SaaS Development Services

SaaS development services covering the parts a normal web build does not have: multi-tenant architecture that keeps each customer’s data isolated, subscriptions and billing wired to a payment provider and reconciled properly, accounts and permissions, and infrastructure that holds up when usage climbs. You can hand us the whole product, or hire SaaS developers to work on one you already have.

Scope your SaaS

We run our own SaaS

Managable is a live multi-tenant product we built and operate.

Foundations first

Tenancy, billing and auth done properly — they are expensive to retrofit.

You own it

The code, the infrastructure and the accounts are yours.

The foundations are what break, and they break late

Tenancy was bolted on afterwards, and now one customer can see a sliver of another customer’s data.

Billing does not reconcile: someone upgraded mid-cycle, and nobody can explain what they were charged.

Auth, roles and team permissions were added feature by feature, and no one is confident who can do what.

It works fine at fifty accounts and falls over at five hundred, because nothing was ever load-tested.

The developer who understood the infrastructure has left, and the deploy process lives in their head.

These are the parts that are cheap to get right at the start and brutal to retrofit later. We build them first — tenancy, billing, auth, infrastructure — then the product on top, so the thing you sell is not sitting on a foundation you are afraid to touch.

What you get

Multi-tenancy

One platform, many customers, and no path between them. Isolation is enforced at the database layer with row-level security rather than trusted to application code, because application code is where the mistakes happen. The tenancy model is chosen deliberately — shared schema, separate schema, or separate database — against your compliance and scale requirements, not by default.

Subscriptions & billing

Plans, trials, upgrades, downgrades and cancellations wired to a billing provider such as Stripe, with webhooks handled idempotently so a retried event never double-charges. Mid-cycle changes are prorated correctly and reconciled against your own records, so you can always answer what a customer was charged and why.

Accounts & teams

Sign-up, sessions, roles, invitations, team management and permissions designed as one system at the start, rather than accreted feature by feature until nobody is sure who can do what. Sensitive actions are attributable to a person and reviewable after the fact.

Scalable infrastructure

Built so that growth is a configuration problem, not a rewrite: sensible indexing and query patterns before the tables are large, background jobs off the request path, and the observability to know which part is slow before a customer tells you.

MVP focus

A first version scoped to prove the product, not to include everything at once. What gets cut is the part that can be added later; what stays is the part that would be expensive to add later. That is the whole discipline.

Integrations & API

The third-party connections your customers expect, and a public API designed for people you will never meet — versioned from the first endpoint, authenticated properly, rate-limited, and documented rather than reverse-engineered.

How we work

Scope the MVP

We define the smallest version that is genuinely sellable and agree what it includes.

Build

Iterative development with a working product you can demo throughout.

Launch

Deploy with billing, accounts and monitoring in place.

Scale

Add features and capacity as real usage tells you what matters.

Hire SaaS developers

You do not always need a product built from nothing. Often there is already a SaaS — it works, it has customers — and what is missing is senior people who have done this before: someone to fix the tenancy model before it leaks, wire the billing so it reconciles, or take the infrastructure off the shoulders of the one developer who understands it.

You can hire SaaS developers from us for exactly that. We work as a small senior team inside your product, on your repository, to your review process. No account manager sits between you and the person writing the code.

It suits three situations in particular: an existing product that has outgrown the people who built it; a founding team that can build features but has never run multi-tenant billing or infrastructure in anger; and a company that needs a specific thing done properly — an API, a migration, an auth rebuild — without hiring permanently for it.

SaaS product development

Building the software is the easier half. The harder half is deciding what to build, in which order, and what to leave out — and that is what separates a SaaS product from a pile of features with a login screen.

SaaS product development means treating the roadmap as the deliverable: discovery to establish what customers will actually pay for, a first release scoped to prove it, then iteration driven by what real usage tells you rather than what the loudest customer asked for last week. Features that would be expensive to add later go in early; features that can wait, wait.

What is included in our SaaS development services

Multi-tenant architecture with isolation enforced at the database layer. Subscriptions and billing wired to a provider such as Stripe, with webhooks handled idempotently and mid-cycle changes prorated and reconciled. Sign-up, sessions, roles, invitations and permissions designed as one coherent system.

Infrastructure with sensible indexing before the tables are large, background jobs off the request path, and observability so you know what is slow before a customer does. A versioned, authenticated, rate-limited public API. And the source code, the infrastructure and the accounts — all of it yours.

We build and run our own SaaS

Managable is a multi-tenant CRM for freelancers that we designed, built and operate — the same tenancy, billing, auth and infrastructure decisions described above, made on our own product and lived with afterwards.

That matters more than it sounds. An agency that ships and leaves never finds out which of its architectural shortcuts were expensive. We are still running ours.

Common questions

Can you build just an MVP first?

Yes, and we recommend it. A focused MVP gets you to real users and revenue before you over-invest.

How are payments handled?

Through an established billing provider such as Stripe. Webhooks are handled idempotently, so a retried event never double-charges, and mid-cycle upgrades and downgrades are prorated and reconciled against your own records — which means you can always answer what a customer was charged and why.

Will it scale?

We build the foundations — multi-tenancy and infrastructure — so growth does not force a rewrite.

Can I hire SaaS developers for a product I already have?

Yes, and it is one of the most common reasons people come to us. We work inside your existing product, on your repository and to your review process, as a small senior team. Typical work is fixing a tenancy model before it leaks, making billing reconcile, rebuilding auth and permissions coherently, or taking infrastructure off the shoulders of the one developer who understands it.

How do you develop a SaaS application?

Foundations first, because they are cheap now and brutal to retrofit: the tenancy model, billing, authentication and permissions, and infrastructure. Then the smallest genuinely sellable version of the product on top of them. Then iteration driven by real usage. The order matters more than the technology — most failing SaaS products were built in the reverse sequence.

What is SaaS product development?

It is the discipline of deciding what to build, in which order, and what to leave out. Discovery establishes what customers will actually pay for; a first release is scoped to prove it; iteration is driven by what usage shows rather than by whoever complained most recently. Features that would be expensive to add later go in early. Everything else waits.

Do you work as a white-label SaaS development partner?

Yes. Some of our work is delivered under another agency’s or consultancy’s name, where they own the client relationship and we provide the senior engineering. The arrangement is straightforward, and we are equally happy being invisible.

Can a solo developer build a SaaS?

For a first version, genuinely yes — plenty of good products started that way, and it is often the right call. Where it usually comes unstuck is the unglamorous half: multi-tenant isolation, billing that reconciles under edge cases, and infrastructure that survives the first real traffic. Those are the parts worth bringing experienced people in for, and the parts most expensive to fix once customers depend on them.
