Custom Development

Sage X3 Custom Development

Sage X3 custom development by senior 4GL developers — built to last and easy to maintain.

Sage X3 is highly extensible, and most mid-market deployments need some custom development — a custom screen, a specialized import, a workflow rule, or a process automation that standard functionality does not cover.

PRH Consulting's development practice is led by senior Sage X3 4GL developers who write code that is documented, performant, and maintainable. We treat custom development as a long-term asset, not throwaway work.

Problems we solve

  • Standard Sage X3 functionality that doesn't quite fit your process
  • Inherited 4GL code no one understands or wants to touch
  • Slow or unstable custom screens, reports, or imports
  • Manual workarounds that should be automated
  • Specifications that never quite get implemented correctly

What we deliver

Personalized entry screens, custom workflows, and approval routings that match the way your team actually operates.

4GL development

Senior 4GL programming for business rules, validations, automations, and Sage X3 extensions.

Custom reports & inquiries

Crystal Reports, SEI dashboards, and Sage X3 inquiry screens built for the people who will actually read them.

Custom import templates, scheduled exports, and integration helpers with reconciliation and exception handling.

Code refactoring

Cleaning up inherited custom code so it's documented, supportable, and faster.

Our approach

Built to be supportable

Every customization is documented, version-controlled, and reviewed — not written and forgotten.

Standard first

We use standard Sage X3 functionality whenever it fits. Custom code is a deliberate choice, not a default.

Senior developers only

Sage X3 4GL is a specialized skill. Our developers have years of production experience.

Outcomes you can expect

  • Custom development that survives staff turnover
  • Faster, more reliable custom screens and reports
  • Documented code your team or your next partner can support
  • Process automation that eliminates manual work

Frequently asked questions

Will custom development survive Sage X3 upgrades?

Yes, when written correctly. We follow Sage X3 customization best practices so upgrades are predictable and re-testing is minimal.

Can you take over existing custom code?

Yes. We frequently inherit 4GL code from other partners or internal developers, document it, and stabilize it.

Do you do custom mobile or web extensions?

Yes — including custom web services, mobile entry screens, and integrations with external web and mobile applications.
