SaaS development cost depends on tenant model, billing complexity, integrations and how many personas you serve on day one. KodeBuilder does not use a one-size-fits-all price. We help small and growing businesses define the smallest useful first phase, identify what can wait and receive a written estimate before development begins.
This guide explains modules, team composition and what typically changes the estimate. KodeBuilder does not publish a custom-development rate card. After discovery we send a written estimate with modules, tenant strategy, timeline and exclusions. For delivery, see our SaaS development company service. Compare how quotes differ on the cost planning hub.
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 model: Senior-led product studio — discovery included, dedicated QA and DevOps
- 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.
What typically changes the estimate
Estimates follow scope, not a published rate card. Most SaaS products start in one of three planning phases. We confirm the right starting point during discovery and send a written estimate before development begins.
| SaaS type | Usual planning phase | What typically drives effort |
|---|---|---|
| Single-tenant B2B tool | Focused first phase | One org model, limited roles |
| Multi-tenant SaaS | Focused first phase or Business MVP | Tenant isolation, billing, admin |
| B2B SaaS with integrations | Business MVP | A few integrations, webhooks |
| Production multi-tenant platform | Full operational platform | SSO-ready, audit, scale hardening |
| Enterprise + mobile companion | Full operational platform | Web plus iOS/Android apps |
| Post-launch hardening | Full operational platform | Tests, observability, compliance prep |
Focused first phase proves one persona and one pricing path. Business MVP adds billing, extra roles and a small integration set. Full operational platform adds SSO, audit, scale and often mobile. See SaaS development for how KodeBuilder delivers these phases.
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 — billed by AWS and grows with tenants, traffic and redundancy
- Managed services — RDS, Cognito/Auth0, Stripe, SendGrid billed separately by those vendors
- DevOps and product retainers — quoted separately after launch for CI/CD, monitoring, incidents and roadmap work
- Security patches — dependency and framework updates included in a maintenance agreement
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, not part of a KodeBuilder build quote.
