We Support the IBM i Applications Your Business Depends On.
RPG, COBOL, CL, SQL & ERP — End-to-End Application Care.
Delivered With Precision, Reliability, and Accountability.
Your ERP and core business logic on IBM i don't need a rebuild — they need a team that still speaks RPG, still knows your batch cycle, and answers when something breaks. Sumo Networks provides ongoing maintenance, fixes, enhancements, and upgrade support for mission-critical IBM i applications, so your systems stay stable without growing your internal headcount.
Trusted by: Banks, School Boards, Law firms, Manufacturing, Medical Labs, and Municipalities to get modernization right.
What's Included
Application support that's built to last, not just built to last today.
Critical IBM i applications need more than a break-fix contract. Sumo Networks combines day-to-day maintenance with the technical depth to plan enhancements, run upgrades, and keep documentation current — all without pulling your internal team off strategic work.
End-to-end application support
Maintenance, break-fix, enhancements, upgrades, testing, and documentation — handled by consultants who work in IBM i every day.
ERP and business system coverage
Support for BPCS, Infor LX/XA, JDE World, custom-built ERP, and homegrown RPG/COBOL applications running your operations.
Native IBM i language depth
RPG (free-form, ILE, and traditional), COBOL, CL, and SQL — skills that are increasingly hard to find in-house.
Flexible resourcing models
Dedicated or blended support aligned to how your team already works, scaled up or down as project load changes.
Industry-tested experience
Legal, education, municipal government, manufacturing, and distribution environments — sectors where downtime isn't an option.
Business process expertise
Coverage across order-to-cash, inventory, procurement, shop floor control, and the interfaces that tie them together.
Interface and integration support
Keep EDI, REST, and third-party integrations (shipping, e-commerce, finance) running as connected systems change around you.
Change control and documentation
Every fix and enhancement is logged, tested, and documented — so institutional knowledge stays with the system, not one person.
Security-aware delivery
Application changes are made with an eye on access control and audit trail, aligned to your existing compliance obligations.
Technical Coverage
The IBM i stack, end to end.
From the operating system up through your business logic and the tools that surround it.

Why It Matters
Stability isn't a maintenance cost. It's a business advantage.
When your IBM i applications are properly supported, the conversation shifts from "who knows this system" to "what should we build next."

- ✓Faster resolution when production issues surface
- ✓Continuous delivery without expanding your internal team
- ✓ERP and business logic knowledge that stays with the system
- ✓Faster turnaround when the business needs to change
- ✓Consistent performance across every legacy workload
