SaaS engineering / Madurai, India
SaaS Software Development Services
We build multi-tenant SaaS platforms on Laravel and NestJS + Next.js — API-first, billing-ready, and designed to hold up when your tenant count goes from ten to ten thousand. Every engineer on our team works with Claude Code, so the groundwork that used to eat your first three months now takes weeks.
Where we come in
Two ways companies start a SaaS build with us
Most conversations we have fall into one of these. Both end in the same place: a tenant-aware platform you can sell subscriptions against.
You're launching a new SaaS product
You have a market, a wedge, and pressure to get a paying customer before the runway argument starts. We scope the smallest version that a customer will pay for, then build it properly enough that version two isn't a rewrite.
- Product and technical discovery, then a costed release plan
- Tenant model, data isolation and permission design agreed before code
- Working MVP with billing and onboarding, typically in 10–16 weeks
- Instrumentation from day one, so you learn from real usage
You're turning existing software into SaaS
You already have a product that gets installed per client, or an internal tool your customers keep asking to buy. The hard part isn't the features — it's tenancy, billing and access control retrofitted without breaking the customers you have.
- Audit of the current codebase, data model and deployment story
- Staged migration to multi-tenant, with existing clients kept live
- Self-serve signup, plans, metering and invoicing added on top
- Cloud infrastructure sized so one noisy tenant can't take down the rest
Architecture
API-first, with services split only where the load is
Every capability is built as an API before any screen consumes it. Your web app, your mobile app, and the customer integrating with you all use the same documented contract — which is what makes a partner integration a week of work instead of a quarter.
We don't split a product into twelve microservices on day one. We start with clean module boundaries, then break out the pieces that genuinely need to scale or fail independently: reporting, notifications, file processing, integrations, billing webhooks. That keeps your infrastructure bill sane while the product is still finding its shape.
Contracts are documented in OpenAPI, versioned, and covered by contract tests, so a change in one service doesn't quietly break another.
Tenant web app, admin console and companion mobile apps — all talking to the same API.
Authentication, tenant resolution, rate limiting and request logging in one place.
Domain modules with their own boundaries — extracted into separate services when load or release cadence demands it.
Exports, imports, emails, billing webhooks and scheduled jobs kept off the request path.
Tenant isolation enforced at the query layer, with backups and restore drills that are actually tested.
Core capabilities
The parts of a SaaS product that are hard to retrofit
Features are negotiable. These six are the ones that decide whether your platform can still be sold and supported three years from now, so we build them in from the start.
Tenant isolation you can explain to a buyer
Shared schema, separate database per tenant, or a hybrid for your enterprise accounts. We pick based on your compliance and data-residency requirements, then enforce it at the query layer so it can't be bypassed by a new feature.
Built to hold under real load
Horizontal scaling, queue workers, read replicas, caching and CDN delivery, with load testing before launch rather than after the first outage. Autoscaling rules are tuned so cost tracks usage instead of running ahead of it.
Billing that matches how you sell
Plans, tiers, trials, seat counts, usage metering, coupons, proration, dunning and invoices — wired to Stripe, Razorpay, Paddle or a local gateway. Plan limits are enforced in the product, not just on the pricing page.
Role-based access down to the field
Owner, admin, manager, member and custom roles per tenant, with granular permissions on records, actions and fields. Add SSO, invite flows, audit logs and IP restrictions when your first enterprise deal asks for them.
Companion apps on the same API
Flutter apps for iOS and Android that share your platform's API contract — offline capability, push notifications, biometric login and store release management handled by our three dedicated mobile engineers.
Releases that don't need a war room
CI/CD pipelines, staging that mirrors production, zero-downtime deploys, error tracking, uptime monitoring and structured logs. Support gets the tooling to answer a customer question without pulling an engineer off a sprint.
Technology
Laravel or NestJS + Next.js — and how we choose
We run two SaaS stacks properly rather than six badly. Both are backed by internal libraries we've built over eight years, which is a large part of why our first release lands quickly.
| Decision point | Laravel | NestJS + Next.js |
|---|---|---|
| Best fit | Business platforms with deep admin, heavy reporting, invoicing and document workflows | Real-time products, event-driven systems and platforms where one TypeScript language across the stack matters |
| Speed to first release | Fastest — auth, queues, billing and admin scaffolding are mature and we reuse our own modules | Fast, with more up-front architecture; pays back as the service count grows |
| Frontend | Blade with Livewire, or a decoupled React or Next.js client | Next.js with server rendering — better for public SEO surfaces and marketing-led signup |
| Data layer | MySQL or PostgreSQL with Eloquent | PostgreSQL, MongoDB or both, with Prisma or TypeORM |
| Microservices | Modular monolith first, services extracted where load justifies it | First-class support for service boundaries, message queues and gRPC from the start |
| Team you get | Laravel engineers who have shipped six production SaaS products of our own | Node and React engineers working across client platforms in the USA, Australia, Europe and Dubai |
Around both stacks: Flutter and Kotlin for mobile, AWS or DigitalOcean for infrastructure, Docker for parity between environments, and integrations with open-source tools like Mautic and Dolibarr when marketing automation or ERP needs to sit alongside your product.
AI-assisted delivery
Why our SaaS timelines look different now
All 18 engineers at GegoSoft work with Claude Code as standard daily tooling. This isn't a pilot or a line on a capability deck — it's how the team writes, reviews and refactors every day, and it changes SaaS economics in specific ways.
What gets faster
- Scaffolding tenancy, RBAC, billing and API layers — the repetitive 30% of a SaaS build
- Test coverage written alongside features rather than deferred to a later sprint
- Migrating and refactoring legacy code into a tenant-aware structure
- API documentation, SDKs and integration guides staying current with the code
What stays human
- Tenant model, data isolation strategy and permission design
- Pricing, packaging and plan-limit decisions that affect revenue
- Security review, dependency auditing and production readiness sign-off
- Code review — nothing reaches your main branch without an engineer approving it
Proof
We run our own SaaS products, so we've paid for these mistakes already
Six products in production, plus long-term platform work for clients across four regions. The tenancy, billing and permission patterns we bring to your build came from operating software, not from a template.
GegoK12
Open-source school ERP running for 20+ international clients — multi-school tenancy, role-based access across staff, parents and students, and companion mobile apps.
BOQ Manager
Bill-of-quantities platform with project-level permissions, structured approval flows and export-heavy reporting for estimation teams.
ChemTracker
Chemical inventory and compliance tracking, built for organisations that need audit trails and strict data separation between sites.
eTender
Tender management with time-bound access rules, sealed submissions and role separation between buyers, evaluators and vendors.
Microfinance banking platform
Long-term engagement on a lending and collections platform — branch-level access control, scheduled jobs and a field-facing mobile app on the same API.
Field force management system
Workforce tracking and job dispatch with offline-tolerant mobile clients, live location handling and per-organisation configuration.
Engagement
How a SaaS build runs with us
Fixed-scope phases where the requirements are clear, a dedicated team where they aren't yet. Either way you get a named tech lead and a demo every two weeks.
Discovery workshop
Two weeks. We map users, tenant model, permission matrix, integrations and pricing mechanics, then hand you a costed release plan — yours to keep whether or not you build with us.
Architecture and API contract
Data model, service boundaries and the OpenAPI spec agreed before feature work starts, so web and mobile can be built in parallel.
Build in two-week sprints
Working software demoed every sprint on a staging environment you can log into. Priorities can change between sprints without renegotiating the contract.
Billing, onboarding and hardening
Subscription flows, plan limits, trial and dunning logic, load testing, security review and a production readiness checklist signed off item by item.
Launch
Infrastructure provisioned, monitoring and alerting live, runbooks written, and your team trained on deploys and support tooling.
Iterate and support
Ongoing sprints against real usage data, plus an SLA-backed support arrangement if you'd rather not build an in-house platform team yet.
Questions we get asked
SaaS development, answered plainly
How long does it take to build a SaaS MVP?
Most first releases land in 10 to 16 weeks, covering the core workflow, multi-tenancy, subscription billing, role-based access and one companion mobile app if you need it. The range depends on integration count and how settled your requirements are. Products built on our existing frameworks and internal libraries sit at the shorter end.
Should we build our SaaS on Laravel or NestJS?
Laravel gets you to a paying customer fastest for business platforms with heavy admin, reporting and billing — its ecosystem covers most of that out of the box. NestJS with Next.js suits real-time or event-driven products and teams who want TypeScript across the whole stack. We make the call during discovery based on your product, your hiring plans and where the load will actually be.
Do we need microservices from day one?
Almost never. A well-structured modular monolith with clear boundaries is cheaper to run, faster to ship and easier to hire for. We design so services can be extracted later, then extract the ones that genuinely need independent scaling or release cycles — usually reporting, notifications, file processing or billing webhooks.
Can you convert our existing software into a SaaS product?
Yes — that's a large part of our work. We audit the current codebase and data model, design the tenant strategy, then migrate in stages so existing clients stay live throughout. Subscription billing, self-serve onboarding and role-based access are layered on once the tenancy foundation is stable.
Which payment gateways do you integrate for subscriptions?
Stripe, Razorpay, Paddle, PayPal and regional gateways as needed. We handle plans, trials, seat-based and usage-based pricing, proration, coupons, dunning, tax handling and invoice generation, with webhook processing built to survive retries and out-of-order delivery.
Do you build the mobile apps too?
Yes. Three dedicated mobile engineers build Flutter, Kotlin and Android companion apps against the same API as your web product, including offline support, push notifications and App Store and Play Store release management.
Who owns the code?
You do. Full IP transfer, source in your repositories from the first commit, and infrastructure in your cloud accounts. There's no dependency on us to keep operating the product.
What does AI-assisted development mean for cost and quality?
Our engineers use Claude Code daily, which speeds up scaffolding, testing, refactoring and documentation — the repetitive share of a SaaS build. That shortens timelines and lets more of your budget go toward product decisions. Architecture, security review and code review stay with senior engineers; nothing reaches your main branch unreviewed.
