The Migration Story · Manufacturing
How an FDA-regulated U.S. manufacturer took back control of its software — replacing a monolithic ERP module by module, without ever stopping the line.

The Starting Point
Three modules in use. Four that mattered — not in the package at all. Meanwhile, on the production floor, output was reported as end-of-week guesstimates. Costing was opaque, and the lot traceability the FDA expects was something the system couldn’t deliver.
The Slingr Approach
No big-bang cutover. No data cleanup project before the real project. Each phase replaced one piece of the operation, proved itself in production, and only then did the next one start.
Parts, suppliers, purchase orders, and receiving went first — focused, custom-built, and synced live with the legacy system, which kept running untouched.
Lot traceability, BOMs, work orders, and costing moved onto real-time data — every lot traced, every location scanned, FDA 21 CFR Part 11 audit trails built in. Plus a 20-report suite the packaged ERP never offered. The operation went from reactive to proactive.
QuickBooks, WooCommerce, and payments came only once everything else was stable. Money moves last — when the systems feeding it are already proven.
Module by module. Core systems of record never disrupted. No data cleanup required first.
The Results
The legacy contract — including every paid-for, unused module — is gone.
Where Slingr Solutions Comes In
Slingr Solutions builds AI-accelerated custom software for the systems your business actually runs on — ERP, MES, scheduling, quality, inventory. The migration in this story is our standard playbook, not a one-off.
We start by surrounding the legacy system — building the missing pieces alongside it, not inside it. Then we substitute the modules that hurt, one at a time, each proven in production before the next begins. Only when nothing depends on the old system does it sunset.
AI-accelerated engineering pods ship production-ready software in two-week cycles. Discovery, design, build, and ongoing management are all AI-assisted — which is why a full ERP exit fits in about a year instead of three.
Packaged ERPs make your operation fit their modules. We build around how your production, scheduling, and quality processes actually run — including the four modules the package never had.
What this manufacturer owns now: applications, agents, and IP — running in a dedicated Google Cloud environment they can take anywhere. Thirty-plus refinements beyond the original scope have already shipped — new needs land in two-week sprints on software they own, not as another subscription. No per-seat licensing, no vendor lock-in, no paying for modules nobody uses.
Tell us which system is holding your operation back, and get a budgetary scope back the same day — no commitment, no discovery fee.
