Legacy ERP Replacement
VB6, FoxPro, AS/400, a DOS-based system, or an off-the-shelf ERP that no longer fits — Slingr replaces it with a custom platform built around your operation, migrated without stopping the business, and owned by you.
Where to start
Whatever you're replacing, the model is the same: own the result, migrate on a glide path, pay no per-seat tax.

The glide path
Stand up the new platform alongside the legacy ERP and connect what stays. No rip-and-replace.
Migrate module by module, validating data against the source system at every step.
Retire the legacy ERP once financials cut over. You keep the data and own the platform.
Questions buyers ask
Slingr replaces an aging or off-the-shelf ERP with a custom platform modeled on your operation, migrated module by module on a glide path so the business never stops. You own the source code and data.
No. We surround the legacy system, substitute it module by module (purchasing, inventory, production, financials), then sunset it once you're live — no big-bang cutover.
Those are per-user platforms you license and customize through a partner. Slingr builds a system you own outright, shaped to your processes, with no per-seat tax.
It varies by scope, but AI-accelerated delivery typically runs months rather than the multi-year timelines of traditional ERP projects, at roughly 50-60% of the cost.
Describe what you run on today and get a budgetary scope back the same day — module breakdown, glide path, and the right pod. Whether or not you build with us.
