3PL inventory management helps retailers reduce costs and improve supply chain efficiency. When implemented correctly, 3PLs handle complex logistics so your business can replenish and ship inventory more efficiently.
But sometimes retailers face challenges when outsourcing to a 3PL. Perhaps you can’t see your partner's stock levels. Maybe you’re selling out-of-stock products or even restocking your worst-performing SKUs.
All those issues beg the question: Which 3PL inventory management system is right for your business? This post will highlight the key benefits, challenges, top software available, and best practices for improving 3PL relationships.
What is 3PL inventory management?
Third-party or 3PL inventory management is the practice of outsourcing the storage, tracking, and distribution of goods to external companies.
Instead of managing its own warehouse and inventory, a retail business hires a specialized 3PL company to do it for it. This can save time and money and let the business focus on creating, marketing, and selling products.
3PL inventory management software is a specialized tool for managing the flow of goods within a business. Most software can track products, manage orders, and ensure accurate and timely delivery.
The goal of 3PL inventory management is to streamline inventory replenishment, lower costs, and scale up operations.

Challenges of 3PL inventory management
No matter if you’re setting up a retail shop or running a booming online store, maintaining an efficient 3PL inventory management system has its challenges.
Inaccurate stock levels
One big challenge of 3PL inventory management is keeping track of exactly how much stock is available. When orders are fulfilled by a 3PL, you don’t always see what’s selling well, which products to buy in larger quantities, and what products are underperforming and need to go on sale.
Sometimes, the numbers can be wrong due to mistakes in counting or updating the system. Merchants may think they have more or less of a product than they actually do, causing issues with orders.
For example, your site may list a product as in stock when you don’t have any available. Shoppers then purchase the product before realizing it isn’t available, causing issues with customer satisfaction.
Lack of visibility
Sometimes, retailers don't have a clear view of their own inventory. This means they can't always see where their products are or how they're moving through the entire supply chain. This lack of visibility can make it hard to make informed decisions and respond quickly to changes in demand.
Increased costs of outsourcing
While outsourcing inventory management to a 3PL can save money in some areas, it may also increase costs. Zeroing in on the third-party logistics sector, the 2023 3PL Warehouse Benchmark Report shows that managing costs ranked as the top business challenge, and nearly half (48%) of respondents will need to overcome it in 2024.
These costs can come from the fees charged by the 3PL provider, the need for advanced tech, and rising storage costs. In 2023, asking rents for US distribution and warehouse space reached a record-high $9.72 per square foot in 2023, up 20.6% year over year. Warehouse worker wages rose by 7.4% in 2023 too.
Benefits of 3PL inventory management software
To run a profitable and scalable retail business, you need to have products available when customers are ready to buy them. Inventory management software can enhance your retail business in several ways:
Real-time visibility
With 3PL inventory management software, companies get real-time access to their inventory data––you can see exactly what's happening with your products at any moment.
Real-time visibility helps you make better stocking decisions, respond quickly to changes, and keep customers informed about their orders.
Accurate inventory tracking
Rather than guessing your inventory levels, you’ll know exactly how much stock you have available for sale. Solid inventory management software updates inventory levels when a product is purchased or returned.
Accurate tracking ensures stock levels are always up-to-date, reducing the chances of errors like overstocking or stockouts.
Faster order fulfillment
Customer expect their orders to arrive fast. Some 62% only want to wait up to three days for a package. Inventory management software can help you meet these increasing customer demands.
For instance, software can automatically generate purchase orders when stock levels fall below a certain threshold, so popular items are always in stock and ready to be shipped. Plus, most software integrates with order management systems, enabling seamless order processing across different sales channels.
Some software can even provide insights into the best ways to organize inventory in the warehouse, making it easier and faster for staff to pick items for orders.
Scalability
As your retail business grows, managing inventory from a spreadsheet isn’t always feasible. Manual inventory management leaves too much margin for human error and is too simplistic for growing businesses.
Good inventory management software lets you scale up or down your operations. When you have a clear idea of your inventory needs, adjusting your storage and logistics capacity is easier.

5 best practices for 3PL inventory management
Regardless of the 3PL inventory management system you choose, these best practices will improve your collaboration with 3PLs.
Ensure returns functionality
Returns are a part of selling goods online. Failing to offer returns may lower customer satisfaction and leave money on the table. Yalu Xu, a marketing specialist at Momo Lifestyle, explains that your chosen 3PL needs to offer returns so you’re not unnecessarily losing money.
“Retailers can recover significant value when returned products are sent back in unused condition. In these cases, you can put returns back into your stock and sell them again,” she says. “Any 3PL inventory management software should have this service available so you don’t lose money unnecessarily from customer changing their mind.”
Communication
Frequent communication with your 3PL provider keeps everyone in the loop and ensures details don’t get lost in the mix. Xu recommends creating a WhatsApp group with your 3PL provider.
"Having a WhatsApp group is key for small emergencies that arise from time to time, such as when another service provider or warehouse does not ship your order on time. In these situations, it's important to be able to count on your 3PL provider to ship out the order for you before any shipment deadlines."
Set clear expectations
Setting clear expectations early on helps both parties understand what’s realistic. Defining roles, requirements, and processes at the outset helps set up the relationship for long-term success.
Shawn Stack, the founder and CEO of Hallmark Timmins, explains you should put your expectations in writing before beginning a partnership.
“At the start of the partnership, have an in-depth discussion about each party's responsibilities, performance metrics, reporting needs, and protocols for resolving issues. Put service-level agreements in writing to create accountability on both sides,” he says.
“For example, I once partnered with a 3PL to manage our shipping and logistics operations. By outlining upfront the required order accuracy rate, expected transit times, and protocols for reporting and resolving discrepancies, we created transparency and avoided misunderstandings down the road.”
Understand the shipping framework and costs
Define your shipping methods and costs before committing to 3PL inventory management, Will you cover shipping costs? Or will you use the 3PL’s carrier shipping rates?
Shipping rates vary depending on the location of the buyer in relation to the 3PL warehouse, so it’s important to understand the costs different purchases incur in advance.
Yalu Xu of Moma Lifestyle recommends comparing shipping costs for several test locations, “Make a comparison of different shipping speeds (standard, expedited, and 1-2 days) for each product based on the shipping price to send to four locations. For example, in the US, these could be New York, Florida, Texas, and California. Doing so will help you understand the real costs of shipping in advance to ensure you choose the best option.”
Conduct regular audits
Regular audits are like inventory check-ups. They ensure that the number of products you think you have matches the number of products you actually have.
Here’s how to do them:
- Schedule regular audits: Plan to do audits often, like once a month or once a quarter, so you can catch any issues early.
- Use different methods: Sometimes, count everything (a full audit). Other times, just count a few items (a cycle count).
- Check for accuracy: Compare what you counted to what your 3PL system says. If there's a difference, work with your 3PL to figure out why.
- Update records: If you find mistakes, update your records to make sure they're right.
- Identify patterns: The same repetitive mistakes indicate a bigger problem to fix.
