NOTE: You may have noticed we put ourselves (Red Stag) at the top of this list. That’s not because we’re the best fit for everyone.
In fact, we’re very selective—we only work with less than 5% of businesses who contact us. Our sweet spot is companies shipping big, heavy, bulky products (over 20 pounds) or smaller items with low SKU counts.
However, even if we’re not a perfect fit, you should still reach out. We’ll have an honest conversation about your business needs and challenges.
If we’re the right partner—fantastic. If not, we’ll connect you with a 3PL better suited to your needs. We know the strengths and weaknesses of most fulfillment companies in the industry, and we’re happy to share that knowledge.

How to compare the best ecommerce fulfillment services
The best order fulfillment company for you depends on multiple factors related to your business. Consider your specific needs, like the products you ship, your order volume, and your inventory management processes. Also, look at your need for ecommerce fulfillment services like kitting, labeling, dropshipping, cold storage, custom packaging, and managing returns.
Collectively, the details you uncover about your news will determine the order fulfillment process that’s most likely to deliver the results you’re looking for.
A good place to start is by assessing your current business operations and goals. Ask yourself some questions:
What are your short- and long-term goals?
Are you trying to scale your operations?
Are you hoping to break into a new market?
Are you preparing for increased product demand?
Do you need special services?
NOTE: This list is not exhaustive. It’s just meant to give you an idea of what you need and the types of questions you might ask a top ecommerce fulfillment service company.
Once you’ve answered all of the relevant questions, take a look at how your top choices stack up against each other. Compare various metrics, requirements, and facts, such as:
Parcel weight limits
Order volume minimums
Accuracy rates
Fulfillment center locations
SKU breadth requirements
Parcel weight limits
How large are your products?
Most ecommerce packages weigh less than 10 pounds. So, if you sell products bigger than that, you likely need a fulfillment service provider that knows how to safely store, pick, pack, and ship large products.
Other products may have specific storage and handling requirements, like refrigeration. In these cases, the best fulfillment services will accommodate your needs with the right warehouse space and box sizes.
Order volume minimums
How many packages do you ship each month?
Order minimums are not a judgment of your business. Instead, consider them a good indicator of each 3PL’s strengths. If you ship high volumes of product each month, search for a fulfillment center set up to accommodate your needs. And if you have lower order volume, the best fulfillment services are the ones designed for smaller businesses like yours.
Consider your goals, too. If you’re working toward big, fast growth, the best order fulfillment services are ready to meet your needs today, while also offering the flexibility to scale with you over time. You don’t want to quickly outgrow your order fulfillment service and start the search all over again.
Accuracy rates
How often does the 3PL ship the correct products?
Mistakes happen—but they shouldn’t happen often. Knowing that every mishap costs your business money and potentially harms customer satisfaction, be sure to ask potential fulfillment partners about their error rate.
Some fulfillment service providers allow up to a 4% error rate (yikes!). But, the best order fulfillment companies in this guide boast an accuracy rate of 99% or higher.
Warehouse locations
Top ecommerce warehouses are strategically located for fast shipping
Physical warehouse locations are important because they indicate how quickly your customers will receive their orders. Based on your unique needs, find a third-party logistics company with order fulfillment centers in strategic locations that can get items out to your customers quickly, reliably, and with optimized shipping costs.
Costs associated with warehouse locations
If you ship from multiple fulfillment warehouses, you should expect additional shipping costs to get your inventory to each warehouse location. Plus, you’ll have to closely monitor your inventory management at each warehouse to make sure you don’t run out of stock.
However, the freight shipping costs will potentially be offset by the savings you see from using fulfillment centers that are close to your customers. If you offer free shipping, this can have a big impact on your margins.
SKU breadth requirements
How many unique SKUs do you sell?
SKU breadth is the ratio of how many different items you sell to the number of customer orders you ship each month. Some fulfillment services have a minimum SKU-to-order ratio they allow.
For example, if you sell 100 different SKUs, a 5:1 SKU breadth ratio would require you to ship at least 500 customer orders each month. You don’t need to ship five from each SKU—just 500 orders overall.
Even if an order fulfillment company doesn’t have a SKU breadth requirement, the best ecommerce fulfillment services companies may still want to know your SKU breadth to help understand your business and serve you better.
Other considerations when choosing the best fulfillment company
Products, order volume, and locations are key to your 3PL decision, but there are several other factors to consider. You want outsourced fulfillment from a partner that’s easy to work with and provides the extra services you may need.

Use this fulfillment company questionnaire to help form the questions you ask when interviewing a potential ecommerce fulfillment provider. Be sure to modify the questionnaire to fit your business needs and values. Be specific and thorough.
What questions should you ask an ecom fulfillment company?
Can you handle reverse logistics?
If you need help with returns and refunds, ask an ecom fulfillment company how they handle adding the product back into your inventory, paying shipping costs, and keeping your numbers accurate.
What shipping carriers do your order fulfillment centers use?
Unexpected capacity challenges from shipping carriers can derail your fulfillment, so it’s a good idea to have shipping options beyond the major carriers. A great ecommerce fulfillment company will offer a wide range of companies you can choose from.
Do you offer customizable subscription boxes and other kitting services?
If you offer customized packages or subscription boxes, choose a partner that provides kitting services to assemble your orders—because not every third-party provider will do that.
What sales channels do you support?
Seamless connections between your online store and the 3PL’s fulfillment software are essential for effective order processing. The best fulfillment services in the U.S. and Canada will have ecommerce integrations for platforms like WooCommerce, BigCommerce, Amazon, eBay, and Shopify.
Do you offer real-time insights into inventory tracking?
The best order fulfillment services support your supply chain with frequent cycle counts and accurate inventory management. You can also ask about software that makes it easy for you to manage your orders, shipping, and inventory storage.
How does your customer support work?
Some ecommerce businesses want to set up their ecommerce fulfillment process and then leave the rest to the professionals. Others want to be more involved while getting hands-on account management help from their 3PL. Talk with your prospective partner about the level of support you can expect and how to get it.
How much do your fulfillment services cost?
When you talk to a 3PL about storage fees, fulfillment costs, and shipping rates, make sure to get the full picture. The best fulfillment companies give transparent pricing guidance so you can forecast landed costs.
It can be tempting to choose the least expensive option, but the cheapest option isn’t always the best. Balance cost considerations with the level of service and reliability your customers and your business require.
