Systems many people rely on at the same time.

Long-lived internal systems with permissions, audit trails and integrations.

In enterprise software the key question is often responsibility rather than features: who changed what, and when? We build systems that stay changeable for years through modular structure, detailed authorisation and traceable records.

Problems businesses run into

What we often find

  • Who did whatWithout a trail of changes, the source of an error cannot be found.
  • Systems people fear changingTouching old software causes a new failure every time.
  • Scattered permissionsAccess for departed staff can remain open.

What we propose

Our approach

  • Modular architectureEach business area has its own module with boundaries defined in code.
  • Audit trailCritical actions are stored with who, what and when.
  • Roles and two-factor authenticationAdmin accounts are protected by an extra layer.

What we do

  • Admin panels

    Including invitations, roles and session management.

  • Stock, order and finance modules

    Movement-based records that can be traced backwards.

  • Background jobs

    Queue-based, retryable processing.

  • Single sign-on and corporate identity

    Sign-in with your identity system and central account management.

  • Approval chains

    Approval flows that vary by department and amount.

  • Reporting and export

    Management reports and data output for accounting.

Where it helps

  • Operations centres

    Several teams processing the same data.

  • Renewing legacy systems

    Modernisation through staged migration.

  • Multi-warehouse and multi-channel setups

    Stock and orders kept consistent across channels.

  • Purchasing and request management

    Tracking the path from request to approval and order.

Technologies we use

  • NestJS
  • PostgreSQL
  • Redis
