform teams from early products hardening for their first enterprise customers through established platforms launching new product lines. We build the foundation — tenancy, billing and metering, RBAC, API surface, admin and audit — so the product team ships features instead of fighting the architecture.
What this sector demands
The constraints saas & platform software lives under.
We map each requirement to the engineering decision that satisfies it — so the system that ships actually meets the constraint.
Need · 01
Clean multi-tenancy
Strict tenant isolation in the database and the application — no accidental cross-tenant reads, ever.
How we deliver
Postgres RLS-based tenancy
Tenant isolation enforced at the database, not just the app — defensible to auditors and to engineers in a hurry.
Need · 02
Billing that matches reality
Usage metering, plan changes, proration, and dunning that finance, sales, and customers all agree on.
How we deliver
Metering and billing integration
Usage metering and webhook handling that survives retries, out-of-order events, and plan migrations.
Need · 03
First-class developer surface
Versioned API, typed SDKs, accurate docs, and a stable webhook contract.
How we deliver
OpenAPI-first API design
Typed SDKs generated from the spec, docs derived from the same source, no drift.
Need · 04
Self-serve admin controls
Customer admins managing roles, SSO, audit logs, and billing without filing a support ticket.
How we deliver
Admin and audit surfaces
Admin console with role management, audit logs, SSO via SAML / OIDC, and SCIM provisioning when you need it.
Need · 05
Observable scale
Per-tenant metrics so you can spot the customer breaking your platform before they email.
How we deliver
Per-tenant observability
Tenant-tagged metrics and traces so support, ops, and engineering see the same picture.
Example systems
What we typically build here.
- Greenfield SaaS platform foundations
- Billing and metering re-platforming
- Public APIs and developer portals
- Enterprise-readiness work (SSO, audit, RBAC)
