Frequently Asked Questions

Everything you need
to know before hiring.

How do you handle multi-tenancy?
Three patterns: (1) row-level isolation (tenant_id + Postgres RLS) for most B2B SaaS — cheap, scales to 10k+ tenants; (2) schema-per-tenant for compliance-heavy workloads; (3) database-per-tenant for enterprise tier or strict data residency. We pick based on your tier mix and compliance needs.
What about billing — Stripe, Chargebee, Paddle?
Stripe Billing for most SaaS (best webhooks, best metered billing). Chargebee when you need quote-to-cash + heavy invoicing. Paddle as MoR if you want to outsource sales tax + VAT. Lago if you want open-source. We integrate any of them properly — including dunning, recovery, tax, and proration.
How do you build for SOC 2 from day 1?
Vanta or Drata from week 1. Audit logs append-only on every state change. RBAC + just-in-time access. Encryption at rest and in transit. Backup + DR drills. Change management via PR. SOC 2 evidence is a side-effect of how we build, not a separate audit project.
What about enterprise readiness — SSO, SCIM, audit?
Standard. SAML SSO + OIDC via WorkOS / Auth0 / Clerk. SCIM provisioning. Audit log API + streaming to customer SIEM (Snowflake, BigQuery). RBAC + per-tenant roles. Org + team + role data model from the start.
How do you handle feature flags + plan gating?
LaunchDarkly / Statsig / Flagsmith / PostHog. Plan-based gating tied to subscription tier (free/pro/enterprise). Cohort + segment targeting. Experimentation framework so growth + product can ship safely.
What does the 14-day SLA actually mean?
From discovery (day 1) to a SaaS developer onboarded and shipping their first multi-tenancy-aware PR by day 14.
How does the replacement guarantee work?
5 business days notice, 2-3 replacement profiles within 48 hours.
How do you vet SaaS developers?
5 steps: resume + product portfolio screen, technical screen with our SaaS architect, live coding test (90 min) building a multi-tenant feature + Stripe webhook handler with idempotency, system-design round (60 min) on tenancy isolation + RBAC + audit log + billing model, culture-fit + references.
