SaaS product development
Tankar builds and runs its own SaaS products, and it builds SaaS for clients the same way, with a roadmap, multi-tenant architecture, subscription billing, observability and a release process. An MVP typically launches in 8 to 12 weeks, then the product grows in planned releases.

Built like a product, not a project
A SaaS product is not finished at launch. Tankar plans for what comes after from the first sprint: tenancy that scales, billing that handles trials and upgrades, monitoring that shows what customers actually do, and a release process that lets the product change every week without downtime.
What an MVP includes
One core workflow done well, self-serve onboarding, plans and billing, an admin console, analytics events and the operational basics: backups, monitoring, error tracking and a status page. Everything else goes on the roadmap with an honest note about why it waits.
After launch
The roadmap becomes planned releases. A dedicated team or a product partnership keeps the same pod on the product, and a monthly report covers usage, errors, cost and what is recommended next.
Typical engagements

- Multi-tenant SaaS with role-based access and subscription billing on Stripe or Razorpay
- MVP for a funded startup, launched in 8 to 12 weeks with an admin console and analytics

- Public API and webhooks so customers can integrate the product
- Rewrite of a single-tenant application into a multi-tenant platform
How it runs
The stages this service goes through, and what you see at each one.
Discovery
Who pays, who uses it every day, and what they do today without the product. Scope document and a written estimate within 48 hours.
The written estimate follows within 48 hours of the scoped call.
Design
Onboarding, the core workflow and billing screens prototyped first, because those decide whether a trial converts.
Build
Sprints with a weekly demo. Tenancy, authentication, billing and observability go in during the first sprints, not at the end.
An MVP typically runs 8 to 12 weeks from discovery to launch.
Test
Automated tests on every pull request, tenant-isolation checks, load tests on the paths customers hit most, and a security review.
Launch
Production environment, monitoring, status page, backups and a release checklist.
Run
Planned releases from the roadmap, an SLA-backed support plan and a monthly report on usage, errors and cost.
- Timeline
- An MVP typically takes 8 to 12 weeks from discovery to launch. After launch the product grows in planned releases.
- Team shape
- A product pod with a named project manager, a designer, engineers and a QA engineer. For product partnerships a director joins the roadmap review.
Stack for this service
The technologies this work is usually built on, and why each one is used here.
| Technology | Why we use it here |
|---|---|
| Next.js | Public pages are server-rendered for search and speed, and the application shell stays fast on a large product. |
| TypeScript | Shared types between the API and the interface reduce the bugs that show up as billing or permission errors. |
| Node.js | A common API layer for the web app, the mobile app and customer integrations. |
| PostgreSQL | Row-level tenancy, transactions for billing, and reporting in one database. |
| Redis | Sessions, rate limits, queues and caching for the paths every tenant hits. |
| GitHub Actions | Tests and deployments on every pull request, so releases are routine rather than events. |
