How much does it cost to build a SaaS platform?

It depends on what the first version has to do, so we price it after a short discovery and fix that price in writing before work starts. Cutting the first version to an MVP is the usual way to bring it within budget.

What is an MVP, and do I need one?

A minimum viable product is the smallest version a customer would pay for. For a new product it is usually the right start, because real customers then decide what is worth building next.

Who owns the code and the customer data?

You do. The code is handed over in your own repository, the accounts are in your name, and the customer data is yours.

Can you take over an existing SaaS product?

Yes. We read the code first and tell you honestly what is worth keeping, then quote the changes or the rebuild.

Is the platform GDPR compliant?

We build with GDPR in mind: separated customer data, access control, data export and deletion. Your privacy policy and data processing terms are still your legal responsibility, and we recommend a lawyer reviews them.

Can a SaaS platform have a mobile app too?

Yes. Because everything runs through an API, a mobile app can be added later without rebuilding the platform.

RIGTech

SaaS Development

SaaS development for founders and companies: subscriptions, accounts, admin and cloud, from MVP to launch, at a fixed price with the source code handed over.

In short

RIGTech designs and builds SaaS platforms: web applications customers sign up for and pay for by subscription. We take a product from the first idea through an MVP to launch, including accounts, billing, an admin panel and the cloud setup. The price is fixed in writing before development starts, the people on your first call write the code, and the source code is yours.

Who this suits

Founders launching a software product, and established businesses turning something they know well into a subscription product. It also suits teams whose first version, often no-code or written in a hurry, has reached its limits.

If you are still deciding what the first version should contain, start with product strategy and MVP planning.

What a SaaS platform needs to work

The feature that makes your product different is usually the smaller part of the build. Around it sits everything a subscription business needs on day one:

Sign-up, login and password recovery, with roles and permissions for teams.
Multi-tenancy, so each customer sees only their own data.
Subscription billing: plans, trials, card payments, invoices, upgrades and cancellations.
An admin area where you can see your customers and help them.
Email notifications, audit logs and data export.
Hosting, backups and monitoring sized for the customers you have, ready to grow.

The technology we use

Usually React and TypeScript in the browser, Node.js on the server and PostgreSQL for the data, with Stripe or a similar provider for subscription billing. These are mainstream choices on purpose: whoever maintains the platform after us, including your own future team, can hire for them easily. If your product has a good reason to need something else, we will say so during planning.

What affects the price of a SaaS platform

How many user roles and how much of the product exists in the first version.
Integrations with other tools, such as invoicing, CRM, email or accounting.
How complicated your billing is: flat plans cost less than usage-based pricing.
Compliance needs specific to your industry, on top of GDPR.

A SaaS platform is priced after a short discovery, then fixed in writing before we build. If the full idea is more than the budget, we cut it to an MVP that can win its first paying customers.

How a SaaS project runs

Discovery: We talk through the idea, the customers and how they will pay. You get a written scope, a timeline and a fixed price for the first version.
Product design: Screens and flows for the main journey, from sign-up to the moment a customer gets value. You see and change them before any of it is built.
MVP development: Accounts, billing and your core feature, with a working build to try every week. Changing direction stays cheap because you see it early.
Launch: Production hosting, payments switched to live, monitoring and backups in place, then your first customers on the platform.
Growth: Real usage decides what gets built next. You keep talking to the engineers who built it, and you own the code either way.

How a SaaS platform is put together

A typical architecture. Each customer has separate data; billing and email are handled by specialised providers rather than rebuilt.

Your users: Customer web app, Team accounts and roles, Your admin panel
Application: API, Authentication, Your core features, Background jobs
Services: Subscription billing, Transactional email, File storage, Integrations
Foundation: Multi-tenant database, Backups, Monitoring, Automated deployment
