US SaaS founders who successfully close their first 10 customers manually and are ready to scale hit the same three architectural walls: no multi-tenant isolation, no admin panel, and no SOC 2 — all three are faster and cheaper to build before you have 100 customers than after

The right multi-tenant architecture for most US SaaS products is a shared-database, shared-schema model with row-level security in PostgreSQL enforcing tenant isolation at the query level. This approach provides strong tenant isolation without the operational complexity and cost of schema-per-tenant or database-per-tenant architectures. Each table that contains tenant-scoped data includes a tenant identifier column. PostgreSQL row-level security policies ensure that queries from one tenant cannot return rows belonging to another tenant. The tenant context is set at the connection level at the start of every request using a middleware or database session variable. This architecture should be implemented from the first database migration; retrofitting it into an existing single-tenant schema requires touching every table and every query in the application, which is a high-risk operation on a live production database.

SOC 2 Type II requires a minimum observation period of six months, during which the auditor collects evidence that the controls documented in the SOC 2 report are operating effectively. The process starts with a SOC 2 readiness assessment to identify gaps between the current control environment and the required controls, followed by implementing the missing controls, then the observation period, then the audit itself. From the start of the readiness assessment to the issuance of the SOC 2 Type II report is typically 9-14 months. A US SaaS company should start the SOC 2 process when it begins active enterprise outreach, not after the first enterprise deal requires the report. The most efficient approach is to implement the required engineering controls (access control, audit logging, encryption, change management, monitoring) as part of the initial product build rather than as a post-launch remediation project.

HIPAA compliance for a US SaaS product requires six concrete actions: signing a Business Associate Agreement with AWS (or the hosting provider) and enabling HIPAA-eligible AWS services for all services that handle PHI; executing BAAs with any other subcontractor that handles PHI including database providers, logging services, and third-party APIs; implementing technical safeguards including encryption at rest for PHI, encryption in transit for all PHI transmission, access controls limiting PHI access to authorised users, and audit logging of all PHI access and modification events; creating and maintaining the required HIPAA policies and procedures including the Privacy Policy, Security Rule Risk Analysis, and Workforce Training programme; executing a Business Associate Agreement with each covered entity customer before they upload any PHI to the product; and conducting an annual HIPAA Security Rule risk analysis as required by the Security Rule. HIPAA is a continuing obligation with annual requirements, not a one-time certification.

Stripe Billing integration for a SaaS product follows a subscription object model: Products and Prices are created in Stripe representing the SaaS plans, a Stripe Customer object is created for each customer at signup, a Subscription is created for each customer when they select a plan, and the SaaS product listens to Stripe webhook events to keep its local subscription state in sync with Stripe's authoritative subscription state. Trial periods are configured on the Price or at the Subscription level with a trial end date. Dunning is configured via Stripe's Smart Retries and the Stripe Customer Portal, which handles failed payment retry notifications automatically. Proration for plan upgrades and downgrades is handled by Stripe automatically when the Subscription is updated. The SaaS product should never attempt to calculate proration manually; it should update the Stripe Subscription and consume the resulting invoice events from the webhook stream.

Building a US SaaS product with an offshore engineering team requires four process disciplines that most offshore engagements lack: a product scoping process that produces written acceptance criteria for every feature before it is built, so that done means done and scope creep is caught at the sprint planning stage rather than during sprint review; architecture decision records (ADRs) written in English documenting every significant architectural choice and the reasoning behind it, so the founding team can participate in architectural decisions rather than having them made opaquely; a code review process with the founding team (or a US-based senior engineer they designate) reviewing pull requests for at least the first 60 days, so the code quality standard is established by example and not assumed; and a sprint cadence with synchronous sprint reviews at a time that works for both US and Nepal/India time zones. Ignited Nepal operates with all four of these disciplines as non-negotiable engagement requirements.
