The checklist
Tick an item only when it is true in production today, not when it is planned. Your ticks are kept in this browser only and are included when you copy or download the checklist.
It is one of several planning resources in our free tools library.

How to use this checklist
Run this checklist as a working session, not a solo exercise. Put the tech lead, whoever runs infrastructure, someone responsible for security and a product owner in the same room for 90 minutes. Go section by section and tick an item only when someone can show the evidence — a test, a dashboard, a runbook, a config file. “We could do that quickly” is an unticked item.
Unticked items are not automatically problems. A pre-revenue product does not need SCIM provisioning or a single-tenant restore procedure. For each gap, score impact and likelihood, and note the trigger that would make it urgent, such as “first enterprise prospect asks for SSO” or “largest tenant exceeds 10% of database load”. Put the top five to ten into your roadmap with owners and dates.
Tenancy and data isolation deserve the most scrutiny because they are the hardest to change later. Our engineering article on multi-tenant data isolation in PostgreSQL compares shared-schema, schema-per-tenant and database-per-tenant designs, including row-level security; the broader multi-tenant SaaS architecture guide covers the product-level decisions around it. For scalability, observability and DR, the AWS reference architecture for high-traffic SaaS shows how these items fit together, and our CI/CD and automated testing pipeline article covers the delivery section in depth.

Tips from our delivery team
- Test isolation like an attacker. Automated cross-tenant tests catch the class of bug that ends SaaS businesses. They are cheap to write and should run on every build.
- Do not build SSO and billing from scratch. Mature identity and billing providers handle edge cases — SAML quirks, proration, tax — that take months to get right in-house.
- A backup you have never restored is a hope, not a backup. Time a restore, compare it with your RTO, and write down what surprised you.
- Know your cost per tenant. Pricing that does not cover infrastructure, third-party APIs and support for heavy tenants is a scaling problem disguised as growth.
- Collect compliance evidence as you go. Pull request reviews, access reviews and incident records created now make a later SOC 2 audit far less painful.
If you are planning a new product rather than reviewing an existing one, read about our SaaS application development approach and try the SaaS development cost calculator for an indicative budget.
Frequently asked questions
What is a SaaS architecture checklist used for?
It is a structured review of whether a SaaS product is ready for production scale and enterprise customers. Teams use it before launch, before large sales deals or security questionnaires, during due diligence, and quarterly to track architectural gaps.
Which items matter most for an early-stage SaaS product?
Tenant data isolation, secure authentication, secrets management, automated backups with a tested restore, basic observability and automated deploys. These are hard or dangerous to add later. Enterprise features such as SCIM, data residency and SOC 2 evidence can usually follow real customer demand.
Should each tenant get its own database?
Not by default. A shared schema with enforced tenant IDs, often with PostgreSQL row-level security, is simpler and cheaper for many tenants. Database per tenant gives stronger isolation and easier per-tenant restore but raises operational cost, so many products use shared storage by default and dedicated databases for large or regulated tenants.
Is this checklist enough to pass a SOC 2 audit?
No. It covers architecture and engineering practices that support SOC 2 readiness, but SOC 2 also requires documented policies, HR and vendor processes and an independent auditor. Use the compliance section to spot technical gaps early, then work with a qualified auditor.
