# SaaS development company > Infikey Technologies builds SaaS products: multi-tenant web and mobile applications with subscription billing, user onboarding, role-based access, admin consoles, integrations and analytics. We also modernise on-premise software into SaaS and add AI features to existing products. Typical SaaS MVPs cost USD 25,000–80,000, with larger platforms phased by release. Multi-tenant products with billing, onboarding and admin built in, on an architecture that stays fast and affordable as customers grow. - **MVP budget:** USD 25k–80k (INR 20–65 lakh) - **Architecture:** Multi-tenant, API-first, cloud native - **Billing:** Stripe, Razorpay, Chargebee, Paddle - **Cloud:** AWS, Azure, Google Cloud ## SaaS development services - **[Multi-tenant SaaS development](https://infikeytechnologies.com/industries/saas/multi-tenant-saas-development)**: tenant isolation, workspaces, roles, custom domains and per-tenant settings. - **[SaaS billing and subscription systems](https://infikeytechnologies.com/industries/saas/saas-billing-subscription-system)**: plans, trials, usage-based pricing, invoices, dunning and tax. - **MVP development** for founders validating a product, see our [MVP development](https://infikeytechnologies.com/industries/startups/mvp-development) guide. - **SaaS modernisation**: moving desktop or single-tenant software to a multi-tenant cloud product. - **AI features**: assistants grounded in customer data, summarisation, classification and automation, built with our [AI team](https://infikeytechnologies.com/services/ai). - **Integrations and APIs**: public APIs, webhooks, Zapier and native integrations with CRMs, accounting and communication tools. ## What every serious SaaS product needs | Area | What we build in | |---|---| | Accounts | Sign-up, SSO (Google, Microsoft, SAML), invitations, roles and permissions | | Tenancy | Data isolation, workspace switching, per-tenant configuration and limits | | Billing | Plans, trials, upgrades, usage metering, invoices, tax and failed-payment recovery | | Admin | Internal console for support, impersonation with audit, feature flags | | Security | Encryption, audit logs, rate limiting, backups, secrets management | | Observability | Error tracking, performance monitoring, uptime alerts, product analytics | | Compliance readiness | Controls that support SOC 2 and ISO 27001 audits, GDPR and DPDP data rights | ## SaaS development cost | Product | Budget (USD) | Budget (INR) | |---|---|---| | SaaS MVP with billing and admin | 25,000–50,000 | 20–40 lakh | | B2B SaaS with SSO, integrations and analytics | 50,000–120,000 | 40 lakh–1 crore | | Modernising on-premise software to SaaS | 40,000–150,000+ | 32 lakh–1.25 crore+ | | Ongoing product team (monthly) | 8,000–30,000 | 6.5–25 lakh | These are planning ranges, not quotes.

We often support both. - **Monolith first**: a well-structured modular monolith ships faster and costs less to run. Split into services when scale or team size demands it. See [monolith vs microservices](https://infikeytechnologies.com/compare/monolith-vs-microservices). - **Cloud costs**: autoscaling, caching and right-sized databases keep hosting a small share of revenue. - **Data residency**: hosting regions for India, the UAE, the UK, the EU and the US when customers require it. ## How we work with SaaS teams 1. **Discovery**: users, jobs to be done, pricing model and the smallest product that proves value. 2. **Design**: clickable prototype tested with target users. 3. **Build in sprints** with a working release every sprint and product analytics from day one. 4. **Launch** with monitoring, onboarding emails and support tooling. 5. **Grow** with a [dedicated product team](https://infikeytechnologies.com/industries/startups/dedicated-development-team) for features, performance and integrations. ## Frequently asked questions ### Who owns the SaaS code and IP? You do. Source code, designs and documentation are handed over in repositories you control, and we work under an NDA. ### Which tech stack do you use for SaaS? Commonly Laravel or Node.js on the back end, React or Next.js on the front end, PostgreSQL or MySQL, Redis, and AWS, Azure or Google Cloud. We choose based on your team, scale and hiring plans. ### Can you help us get SOC 2 or ISO 27001 ready? We build the technical controls auditors look for: access control, logging, encryption, backups, change management and vulnerability scanning. Certification itself is done by an independent auditor. ### Should we build multi-tenant from day one? Yes, in most cases. Adding tenancy later means touching every query and screen. A simple shared-database model is cheap to build at the start and keeps future options open. ## Related guides - [Multi-tenant SaaS development](https://infikeytechnologies.com/industries/saas/multi-tenant-saas-development): Multi-tenant SaaS development means building one application that serves many customer organisations (tenants) from shared infrastructure, w... - [SaaS billing and subscription system development](https://infikeytechnologies.com/industries/saas/saas-billing-subscription-system): A SaaS billing and subscription system manages plans, trials, upgrades and downgrades, seat and usage-based pricing, invoices, taxes, paymen... - [Software development company for startups](https://infikeytechnologies.com/industries/startups): Infikey Technologies helps startups build and scale software: MVPs for web and mobile, product design, dedicated engineering teams, AI featu... - [Monolith vs microservices: which architecture should you choose?](https://infikeytechnologies.com/compare/monolith-vs-microservices): A monolith is one application deployed as a single unit: simpler to build, test and run, and the right start for most products and small tea... - [AWS vs Azure vs Google Cloud: which cloud should you choose?](https://infikeytechnologies.com/compare/aws-vs-azure-vs-google-cloud): AWS has the widest range of services and the largest ecosystem, a safe default for most new products.
