What SaaS development actually involves
SaaS development means building software that many customers use through a browser, on a subscription, without installing anything. The feature you pictured is the visible part. Underneath it sits sign-up, plans and billing, organisations and roles, invitations, an admin panel for your support team, transactional emails, usage reporting and a way to deploy changes without taking the product down.
On most projects, roughly half the work is that supporting software. It is also the half that quotes tend to leave out, which is why so many SaaS builds run over.
The parts of a web product people underestimate
The specifics that decide whether a platform survives its first hundred customers:
- Tenancy. One customer must never see another's data, and proving that to an enterprise buyer means audit logs, not assurances.
- Roles and permissions. Owner, admin, member, billing contact, read-only. Every screen needs an answer for each.
- Billing edge cases. Failed cards, mid-cycle upgrades, refunds, annual plans, taxes in more than one country.
- Invitations and onboarding. The path from "someone signed up" to "their whole team is using it", which is where most trials quietly die.
- The admin panel. Your support team needs to look up a customer, extend a trial and fix a mistake without asking an engineer.
We build these in the first half of the project, not the last week, because they are the parts that are painful to add later.
Multi-tenancy and pricing models
How you charge shapes what we build, so we settle it during discovery.
| Pricing model | What it means for the build |
|---|---|
| Per user, per month | Seat management, invitations, proration when the team changes size |
| Tiered plans | Feature flags per plan, upgrade prompts, limits enforced in the API |
| Usage based | Metering you can trust, usage dashboards, alerts before a bill surprises someone |
| Flat fee per company | The simplest to build, and often the right way to start |
Our web and SaaS development process
- Discovery, week 1. Users, roles, the core workflow, the pricing model and the integrations. You get a fixed scope and a fixed price.
- Design, weeks 2 to 4. Flows, then screens, then a clickable prototype. Web products live or die on the boring screens, so we design the settings and admin pages too, not only the marketing-friendly ones.
- Build, weeks 5 to 16. Weekly demos on a staging environment you can log into. Tenancy, auth and billing go in early; the feature you are excited about comes with them.
- Launch. Staged rollout, monitoring, backups tested by restoring them, and a month of fixes included.
The timing logic is the same one in how long an MVP takes, and the budget logic is in our app development cost guide.
The technology we use
Next.js and React with TypeScript, because server rendering gives us pages that rank and an app that feels quick on Indian mobile networks. Node, Python or Laravel for the backend, PostgreSQL for most data, Redis where speed demands it, and AWS, Google Cloud or Vercel for hosting. The full list is on the technologies page.
Performance and search, built in rather than bolted on
Most agencies hand you a site and then sell you an SEO retainer to fix what they built. We do it the other way round: metadata, structured data, sitemaps and Core Web Vitals are part of the build, and the build fails if a page is missing a title or description.
This website is the proof. It scores 95 and above for performance and 100 for SEO on Lighthouse, every page ships structured data, and the sitemap is generated from the content so it cannot go stale. That work is also available on its own, as SEO and AI search optimisation.
Adding AI to a web product
The three additions that usually pay for themselves are search that understands meaning, an assistant over your own documentation, and automatic summaries where your users currently read long records. We build them behind a feature flag with a control group, so you can see whether the number moved before rolling them out.
If you already have a platform, that is AI integration. If the AI is the product itself, see LLM and generative AI apps.
Taking over a platform someone else built
We audit before we quote: the code, the database, the hosting bill, the security basics and the backlog. Two weeks later you get a written recommendation with the cost of fixing, replacing in part, or rebuilding.
What it costs and how long it takes
Web and SaaS projects with us usually run 10 to 20 weeks, at a price fixed after discovery. The largest cost drivers are the number of user types, the pricing model, and how many outside systems the platform has to talk to. If your product needs a mobile app as well, see mobile app development; building both together is cheaper than building them a year apart.
