Every warehouse needs to define where and how products are moved. This is called warehouse management process flow, and it’s important to have it in place before the order fulfillment process begins. 

There are multiple reasons to be interested in warehouse process flow. Maybe you want to brush up on what is warehouse work, so you can determine who you need to hire. Perhaps your business is developing its first warehouse; in which case, check out what is warehouse. No matter why you’re reading, completing your process flow has an early payoff. 

A well-designed warehouse management process flow saves your business time and money. It defines all the stages in your warehouse operations, so you can focus on getting work done. Keep reading to learn about different types of process flow charts and how to integrate them into your warehouse operations. 

Warehouse Management System Process Flow

A warehouse management system process flow is a visual chart or diagram that shows the main activities of your warehouse. It's a subcomponent of warehouse organization. A process flow illustrates how goods are received, the process they go through, how they are shipped, and any stages in between. 

A process flow can be created through a few methods. You can use graphic design software, the data from your warehouse management system (WMS), or programs like Microsoft Word and Excel.

It’s recommended to spend plenty of time on your process flow, as it can translate to thousands of dollars and dozens of hours saved each year. 

If you use a WMS, creating a process flow is easier. First, export the data you need from your WMS, which provides a detailed account of all the stages your products go through. Examples of data may include product lists, courier reports, and a list of products held longer than 90 days. 

Second, use the data to identify the process flow steps that apply to your warehouse. You can do this in conjunction with an ABC inventory analysis. If you have an unexpectedly high number of C products (goods that spend too much time in the warehouse), your process flow should be improved. 

Your warehouse management system process flow should correspond with your business's needs and how your online marketplace runs (if you use one). It’s advisable to adjust the simplicity or complexity of your chart to streamline warehouse operations. 

Warehouse System Flow Chart

A warehouse system flow chart illustrates the movement of warehouse goods in a visual format. All warehouse flow charts can be broken down into at least three stages: receiving, storage, and shipping. This type of flow chart works best for small warehouses or limited product lines, where products aren’t separated after receiving.

Here is an example of a simple warehouse system flow chart: 


Medium flow charts are much more common and feature more steps. This kind of flow chart is useful for medium to large companies or those with numerous products. 

In addition to the three simple flow chart steps, medium charts include areas for preparatory tasks. This includes multiple storage sections, cold storage vs. room temperature storage, a picking and packing area, and shipping staging or consolidation.

Here is an example of a medium warehouse system flow chart: 


Complex warehouse system flow charts may have 10 stages or more, depending on the products’ needs. These flow charts are common for temperature-controlled products, businesses with high-value inventory, or products with many parts. 

Stages in a complex flow chart may include a reserve warehouse, handling area, production, quality control, and shipping preparation. Some or all of these stages may be present or modified, based on the type of business.

Warehouse Outbound Process Flow

Understanding your warehouse outbound process flow is important for organizational success. It’s a crucial component of satisfying both distribution service providers and customers.

The outbound process flow should include the following steps at a minimum: 

  1. Designate a packing area. The packing location in your warehouse should run like a well-oiled machine. Packing stations should include SKU numbers, barcode scanners, label printers, and packing materials, in addition to the computer for completing orders. Make sure your packing stations are always well-stocked in eCommerce packaging to prevent delays. 
  2. Designate a shipping staging area. This is the location where completed packages are ready to be loaded onto a truck. Drivers can start loading up packages as soon as they arrive because your warehouse is efficiently organized. 
  3. Monitor shipping and delivery notifications. Your warehouse management system (WMS) will provide an interface to see which products have been shipped and which are pending. Some WMSs also provide notifications when customers receive their orders. This eliminates excessive follow-up communication about packages. In the event a package runs into issues, contact your carrier for more information. 
  4. Update your records. Your outbound process flow should include documentation of the products leaving your warehouse and where they went. Whether staff handles this manually or a program does most of the work, you need written proof of all finished work.

Keeping your warehouse outbound process organized in a flow chart is good for maximizing efficiency.

Warehouse Inbound Process Flow

Having a strong warehouse inbound process flow is pivotal to your business’s productivity. Depending on the challenges your warehouse faces, you may need to bring on new staff. Posting an appealing warehouse manager job description can get you candidates quickly. Be sure to include a strong warehouse manager salary, too.

Once you have the right person hired, it’s important to afford the same level of focus to your inbound flow as it is your outbound flow. The inbound process flow of your warehouse should include the following steps: 

  1. Schedule all deliveries. Don’t leave the timing of your deliveries up to chance. This will create a crowded delivery area and delays in unloading pallets. Provide an automated scheduling system for your delivery drivers, or mark down days and times in advance.
  2. Designate an unloading area. It’s easy to overlook the unloading area when making a warehouse inbound process flow. This is space used solely for breaking down cases and carting products to shelves. 
  3. Include inventory management. Simply putting products on shelves isn’t enough; you need an inventory management process built on precision and speed. If your products have special handling or storage requirements, feature this in your process flow, too. Anything individual products need as a part of storage, like warehouse labels, should be part of the inbound flow.
  4. Update your reports. All of your customers’ orders are based on the numbers that your warehouse inventory management software uses. If it turns out a case never got put away or was damaged and never recorded, this directly affects outbound flow. Periodically check that all products are accounted for by running an inventory audit
