The subscription box boom shows no sign of slowing down, with experts estimating the market to have 18.5% compound annual growth between 2024 and 2032. This strength of the market means there are exciting opportunities for new and expanding subscription businesses, but choosing the right subscription fulfilment strategy is essential for continued success (and your sanity!).
Fulfilment Options for Subscription Businesses
eCommerce businesses tend to handle subscription fulfilment in one of two ways:
In-house fulfilment means your team manages the entire process, from storing inventory and assembling subscription boxes to shipping them out and handling returns. This gives you complete control over every aspect of the fulfilment process, but it needs significant time, space, and resources.
Third-party logistics (3PL) involves outsourcing your fulfilment operations to specialists like Delta Fulfilment, who manage warehousing, picking, packing, and shipping on your behalf. A good 3PL partner becomes an extension of your business, handling the logistics while you focus on product curation, marketing, and growth.
Many subscription businesses start with in-house fulfilment because it makes sense when volumes are low. You can personally make sure each box is perfect, add handwritten notes, and control every aspect of the customer experience. However, as subscriber numbers increase, the sheer amount of work involved often becomes unsustainable.
In-House Fulfilment vs Third-Party Logistics
You might be at a crossroads right now, carefully weighing up your fulfilment options.
Perhaps you’re launching an exciting new subscription business and wondering how to handle logistics from day one.
Maybe you’re an established eCommerce store looking to diversify with subscriptions, but unsure how it fits into your current operations.
Or you could be running a growing subscription service from your spare room, watching orders pile up and realising that packaging boxes until midnight isn’t sustainable anymore.
Wherever you are in your journey, deciding whether to keep fulfilment in-house or partner with experts is a big decision for your business.
Quick Guide: In-House Order Fulfilment Vs Using a 3PL
| Factor | In-House Fulfilment | Using a 3PL |
| Control | Complete control over packaging and presentation | Less control over the fulfilment process, but professional standards and branding options available |
| Cost | Lower costs for small volumes, higher as you grow | Higher initial costs, but better rates for shipping and materials |
| Space | Requires warehouse space that grows with your business | No need for your own warehouse space |
| Staffing | Need to hire, train and manage fulfilment staff | Expert staff are included in the service |
| Scalability | Limited by your space and resources | Easily scales with your business growth |
| Time | Significant time spent on fulfilment operations | Frees up your time to focus on growth, product development and marketing |
| Technology | Need to invest in inventory and order management systems | Access to advanced fulfilment technology and tracking |
| Shipping Rates | Standard retail shipping rates | Discounted shipping rates through courier partnerships |
| International Reach | Complex to manage international shipping | Established international shipping networks and expertise |
Cost & Scalability
Choosing a cost-effective order fulfilment strategy is the first concern for many businesses. In-house fulfilment might be cheaper if you’re just starting a subscription business, but as you grow, there’s a tipping point where the costs of warehouse space, staff, packaging materials, and shipping start to add up quickly. Plus, there are hidden costs like the time you spend managing fulfilment instead of growing your business.
Scalability is also key. If you plan to grow your business, you’ll need a fulfilment service that grows with you. In-house, this means constantly finding more space, hiring more staff, and buying more equipment. With a fulfilment partner, scaling up is as simple as sending more inventory to the warehouse, and they handle the rest, whether you’re shipping 100 boxes or 10,000.
Around seasonal spikes and important eCommerce shopping days, a good 3PL can quickly adjust to higher volumes without you needing to hire temporary staff or scramble for extra storage space. This flexibility is especially valuable if you sell special holiday boxes or run limited-time promotions.
Shipping Speed
Today’s customers expect fast, affordable subscription box fulfilment and delivery, and meeting these expectations can make or break your retention rates.
If you’re doing fulfilment in-house, shipping can be tricky to get right. If you only offer standard shipping, it will keep your costs down, but customers may be disappointed that your boxes are slow to arrive. But if you use express shipping, it will eat into your profit margins, or if you pass it on to your customers, it could make your subscription less competitively priced.
If you partner with an experienced 3PL, you’ll benefit from their established relationships with multiple courier services. These partnerships usually mean you can access significantly lower shipping rates than you could achieve on your own. Usually, you’ll also be able to pick between different carriers so you can get the best balance of cost and speed for your business needs. This is particularly helpful if you need European fulfilment or global fulfilment.
If your brand stands out by being eco-friendly, having green shipping is a basic expectation. At a small scale, this can be expensive to achieve, but working with a 3PL can unlock affordable green opportunities. For example, we provide sustainable fulfilment options, including eco-friendly packaging and optimised delivery routes that reduce the carbon footprint of each subscription box you send.
Technology, Tracking & Customer Service
People will expect their boxes to arrive at roughly the same time each month, creating a rhythm and anticipation that’s part of the subscription experience. When fulfilment issues cause delays or missed deliveries, this rhythm breaks and damages customer trust. You can avoid this by using stock management software to manage your inventory for subscription products, and order tracking systems to keep customers updated on when to expect their delivery.
You also use order processing and tracking data to trigger emails to your customers that build a sense of community, boost customer engagement and help improve retention. For example, if you run an arts and crafts subscription box, you might send an email to build excitement before it arrives and share hints and tips on how to use the items inside. A week or two later, you could contact them again to encourage them to share their creations on their social channels and tag your brand.
You can set these systems up yourself, but it will often take a lot of time, money and technical know-how. A good third-party fulfilment provider will have these tools ready to go. Many integrate easily with popular eCommerce systems like Shopify, Etsy, and TikTok Shop, meaning your orders will flow automatically from your online store to the fulfilment centre, with no need for you to send data manually.
Steps to Choose the Right Fulfilment Strategy
Finding the perfect fulfilment approach for your subscription business isn’t a one-size-fits-all decision. Here’s how to evaluate what will work best for your specific needs:
Know Your Volume & Frequency
Start by getting clear on your numbers. How many subscription boxes are you shipping each month? Is this number growing steadily or experiencing seasonal fluctuations?
For smaller volumes (under 100 boxes monthly), in-house fulfilment might still be manageable and cost-effective. As you cross that threshold, the benefits of a 3pl partner like Delta Fulfilment become more compelling, as it will save you time, and the economies of scale will start working in your favour.
Consider your shipping frequency, too. Do you send all subscriptions on the same date each month, or do customers have different billing cycles? A single mass shipment might be easier to handle in-house, while rolling shipments throughout the month benefit from the consistent processes of a fulfilment partner.
Evaluate Your Customisation Needs
When your customers receive their box, opening it should be an enjoyable experience. Your packaging needs to be both practical (protecting the contents) and part of the unboxing experience (creating excitement).
To decide which fulfilment method is best for your business, you need to decide how important this level of customisation is to your brand experience. It can help to be objective and realistic about which elements of customisation truly add value for your customers. Take a look at your feedback or even survey your customers to work out what matters versus what might be nice but not essential. Sometimes, professionally packed boxes with consistent branding actually create a more premium impression than variable hand-packed options.
For businesses where orders are going out in small batches, it’s more manageable to do in-house order fulfilment and add in personalised touches like handwritten notes or promo pieces to add extra delight. But for businesses with a wide range of products and high order rates, it’s better to use a 3PL that can accommodate manual customisation. Some 3PLs provide “kitting” services where they can assemble custom box combinations according to your specifications. Delta Fulfilment specialises in subscription box assembly, with options for adding personalised elements while keeping the process efficient.
Consider Your Tech Integration Ability
Your fulfilment process needs to work smoothly with your existing systems. Think about how orders flow from your website to your fulfilment operation, how inventory is tracked, and how shipping updates are communicated to customers.
If you’re using popular eCommerce platforms like WooCommerce or Amazon, look for a fulfilment partner with established integrations for these systems. Knowing the scope of the platforms they integrate with is also helpful, as you might want to expand across several in future too.
Do a Cost Analysis
Finally, run the numbers. Compare the true costs of in-house fulfilment against outsourcing options. Be sure to include all expenses:
For in-house fulfilment:
- Warehouse space rental
- Staff wages and training
- Packaging materials
- Shipping costs
- Technology investments
- Your own time spent managing the process
For 3PL partners:
- Storage fees
- Per-order fulfilment costs
- Shipping rates
- Special handling charges
- Integration or setup fees
Remember that the cheapest option isn’t always the way forward for growth. Factor in the benefits of freed-up time, reduced stress, professional expertise, and the ability to scale smoothly when comparing your options.
