If your business sells goods, you need a place to store them. When starting out this might be your spare room, garage or a storage locker. As your business grows, most often, this is in a fulfilment centre, distribution centre, or warehouse.

You can purchase land, lease a facility, hire staff, buy equipment, and get customers to buy from you — but it doesn’t stop there. Proper warehouse management is what will determine how successful a business will be.

It won’t matter if you have the most modern state-of-the-art warehouse if it’s not operating efficiently. You will be stuck with poor performing staff, a low-profit margin, incomplete or inaccurate order and inventory visibility, high operating and logistics costs, ineffective leadership, and damaged relationships with customers.

Inbound and outbound logistics are some of the most complex functions of running a business with many literal moving pieces. Learn how warehouse operations affect supply chain management and how to set your business up for success.

What is warehouse management?

Warehouse management refers to the oversight of operations in a warehouse. This includes receiving, tracking, and storing inventory, as well as training staff, managing shipping, workload planning, and monitoring the movement of goods.

What is a warehouse management system?

A warehouse management system (WMS) is software designed to manage and ultimately optimise your operational processes in a warehouse. By implementing a WMS you have full visibility into real-time inventory levels and storage, staff productivity, demand forecasting, and order fulfilment workflows within a warehouse.

Warehouse management systems are important as they eliminate manual processes and guesswork. Streamlining processes that save time and provide a more accurate snapshot of what’s going on inside a facility without needing to conduct continuous warehouse audits.

This information helps warehouse managers identify areas of improvement and track progress to drive optimisations throughout the supply chain, from when inventory arrives to when it’s shipped out to its next destination.

Warehouse management software provides the tools to drive strategic big picture improvements as well as those to monitor the day-to-day. What a management team sees in the warehouse management system will be different from a picker or packer who relies on the system to know what to pick or pack next on the warehouse floor.

Each warehouse management system may have different functionality deployed depending on the business it serves (e.g., what a direct-to-consumer ecommerce seller needs isn’t the same as a large brick and mortar store chain).

5 essential warehouse management processes

Warehouse management is one facet of supply chain management. It affects orders, storage, inventory management, shipping, and distribution. Having an all-in-one solution lets you see what’s happening across different functions of the warehouse in real-time such as inventory being received, orders being packed, shipments being labelled, and any other movement of goods.

1.  Inventory tracking

Inventory tracking is monitoring stock levels so you know which SKUs you have in your warehouse and the exact locations in which you store them, or if they are in transit from a manufacturer or en route to a store.

Inventory management lets you know how much product is ready to be shipped if a customer ordered an item now, as well as when you should order more based on projected volume.

As you grow, you will likely turn inventory over quicker, expand into new locations, and increase your product lines. This makes inventory accuracy and tracking all the more important.

You may even have inventory ring-fenced for specific sales channels. An effective WMS will enable you to manage all these functions and more.

2.  Picking and packing

Picking and packing are two core functions performed in a warehouse. A warehouse management system should generate pick lists for each picker to retrieve items in the most efficient way. This may include zone picking, wave picking, or batch picking.

For each new order, the picker will receive a packing slip of the items ordered and storage locations at the warehouse. The picker will collect the ordered products from their respective locations.

Once an order is picked, it is handed off to a packer, who is responsible for securely placing the items in a box, poly bag or poly mailer, adding in any needed packing materials, and putting a shipping label on it.

3.  Receiving and stowing

Any warehousing operation must be able to receive inventory or freight from trucks at loading docks and then stow them away in a storage location. A warehouse management system will need to be able to scan in each new box received with the inventory quantities it has.

Then, it will be brought to its short-term or long-term inventory storage location, where it will be scanned again. Warehouse management software should provide clear instructions for each user so they know how to receive, unpack, retrieve, pick, pack, and ship inventory.

4.  Shipping

Based on the delivery options and shipping services you offer to customers, shipping carriers like Royal Mail, DPD, Evri, and DHL will pick up orders from the warehouse to ship packages to their next destination.

Once the order ships, your warehouse management system should be able to automatically send ecommerce order tracking information back to your webstore so your customers can track their shipments.

5.  Reporting

A warehouse management system should provide out-of-the-box operational and inventory reports across the warehouse. This may include accuracy in fulfilling orders (total mis-picks, mis-packs, etc.), total orders fulfilled by the hour to measure efficiency of staff, orders shipped on time, and much more.

There are also reports relating to people’s operations including inventory forecasting to understand labour management and staffing needs. With a warehouse management tracking system you can quickly find out which employees have completed safety training, and those who have licenses and certifications to operate certain equipment, and other regulatory requirements you must meet to operate a safe warehouse.

3 ways growing ecommerce stores rely on warehouse management

If you’re experiencing growth and fulfilling orders in an ecommerce warehouse, you need proper warehouse management and oversight in place. This requires experienced experts to manage the warehouse along with the tools and facilities to support not only your volume today but projected growth as well.

1.  Support growth

With growth comes new challenges related to fulfilment logistics. Fast-growing brands understand the impact of warehouse efficiencies, from the number of dock doors that can be used at once and the use of space in the facility, to the number of pickers and packers you have on the floor each hour of the day.

Warehouse management should choose the right technology, shipping carriers, and delivery options to use as well as secure the best warehouse that will meet your future growth without you outgrowing the space immediately. Together, these things help you receive inventory more efficiently, pack boxes quicker, and deliver more orders on time.

2.  Packages are processed and shipped faster

Warehouse management makes operations leaner and improves supply chain efficiency. Stations are designated in each area of the warehouse for each step of the fulfilment process (e.g., separate areas for warehouse picking, packing, labelling, returns, etc.). With each fulfilment member of staff generally focused on one task per shift to maximise their output.

Setting up each functional area for success also means reducing the physical steps needed to get from one place to the next and routing everything in a streamlined way. The faster all of this work is done, the sooner packages are ready to go out the door.

3.  Better storage allocation

Warehouse management helps you store each SKU in a separate dedicated storage location (e.g., in a shelf, bin, or on a pallet or warehouse rack) that makes the most sense for the layout of the warehouse and item in question. Once the inventory is in its place, a warehouse management system helps pinpoint the exact location of any SKU so it can be retrieved quickly.

Accurate warehouse management also helps you keep tabs on real-time inventory levels, so you never run out of stock or run out of space. If you sell products that have expiration dates or are subject to recall, you can also store them by lot number and ship the oldest goods out first.

Warehouse management with a 3PL: 5 advantages

Because warehouse processes are complicated and expensive, many brands choose to outsource the entire fulfilment process to a third-party logistics (3PL) company. Unlike an on-demand warehousing company that finds warehouses with excess space, 3PLs run their own fulfilment centres and should have standardised warehouse management across all of them.

Here are some of the advantages of working with a professional logistics company to store inventory and ship orders.

1.  Logistical efficiencies

3PLs work with thousands of companies — including seasonal brands, high growth brands, and everyone in between — so they have a lot of data and can do everything from analysing delivery efficiency to forecasting demand and inventory. Continuously aggregating and learning from data helps optimise each warehouse for greater efficiency as well as provide reduced shipping costs and transit times for your customers, all of which help you grow.

2.  Multiple warehouses and larger geographic footprint

When you run your own warehouse, you are only shipping from that one location. Partnering with a 3PL means you can store inventory in several of their fulfilment centres to keep inventory closer to more customers. If you ship internationally, it’s a must that you have warehouses located close to your international shoppers. Large physical distances and additional cross-border taxes are just two reasons it may make sense to work with a fulfilment partner that has multiple locations across the world.

For example, ShipBob has 35+ locations globally, including in the UK, Europe, USA, Canada, and Australia. By cutting delivery distances, ShipBob sellers can reach their customers quicker and cheaper by storing their product closer to shoppers. In addition, by cutting out the issue of cross-border taxes (for example between the UK and European Union), sellers see tangible improvements in both website conversion and customer retention rates.

“We want everyone to get their Ombraz in a few days or less with no duties at delivery. Our goal is to remove the barriers to purchase. Now, a customer can get their package without spending an extra 25 euros on duties and taxes after purchasing a pair of sunglasses. We found that sending inventory to Europe involved less paperwork and was faster than expected. The process of getting inventory sent to ShipBob’s European fulfilment centre was very streamlined. ShipBob has helped us extensively throughout the process and we look forward to accelerating our growth outside of North America.”

Nikolai Paloni, Co-Founder of Ombraz Sunglasses

3.  Huge time savings

Ecommerce order fulfilment services from a 3PL eliminate the most time-consuming logistics tasks (inventory storage, picking, packing, shipping, order tracking, replenishing supplies, returns, kitting, etc.) and the stress of managing a warehouse. While they take care of these tasks for you, you can monitor their performance and use the data they provide to grow and make better business decisions.

“Fulfilment is one of the areas that we were super keen to outsource to a partner who’s been doing it for a while and knows how it’s done. We can trust ShipBob to support and handle fulfilment for us, so that we can focus on the strategic side of our business, helping us grow and develop much faster.”

Adelina Zotta, Co-Founder of NutriPaw

4.  Better uses of warehouse space

If you’re on the verge of outgrowing your warehouse space, working with a 3PL can make your life a lot easier. Even once you’ve outsourced fulfilment to a 3PL, you can either repurpose your old warehouse space to focus on a different aspect of your business (e.g., growing your B2B ecommerce or wholesale fulfilment channels in-house), or let the lease end.

A 3PL can help you pay for only the space you need — even if that’s by the bin, shelf, pallet, or any combination of those for your products. That way, you’ll never have to worry about outgrowing (or never growing into) the space you’re paying for.

“Fulfilment isn’t our forte, and we don’t want it to be. We want to focus on adding products and growing our online community. ShipBob is an amazing partner to our strengths. As a family-owned business, it was important to know that our fulfillment business would continue to be treated the same way as we treat it ourselves — and we definitely got that with ShipBob.”

Sara Moradi & Amir Nizancevic, Co-Founders of iVYVERDURE

5.  Real-time insights

Just because you’re not working inside the 3PL’s warehouse doesn’t mean you won’t know what’s happening. Through their technology, you should be able to see your inventory flow, including when inventory is being received, stowed or put away, picked, packed, shipped, and any other movement.

With ShipBob’s proprietary warehouse management software, you can search orders by tracking number, destination country, the number of items it contains, filter by sales channel, fulfilment centre location, as well as get full transparency into performance such as fulfilment speed, orders fulfilled on time, accurately, claim-free, and much more.

“The technology ShipBob offers is the real differentiator, and the selling point is the visibility and transparency of the dashboard.”

Brett Miller, CEO, BRIK

3 things to look for in your next warehouse management system

If you are set on managing your own warehouse, make sure you do your due diligence and get a warehouse management system that works for your business’s unique needs.

1.  Software that connects to your store(s)

Integrations with your online stores will make everything go smoothly, from sending individual tracking info back to customers to monitoring sales trends to be able to support demand. By feeding in your sales channels, the warehouse management system will generate pick lists that optimise each picker’s workflow based on the logic that matches your warehouse design and items ordered.

In addition to picking similar orders that take inventory in the same area or rows, it should make sure orders that were placed first or request express shipping are prioritised, so you can keep promises you make to customers (e.g., “Any orders placed before noon local time are guaranteed to ship the same day”).

Pro-tip: use a warehouse management system together with a project management platform to boost overall integration and execution of your retail supply chain operations.

2.  Software that’s compatible with your warehouse equipment

Based on how your warehouse is set up and operates, you’ll want to make sure any warehouse management system you use is compatible with inventory scanners, terminals, labels and printers, scales, handheld or wearable devices, and other physical equipment or hardware you use. If not, be sure to factor in any additional purchases you’ll have to make.

3.  Demonstrated ROI

In addition to hearing how other businesses have had success with a specific warehouse management system, including those similar in size and industry, look for examples of time and money savings demonstrated through the software such as:

  • X time saved per hour
  • X percent improvement in accuracy or reduction in errors
  • X dollars saved or recovered
  • X increase in order processing speed or throughput

If you can’t understand how the warehouse management system can positively impact warehouse operations, then you can’t justify the investment.
