G&G Systems Design delivers a complete, integrated software package for distribution industries — designed and maintained on IBM iSeries since 1995. From inventory to labor claims, every module works together.
G&G Systems Design, Inc. was founded in 1995 with a focused mission: deliver reliable, professional software systems for businesses running IBM iSeries. We specialize in the distribution industry, where precision and uptime are non-negotiable.
Led by Hector Ladron de Guevara, our team brings deep hands-on experience with the IBM iSeries platform — from legacy RPG development to modern integrated workflows. We don't just understand the technology; we understand how distribution businesses operate.
Based in Las Vegas, Nevada, we serve clients who need a committed partner, not a revolving-door vendor.
Our proprietary package covers every critical function in a distribution operation — fully integrated on IBM iSeries so your data flows seamlessly across every department.
Real-time tracking of stock levels, locations, and movement. Maintain accurate inventory across warehouses with full visibility into quantity on-hand, on-order, and committed.
Manage customer invoicing, payment tracking, aging reports, and collections. Keep your cash flow healthy with accurate, up-to-date receivables processing.
Streamline vendor payments, invoice matching, and disbursement processing. Control outgoing cash with full audit trails and vendor management.
The financial backbone of your operation. Chart of accounts, journal entries, period-end closing, and financial reporting — all integrated with every other module.
Define product structures, assemblies, and components. Essential for kitting, light manufacturing, and distribution operations with complex product configurations.
Process customer orders from entry through fulfillment. Track order status, manage pricing and discounts, generate pick lists, and confirm shipments efficiently.
Create and manage purchase orders, track vendor deliveries, and receive goods into inventory. Maintain optimal stock levels with intelligent purchasing workflows.
Track and process labor claims tied to distribution operations. Capture time, costs, and productivity data to manage workforce efficiency and cost allocation accurately.
End-to-end architectural design of IBM iSeries software systems tailored to your business workflows and long-term needs.
Proactive and reactive maintenance for iSeries applications — ensuring continuous operation, performance, and issue resolution.
Full deployment and customization of our distribution software package to fit your specific business processes and data environment.
Responsive technical support for day-to-day iSeries operations — troubleshooting, training, and performance monitoring.
The IBM iSeries (AS/400 / IBM i) platform is among the most reliable enterprise computing environments ever built. Its integrated database, bulletproof security model, and exceptional backward compatibility make it the backbone of serious distribution operations.
Our entire practice is built around this platform. Every module in our distribution suite is native to IBM i — no translation layers, no compatibility workarounds. Just solid, performant software that runs the way the platform was designed.
When you work with G&G Systems Design, you get specialists who have built entire careers on IBM iSeries — not generalists trying to learn it on your dime.
