Build

Multi-tenant SaaS product development

We build multi-tenant products from the first release to the version that carries real load: tenancy, billing, onboarding, permissions and the deployment path. Then we stay on and run it.

What this covers

Multi-tenant SaaS product development, end to end.

First release scope

We cut the idea down to the release that can go live and earn feedback. What ships first, what waits, and which decisions are expensive to reverse later. You end up with a scope that can be priced.

Multi-tenant architecture

Tenancy is the decision you cannot easily undo. We set out how customer data is separated, how a tenant is provisioned, and what happens when one customer grows far larger than the rest.

Billing, plans and entitlements

Plans, seats, trials, upgrades, proration and failed payments. We wire the billing provider to the entitlements inside the product, so what a customer pays for is what they can actually use.

Sign-up, roles and permissions

Sign-up, invites, SSO where it is needed, and a role model that survives your first enterprise customer asking for read-only access. Built once, rather than patched per account later on.

Admin and support tooling

Your own team needs to see tenants, correct data and answer a support ticket without a developer. We build the internal side of the product, not only the screens a customer sees.

Release, monitoring and rollback

Environments, automated deploys, feature flags and a way back. Shipping weekly to live customers only works if a bad release can be pulled before anyone raises a ticket about it.

How it runs

Plan. Build. Run.

01

A 30 minute call

You describe the product, the customers you have or expect, and the date that matters. We tell you what we would build first and where the risk sits. No deck, and no invoice for discovery.

02

Fixed scope, timeline and price

We write down the first release: screens, tenancy model, billing behaviour and integrations, with a timeline and a price against it. You approve that document before any code is written.

03

Build in the open

Short cycles, with a working environment you can log into throughout. You see the product every week rather than at the end, so a wrong assumption costs days instead of the whole build.

04

Launch, then run

We put it live, watch it under real use, and fix what the first weeks expose. Most clients keep us on a monthly retainer for monitoring, fixes, security updates and the next set of features.

Why infoloop

We do not hand over and leave.

  • We run what we buildThe same team that ships the product keeps it alive: monitoring, fixes to agreed response targets, security updates and a monthly report. Nothing is handed to people who have never seen it.
  • Tenancy decided before codeSeparating tenants later means a migration under load with paying customers on the system. We make that call at the start and write down the reasoning, so version two is not a rescue job.
  • Built to be operatedAdmin tools, audit trails and logs are in the first release, not a project for next year. Your support team should be able to answer a customer without escalating to an engineer.
  • One price, agreed up frontScope, timeline and price are fixed before the build starts. If you want something outside it, we re-quote in writing rather than letting a variation appear quietly on an invoice.
  • Judged on what is live50+ products shipped across six countries, a 4.8 average client rating, and 99.9% uptime on the systems we run. We would rather be measured on running software than on a portfolio.

What you get

Every engagement includes these, in writing, before work starts.

  • A working multi-tenant application, live on your infrastructure or ours
  • The tenancy and data separation model, written down and diagrammed
  • Billing wired to plans, seats and entitlements, with failed payments handled
  • Sign-up, invites, roles and permissions, plus SSO where you need it
  • An internal admin console for your support and operations team
  • Deployment pipeline, environments, monitoring, alerts and a rollback path

Who this is for

Three situations where this is the right call.

Paying customers on a prototype

The first version was built to prove the idea, and it worked. It now struggles at month end, every customer shares one set of tables, and adding a plan needs a developer. You need the version that scales without a rewrite you cannot afford.

Internal software you now want to sell

Something you built to run your own operation is being asked for by other firms. Before it can be sold rather than lent out it needs tenancy, sign-up, billing, support tooling and a team that can carry a release schedule.

Funded, with a first release due

There is a date, a small team, and a board expecting a product rather than a demo. You need people who ship into production rather than into a sandbox, and who are still there when the first hundred customers arrive.

Proof

Software we built, and still run.

Questions

What buyers ask us first.

What does a SaaS build cost, and how do you price it?
We do not publish a figure, because a first release for a two-role internal tool and a first release for a billing-heavy platform are different pieces of work. The shape is always the same. A 30 minute call, then a written scope with a fixed timeline and a fixed price, before anyone writes code. You approve that document and it does not move unless you ask for something outside it, in which case we re-quote in writing. Running the product after launch is a separate monthly retainer.
How long does the first release take?
You get a date in the scope document rather than a range on a web page, because the honest answer depends on how much the product has to do on day one. Two things move it most: how many roles and permissions exist, and whether billing has to handle upgrades, proration and failed payments from the start. We will usually propose cutting the first release smaller than you expect, put it in front of real customers, and add the rest once you know which parts they actually use.
Should every customer have their own database, or share one?
It depends on who you sell to. A shared schema with a tenant key on every row is cheaper to run, simpler to migrate and fine for most products. A database per tenant costs more to operate but answers the procurement question from regulated buyers, and lets one large customer be moved or restored on its own. We decide this before the build, write down why, and design the data access layer so the boundary is enforced in one place rather than remembered in every query.
What happens after launch?
The team that built the product moves onto a monthly retainer and runs it. That means monitoring and alerting, fixes to agreed response targets, security and dependency updates, small improvements each month, and a written report of what happened and what we recommend next. You are not handed a repository and left to recruit. If you would rather take it in house at some point, we will hand over documentation and work alongside your engineers until they are comfortable.
We already have a codebase. Do you rebuild it or work with it?
We start by reading it. A prototype that is slow or messy but structurally sound is usually worth keeping, and the work becomes tenancy, billing, permissions and a deployment pipeline around what exists. A rewrite is only worth it when the data model cannot be separated per tenant, or when the framework is unsupported. We tell you which of those we think you are in, with the reasoning, before we quote. Rewrites are quoted as rewrites, never started quietly under maintenance.
Who owns the code and the infrastructure?
You do. The code sits in your repository, the cloud accounts, billing provider and domains are in your name, and we work inside them. There is no proprietary framework you have to keep paying us to touch, and no hosting arrangement that only we can administer. If we stop working together you keep everything running, with the architecture notes, environment setup and runbooks we wrote along the way. We would rather be kept because the work is good.
