Custom Development
Web applications, customer portals, and the integration layers that connect them to your ERP and CRM — built on frameworks your team can maintain.
Software built for the gaps standard products leave
Not every requirement fits inside SAP, Oracle, or Dynamics standard functionality — and not every problem needs an ERP at all. We build custom web applications, portals, and integration services for exactly those gaps.
Every build follows the same architecture discipline we use on ERP integrations: external systems sit behind an adapter layer, content is decoupled from code, and nothing ships without documentation and a handover plan.
- Customer and partner portals with authentication and role-based access
- Internal tools and dashboards for teams standard software doesn't serve well
- API and middleware development connecting existing systems
- Legacy application modernization and re-platforming
What's included
Web Applications
Custom web apps built on React, Next.js, or your team's preferred stack.
Customer & Partner Portals
Authenticated portals for quotes, orders, tickets, or account management.
API & Middleware
Integration services connecting your ERP, CRM, and third-party platforms.
Legacy Modernization
Re-platforming ageing applications without losing the business logic inside them.
Security by Default
OWASP-aligned coding standards and access control on every build.
Documented Handover
Full source code, architecture docs, and training so the team you have can maintain it.
Why build custom with DADynamics
We only recommend custom development when standard products genuinely don't fit — and we build it so it doesn't become next year's legacy problem.
- Architecture reviewed against maintainability, not just feature speed
- Every integration isolated behind an adapter so vendor changes don't break the app
- Fixed-scope milestones with acceptance criteria agreed up front
- Full intellectual property and source code transfer at completion
How we get there
A structured path from discovery to a supported go-live.
- 01
Scope
Requirements, technical discovery, and a signed-off architecture.
- 02
Design
UX wireframes and a component design system reviewed before build.
- 03
Build
Sprint-based development with a shared, client-visible backlog.
- 04
Launch & Support
Testing, deployment, documentation, and a defined support window.
Where this fits
Corporate Customer Portal
A branded portal giving corporate customers self-service access to orders, invoices, and support.
ERP Gap-Fill Tool
An internal tool covering a workflow the ERP handles poorly, integrated back into it via API.
Legacy App Re-Platform
A decade-old internal application rebuilt on a modern, maintainable stack.
