SaaS products combine recurring revenue mechanics with deep workflow software. Cost depends on tenant model, billing complexity, integrations and how many personas you serve on day one. This guide outlines typical bands for India-based product engineering in 2026.
All ranges below are illustrative — owner approval required. Your scoped estimate will define modules, tenant strategy, timeline and exclusions.
Currency and Market Assumptions
- Primary currency: USD proposals; INR available for Indian entities
- Delivery: India-based product engineering teams for global B2B and B2C SaaS
- Architecture baseline: Cloud-native on AWS (or equivalent), managed auth and Stripe-style billing hooks where applicable
- Team tier: Senior-led squad with discovery, not junior offshore body-shop rates
- Excluded: Stripe/payment processing fees, email/SMS usage, SOC2 audit fees, legal terms drafting
Included and Excluded Scope
Typically included:
- Discovery, user flows and technical architecture document
- Web application (responsive) for primary user persona
- Admin / operations panel for internal or customer-admin roles
- Authentication, roles and basic tenant isolation
- Core workflow modules agreed in scope
- QA, staging environment, production deployment
- 30–90 day post-launch defect support
Typically excluded unless scoped:
- Full SOC2 certification program and third-party audits
- Custom usage-based metering engines
- White-label per-tenant theming at scale
- Mobile native apps (often phase 2)
- Data migration from legacy systems
- Ongoing feature squads and 24/7 on-call
Typical SaaS Modules
| Module | Description | MVP? |
|---|---|---|
| Auth & org onboarding | Signup, invites, roles, password reset | Core |
| Tenant / workspace model | Single-tenant MVP or multi-tenant from day one | Architecture decision |
| Core product workflows | Primary value screens and APIs | Core |
| Subscription billing | Stripe Checkout, plans, webhooks | Often MVP |
| Admin dashboard | Users, settings, support tools | Light MVP |
| Notifications | Email, in-app; SMS optional | Email in MVP |
| Reporting & exports | CSV, dashboards, scheduled reports | Phase 2 |
| Integrations | CRM, webhooks, OAuth apps | 1–2 in MVP max |
| Audit & compliance logs | Immutable activity trail | Phase 2 / enterprise |
| SSO (SAML/OIDC) | Enterprise login | Enterprise phase |
Team Composition
- Product / project lead — roadmap, milestones, stakeholder sync
- UI/UX designer — design system or component library alignment
- 2× full-stack or backend-heavy engineers — API, data model, integrations
- Frontend engineer — when UI complexity warrants dedicated focus
- QA engineer — regression on billing and permission paths
- DevOps — CI/CD, environments, monitoring baseline
Enterprise SaaS adds a tech lead, security review cycles and dedicated QA automation.
Typical Timeline
| Phase | Duration | Output |
|---|---|---|
| Discovery & architecture | 2–4 weeks | Scope, data model, tenant strategy |
| Design | 2–4 weeks | UI flows, component specs |
| MVP engineering | 10–18 weeks | Core workflows, auth, billing hook |
| QA & launch | 2–4 weeks | Production release, runbook |
Focused single-persona MVPs often land in 4–6 months; multi-module B2B SaaS can run 6–10 months.
Illustrative Cost Ranges
Illustrative — owner approval required.
| SaaS type | Typical range (USD) | Notes |
|---|---|---|
| Single-tenant B2B tool MVP | $30k – $55k | One org model, limited roles |
| Multi-tenant SaaS MVP | $35k – $80k | Tenant isolation, billing, admin |
| B2B SaaS with integrations | $60k – $120k | 2–4 integrations, webhooks |
| Production multi-tenant platform | $80k – $200k+ | SSO-ready, audit, scale hardening |
| Enterprise + mobile companion | $120k – $280k+ | Web + iOS/Android apps |
| Post-MVP hardening | +40–80% | Tests, observability, compliance prep |
Cost Factors
- Tenant model — row-level multi-tenancy vs separate DBs vs hybrid
- Billing complexity — flat plans vs seats vs usage metering
- Permission matrix — coarse roles vs granular RBAC/ABAC
- Workflow depth — states, approvals, document generation
- Real-time features — live collaboration, websockets, notifications at scale
- Integration count — each partner adds mapping, retries and admin tooling
- Compliance target — SOC2-ready architecture vs checkbox MVP
Hosting and Maintenance
- AWS infrastructure — $300 – $2,500+/month for early-stage SaaS; scales with tenants and traffic
- Managed services — RDS, Cognito/Auth0, Stripe, SendGrid billed separately
- DevOps retainer — $2,000 – $8,000+/month for CI/CD, monitoring, incident response
- Product squad retainer — $5,000 – $20,000+/month for ongoing roadmap delivery
- Security patches — dependency and framework updates included in retainer
Phased MVP Approach
Phase 1 — Prove value: Single primary persona, one pricing plan, core workflow end-to-end, email auth, lightweight admin. Manual workarounds acceptable for edge cases.
Phase 2 — Grow: Additional roles, self-serve billing upgrades, integrations, in-app notifications, export/reporting.
Phase 3 — Enterprise: SSO, audit logs, SLA tooling, performance at scale, advanced admin and API for partners.
We design tenant and billing boundaries in Phase 1 so Phase 2 does not require a rewrite.
Frequently Asked Questions
If you sell to multiple customers on one deployment, yes — retrofitting tenancy later is expensive. Single-enterprise pilots can start single-tenant with a clear migration path.
Basic subscription checkout and webhook handling is commonly in MVP scope. Usage-based metering, invoicing quirks and multi-currency often add a phase or change order.
Engineering patterns (logging, access control, encryption) can be baked in early. Formal SOC2 audit programs are separate vendor and legal costs — typically tens of thousands USD annually.
