Custom SaaS Engineering

Tech Team 4U

SaaS built around how your customers actually work

MVPs, multi-tenant platforms, web apps, CRMs and the integrations that connect them. Each service below goes deeper into one part of the build.

Let’s Talk
Let’s Talk

Start and Validate

A first release focused on the workflow that proves customers will pay, built on code you can grow.

Scale the Platform

Tenancy, subscription billing, roles and usage limits for a product that has moved past its first customers.

Connect the Business

Internal CRMs and API integrations that keep sales, billing and support data in one place.

How we engineer SaaS

Tenancy decided early
How customer data is separated is settled first, because it is the hardest thing to change later.
Billing that fits pricing
Plans, trials, seats and usage are modelled so a pricing change does not mean a rewrite.
Roles and audit logs
Permissions and activity history are built in, which is what larger customers ask about first.
Built to hand over
Documentation, tests and CI come with the code, so an in-house team can take it forward.
