Custom SaaS development — from idea to production
SaaS (Software as a Service) is software delivered via subscription over the internet — a single application serving multiple customers, each on their own plan, each with their data kept completely separate. Building a SaaS product requires architectural decisions that standard website development does not: multi-tenancy, subscription billing, role-based access control, usage metering, and the infrastructure to scale as your customer base grows.
CV Infotech has been building SaaS products since the early years of the company. Our most visible long-term SaaS work includes UltimaBot, an enterprise AI automation platform active since 2019, and UltimaWriter, an AI content generation platform — both built and maintained by the same CV Infotech team across the full lifecycle.
We will tell you honestly if an existing SaaS tool solves your problem. Custom SaaS development is the right choice when your business model does not fit existing tools, when you are building a platform to generate subscription revenue, when compliance requirements prevent third-party SaaS, or when you need to white-label a product for your own customers. If an existing tool covers 90% of your needs, we will say so.
Multi-tenant architecture
Single codebase, isolated data per tenant. PostgreSQL row-level security enforces isolation at the database level — not just the application layer.
MVP-first approach
Validate your product with real users before scaling. We build MVPs on production-ready architecture so there is no rewrite when you grow.
Security by design
Authentication, data isolation, and compliance requirements are architecture decisions, not afterthoughts. Built in from the first sprint.
Billing and subscriptions
Stripe integration for per-seat, usage-based, tiered, and freemium models. Trial periods, upgrade flows, proration, and invoice management.
SaaS development services
From initial MVP through to multi-region enterprise deployment, CV Infotech covers the full SaaS development lifecycle.
SaaS MVP development
A production-ready MVP with core features, authentication, multi-tenancy, and billing integration. Built on architecture that scales — not a throwaway prototype. Typical timeline: 3-5 months.
Learn moreMulti-tenant platform architecture
Full-stack SaaS architecture with row-level security, tenant isolation, shared infrastructure, and per-tenant configuration. PostgreSQL, Node.js, and Next.js are our standard SaaS stack.
Learn moreSaaS API development
API-first design with documented REST endpoints, webhook support, rate limiting, and API key management. Built for third-party integrations and mobile app consumption from day one.
Learn moreSaaS migration and modernisation
Migrate from a monolith, a WordPress-based SaaS, or a legacy platform to a modern multi-tenant architecture without losing data or disrupting existing customers.
Learn moreWhite-label SaaS development
Build a SaaS product that your customers resell under their own brand. Custom domain support, theme configuration per tenant, and fully white-labelled email and notifications.
Learn moreSaaS maintenance and scaling
Ongoing engineering support after launch — performance optimisation, database scaling, new feature delivery, security reviews, and infrastructure management as your user base grows.
Learn moreSaaS development that still works five years later
We have been maintaining SaaS products we built years ago. That is only possible when the original architecture was correct. The decisions made in week one of a SaaS build determine the maintenance cost, the security posture, and the scaling ceiling for the life of the product.
🇺🇸 USA
CCPA-compliant data handling. AWS us-east-1 for primary US deployments. EST timezone overlap for daily standups. Stripe USD billing. SOC 2 readiness incorporated when specified.
🇬🇧 United Kingdom
UK GDPR architecture by default for UK clients. AWS eu-west-2 (London) region. GMT-aligned communication. UK company registration and VAT invoice support via Stripe.
🇦🇺 Australia
Privacy Act 1988 compliance built in. AWS ap-southeast-2 (Sydney) for AU deployments. AEST timezone flexibility. Laura Maher, our AU client: 'Communication is 10 out of 10.'
Security first, always
Multi-tenant data isolation is implemented at the PostgreSQL row-level security layer — not just in application code. A misconfigured API route cannot expose cross-tenant data.
Architecture that scales
We have maintained SaaS products built in 2019 without rewriting the core architecture. The right decisions early save months of migration work later.
Same engineers, long-term
The team that builds your SaaS maintains it. No handover documentation, no knowledge loss, no 'who built this?' moments when something needs to change.
Fixed scope, honest pricing
Discovery produces a fixed-scope document. The price does not change unless the scope changes. No retainers before you have seen the first milestone.
SaaS development process
From first conversation to a running production SaaS product — six phases, each with a clear deliverable before the next begins.
Discovery and scoping
Weeks 1–3We document every user journey, every data entity, the billing model, the role hierarchy, and the integration requirements before any code is written. The output is a fixed-scope document with timeline and price. Nothing starts without sign-off.
Architecture and security design
Weeks 3–5Multi-tenant database schema, authentication system, API contract, billing integration plan, and infrastructure topology are all designed and reviewed before the first line of application code. Security is designed in — not retrofitted.
Core platform build
Months 2–5Authentication, multi-tenancy, billing integration, role-based access control, and the core application features are built and tested. The staging environment mirrors production. Each feature is tested before the next sprint begins.
Beta and user testing
Month 5–6Real users test the platform in a staging environment. Issues are prioritised and resolved before launch. Performance is profiled under realistic load. Security is reviewed end-to-end. The client's team is trained on the admin panel.
Production launch
Month 6–7DNS migration, SSL, production database seeding, payment method activation, and first real customer onboarding. We stay close for the first 30 days — monitoring dashboards, responding to edge cases, and resolving any issues that appear at real-world scale.
Growth and ongoing development
OngoingPost-launch, development continues in sprint cycles — new features, performance improvements, infrastructure scaling, and security updates. The same engineers who built the platform continue to own it. No knowledge transfer, no handover risk.
SaaS development questions
Let's scope it properly first.
Whether you have a detailed spec or a back-of-napkin idea, the next step is the same: a structured discovery conversation to define scope, timeline, and price. No obligation, no guesswork.
