Contract Packing and 3PL Integration: End-to-End Solutions

Modern supply chains face a growing number of challenges and complexities, from scaling and storage to accurate distribution and more. With these challenges increasing, it’s understandable that brands are looking for a unified solution that reduces the number of suppliers they work with. These brands may look to work with a third-party logistics (3PL) provider that offers a fully integrated solution, including contract packing, eCommerce, fulfilment and distribution. Lower costs, higher efficiency, faster speed to market and a better customer experience are just a few of the benefits of working with one trusted provider. In this blog, we’re looking into contract packing and 3PL integration.
Why brands may outsource contract packing
Contract packing, also known as co-packing, involves outsourcing the assembly, packaging and preparation of products to a specialist third-party provider. Services can include kitting, gift packs, promotional packaging, retail-ready displays, subscription boxes, relabelling and product assembly. Once complete, finished goods can then move directly into warehousing and fulfilment.
There are many reasons a brand may outsource its contract packing services, including the following.
Seasonal demands
Many brands ramp up their activities during specific seasons, or if a product suddenly goes viral. Partnering with a reliable contract packing company means you can adapt easily to seasonal demands, even when you may not be able to maintain service quality in-house.
Promotional campaigns
Promotional campaigns often require extensive planning and increased pressure on accuracy. Having a co-packing partner handle these can relieve pressure on your team and ensure your customers benefit from a tried-and-tested method and experience.
Labour flexibility
Some contract packing partners have large in-house teams and, like Granby, also work with trusted bank staff who can support increased demand during peak periods such as Christmas or Black Friday.
Specialist equipment
Brands often struggle with space constraints, which cause issues when additional equipment is needed to fulfil packing processes. Additionally, brands can save money in the long run by working with specialists who already have access to equipment and are responsible for maintaining it. This leads to faster production without having to invest in facilities.
Beyond contract packing: Why integrations matter
Integration can have some significant benefits for brands like yours. Without it, you may face a range of challenges, including the disjointed nature of utilising multiple service providers at once. Without integration, a brand may experience the following.
- Contract packed by one supplier
- Transported to a separate warehouse
- Stored by another logistics provider
- Finally transferred to a different fulfilment centre for despatch
Not only does this process increase storage costs, but it also poses additional challenges, including the following:
- Multiple handling stages: This can increase the risk of damage throughout the supply chain
- Increased shipping costs: Due to items being transported to multiple locations before they reach the customer
- Delays: Adding more steps to the process can lead to increased delays
- Poor stock visibility: It’s harder to track products in multiple locations; this can also cause issues with traceability
- More suppliers to manage: This means it may be harder to build trusted relationships with suppliers, making the whole process feel disjointed
All of these challenges can be appropriately managed with an integrated solution to 3PL and eCommerce fulfilment.

End-to-end solutions
A typical end-to-end logistics solution follows a process similar to the one below.
Step 1: Products received
Products or components arrive directly from the manufacturer. These products are checked against delivery documentation, inspected for damage and verified for important dates, such as best-before or expiry dates, before being booked into stock.
At Granby, we use a comprehensive, in-house-built system which enables you to see exactly where your stock is in our secure warehouse and how the packing process is progressing. We recognise the importance of being transparent in the industry.
Step 2: Packing & assembly
During this stage, your products will be properly assembled and packaged to meet your needs. We can help you with kitting, product collation, promotional packs, gift sets and more. We recently supported a well-known chocolate brand with their Easter promotions, which involved printing names on ribbons and sending these out.
Quality control is embedded into our processes, and we always maintain high standards, ensuring every finished product meets the required specification before despatch. We accurately label all products so they can be shipped to the correct destination.
Step 3: Secure storage
Products can be safely stored in our warehouse, which is covered by a range of security measures, including CCTV, on-site security and a strict entry process.
The warehouse also has BRCGS status and features a secure caged area for high-value goods. We also conduct live, physical stock counts, so you can be sure of how your stock is progressing and we can ensure your project runs smoothly.
Our Warehouse Management System provides full data transparency across all departments, making it much simpler to manage the resources required to complete the job from start to finish. It also enables us to provide detailed KPI reporting, giving you complete visibility into stock levels, order progress and operational performance.
We complete thorough batch control checks and ensure that your items are ready for despatch when required.
How contract packing flows into 3PL fulfilment
When contract packing, warehousing and fulfilment are managed within the same operation, finished goods are immediately available for customer orders. This removes the delays associated with moving stock between separate providers and gives brands a single, connected supply chain with greater visibility and control.
Pick and pack services
As orders are received, warehouse teams can pick and pack products ready for despatch. This efficient process ensures orders are fulfilled quickly and accurately, reducing errors and boosting customer satisfaction.
eCommerce order fulfilment
An integrated approach means that your orders can be processed as soon as they are placed, regardless of the platform used.
Marketplace fulfilment
Many brands sell across multiple online marketplaces, such as Amazon, eBay, TikTok or Etsy. An integrated 3PL provider can manage fulfilment across these channels, helping maintain accurate stock levels.
Retail order fulfilment
Integrated fulfilment services can handle larger retail orders, ensuring retailer compliance and helping brands meet delivery windows.
Courier management
A great 3PL provider manages carrier selection, shipping labels, tracking information and delivery coordination, simplifying the dispatch process for brands. As part of our sustainability efforts, we also work with sustainable couriers who prioritise routes based on environmental factors.
Returns processing
Reverse logistics means that returned products can be received, inspected and processed within the same facility. Depending on the outcome of checks, items may be restocked, repacked, refurbished or disposed of appropriately, helping brands maintain efficient inventory management and deliver a positive customer experience.

Benefits of combining contract packing and 3PL
Faster time to market
Partnering with a trusted contract packing and 3PL partner means your products can move directly from packing into fulfilment and out for delivery. At Granby, we ensure that your products are easy to track and ready on time.
Reduced handling
Fewer handling stages reduce the risk of damage, mis-picks and inventory discrepancies while improving overall operational efficiency. Granby can also support you with reverse logistics and customer services.
Working with us means your products travel within our in-house teams rather than being shipped to different destinations.
Cost savings
Brands using an integrated approach can also benefit from lower logistics costs, as it reduces unnecessary transport while lowering administrative overheads involved. At Granby, we take care of every aspect of packing, 3PL and fulfilment, helping to streamline operations while avoiding unnecessary transport costs.

An integrated logistics partner provides the flexibility to scale without investing in additional facilities or internal resources. At Granby, we are fully equipped to handle seasonal demand peaks, promotions and product launches with confidence.
