WORKFLOWS / INVENTORY INTEGRATION

Integrate manufacturing inventory systems without replacing the legacy ERP

Inventory does not need another place to be entered. It needs one change to reach every system that depends on it. We build the integration layer between the legacy ERP, warehouse workflow, and procurement process so people reconcile exceptions instead of entire datasets.

IN PRACTICE

A system built for a regional manufacturer.

We connected a manufacturer's legacy ERP, warehouse management system, and procurement workflow through an Azure Functions integration layer instead of replacing the existing systems.

What these results measure

The published case reports 89% less manual data entry and inventory reconciliation within hours rather than weeks. Its approach section describes individual system updates arriving within minutes; that is a different step from reconciliation. It also reports $180K annual savings from reduced overstock carrying costs. The source does not give the measurement period or calculation method for these results.

Where the work
gets stuck.

Warehouse staff update the WMS, then send the same information to procurement.
Procurement maintains a spreadsheet because the ERP does not reflect the current count.
Discrepancies surface days later, after a purchasing or stocking decision has already been made.
Replacing the legacy ERP would cost more and disrupt more than connecting it.

Manual reconciliation becomes the system of record

When three systems disagree, the spreadsheet maintained between them becomes the only place that explains the differences. The business starts depending on a person to keep its inventory state coherent.

Replacement is not the only integration strategy

A legacy ERP can remain the operational backbone while an integration layer translates its data for the WMS and procurement workflow. Modernization does not have to begin with a disruptive rip-and-replace project.

What we build.

Connect the tools you use.
Keep the context and the review path.

Legacy ERP and WMS bridge

Custom middleware translates the ERP's existing format and the warehouse system's API into a shared inventory model.

Azure Functions

Event-driven triggers process inventory changes without requiring either operational system to be replaced.

Message queue

Updates move between systems that run on different schedules, so one slow connection does not stop the rest of the workflow.

AI reconciliation

A reconciliation model continuously compares the systems, automatically resolving minor discrepancies and flagging significant ones for human review.

When we would
recommend waiting.

One system already owns every inventory change and the others can be retired. Consolidation may be simpler than an integration layer.
Product identifiers and units do not match across systems. Define the shared inventory model before automating synchronization.
The legacy system has no stable export, API, or event source. Establish a reliable connection before promising real-time updates.

Questions about this workflow.

Do we have to replace our legacy ERP?

No. The published manufacturing engagement kept the legacy ERP and connected it with the WMS and procurement workflow through a translation layer.

Can a procurement spreadsheet be part of the integration?

Yes, when its fields and ownership are defined. The integration should turn it into a structured input or output instead of leaving it as a separate manual reconciliation process.

How do systems with different update schedules stay in sync?

An event-driven workflow and message queue can buffer and route changes between systems without assuming that every connection updates at the same speed.

What happens when inventory counts disagree?

The reconciliation layer compares data across systems, automatically resolves minor discrepancies, and sends significant differences to a person for review.

How do we get a build quote?

Show us how one inventory update moves across the ERP, WMS, and procurement process. We will scope the integration layer and quote the build.
