Modern warehouses weren’t built with simplicity in mind. Over time, systems get layered on top of one other—WMS, ERP, OMS, robotics, labor platforms, BI dashboards—each solving a specific need, none truly built to work together.
The result? A “Frankenstack.”
Disconnected tools. Inconsistent data. IT is scrambling to keep things online. Ops is struggling to get a clear view of what’s actually happening on the floor. Both teams are discovering that the disjointed system creates disjointed decisions, and there is a need for a single source of truth.
Warehouse execution system (WES) software is emerging as the layer that can unify the warehouse tech stack. It doesn’t replace your warehouse management system (WMS) or enterprise resource planning (ERP) software.
A WES works alongside them to unify the stack, turn disconnected tools into coordinated workflows, and give both IT and operations a consistent view of what’s happening and what needs to happen next.
1. The Frankenstack problem and why unification matters
Warehouses today have a maze of overlapping systems—WMS, ERP, order management systems (OMS), robotics platforms, labor tools, and business intelligence (BI) dashboards. Each was designed to solve a specific function. Few were designed to work together. And most weren’t built to evolve alongside modern automation.
The result is what many IT teams now refer to as a Frankenstack — a mishmash of disconnected systems, custom scripts, and one-off workarounds, held together by tribal knowledge and constant maintenance.
IT teams spend their time troubleshooting fragile connections and patching together data that never quite aligns. Operations teams struggle to get real-time visibility into fulfillment. And every time a new tool is added, especially as automation is introduced in phases, the cracks get wider.
Manual and automated processes now run side by side, but without a way to coordinate them in real time, efficiency breaks down. Data becomes unreliable. Scaling becomes risky. And the warehouse becomes harder, not easier, to manage.
What’s missing isn’t another tool. It’s a unifying layer. A way to bring systems together, standardize workflows, and orchestrate execution—without rebuilding the entire stack.
2. Why the WES is the ideal platform for unification
The WES offers the connective platform that modern warehouses need. It’s not just another tool in the stack, but the layer that makes the entire stack work together.
What positions WES for this role is where it sits — between business systems and execution technologies. It receives high-level directives about orders, labor availability, inventory data. The software then translates them into real-time decisions: what to pick, when to replenish, who or what should do it, and in what order.
A well-integrated WES doesn’t replace your existing systems. The software connects them. It pulls information from your WMS, ERP, OMS, labor management system (LMS), and automation platforms. In addition, the WES can orchestrate workflows across them and pushe structured data back to keep everything aligned.
The WES also closes the loop between planning and execution, without introducing more complexity.
But the most transformative role of a WES is this: It becomes your system of action.
This is the platform where your operations team actually works. It’s the interface where task flow, inventory movement, labor coordination, and automation control all come together.
Teams can use a WES to monitor live activity, manage labor through integrated LMS tools, access real-time inventory data, and power BI dashboards with consistent, up-to-date information.
This is what inVia Logic is designed to be: a warehouse intelligence platform that brings orchestration, visibility, and control into a unified system, built to integrate deeply and scale with your operations.
3. What WES needs to truly unify the stack
While WES has the potential to unify the warehouse tech stack, not every platform is built to handle that role.
To truly simplify complexity and bring disconnected systems into alignment, a WES needs more than task dispatching. It must function as an operational backbone—resilient, intelligent, and deeply integrated.
Here’s what that looks like in practice—and how inVia Logic delivers
a. Seamless integration across the tech stack
A WES is only as good as the data it receives, and that depends on how well it integrates with the systems around it. The first and most critical requirement is easy, reliable integration that doesn’t drain IT resources or require constant rework.
inVia Logic uses inVia Connect to make that possible. It’s a flexible integration tool that supports a wide range of protocols—HTTP, FTP, SQL, CSV, and more—so you can mix and match technologies based on your existing stack.
Instead of requiring upstream systems to change, inVia Connect adapts to them. It allows IT teams to integrate quickly without custom builds or brittle interfaces, enabling inVia Logic to plug into your environment and start orchestrating execution from day one.
b. Real-time decision-making and dynamic task 0rchestration
A WES doesn’t just track what’s happening—it decides what should happen next. To truly unify execution, it must take in live operational signals—order volumes, service-level agreement (SLA) deadlines, inventory availability, labor status—and translate them into coordinated action across the warehouse.
inVia Logic uses real-time operational data to prioritize and assign tasks. It continuously prioritizes and routes tasks in real time, dynamically balancing work across autonomous mobile robots (AMRs), manual labor, replenishment, and picking stations. It eliminates idle time and batching delays by creating a continuous, responsive task flow. And it goes further.
inVia Logic can generate a centralized decision plan—determining who should do what work when. It can also schedule tasks for all warehouse resources, including third-party automation.
Whether you’re using an automated storage and retrieval system (ASRS), conveyors, robotic palletizers, or goods-to-person (G2P) systems, inVia Logic acts as the conductor. It makes sure all systems are working in sync, on the right priorities, at the right time.
c. Data normalization and visibility
Unifying systems only works if you unify the data. Disconnected tools often mean disconnected insights. Each system reports its own version of performance, inventory, and status.
A WES must normalize this data into one consistent, trusted view of what’s happening, what’s delayed, and what’s next.
inVia Logic delivers real-time visibility by centralizing task and inventory data from across WMS, ERP, robotics, and labor systems—thanks to integration via inVia Connect.
Once the data flows in, inVia Logic provides a unified operational view through customizable dashboards and reporting tools, giving both IT and operations teams a consistent source of truth.
Using built-in AI and business intelligence tools, inVia Logic continuously collects and analyzes thousands of data points per worker, robot, and SKU. It identifies inefficiencies, flags anomalies, and helps teams pinpoint whether an issue lies in the system, labor process, or inventory itself.
d. Labor management, built into execution
As warehouses evolve, labor management can’t stay siloed. The same system that orchestrates execution should also help optimize the people doing the work.
That’s why inVia Logic incorporates labor planning and performance tools directly into the execution layer. When task orchestration, zone activity, and workforce insights all live in one platform, labor optimization becomes real-time and continuous, not just historical reporting.
WES: the platform pulling the entire warehouse together
Warehouses don’t need more tools—they need one platform that can bring the existing ones together. A well-designed WES doesn’t replace your systems—it unifies them. It bridges business logic and floor execution, connects people and machines, and turns fragmented processes into coordinated action.
As complexity grows, the future of warehouse operations will belong to platforms that not only integrate but also orchestrate, adapt, and improve in real time. That’s the role WES is now ready to play.
“Warehouses today are increasingly complex, with multiple systems operating in silos,” said Lior Elazary, co-founder & CEO of inVia Robotics. “At inVia Robotics, we believe a warehouse execution system should serve as the intelligence layer that unifies these systems and drives real-time decision-making.”
“Through deep integration, inVia Logic WES becomes a single source of truth — a command center that empowers warehouse managers to move beyond task coordination and into a more strategic role, shaping efficient, scalable operations,” he added.
