How to Choose the Best Order Fulfillment Software

by EasyPost

Let's face it. The right order fulfillment software has become one of the most critical weapons in your business arsenal. Over the past decade, consumers have set an extraordinarily high bar for retailers. In the wake of Amazon Prime, more than 90% of U. S.  online shoppers now expect free two- to three-day shipping from every company. Studies show that when delivery times are too long, almost 50% will simply choose another retailer.  As a result, speed and accuracy when shipping orders have become an absolutely essential element of a successful retail business. This means that efficient order fulfillment has never held a more important role. Fortunately, technology has come to the rescue in the form of order fulfillment software. 

What is order fulfillment software? 

Order fulfillment software is technology used to manage the entire fulfillment cycle from the moment a customer orders an item until it arrives on their doorstep. Modern order fulfillment software includes a few key features:

  • Manages, orders, and updates inventory in real time 
  • Creates and assigns pick lists for your warehouse team 
  • Automates and coordinates the packing process for your team
  • Shares real-time tracking of orders during every stage

What are the benefits of using order fulfillment software?

With order fulfillment solutions, companies benefit from reduced errors in order entry, automated invoices, increased order visibility, managed returns and more. Reasons small businesses use order fulfillment software include:

  • Eliminates need to own or rent a warehouse
  • No need to hire additional employees to handle your order fulfillment
  • Ability to scale business as quickly as desired
  • Saves businesses time and money

What to look for in an order fulfillment software

Hundreds of different order fulfillment software options are available out on the market. What should you be looking for when selecting the right one for your unique business? The best order fulfillment software will have the following characteristics:

  • Easy integration with your other important technologies. From your WMS to your ERP and everything in between, all of your tech stack should communicate easily with one another. 
  • Automation, automation, automation!! This should nearly go without saying, but order fulfillment software that doesn’t leverage automation isn’t worth your time. Automation will help speed up processes and reduce errors significantly and is one of the main reasons companies use order fulfillment software. 
  • Intuitive navigation. It’s a fact of life that warehouse staff come and go far too often. Your order fulfillment software should be easy for new team members to understand. In addition, make sure the software you’re considering makes it easy to search for, edit, and view orders and/or invoices. 
  • The ability to manage inventory. Having just the right amount of inventory is the goal of every company. You want enough that you can meet demand but not so much that you are sitting with a warehouse full of unwanted goods. The right order fulfillment software will include inventory alerts to help you keep your finger on the pulse of your inventory at all times. 
  • Easy returns processing. Returns are a normal part of the shipping process. Be sure that the order fulfillment software you select makes returns as easy as possible. 
  • Access to data and reports. The ability to run reports and see metrics is critical in order for you to be flexible and make adjustments whenever necessary. These reports should be accessible from both a computer and mobile device and include a centralized dashboard so you can quickly get all the information you need.
