Why integration beats rip-and-replace
The instinct when a warehouse underperforms is to replace the system. The faster, cheaper path is usually to get more from the WMS you already run.

Rip-and-replace is the expensive answer
A new warehouse management system is a multi-year program: migration, re-integration with your TMS and ERP, retraining, and a risky cutover. By the time it goes live, your lanes, clients, and SKUs have moved. Most of the capability you paid for sits unused because the rollout, not the software, is the bottleneck.
Most of the value is already installed
Manhattan, Blue Yonder, SAP EWM, and Korber are capable platforms. The gap is rarely the software. It is slotting that has drifted from current velocity, pick paths and wave planning that were never tuned, and manual exception handling that eats throughput.
InfoSun re-slots against live demand, tightens waves and labor management, integrates cleanly with the systems around the WMS, and adds human-supervised AI agents for receiving and exceptions. No migration, no lock-in.
- Re-slot inventory against current velocity to cut travel time.
- Tune wave planning and labor management for throughput.
- Automate receiving and exception handling under human supervision.
- Integrate the WMS with TMS and ERP so data agrees.
Faster time to value
Optimizing the platform you own delivers results in quarters, not years, and protects the investment you already made. Typical outcomes include 99%+ inventory accuracy and 20-35% more productivity from the existing system.
- Rip-and-replace is slow, risky, and often unnecessary.
- The gap is usually slotting, waves, and manual exceptions, not the software.
- Extending the WMS you own delivers results in quarters, with no migration.
- Integration keeps your TMS and ERP data in agreement.
Usually no. Most warehouses leave capability unused in the WMS they already run. Re-slotting, wave and labor tuning, clean integration, and supervised automation lift accuracy and throughput without a migration or a multi-year build.
InfoSun is platform-agnostic and works with the WMS you already run, including Manhattan, Blue Yonder, SAP EWM, and Korber. We build on and operate the platform rather than replacing it.
