Buying the best warehouse management software (WMS) will take the organization to a whole new level of growth through enterprise-grade inventory visibility, modern automation, and strategic order fulfillment. 

The “why” of implementing the best WMS software is easy. HOW to buy a WMS is often where companies run into misconceptions, costly surprises, and often stalled growth. This article will help you decide which WMS is best for your business when It’s Grow Time™.

Which WMS software is best?

Well, that depends on what you want to get out of it. Buying the right WMS for your business requires asking, “Do we want to simply harvest growth, or seed and nurture it?” Do you want to just react to problems or plant for the future?

What is a warehouse management system and aren’t all of them pretty much the same? Nope. While all WMS systems may seem similar, they are not. Their differences are hard to spot, yet heavily influential on your long-term growth. 

Most WMS software does a good job of fixing immediate problems to harvest the growth that’s out there now. The best WMS software is built from Day 1 to get you where you want to be in 10 years, with very minimal cost or disruption. That’s “planting” seeds for future growth. Spotting the difference often takes some costly lessons learned first. 

Confusing options, misleading noise from salespeople, hidden costs, unexpected maintenance, and features that you didn’t realize you would need later are common factors leading to regrets. 

Making the right decision requires digging deep into your unique requirements; the various types of WMS options; their capabilities, and benefits before making a decision.

Decisions to make before your WMS evaluation

Having the best WMS software is essential for growth. A dedicated WMS is designed to handle a variety of duties from automated pick-pack-ship and inventory tracking/syncing to supply chain analytics that drive critical decision-making on the floor. 

Defining your WMS requirements

What warehouse problems do you need to fix? Some warehouse management systems are basic. Others provide more capabilities than you’ll ever need. Most are great at fixing immediate problems; very few consider the specific issues that you didn’t see coming. Flexibility is

Start by deciding what you want to get out of your WMS. Are you just looking to fix immediate problems, like these – or do you need something more advanced?

  • Too many systems that don’t talk to each other
  • Slow (or NO) reliable inventory data
  • Manual or paper-based tasks that lead to errors
  • Too many orders and long fulfillment times 
  • High operational costs including labor & shipping 
  • Poor insights into staff performance or customer KPIs
  • Blind spots with extended partners like shipping carriers & EDI networks
  • Time & cost to onboard users or add custom functionality 
  • No integrated barcoding for order management system (OMS)

What about the future?

  1. Which of these issues put the biggest dent in your bottom line right now?
  2. What is the financial impact of NOT fixing them? 
  3. Do you also need capabilities to get ahead of future growing pains? 

That opens another important discussion: what are the WMS options? 

Classes of WMS software tools

There are a variety of software tools that have a WMS software component to consider:

  • Standalone WMS tools
  • Best-in-class OMS + WMS integrated systems
  • Monolithic supply chain platform
  • Enterprise Resource Planning (ERP) with bolt-on or homegrown WMS functionality
  • Supply chain management analytics
  • WMS for 3PL warehouses
  • Cloud-based or on-premise WMS
  • Omnichannel fulfillment supply chain applications


That depends on where you want to be in 10 years. You may not require the capabilities of a full OMS suite right now, but wouldn’t it feel good to know those capabilities are within arm’s reach when you need them — without having to switch platforms?

If future growing pains are a concern, look for a warehouse management system that offers an easy bridge to advanced OMS and DOM (Distributed Order Management) capabilities that will come up later (usually under very tight time constraints and pressures). 

Not sure what is the difference between OMS and DOM? In a nutshell, you can’t have DOM without an OMS:

  • An OMS is the software that manages and tracks the entire order process.
  • DOM is an advanced portion of that system that allocates order fulfillment to the most optimal location.

Are you just managing logistics, or growing?

Will your company consider launching a direct-to-consumer (D2C) channel at some point? 

Right now, a basic WMS might be okay: “200 more orders a month? No problem. Bring it!” All of a sudden, those 200 become 2,000, then 20,000. Shipping costs start biting into your margins. Now, considerations like DIM weights, labeling compliance, peak season surcharges, free returns, and other things come into play.

Before you know it, you spend most of your time managing logistics instead of marketing your new channel. 

You’ll eventually need to introduce OMS capabilities to manage it all profitably, such as drop shipping, automatic order routing and allocation, and pre-ordering. But what will that transition look like with your technology partner? Will it require 100 developers? Or a 12-month project with the vendor and their consultants? 

If growth is in your future, opt for a WMS platform that’s made to add order management and DOM functionality at your own pace — With a predictable cost laid out upfront. 

Flexible WMS platform or monolithic suite?

Do you want to be a partner or just a signed contract?

Familiar names in warehouse management systems, particularly those built under a monolithic brand of many other products, often fail to address the distinct goals of one business from the next. They “check many boxes” on the surface. Likely they have some impressive awards and recognitions, too. 

But odds are, they’re riding the coattails of a tech giant. That name got their solution onto the analysts’ Top 10 lists, but it doesn’t mean their WMS is the best fit for your business.

The truth comes out in your RFP

Be prepared and dig in deep. Ask the right questions during your WMS RFP. Lean into available WMS software selection tools that unearth the true differences between modern warehouse management systems and legacy suites that are outdated, or cobbled together from an acquisition.

How does your decision affect business growth long term? Read customer success stories about what happens a couple of years after go-live. You’ll find that mainstream supply chain suites were built with one focus: to sign lots of contracts. NOT to partner with, commit to, and grow alongside you. 

Opt for flexibility and budget control

Modern WMS solutions give you the highest degree of flexibility and budget control. No surprise fees for adding users, SKUs, or channels. And built-in scaling capabilities – such as a single-codebase cloud architecture – which allow a fast path to new capabilities without a custom project.  

For example, WMS applications that offer 100+ pre-built software integrations allow you to quickly connect systems to ecommerce marketplaces like Shopify, Amazon, etc., along with third-party shipping carriers, EDI networks, and more. They also connect to business applications such as your ERP or CRM, significantly reducing cost and time to get up and running on the functionality you need today. Not 12 months from now. 


These gotchas usually don’t come up in sales talks, but they make all the difference in total cost of ownership, market agility, user adoption, and long-term results. 

ERP or dedicated WMS?

It’s a response we hear all the time: “Do we really need a dedicated WMS or can our ERP handle the job?” Often, companies use their ERP’s inventory fulfillment module — which is really just an accounting system — instead of a dedicated WMS for one reason or another. Just as often, they come back to us regretting that decision. 

Financial systems (ERPs) inform growth, but a WMS directs it. Learn more in this in-depth article:

Other needs to consider

Depth of supply chain management analytics

Deciding on the best WMS also depends on what degree of supply chain management software analytics you require. Some warehouse management systems offer more robust analytics and reporting than others. 

Know what to ask before going into your RFP to clearly understand what you need. Are you just looking for basic KPIs related to what your teams are doing in the warehouse?

  • Performance tracking: picking, receiving, packing, shipping, etc.
  • Hourly number of direct moves, replenishments, cycle counts, etc.
  • Number of transactions accomplished each hour by user, date, activity, location

Or do you need a deeper level of flexibility and extensibility in your supply chain management software analytics, like…

  • Customized/personalized native KPIs and reporting options
  • Ability to make changes to KPI graphical options and manage reporting without source code or a third party
  • Frequent updates with third-party reporting tools
  • Workstation or browser access to view, automate, schedule, and manage reports (with or without printing)
  • Bin-level barcoding and scan validation to understand quality control without taking people off their jobs to physically check every order

What’s the best WMS software for third-party logistics (3PL) firms?

If you are a 3PL that can deliver a consistent, scalable alternative fulfillment experience, the market is wide open. 

WMS software for 3PLs delivers a strong competitive differentiator by solving clients’ labor issues, onboarding new clients quickly, slashing shipping and logistics costs for you AND them, and tapping into a value-rich fulfillment infrastructure.

Example of how WMS software for 3PLs benefits you

Nimbl (formerly ESM Fulfillment) is a great example of how WMS software benefits 3PLs. The firm was struggling with productivity around inventory fulfillment and billing processes for its clients in multiple sales channels. They used to have to pull information from multiple locations and combine it all into a spreadsheet, then put together financial statements based on that. 

Deposco set up their analytics and reporting to show the metrics that are most important to Nimbl’s business, so they could improve team efficiency, sales, and shipment metrics all in one place. The analytics led Nimble to a:

  • 64% increase in order volume in the first 3 months
  • 4-day reduction in their 3PL billing cycle
  • 25% improvement in cycle count and accuracy

Cloud-based SaaS vs. on-premise WMS

Cloud SaaS is excellent for fast scalability and a highly cost-effective, intuitive rollout. With no installation or synchronization required to make updates, companies of any size can manage growth with unlimited flexibility, savings, and control vs. on-premise options.

Differences between on-premise WMS and SaaS

On-premise offers full control and customization but has high upfront costs and complex maintenance. It requires significant technical resources for installation, upgrades, and security, making it suitable for businesses with a large and highly skilled IT team. Most of us don’t have that luxury.

SaaS WMS, on the other hand, is cloud-based with lower upfront costs and easy access from anywhere. It provides automatic updates, scalability, and flexibility, ideal for businesses seeking quick deployment and minimal IT burden. SaaS is perfect for rapidly evolving environments and ensures your systems stay current without frequent or heavy infrastructure investments.

Benefits of a cloud WMS

Cloud-based WMS solutions help you compete and keep growing, not just operate. Learn more about what benefits drive ROI the most

Without the visibility of the cloud, you can’t react or adapt. Research by Bain & Company found that 53% of retailers and consumer goods companies plan to increase their investments in these flexible cloud-based operations – with the worldwide cloud market expected to surpass $354 billion

The best WMS software leverages the benefits of the cloud to elevate your competitive position:

  • One source of the truth: Accurate on-hand inventory everywhere. Excellent for high volumes, expanding warehouse spaces, distributed channels, and unlimited SKUs.
  • Superior inventory control: Automate, organize, and prioritize fulfillment operations to deliver the best customer experience, every time.
  • Collaboration: Fast, secure, reliable information that’s not tethered to physical devices that are sitting in an office or on paper that can get lost.
  • Modern functionality with a lower lifetime cost: The same level of functionality as in-house servers, but without the need for lethargic (and expensive) upgrades, middleware, hardware improvements, or a big IT staff
  • Nimble integrations: Fast to set up and ramp up, ready to integrate with multiple systems including shipping carriers, EDIs, marketplaces, etc., with minimal downtime.
  • Continuous improvement: Baked-in tools to establish optimal routines, measure performance, and identify new ways to provide better service at a lower cost.
  • Labor savings: Fast onboarding and automation to free staff from managing logistics, such as packing and labeling requirements, handling customer complaint calls or billing issues, tracking orders, and more.
  • Revenue growth without overspending: Real-time data generation to support the broad scaling of suppliers, product variety, new channels, and services.

On-premise WMS software ties up cash

On the flip side, an on-premise WMS brings a greater initial investment and higher capital to make operational and financial decisions because you have no good way to see everything going on with inventory inside your warehouse at all times. As a result, the business can’t move beyond reacting to problems and will tap out on growth.

In addition, software costs and entry thresholds are higher due to unanticipated licensing, maintenance, and server expenses. A cloud WMS lets you spread out costs over time, usually on a monthly subscription. A more predictable cost structure permits a significant transfer of funds from op-ex to cap-ex and positive cash flow. 

Case in point, Tyndale

A good example is the work Deposco did with Tyndale, an ecommerce retailer of flame-resistant apparel. After considering 20 different WMS providers, they selected Deposco as the best solution to fit their current and future needs. 

In just 3 months on Deposco’s cloud software, Tyndale saw a 41% increase in order lines picked per hour and a concurrent 99.25% jump in their picking accuracy rate. Read more:
