Warehouse Management Software vs. ERP

Written by Fiona McGuinness | 13-Jan-2025 15:01:08

As a wholesale distributor, efficient warehouse operations are critical to your success. Warehouse management software (WMS) can help streamline operations, improve inventory accuracy, and reduce costs. But, what exactly is WMS, and how does it differ from an ERP system? This blog post will explain the key differences between these two types of software and help you determine which solution is right for your business.

 

Warehouse Management System (WMS): Custom tools to improve warehouse operations

A WMS is a software tool built solely to manage your warehouse operations. It automates the process from receiving stock to fulfilling customer orders. Designed to help your warehouse work better and make more money, the system provides tools for:

  • Receiving and put-away of inventory
  • Picking and packing orders
  • Shipping and tracking shipments
  • Managing inventory levels
  • Optimising warehouse layout

A WMS will also provide valuable insights into your warehouse operations, such as:

  • Inventory turnover rates
  • Order fulfilment times
  • Shipping costs

 

Enterprise Resource Planning (ERP) Systems: Your Business Command Centre

An ERP system, on the other hand, serves as the central nervous system of your business, unifying all operations into a single, comprehensive platform. While traditionally known for managing core business functions like financials, sales, and customer relationships, modern ERP solutions have evolved to include robust warehouse management capabilities.

Modern ERP systems will now seamlessly integrate:

  • Financial management and accounting
  • Sales and order processing
  • Customer relationship management (CRM)
  • Marketing automation
  • eCommerce operations
  • Supply chain management
  • Warehouse operations
  • Mobile solutions and more

 

Many modern ERP solutions include substantial warehouse management features such as:

  • Batch tracking for inventory traceability
  • Mobile solutions for the warehouse:
    • Integrated handheld scanning devices for full warehouse operations
    • Smartphone apps for quick warehouse tasks on the go
  • Product assembly and kitting management
  • Advanced replenishment for inventory optimisation
  • Returns processing
  • Matrix product management for items with multiple variants
  • EDI integration for streamlined documentation

The modular nature of today's ERP systems means you can start with essential features and expand functionality as your business grows. This scalability ensures your software investment evolves with your needs.

For businesses seeking to streamline their warehouse operations, modern ERP solutions like Intact iQ include these built-in warehouse management features. This integrated approach can eliminate the need for a separate Warehouse Management System (WMS), reducing complexity and costs while maintaining a single source of truth for your business data.

However, if your warehouse operations require specialised functionality due to complex processes, high volume, or specific industry requirements, you may benefit from a dedicated WMS. Many modern ERP systems can easily connect with specialised warehouse management software, giving you the best of both worlds - comprehensive business management from your ERP system alongside advanced warehouse capabilities from your WMS.

 

Is Your Warehouse Ready for an Upgrade?

Take a quick look at these signs. If any seem familiar, it may be time to upgrade your warehouse management capabilities.

  • You're frequently discovering stock discrepancies
  • Staff spend more time searching for products than picking them
  • Different systems aren't talking to each other
  • Order fulfilment is slower than you'd like
  • Customer complaints are on the rise
  • You're planning significant growth in the next few years

 

Integrated or Standalone: Which WMS Is Right for You?

When you're picking a system to help you run your warehouse, you've got two main choices: an ERP system with built-in warehousing functionality or a standalone WMS that integrates with your main system.

Built-in warehouse functionality in your current business software offers seamless integration - your warehouse operations are directly connected to your financial, billing, and inventory systems. This integration gives you real-time visibility into how individual products impact your bottom line, helping you make more informed inventory decisions.

A standalone WMS, while focused solely on warehouse operations, typically offers more sophisticated warehouse-specific features and detailed operational analytics. However, it won't handle accounting or financial tracking. Think of it as a specialised tool optimised for warehouse management rather than an all-in-one solution.

The key consideration is keeping your data in sync - if your separate warehouse system doesn't work well with your main business software, you'll end up with different sets of information that don't match up. This can lead to mistakes and make it harder to know what's really going on in your business when you need to make important decisions.

Modern ERP packages like Intact iQ increasingly include sophisticated standard and optional warehouse operation features, potentially eliminating the need for a separate WMS. However, for complex warehouse operations, integrating a specialised WMS with your main business software may be essential. Thanks to modern REST APIs, this integration is more straightforward than ever, allowing you to leverage the best of both worlds while maintaining data consistency.

 

Making the Right Choice for Your Business

When deciding between a standalone WMS or an integrated ERP solution, consider these key factors:

  • Future-Proofing Your Business - First, think about where your business is heading. If you're using several different systems that don't work together, it's hard to get a clear picture of how your business is truly doing.

 

An all-in-one system (ERP) with built-in warehouse features gives you this clear view and might have all the warehouse tools you need. If you anticipate more complex warehouse operations as your business grows, consider an ERP system that can seamlessly integrate with specialised warehouse management solutions.

 

  • Costs and Managing Change - Implementing an all-in-one system streamlines both costs and training - you're working with a single vendor and your team only needs to master one interface. Opting for a separate WMS means additional licensing costs and training requirements, as your team will need to become proficient in two distinct systems.

 

When considering a system upgrade, phasing the implementation is often the wisest approach. This gives your team time to get comfortable with each new system and causes less disruption to your daily work. It also makes training easier since your team won't have to learn everything at the same time.

 

  • System Communication - With an all-in-one system, all parts of your business talk to each other automatically - your warehouse, sales, and financial data stay perfectly in sync. While it's become easier to connect separate warehouse systems to your main business software thanks to modern technology, not every business system has this capability.

 When choosing your main business system, make sure it can connect with other software if needed. This gives you the flexibility to add specialised warehouse tools in the future without having to replace your entire system.

 

Understanding the Investment: Integrated vs Standalone

Standalone WMS systems focus only on warehouse operations. In contrast, modern ERP solutions like Intact iQ include warehouse management as part of a full business solution.

This means one system to maintain, one interface to learn, and seamless data flow across your entire business. And if you need specialised warehousing features later? Modern APIs make it easy to add them.

 

From Chaos to Control: Real Warehouse Success Stories

IFM Limited's (Industrial & Farm Machinery Limited) journey perfectly demonstrates how modern ERP systems can transform a growing business. Starting with two separate companies running independent systems, they needed a solution that would future-proof their operations - especially critical given today's supply chain challenges.

Their transformation unfolded in phases:

  1. First, they tackled branch operations, connecting their locations in a way that made inventory movement between branches seamless
  2. Next, they introduced their automated warehouse extension. Intact iQ now directs automated systems to bring inventory to pickers. This happens as they start their 6 am shifts.
  3. Most impressively, they integrated their OEM production facility through REST API technology, connecting their manufacturing operations directly with their warehouse systems
  4. They even equipped their sales team with mobile access to their back-office system, giving reps real-time visibility of inventory levels while on the road

What makes IFM's story particularly valuable is how they approached the implementation. Using a sandbox environment, they were able to train staff before going live, ensuring a smooth transition. After implementation, they focused on automating repetitive tasks, helping their team work smarter rather than harder.

East Coast Fittings has seen significant improvements since implementing Intact iQ's ERP software. Their IT Manager notes: "The speed at which Intact iQ can now process an order has added huge value to our business. We have identified further areas in our warehousing and logistics that Intact iQ features can add further value to our business." This demonstrates how modern ERP solutions with integrated warehouse capabilities can not only improve current operations but offer additional features that businesses can leverage as they grow.

While IFM’s story showcases implementation excellence, Uniboard's story demonstrates another crucial benefit - staff productivity. By improving their warehouse processes, they saved time. Their team could then focus on growing the business instead of handling manual tasks.

Zodiac Stainless Steel provides perhaps the most comprehensive example of what's possible. Their implementation resulted in optimised warehouse operations and inventory management, but more importantly, it enhanced their overall productivity. Their experience shows how improvements in warehouse management can create ripple effects throughout your entire business.

 

Common Concerns About Switching Systems

If you're worried about disrupting your current operations by implementing a new system, you're not alone. This is why modern ERP solutions like Intact iQ offer:

  • Phased implementations, as seen in IFM's journey
  • Sandbox environments for staff training before going live
  • Initial handholding for key milestones such as your first tax return
  • Continued support after implementation
  • The ability to start with core features and add more as needed
  • Flexible integration options through REST APIs if you need specialised features later
