How to compare e-commerce fulfillment services for your business
Choosing shipping fulfillment services can be a tough decision because of the numerous available options. To make it easier, we’ve compiled the key factors to consider when weighing different options. They include:
Parcel size and weight limitations
Fulfillment services often have limits on the weight and dimensions of a product they can ship. You should confirm these limits with your desired fulfillment provider to avoid issues in the long run.
Are your products lightweight or bulky?
Weight limits usually start from 50 lbs (23 kg) and upwards. Most goods fall under this limit, but if you sell heavier items, you should confirm if your fulfillment provider can handle them. Some providers handle heavier shipments with extra charges, while others may decline any item above the specified limit.
Dimension also plays a role, with maximum lengths usually between 120 cm and 150 cm. If you ship bulky products, such as fitness equipment, that surpass these dimensions, you can compare different fulfillment options to see which one readily handles them.
Minimum order volume requirements
E-commerce fulfillment services often have minimum order volume requirements, e.g., at least 100 orders monthly. They do this to avoid losing money on small orders, as shipping can be expensive for smaller items.
The good thing is that you can find a viable fulfillment provider regardless of your order volume. While some providers have minimum order volumes, many others willingly process small order volumes for up-and-coming online stores.
What’s your monthly order volume?
Order minimums aren’t a judgment of your business but rather a way for fulfillment services to work with the order volume their infrastructure is built for. If you ship a high order volume each month, you can work with suitable fulfillment providers that handle large orders efficiently.
If you run a small online store with low order volume, you can also find suitable fulfillment services to handle the logistics. Many e-commerce fulfillment solutions are very scalable, so you can keep working with them even as your order volume grows.
Accuracy and reliability rates
Mistakes happen when packing and shipping inventory, but they should be minimal. Every mistake costs your business money, so you need a fulfillment management service that makes as few mistakes as possible.
How accurate is the fulfillment process?
You can ask potential fulfillment partners about their error rates, and some already publish this information on their website. 99% accuracy and a minor 1% error rate are ideal when choosing online fulfillment services.
Warehouse location and distribution
Your fulfillment provider’s warehouse network is the main factor that determines its shipping speed. Third-party fulfillment companies can ship goods fast when they operate warehouses close to your customer base.
How do shipping costs vary by location?
The farther a warehouse is from a customer, the more expensive it is to ship items to the customer. Hence, you need a third-party fulfillment service with warehouses close to your customer base, preferably in the same country, to avoid extra expenses associated with international shipping.
If you have a global customer base, you can choose third-party logistics services that operate warehouses across the countries where your customers are located. The more distributed the warehouse network, the better for your online store.
Product variety and SKU handling
A Stock Keeping Unit (SKU) is a unique code that you use to sort inventory. It’s a distinct identifier that makes it easy to manage your product inventory. SKUs can get complex because of product varieties, including size, color, and material. For example, your store may sell a clothing item listed in five different sizes and ten colors. You’ll need SKUs to sort them out.
How diverse is your product catalog?
If you sell products with a large variety, ensure that your fulfillment provider is capable of handling this variety. Some e-commerce fulfillment solutions can handle higher SKU counts and diverse product catalogs than others.
Key factors to consider when choosing a fulfillment partner
Essential questions to ask a fulfillment provider?
A fulfillment provider can make or break your e-commerce business. Hence, you should ask comprehensive questions before selecting one, including:
Can they manage returns and reverse logistics?
Returns are inevitable when running an online store. At some point, a customer may return an item because it’s not the right size or because they don’t like what they received. Thus, you need a fulfillment provider that can process returns without hassle for the customer.
Which shipping carriers do they work with?
Third-party fulfillment providers can operate their carrier network or work with external couriers to handle product shipping. Confirm which option a fulfillment provider uses before selecting them. Ideally, they should work with multiple shipping carriers with robust infrastructure close to your customer base. Working with multiple carriers ensures redundancy, where a mishap from a single carrier won’t slow down your whole business.
Do they support subscription services?
Your e-commerce company might offer product subscriptions, where customers receive goods monthly or at other specified intervals. This model is most common in consumables like pet food, shaving kits, and groceries.
If you run an e-commerce subscription service, you need a fulfillment service that specifically supports it. You also need one that offers customized packaging services, as personalization is often paired with e-commerce subscriptions.
What sales channels are integrated into their systems?
The best fulfillment solutions have integrations with popular e-commerce platforms like Shopify and WooCommerce. These integrations enable all customer orders to be automatically sent to the fulfillment provider instead of doing it manually, which takes valuable time.
Do they offer real-time tracking and inventory insights?
An ideal fulfillment solution should let you track orders in real-time. You should have access to a dashboard displaying which items have been delivered, are in transit, or are awaiting processing.
How responsive is their customer support?
When things go wrong, you need a support team ready to resolve issues quickly. Customer service is crucial because it reflects heavily on your interactions with buyers. If your fulfillment provider offers excellent service, you can, in turn, quickly resolve issues that your customers face, improving satisfaction and long-term loyalty.
How much do their fulfillment services cost?
Pricing is crucial, as whatever your fulfillment provider charges will be passed on to your customers. Confirm your fulfillment company’s shipping and packaging costs and ensure you’re comfortable with them. Shipping costs vary depending on size and distance, but fulfillment providers have price guides that tell you what to expect. Confirm the pricing information before making your final choice.

How to evaluate the best fulfillment partner for your business needs
Business model
Your online store’s business model is the first factor affecting the potential fulfillment services you can work with. The type and size of your product determine which partners you can choose in the first place.
For example, if you sell everyday products like jewelry, clothing, accessories, and toys, you can work with most fulfillment providers because these items don’t weigh much and are easy to ship. However, if you sell bulky products like furniture, you’ll be limited to fulfillment services that specialize in handling large packages.
Scalability
Your e-commerce business will likely not remain the same size forever. As you gain more customers and your shipping needs grow, you need a fulfillment service that can easily absorb this new load. Your logistics provider should be able to handle increasing order volumes without sacrificing delivery speed and reliability. Ask questions beforehand and confirm that your fulfillment partner can handle increasing volumes if needed.
Transitioning to a third-party solution
You may run in-house fulfillment operations and seek to transition towards third-party fulfillment. This situation is typical for smaller e-commerce businesses with a growing customer base, which makes it challenging to continue shipping goods on your own. The good news is that you can easily transition to third-party fulfillment whenever needed.
When transitioning from in-house to third-party logistics, the same factors we’ve discussed earlier apply. You need a fulfillment provider that handles your shipment sizes and order volumes efficiently. The provider should be scalable, offer excellent customer service, and have competitive shipping prices.
After selecting a third-party fulfillment provider, you can integrate their app with your e-commerce platform. Then, you’ll hand over your goods, and the fulfillment provider will take care of further shipments to customers.
Future trends in fulfillment solutions
E-commerce fulfillment solutions are increasingly shifting towards more automation, sustainability, and rapid delivery.
Automation has long been a staple of the third-party fulfillment industry, but the recent artificial intelligence (AI) boom has opened many more automation opportunities. AI systems now help warehouses run more efficiently by forecasting demand ahead of time, analyzing inventory levels to provide insights, and reducing labor costs, leading to reduced prices for e-commerce businesses.
Climate change awareness is at an all-time high, which has increased the demand for sustainable packaging. Customers are now increasingly seeking online stores that use biodegradable packaging materials. Hence, you need a fulfillment provider that’s keeping up with sustainability trends to ship goods with a minimal carbon footprint.
Depending on their location, some customers increasingly expect delivery in as little as one or two days. Amazon, Walmart, and other big e-commerce companies kickstarted this rapid delivery, and smaller online stores have had no choice but to adapt. You need a fulfillment provider with a distributed network that can ship goods as quickly as possible to your customers.
