Types of Automation Integrators
How Different Integrators Support Warehouse Growth
If you’re planning a warehouse automation project, selecting the right type of automation integrator is one of the most important decisions you’ll face. While some companies explore handling integration internally, the complexity of modern systems often calls for an experienced partner. That’s where automation systems integrators step in.
From independent consultants to full-service automation system companies, OEMs, and software-focused specialists, each brings different strengths. Understanding your needs and the roles of these providers can help you make an informed, strategic decision.
Understanding System Integration in Warehouse Automation
Ten years ago, warehouse system integrators were less common and not widely understood beyond large-scale operations. Today, they play a central role in how businesses evaluate, implement, and support complex warehouse automation.
Whether launching a new greenfield site or retrofitting an older facility, it’s worth learning the distinctions between the four major types of automation system integrators before locking in your next project partner.
1. Consultant Integrators
Consultant integrators typically enter the picture early. They help develop long-range supply chain strategies, guide network planning, and align automation initiatives with broader business goals.
Because consultants are usually vendor-agnostic, they provide unbiased guidance. Many are engaged at the executive level, especially when there’s uncertainty around technology selection or capital justification.
Their core value lies in helping companies define success upfront. This can include preparing RFIs or RFQs for future system integration, forecasting ROI, or supporting facility design at a network level.
2. Traditional Warehouse Automation System Integrators (SI)
Warehouse automation system integrators are hands-on partners who turn strategy into execution. These firms design and manage full solutions, including mechanical equipment, software layers, installation, and post-go-live support.
Depending on the provider, they may be fully brand-agnostic or have preferred vendors and internal OEM capabilities. The best automation system integrators are the glue between your warehouse processes and the technologies that enable them.
Their scope often includes:
- Material flow analysis
- Equipment selection and sourcing
- Conveyor systems, AS/RS, and AMRs
- Controls engineering and PLC programming
- Operator training and long-term support
Because of their broad scope, these integrators are especially useful for facilities undergoing major changes in layout, throughput, or picking methodology.
3. OEMs (Original Equipment Manufacturers)
An OEM manufactures the core systems you may deploy, such as robotic arms, shuttle systems, or vertical lifts. Some OEMs provide internal integration teams, while others work alongside SIs or consultants to deliver a larger solution.
OEMs are a natural fit when your automation strategy is centered on a specific technology, or if your project involves upgrading a single process rather than a full facility overhaul.
However, OEMs typically focus on their own product lines. If your integration involves multiple systems from different vendors, or if coordination between software platforms is critical, an OEM alone may not be enough to manage the entire scope.
4. Software, Controls, and Component Integrators
Some integration partners specialize in warehouse automation system integration’s digital and controls side. These teams manage the logic, interfaces, and software layers that connect your equipment to your warehouse execution system (WES) or ERP platform.
They may also provide:
- PLC panels and control architecture
- HMI interfaces
- Robotics orchestration software
- Data integration with upstream systems
- Industrial networking and diagnostics
This type of integration is essential in increasingly complex automation environments. While they may not handle equipment procurement or layout, they’re often the key to making the entire system function cohesively.
How to Choose the Right Automation Integrator
Start by evaluating your internal capabilities. If your team lacks in-house engineering or automation experience, you’ll likely benefit from early-stage support from a consultant or full-service integrator. An OEM or software partner may be sufficient if you’ve already selected technologies.
Here’s a general guide based on project needs:
- For high-level strategy: Engage a consultant.
- For full facility buildout: Work with a systems integrator.
- For targeted upgrades: OEMs may offer the best direct value.
- For systems connectivity and logic: Lean on software and controls integrators.
Multiple providers will participate in many projects. It’s not unusual to start with a consultant, implement with a systems integrator, and rely on a software firm to tie everything together.
What to Ask Before You Commit
Once you’ve narrowed your options, vet each integrator with real project examples. Ask questions like:
Have you handled projects of a similar scale?
- What industries do you typically support?
- Do you offer service and support post-implementation?
- Who are your preferred technology partners?
- Can I speak with a reference?
Clarifying expectations up front helps you avoid delays or missed handoffs later. You’ll also want to understand where their expertise ends, and where they rely on outside vendors.
Ultimately, you want a partner that can grow with you. Whether you plan to add new automation zones, replicate success at other sites, or scale your operations over time, long-term relationships save time and improve continuity.
Consultant Trends: Greenfield and Brownfield Projects
More companies are bringing in consultants at the earliest stages, especially for greenfield and brownfield projects. Senior leadership often drives this, as they want to assess risk and validate business cases before committing to large capital projects.
This shift reflects a growing understanding that upfront strategy pays dividends later. With the right consultant and systems integration team, companies can avoid costly rework and navigate vendor selection more confidently.
Make the Right Call Early
The landscape of automation system companies continues to expand, but not every provider is right for every job. Know your operation’s strengths, identify gaps, and choose an integrator who complements those needs.
A good system integration partner doesn’t just install equipment—they guide you through planning, coordination, testing, and long-term support. That kind of alignment turns an automation project into a long-term performance advantage.
You’re not alone if you’re unsure which automation integrator is right for your warehouse project. The Warehouse and DC Solutions Network, part of the MHI Solutions Community, was built to connect operations leaders like you with trusted solution providers across every stage of warehouse automation.
Fill out the Solutions Network survey to be matched with MHI members specializing in system integration, automation technologies, and distribution center optimization. Whether in the early planning phase or ready to implement, you’ll get personalized support from vetted experts who understand your goals.
