Custom Korber WMS Add-On Development — Reporting, Integration, and Workflow Extensions

Custom Korber WMS (formerly HighJump) add-ons solve three categories of problems that the standard platform can't: real-time warehouse performance dashboards that combine WMS data with ERP and TMS systems, custom workflow extensions for industry-specific processes like hazmat handling or lot-tracked serialization, and API integrations with platforms Korber doesn't natively support. If your warehouse operations team is exporting CSVs into Excel to build the reports your WMS should already produce, or manually keying data between Korber and your ERP because the out-of-box connector doesn't handle your transaction types, a custom add-on replaces that manual work with software that reads and writes directly through Korber's published APIs.

This page covers what custom Korber WMS add-ons include, how integrations work at the API level, what reporting gaps custom development solves, cost ranges, timelines, and the engagement process.

What custom add-ons can you build for Korber WMS?

Custom Korber WMS add-ons fall into three categories, each addressing a different class of limitation in the standard platform.

The first category is real-time reporting and analytics dashboards. Korber's built-in reporting runs on scheduled data extracts — not live warehouse data. A custom dashboard pulls directly from the Korber database through its API layer and combines that data with your ERP (SAP, Oracle, NetSuite, SYSPRO) and TMS (MercuryGate, BluJay, Oracle Transportation) into a single view. Warehouse managers see pick rates, dock-to-stock times, labor utilization, and order accuracy updated as operations happen — not in a batch report generated overnight.

The second category is industry-specific workflow extensions. Korber WMS handles general warehouse workflows, but many operations need processes the platform was never designed to support: hazmat compliance workflows with SDS document management, cold chain temperature logging with automated hold triggers, pharmaceutical lot tracking with full genealogy and expiry management, or multi-client 3PL billing with activity-based cost allocation. These workflows run as add-on modules that hook into Korber's transaction events — when a putaway, pick, or shipment occurs in Korber, the extension executes the industry-specific logic.

The third category is API integrations with systems Korber doesn't natively connect to. Korber has published connectors for SAP and Oracle, but many operations run ERPs and platforms outside that list. Custom integrations bridge Korber with NetSuite, Microsoft Dynamics, Sage, Acumatica, Shopify Plus, and industry-specific platforms. These are bidirectional — inventory adjustments in Korber propagate to the ERP, and purchase orders from the ERP create receiving tasks in Korber — with conflict resolution and error handling built into the sync layer.

How do custom Korber WMS integrations work?

We build WMS add-ons that read and write directly to the Korber database through its published APIs — not screen-scraping or CSV exports. The difference: real-time data that updates as warehouse operations happen, not a batch report that's stale by the time someone reads it.

Korber WMS exposes a REST API layer and supports event-driven webhooks for transaction triggers. Custom integrations use both. The REST API handles data reads and writes — inventory queries, order status updates, receiving confirmations. The webhook layer handles event-driven automation — when a shipment completes, the integration pushes the ASN to the ERP and updates the TMS tracking record.

The integration architecture follows a three-layer pattern:

1. Data access layer — authenticated connections to the Korber API with rate limiting, retry logic, and credential rotation. This layer handles all reads and writes to WMS data.
2. Transformation layer — maps Korber's data schema to your ERP's schema. A "location" in Korber might be a "bin" in your ERP, with different field names, formats, and validation rules. The transformation layer handles the translation without either system needing to change.
3. Orchestration layer — manages the sequence and dependency of operations. An inbound shipment receipt, for example, might need to: (1) confirm receipt in Korber, (2) update inventory in the ERP, (3) trigger a quality hold if the item requires inspection, and (4) notify the procurement team. The orchestration layer ensures all four happen in order, and handles partial failures gracefully.

Every integration includes a monitoring dashboard showing sync status, error rates, and data latency. When something fails — and in warehouse operations, network interruptions and API timeouts happen — the integration queues the transaction and retries automatically rather than silently dropping data.

What reporting gaps does custom development solve?

Korber WMS reporting has three structural gaps that affect most warehouse operations. Custom development solves all three.

The first gap is cross-system visibility. Korber reports on WMS data only. A warehouse manager who needs to see order-to-delivery cycle time — from ERP order entry through WMS picking to TMS delivery confirmation — cannot get that from Korber alone. Custom dashboards pull from all three systems and present the full picture. In warehouse operations we've worked with, this single capability — seeing the complete order lifecycle in one place — eliminated 6-8 hours per week of manual report assembly.

The second gap is real-time operational metrics. Standard Korber reports are generated on a schedule — hourly at best, daily in many configurations. A warehouse running two shifts needs pick rate data, labor utilization, and dock congestion metrics that update every few minutes. Custom reporting taps the API event stream to provide this without impacting WMS performance.

The third gap is exception-based alerting. Korber doesn't send alerts when KPIs breach thresholds — someone has to check the report. Custom reporting includes rule-based alerting: if pick accuracy drops below 99.2%, if dock-to-stock exceeds the 4-hour SLA, if a specific client's orders are running behind schedule, the system pushes a notification to the operations lead. The shift from pull-based reporting (go check the dashboard) to push-based reporting (the dashboard tells you) is where most of the operational improvement comes from.

How much does a custom Korber WMS add-on cost?

Cost depends on the add-on category and the complexity of your Korber configuration. The table below shows typical ranges across the three categories.

These ranges assume a standard Korber WMS deployment. Heavily customized Korber environments — modified database schemas, custom transaction types, non-standard API configurations — add 20–40% to both timeline and cost because the integration layer needs to account for deviations from the published API behavior.

Multi-category projects (for example, a reporting dashboard plus two API integrations) are scoped and priced as a single engagement. The discovery phase identifies which components share infrastructure — a common data access layer, shared authentication, overlapping data models — which reduces the combined cost compared to building each add-on independently.

What's the development process for WMS add-ons?

Every Korber WMS add-on project follows a four-phase process. The first phase is where most of the risk gets eliminated — before a line of production code is written.

Phase 1: Discovery (1 week)

We audit your current Korber WMS configuration, document the specific gaps causing operational problems, map the data flows between Korber and your other systems, and identify which Korber APIs are available in your version and deployment type. The output is a scoped technical proposal with architecture diagrams, a defined deliverable list, fixed timeline, and a cost estimate accurate to within 15%.

Discovery costs $3,500–$5,000. It is a standalone engagement — if the scoped proposal doesn't make sense for your operation, you walk away with the technical audit and owe nothing further.

Phase 2: Scoped Proposal

Based on the discovery audit, we deliver a proposal specifying exactly what gets built, how it integrates with your Korber environment, what the milestone schedule looks like, and the fixed price. No ambiguity about scope. No change orders unless you add requirements.

Phase 3: Build (4–12 weeks depending on scope)

Development happens against a staging instance of your Korber WMS — never production until the add-on is tested. We deliver working software in 2-week sprints with demo sessions at the end of each sprint. Your warehouse operations team sees progress throughout, not just at the end.

Phase 4: Deploy and Support

Production deployment includes a parallel run period where the add-on operates alongside your existing process. Once validated, the manual process is retired. Post-deployment support includes monitoring, bug fixes, and a retainer option for ongoing enhancements as your warehouse operations evolve.

How long does a custom Korber WMS project take?

Total project duration from first conversation to production deployment ranges from 5 weeks (a single reporting dashboard) to 16 weeks (a multi-component project with workflow extensions and multiple integrations).

The breakdown by phase:

The most common timeline bottleneck is access to a Korber staging environment. Operations teams that can provision staging access within the first week of discovery typically see projects complete 2–3 weeks faster than those that require IT approval cycles for environment access.

What integration patterns work for Korber WMS?

Different systems require different integration patterns depending on data volume, latency requirements, and how the target system handles inbound data. The table below shows the most common patterns for Korber WMS integrations.

The ERP integration pattern deserves specific attention because it is the most common and the most failure-prone. The scheduled reconciliation layer runs nightly and compares inventory counts, order statuses, and item master data between Korber and the ERP. When discrepancies appear — and they always do, because of timing differences, manual adjustments, and transaction rollbacks — the reconciliation identifies them, logs them, and either auto-corrects (if rules allow) or flags them for the operations team. Without this reconciliation layer, small discrepancies compound over weeks and become inventory accuracy problems that affect shipping and fulfillment.

When is a custom Korber WMS add-on the right choice?

A custom add-on makes sense when the gap between what Korber WMS does and what your operation needs cannot be closed by configuration, a Korber upgrade, or an off-the-shelf connector. Three signals indicate you've reached that point:

• Your team spends hours every week exporting data from Korber into Excel to build reports that combine WMS data with ERP or TMS data. That manual work is a symptom of a cross-system visibility gap that no Korber configuration change will fix.
• Your warehouse runs processes that Korber wasn't designed for — regulatory compliance workflows, multi-client billing, temperature-controlled inventory, or serialized lot tracking with full genealogy. These are industry-specific requirements that a general-purpose WMS will never natively support.
• You run an ERP, TMS, eCommerce platform, or industry system that Korber doesn't natively integrate with, and the workaround — CSV exports, manual data entry, or a middleware tool that drops transactions — costs more in labor and errors than an integration would cost to build.

If you're running into Korber WMS reporting and workflow limitations that are costing your operations team time and accuracy, a discovery engagement identifies exactly which gaps a custom add-on closes and which ones can be handled through configuration or process changes.

For a broader view of how custom software fills WMS and supply chain gaps across different platforms — not just Korber — the supply chain gap map covers the full landscape of where standard WMS platforms fall short and where custom development makes financial sense.

Operations that need a warehouse management system built from the ground up — rather than extending an existing Korber deployment — face a different set of decisions. That path makes sense when the platform itself is the problem, not just specific gaps within it.

Start with discovery. One week, $3,500–$5,000, and you'll know exactly what a custom Korber WMS add-on costs for your specific operation — no guesswork, no generic estimates.
