IBM i / AS/400 / iSeries Specialists
Some of the most important business systems in North America still run on IBM i — and the pool of engineers who can operate, extend, and modernize them keeps shrinking. We’ve been in this platform since it was called AS/400, and we bring that depth to SMB and midmarket clients who can’t easily hire it in-house.
Why Networks One
The IBM midrange platform — AS/400 in 1988, iSeries in 2000, System i in 2006, IBM i today — has quietly kept running the most demanding ERP, distribution, banking, and manufacturing systems in the world. And it’s not going anywhere: IBM keeps advancing the Power hardware, the OS, and DB2 for i on a multi-decade cadence.
What is going away is the workforce that knows how to run it. The engineers who built these systems in the ‘90s are retiring, and the tools they used aren’t taught in most CS programs. Our clients — especially SMB and midmarket — frequently find themselves unable to hire an IBM i admin at any reasonable rate.
That’s where we come in. We’ve been operating and developing on this platform continuously since the AS/400 era, and we deliver that expertise on a fractional or managed basis so you don’t need to staff it internally.
What We Do
From keeping your existing IBM i healthy to putting a modern web/mobile face on a green-screen application — we cover the whole platform.
Day-to-day IBM i operations: user & group profiles, subsystem tuning, work management, BRMS backup strategy, PTF planning, journaling, HMC and LPAR management, and disaster-recovery testing.
Every generation from RPG III on the AS/400 to modern Free-format RPG on the latest IBM i. New development, legacy maintenance, refactoring toward modular Free-format, and CLLE program design.
Native DB2 for i administration and development: physical & logical files, DDL, embedded SQL, stored procedures & triggers, journaling, MIMIX / iTera / Db2 Mirror replication, and performance tuning.
Put a modern web or mobile UI on a green-screen application — without rewriting the business logic. Screen scraping, refacing (Profound UI, Presto), or full API + SPA rebuilds. Your timeline, your pace.
Connect IBM i to the modern stack: REST & SOAP web services, MQ, Kafka, SFTP/MFT, EDI (X12 / EDIFACT), IFS file movement, and native adapters to Salesforce, SAP, Dynamics, and .NET.
Object-level authority review, exit-point auditing, user profile hygiene, single sign-on integration, encryption of data-at-rest, and audit-ready reporting for SOX, PCI, HIPAA, and internal audit programs.
Where IBM i Still Wins
IBM i earned its keep in the industries where the cost of downtime is highest and the ERP has been running for decades. Ours is deepest in the two verticals where that’s most true.
JD Edwards World / EnterpriseOne, Infor XA / ERP LX / M3, MAPICS, BPCS, and thousands of homegrown ERPs run production, MRP, order-to-cash, and warehouse operations on IBM i every single day.
Core banking (Fiserv Signature, DNA), credit unions, insurance policy administration, and trust systems — many still on IBM i because it’s the most reliable, auditable platform they’ve found.
Where Clients Start
Every IBM i client we take on has one of these problems. Sound familiar?
Modernization
You don’t have to rewrite thirty years of RPG to give your users a modern experience. We build the layer on top and expose the business logic through APIs — on your timeline, at your pace.
Modernization Without Migration
The green-screen application that has run your business for two decades is doing its job. The problem is the interface — not the logic. We put a modern web or mobile UI on top, expose the underlying programs and files through REST APIs, and let your team use a browser or phone while the reliable server-side logic keeps doing what it’s always done.
The result: fewer resignations, easier training, better data, and a system your recruits will actually agree to work with — without a multi-year ERP replacement project.
How We Engage
Almost every IBM i engagement follows the same arc — get healthy, then get modern, then stay that way.
Health check: OS & PTF currency, DR readiness, security posture, developer bench, and modernization opportunities. Delivered as a written assessment with a fixed-fee remediation plan.
Get current on OS releases, close audit findings, verify backups, exercise DR, and establish a change-controlled release process. Boring — and the highest-ROI 90 days you’ll spend.
UI refacing, API enablement, replication to modern BI, and RPG refactoring — delivered as short sprints so business value ships every quarter, not in a five-year program.
Fractional or fully-managed IBM i admin and development on retainer. Monthly SLA reporting, quarterly modernization review, and no more recruiter panic when your admin retires.
Why NOCG for IBM i
Enterprise IBM i depth — at SMB and midmarket engagement models.
