- Common Questions

FAQ

We design the tenancy model during scoping based on your compliance needs and scale targets. For most B2B SaaS, we use a shared Postgres schema with row-level security (tenant_id column on every table). For regulated industries (healthcare, finance), we implement fully isolated schemas or separate databases per tenant - with automated provisioning built in.

Yes - we build billing with this in mind from day one. Stripe's billing APIs support flat-rate, per-seat, usage-based, and hybrid models. We architect the integration so you can switch or combine models without touching backend logic. We also build metering infrastructure from the start if usage-based pricing is on the roadmap.

MVP (Weeks 3-12) is about proving value and getting to first revenue fast - core user journey, auth, billing, and onboarding. Scale (Week 16+) is about hardening: multi-tenancy enforcement, enterprise SSO, SOC 2 readiness, performance at 10× the user load, and growth loop mechanics. We never over-engineer in MVP phase - that's intentional.

Fully and completely. All source code, IP, and assets are yours from day one. We work in your GitHub repository (or set one up for you). There are no licensing fees, no lock-in, and no ongoing dependency on us to run the product.

We build with GDPR in mind: data deletion flows, consent management, audit logs, and data processing agreements. For EU data residency, we deploy on EU-region AWS or GCP infrastructure. For healthcare clients, we implement HIPAA-compliant architecture (encryption at rest + in transit, access controls, audit trails) at no extra architecture cost.

Yes - integration is a standard part of how we build. We connect to CRMs (HubSpot, Salesforce), support tools (Intercom, Zendesk), communication (Slack, Teams), and analytics (Segment, Amplitude) via webhooks and official SDKs. We also build internal webhook infrastructure so your SaaS can push events to any external tool.

That's entirely your call. Many clients retain us on a monthly engineering sprint after MVP - iterating on the product based on user feedback. Others take the codebase in-house with their own team. We provide a full handover documentation pack, architecture diagrams, and a deploy runbook regardless. We're a long-term partner, not a vendor who disappears.
