SaaS & Enterprise Software Development

What we build for SaaS & Enterprise

The defining question in SaaS is asked once and answered forever: what does the second customer cost you. If onboarding them means a branch in the code or a separate deployment, you have built bespoke software with a subscription attached to it.

SaaS software development is therefore mostly decisions taken very early. How tenancy is isolated, how a customer’s data is separated, how configuration differs from customisation, and what happens when the largest account wants something that would harm everyone else.

Most of what we are asked about here is one of two situations: a product that grew out of an internal tool and now has customers, or a first version that sold better than expected and cannot take a third region. We have no published SaaS case study.

Sector constraints

What makes this sector hard

Tenancy is decided once

Whether tenants share a database, a schema or nothing shapes every query, migration and backup afterwards. It is the hardest decision to reverse.

Onboarding is a feature

How fast a new customer reaches value decides churn more than the feature list does, and it is usually the least-designed part of the product.

Enterprise buyers audit before they buy

Single sign-on, roles, audit logs and data export are what procurement asks for. Adding them under deadline is how dates slip.

Every customer is on a different version of your assumptions

Old accounts carry old data shapes. Migrations have to work on the messiest tenant, not the newest one.

What we build for this sector

Multi-tenant platform build

Tenancy, permissions and data isolation decided before the first feature, because they are painful to change once customers are live.

Onboarding and self-service

Signup, provisioning, billing and the first-run experience. The part that turns a trial into a customer.

Enterprise readiness

Single sign-on, role-based permissions, audit logging and data export, built before procurement asks rather than after.

Infrastructure and deployment

Environments, release pipelines and monitoring, so shipping is routine instead of a scheduled event.

Capabilities this usually needs

Questions we get asked

We already have a product. Can you take it further?

Yes, and it is the more common request. We start with an audit of the code, the data model and the deployment process, then give you a written view of what is safe to build on and what needs replacing first. That comes before any feature quote, because quoting features on top of a foundation nobody has looked at is how estimates become fiction.

How do you decide the tenancy model?

From how your customers actually differ, not from preference. Shared schema is simpler and cheaper until a customer needs their data physically separate or a schema of their own. If that is anywhere on the roadmap, designing for it now costs far less than migrating to it later, and we will tell you which side of that line you are on.

Can you work alongside our in-house team?

Often the best arrangement. We take one service, one layer or one hard problem while your team keeps shipping the rest. Which split works depends on where your team is already strong, so it is worth deciding deliberately rather than defaulting to handing over everything or nothing.

Tell us the constraints you are already aware of. Half of scoping a sector project is working out which of them are real and which are assumed.
