SaaS product development

A SaaS Development Company for Founders Who Need to Ship, Learn and Scale

Our SaaS development services are aimed at founders and small product teams who need a real, billable product in front of customers quickly, built on foundations that will not need rewriting once it gains traction. We handle the product engineering: accounts and teams, tenant isolation, subscriptions, admin tooling and the core feature that makes your product worth paying for.

We are deliberately opinionated about the MVP. The first version should prove that people will sign up and pay, so we help you cut scope to the workflow that matters, ship it in weeks, and put analytics in place to see how customers actually use it. Everything else goes on a roadmap informed by evidence.

When the product starts growing, you do not need to switch to a bigger SaaS development agency. The same team keeps going: performance work, more integrations, usage-based pricing, SSO for larger customers and the reliability improvements that come with paying users. Because you own the code from day one, you can also hire in-house engineers later and hand over cleanly.

Who it's for

Who SaaS Development is for

Non-technical founders

Founders with a validated problem and early customer conversations who need a dependable engineering partner to turn the idea into a working, paid product without hiring a full team first.

Technical founders short on hands

CTOs or solo engineers who have designed the product and want experienced developers to build alongside them, following their architecture, code standards and review process.

Businesses productising an internal tool

Companies that built something useful for themselves and now want to sell it to others, which means adding multi-tenancy, onboarding, billing and proper support tooling.

Existing SaaS needing a rebuild or extra capacity

Products held back by an ageing codebase, a single-tenant design or slow releases, where the team needs help modernising the stack or shipping a backlog of features.

What you get

Features we build

Multi-tenant architecture

Each customer organisation gets its own isolated workspace. We choose between shared-schema with tenant IDs, schema-per-tenant or database-per-tenant based on your compliance needs and expected scale, and enforce isolation in the data layer, not just the UI.

Subscriptions and billing

Plans, trials, seat-based or usage-based pricing, coupons, proration and invoices through Stripe Billing for international customers or Razorpay Subscriptions for India. Webhooks keep account access in step with payment status, including failed-payment retries.

Authentication, teams and roles

Email and social sign-in, magic links, two-factor authentication, team invitations and role-based permissions. SAML or OIDC single sign-on can be added when you start selling to larger companies that require it.

Admin and support console

An internal panel to find any customer, see their plan and usage, extend a trial, issue a credit, impersonate a user for troubleshooting with an audit log, and manage feature flags without a code deploy.

Product analytics and metrics

Event tracking with tools like PostHog or Mixpanel for activation and retention, plus a revenue view of MRR, churn and plan mix, so you can make roadmap decisions from data rather than guesswork.

Public API and integrations

A documented REST or GraphQL API with API keys and rate limits, outbound webhooks, and connectors to tools your customers already use, such as Slack, Google Workspace, HubSpot or Zapier.

Onboarding and in-app messaging

Sign-up flows, guided setup checklists, sample data, transactional emails and in-app announcements designed to get new users to their first useful result quickly, which is usually where SaaS trials are won or lost.

Built for growth and reliability

Automated tests, CI/CD pipelines, background job queues, error monitoring, database backups and infrastructure as code, so shipping weekly stays safe as the customer base and codebase grow.

How we work

From first call to launch

  1. 01

    Product discovery

    We work through your target customer, the core job the product does, pricing model and competitors, then agree on the smallest feature set that can win a paying first customer.

  2. 02

    UX and architecture

    We design clickable screens for the main flows and decide on the tenancy model, data structure, hosting and third-party services, documenting the reasoning so future engineers understand the choices.

  3. 03

    MVP build

    We build in weekly or fortnightly increments with a live staging environment, so you can demo progress to early users and investors while development continues.

  4. 04

    Launch and instrument

    We set up production hosting, billing in live mode, analytics, error tracking and status monitoring, then support you through the launch to your first cohort of customers.

  5. 05

    Iterate and scale

    Based on usage data and customer feedback, we continue on a monthly retainer or project basis, adding features, improving performance and hardening security as you grow.

Why RED SAG

Why teams choose us

Scope discipline for MVPs

We push back on features that do not help you win the first paying customers. That keeps your runway intact and gets a real product into users' hands sooner.

Your IP, from the first commit

Code lives in your repository and infrastructure in your cloud account throughout the project. That matters to investors in due diligence and makes it easy to bring engineering in-house.

Useful time-zone overlap

Our India-based team plans overlap hours with clients in the UK and Europe, and schedules morning or evening calls for the US, Canada and Australia, so questions get answered within a working day.

Direct line to the engineers

You work with the developers writing your product, not a sales layer. Decisions are faster, trade-offs are explained plainly, and nothing gets lost in translation.

FAQ

Frequently asked questions

How much does SaaS development cost for an MVP?

A lean SaaS MVP with one core workflow, teams, billing and an admin panel usually costs ₹1.75–3.5 lakh (roughly $2,700–5,400) with us. A more complete launch-ready product is typically ₹3.5–9 lakh. The biggest cost drivers are the number of user roles, integrations and how complex the core feature is. We quote a fixed price after a short discovery phase.

How long does it take to build a SaaS MVP?

SaaS MVP development with us usually takes 8–12 weeks from discovery to launch. The first two weeks cover discovery, design and architecture; the remaining weeks are building and testing in increments you can see on a staging site. Delays usually come from changing scope mid-build or slow feedback, so we agree on a decision-maker and a weekly review slot at the start.

Do you build multi-tenant SaaS?

Yes, every SaaS product we build is multi-tenant from the start, because retrofitting it later is expensive. For most early products a shared database with strict tenant scoping is the right balance of cost and safety. If you expect enterprise customers with data-residency or isolation requirements, we plan for separate schemas or databases per tenant.

Should I use Stripe or Razorpay for subscriptions?

If most customers are outside India, Stripe Billing is usually the better fit for international cards, tax tools and invoicing. For Indian customers paying in rupees, Razorpay Subscriptions handles domestic cards, UPI mandates and RBI e-mandate rules more smoothly. Many products use both, routing customers by country. Card data stays with the gateway, which keeps your PCI DSS scope small.

Will I own the code and intellectual property?

Yes. Our agreement assigns all IP in the work we produce to you, and the code sits in your Git repository from the first day. Hosting, domains and third-party accounts are registered to your company. That keeps you in control and makes investor due diligence straightforward.

Can you work with our in-house developers or CTO?

Yes. Many clients have a technical founder who sets architecture and reviews pull requests while we provide extra engineering capacity. We follow your branching, testing and code review conventions, join your standups, and write documentation so your team can take over any part of the system without depending on us.

We are based in the US, UK or Australia. How does working with you look?

As a SaaS development company in India working with overseas founders, we schedule a regular call at a time that suits both sides, usually your morning for the UK and Europe and your evening or early morning for the US, Canada and Australia. Day-to-day updates happen in Slack or similar, with a shared board showing progress. Contracts, invoicing in USD, GBP or EUR, and NDAs are all routine for us.

How do I choose between SaaS development companies?

Lists of the top SaaS development companies tell you little about who will actually build your product. Ask to speak with the engineers, not just sales, and ask how they handle tenant isolation, billing webhooks and failed payments. Check that the code and cloud accounts will be in your name from day one, and ask for a fixed quote tied to a written scope. The best SaaS development company for you is the one that pushes back on scope and explains trade-offs plainly.

How do you handle data privacy for SaaS customers?

We design with GDPR and UK GDPR, CCPA and India's DPDP Act 2023 in mind: encryption in transit and at rest, access logging, data export and deletion tools, and hosting in the region your customers expect. Legal compliance ultimately depends on your policies too, so we help you implement the technical side your privacy counsel specifies.
