Using a fulfilment house for eCommerce can transform how you run your online shop. These third-party logistics (3PL) providers store, pick, pack, and ship your products so you can focus on growth. For women-led eCommerce businesses in the UK, outsourcing fulfilment is not just a time-saver; it is a practical route to scale without taking on heavy fixed costs.
The State of Women’s Enterprise 2025 report found that more women are starting businesses, though fewer are scaling them, and Prowess’s Women in Business: Key UK Facts page tracks the ongoing contribution of women-led firms. Growth often stalls when founders run out of space, time, or shipping expertise. This guide explains what fulfilment houses do, the UK rules you need to know, and how to decide if outsourcing is right for your business.
Fulfilment houses for eCommerce: what they do
A fulfilment house handles the physical side of selling online. Services typically include warehousing, inventory management, order processing, pick and pack, shipping, returns handling, and tracking updates. Some providers also offer kitting, subscription box assembly, and integration with platforms such as Shopify, Etsy, Amazon, and eBay.
Instead of packing every order yourself, you send stock to the fulfilment centre. When a customer places an order, the fulfilment house picks the item, packs it, labels it, and arranges delivery through carriers such as Royal Mail, DPD, or Evri. Many providers also update your sales channels automatically so stock levels stay accurate across platforms.
Why UK eCommerce sellers use fulfilment houses
The main benefit is capacity. A 3PL provider can process far more orders per day than most small teams, and because they ship at volume, they often secure better courier rates than a solo seller can negotiate. This matters when customer expectations are high; slow or inaccurate delivery directly affects reviews and repeat purchases.
Other practical benefits include:
- Lower fixed costs. You pay for storage and handling rather than leasing warehouse space, hiring staff, or buying packing equipment.
- Geographic reach. A fulfilment house with multiple UK sites, or international hubs, can place stock closer to customers and cut delivery times.
- Seasonal flexibility. You can scale storage and labour up or down around peak periods such as Black Friday and Christmas.
- Reduced overselling risk. Real-time inventory syncing lowers the chance of selling items you no longer have in stock.
- More time for growth. With logistics off your plate, you can focus on marketing, product development, and customer relationships.
HMRC rules: the Fulfilment House Due Diligence Scheme
If you sell goods online in the UK, there is one legal point that is easy to overlook. The Fulfilment House Due Diligence Scheme (FHDDS) requires UK fulfilment businesses to register with HMRC and carry out due diligence on the goods they handle. The scheme is designed to prevent abuse of the tax and customs system, particularly around imports where VAT and duty may be due.
As the seller, you remain responsible for making sure your goods are correctly declared and that VAT and customs duty are paid where applicable. If you use a fulfilment house that is not FHDDS-approved, or if your stock is held incorrectly, you could face delays, penalties, or seizure of goods. Always check that a potential provider is on HMRC’s approved fulfilment business register before you sign a contract.
Tax and compliance considerations for 2026
Outsourcing fulfilment does not remove your tax obligations. Key thresholds and rules for 2026 include:
- VAT registration. You must register for VAT if your taxable turnover exceeds £85,000 in any 12-month period. The threshold is frozen at £85,000 until April 2028, according to HMRC guidance published after the 2024 Autumn Budget.
- Making Tax Digital. From April 2026, self-employed individuals and landlords with qualifying income over £50,000 must follow Making Tax Digital for Income Tax Self Assessment rules. If your eCommerce turnover is above this level, you will need compatible software. Our Making Tax Digital Sole Trader: 2026 Checklist for Women explains the steps.
- Allowable expenses. Fulfilment fees, storage costs, packaging, and courier charges are generally allowable business expenses. See our guide to Allowable Expenses Self Employed UK for a full list.
- Employment costs. If you later bring packing or warehouse staff in-house, remember the National Living Wage for workers aged 21 and over is £12.21 per hour from April 2025, as set by the Low Pay Commission and enforced by HMRC.
How to choose a fulfilment partner
Not every 3PL will suit your business model. Before you commit, ask:
- Are they registered with HMRC under the Fulfilment House Due Diligence Scheme?
- Which sales channels and shopping carts do they integrate with?
- What are the receiving, storage, pick-and-pack, and returns fees?
- Where are their warehouses, and which carriers do they use?
- What are their cut-off times for same-day dispatch?
- How do they handle peak trading periods?
- Can they scale with you if you expand into Europe or beyond?
Request a trial period or a small initial shipment so you can test accuracy, packaging quality, and delivery speed before moving your full inventory.
When to keep fulfilment in-house
Outsourcing is not always the right call. If you sell low volumes, highly customised items, or products that need personal touches such as handwritten notes, you may lose the customer experience that sets you apart. Similarly, if margins are tight and fulfilment fees would swallow your profit, it may be better to keep packing yourself until sales justify the switch.
Practical action steps for women-led eCommerce sellers
- Audit your current order volume, storage costs, and time spent on packing and shipping.
- Check whether your turnover is approaching the £85,000 VAT registration threshold.
- Verify that any fulfilment house you consider is on HMRC’s approved register.
- Compare at least three quotes, including receiving, storage, pick-and-pack, and returns fees.
- Review your accounting software to ensure it is ready for Making Tax Digital if your income exceeds £50,000 from April 2026.
Fulfilment houses for eCommerce can help UK women-led businesses grow without the overhead of running a warehouse. By choosing an HMRC-registered provider and keeping on top of VAT and Making Tax Digital obligations, you can turn logistics from a bottleneck into a competitive advantage.
