SaaS MVP Costs at $35-$45/hr: TypeScript & Headless CMS

Cost Breakdown: Building a SaaS with a $35-$45/hr Team

At $35-$45 per engineering hour, a focused team can ship an enterprise-grade SaaS MVP without runway panic. Here's a pragmatic cost model across phases, with specific choices around TypeScript migration and best practices, fullstack engineering services, and Headless CMS integration (Contentful, Strapi). We'll keep the math honest.

Team shape and weekly burn

A lean, senior-leaning pod delivers the best price-to-velocity ratio:

Tech Lead (fullstack, TypeScript/Node/React): 20 hrs/week
Fullstack Engineer: 30 hrs/week
Frontend Engineer: 20 hrs/week
Backend/DevOps Engineer: 15 hrs/week
QA Engineer: 10 hrs/week

Total: 95 hrs/week. At $35/hr the burn is $3,325; at $45/hr it's $4,275. This pod routinely ships a production MVP in 10-12 weeks.

Phase 1: Discovery and architecture (week 1, 60-80 hrs)

Deliverables: lean PRD, event storming, ERD, API surface, risk register.
Stack: Next.js + React, Node/NestJS, PostgreSQL, Redis, OpenAPI, Turbo monorepo.
Cost: $2.1k-$3.6k. Goal: decide build vs buy for auth, billing, messaging, and CMS.

Phase 2: Foundations with TypeScript-first (weeks 2-3, 160-200 hrs)

TypeScript migration and best practices applied from day one: strict mode, eslint, ts-prune, path aliases, DTOs, Zod validation at boundaries.
Automations: CI/CD, commit hooks, preview deployments, storybook for design system.
Cost: $5.6k-$9k. Savings: fewer regressions and faster onboarding later.

Phase 3: Core platform (weeks 3-6, 300-360 hrs)

Auth and RBAC: OAuth/SAML via Auth0 or Ory; audit log; org/user/role models.
Billing: Stripe metered subscriptions; entitlement checks in middleware.
Data: Postgres schemas, Prisma migrations, background jobs with BullMQ.
Cost: $10.5k-$16.2k depending on integrations and compliance.

Headless CMS integration: Contentful vs Strapi (weeks 5-7, 80-120 hrs)

Contentful: faster to production, robust localization, higher SaaS fees; 40-60 hrs to model content, webhooks, and role-based editorial flows.
Strapi: self-hosted control, lower vendor fees, more DevOps; 60-80 hrs including containerization, backup, and SSO.
Cost: $2.8k-$5.4k. Choose based on editorial complexity and compliance posture.

QA, security, and performance hardening (weeks 6-9, 160-220 hrs)

Testing: unit tests for services, Playwright for e2e, contract tests for APIs.
Security: OWASP review, dependency scanning, secrets rotation, rate limits.
Perf: CDN tuning, DB indexes, N+1 audits, synthetic monitoring.
Cost: $5.6k-$9.9k.

Sample 12-week MVP budget

At 95 hrs/week, a 12-week run consumes ~1,140 hours. Budget ranges:

Low (at $35/hr, lighter CMS and auth): ~$39,900
Mid (mix of Contentful, Auth0, analytics): ~$44,000-$47,000
High (heavier SSO, Strapi self-hosting, more QA): ~$51,000

These include infrastructure setup (Terraform, Vercel/CloudFront, Kubernetes if needed), observability (Grafana, Sentry), and compliance-ready logging.

Migrating an existing JS MVP to TypeScript

If you already have a JavaScript MVP, plan a two-track TypeScript migration:

Week 1: add tsconfig with strict settings, bootstrap types on shared models, introduce Zod schemas, ship d.ts shims to unblock compilation.
Weeks 2-4: migrate hot paths first (billing, auth, data layer). Wrap legacy modules with interface adapters; use incremental ts-jest coverage gates.
Weeks 5-6: refactor rough edges, kill any-any types, enforce eslint rules in CI.

Cost: 180-240 hrs, or $6.3k-$10.8k. Expect defect rate to drop by 30-50% and onboarding time to shrink by a week per engineer.

Where fullstack engineering services pay for themselves

Vertical slices: one engineer owns API, DB, and UI for a feature, reducing handoffs.
Contract-first APIs: OpenAPI drives server and client generation, eliminating drift.
Design system: tokenized theming accelerates enterprise white-label deals.

Hidden costs to budget for

Multi-tenant isolation tests and data export tooling.
Incident runbooks and on-call rotation readiness.
Analytics and attribution (PostHog, Segment) and privacy impact assessments.

Choosing your partner

If you want vetted talent without recruiting drag, slashdev.io provides excellent remote engineers and software agency expertise for business owners and startups to realize their ideas. Expect curated pods, predictable delivery, and clear burn tracking.

Enterprise add-ons and timelines

SSO expansion (Okta, Azure AD) adds 40-60 hours, mostly mapping claims and SCIM provisioning. SOC 2 readiness typically requires 30-50 hours to set up policies, logging, and evidence collection, excluding audit fees. For data residency, budget 24-36 hours to provision a regional database, tune backups, and update routing rules.

Practical cost controls

Timebox experiments: 8-12 hours to validate a library, then decide.
Adopt a "buy unless strategic" rule for auth, billing, and CMS.
Freeze scope weekly; ship value every Friday behind feature flags.
Keep environments minimal: prod, staging, ephemeral PRs only when necessary.
Instrument everything early; measure latency and error budgets from week two.

Document decisions relentlessly; ambiguity is the most expensive line item during delivery.

The headline: with disciplined TypeScript practices, judicious Headless CMS integration, and a senior-biased fullstack team, a credible SaaS MVP lands in three months for roughly $40k-$51k at $35-$45/hr-positioned to scale, demo, and sell.
