Step-by-step guide to building a SaaS product in 2026, realistic timeline, team composition, tech stack choices, and cost ranges.

Building a SaaS in 2026 typically takes 8–16 weeks for an MVP and 6–9 months for a fully-featured product. Costs run $15,000 for a lean MVP to $200,000+ for an enterprise SaaS. Here's the playbook.

Full feature set, custom UI/UX, role-based access, analytics, integrations, advanced billing (subscriptions, usage-based). 2–3 developers + designer + QA.

Phase 3: Scale (ongoing, $80K–$200K+)

Multi-tenancy, SSO, audit logs, advanced security (SOC 2 prep), enterprise features, performance optimization, AI features. Full team including architect and PM.
