Systems built for one company

Custom Software Development

Since 2023

Custom software development means building applications, internal systems and integrations designed around one organisation’s processes, where off-the-shelf products do not fit.

We build internal systems, web applications, workflow platforms and API integrations. NEA has been shipping production business systems since 2023.

What problem does it solve?

Some processes do not fit packaged software. Companies either bend the tool until the process breaks, or fall back on spreadsheets and manual steps.

How does it work?

The process is mapped, the data model and user flows are defined, and the system is delivered in increments. Connections to existing ERP, CRM and internal applications are built over APIs, with engineering support until the deployment is in production.

Supported workflows

  • Build bespoke internal systems and admin tooling
  • Ship web applications and workflow platforms that run business processes
  • Develop API integrations with existing ERP, CRM and internal applications
  • Add AI agents and automation on top of the delivered system

Who it is for

  • Operations and finance teams whose process does not fit packaged software
  • Companies building bespoke systems in sectors such as banking, retail and manufacturing
  • Organisations modernising internal systems and extending them with AI

Integration possibilities

Platforms commonly connected in custom software projects include:

SAP, HubSpot, Salesforce, Stripe, Shopify, Airtable, Microsoft.

Integrated with

When a human is needed

Wherever automation takes over, approval and audit steps are defined, and critical decisions stay with an authorised user.

Why businesses use it

The software fits the process rather than the other way round, and the same team builds both the custom system and the AI layer on top of it.

Frequently asked questions
