You have two systems that need to work together. They weren't built to.

highgrove connects systems that were never designed to talk to each other — across IBM i, cloud, ERP, web, hardware and third-party platforms. Cross-stack, not IBM-only.

Bespoke development and systems integration is highgrove's highest-margin and hardest-to-replace capability. Businesses come to highgrove with integration problems their platform vendors can't solve. highgrove solves them.

What bespoke development covers

Bespoke IBM i / RPG development

New applications and features in RPG (including ILE), COBOL and CL — written by engineers who know the platform.

Legacy code modification

Extending, fixing and modernising existing IBM i applications — without rewriting what doesn't need rewriting.

Cross-platform integration

Connecting IBM i, ERP, cloud platforms, web applications and third-party systems — APIs, message queues, file-based and real-time.

API & REST development

REST API design and development on IBM i and other platforms — exposing legacy data to modern applications.

Workflow-embedded development

Development integrated into document workflows, EDI pipelines, output management and automation chains.

Technology partner integrations

Integration with Cleo, IPLS, PrintBOS / PB Digital, PaperVision, ABBYY, Bartender and other highgrove-supported platforms.

Hardware integration — a genuine differentiator

Most IT companies stop at software. highgrove integrates IBM i and operational systems with physical hardware — factory-floor devices, production equipment and facility I/O. This is rare, operational, and in production at manufacturing clients.

In practice

30 years of bespoke integration at Magna Specialist Confectioners.

Mangrove ERP (written by highgrove), native IBM i EDI (IPLS), output management (PrintBOS), and physical hardware integration — all connected and running as a single operational environment for over 30 years.

ERP

Mangrove — written by highgrove

Manufacturing ERP built from the ground up by highgrove engineers. Not bought in, not resold — written.

Integration

ERP + EDI + output + hardware

All four integrated into a single operational environment. highgrove wrote the code that connects them.

Longevity

30 years in production

Not a pilot, not a proof of concept. 30 years of continuous operational use — evolving alongside the business.

Common questions

Things integration clients ask us

We don't use IBM i — can you still help?

Yes. highgrove's bespoke development capability is cross-stack. IBM i is a specialism — not a prerequisite. highgrove integrates cloud, ERP, web applications and hardware regardless of whether IBM i is involved.

How long does a project take?

It depends entirely on scope. highgrove can deliver small integrations in weeks and has maintained complex bespoke systems for decades. The conversation about timescales starts with understanding the problem.

Do we get the code?

Yes. Bespoke code written by highgrove for your environment is yours. highgrove can also maintain it under a managed service arrangement — the choice is yours.

Can you work with our existing developers?

Yes. highgrove often works alongside in-house development teams — adding IBM i depth, integration expertise or hardware capability that the internal team doesn't have.
