Black Friday is the UK's biggest online shopping event, and the preparation window is shorter than most sellers realise. Getting your inventory, fulfilment, and dispatch setup right before the peak — not during it — is what separates sellers who profit from Black Friday from those who end the weekend exhausted, oversold, and chasing late deliveries.
The single most common Black Friday mistake is running out of stock on best-selling lines mid-event. Review your sales data from the previous 12 months, apply a conservative growth multiplier based on your planned promotions, and book in stock at your warehouse by the end of October at the latest. Stock arriving in mid-November risks not being processed in time for the first wave of pre-Black Friday sales.
If you're using a 3PL, communicate your expected inbound volumes well in advance — warehouses manage their receiving capacity and appreciate early notice of large inbound consignments.
Understand exactly what your 3PL's dispatch cut-off is during peak periods, whether they're running Saturday dispatch, and whether they have contingency plans if order volumes significantly exceed projections. The best 3PLs will have a dedicated peak period operations plan they can share.
Set realistic delivery expectations on your product pages and at checkout during the event. "Order by [date] for delivery before Christmas" messaging starts on Black Friday for many buyers. Proactive order confirmation and dispatch notification emails significantly reduce "where's my order?" contacts and protect your review scores.
Not all Black Friday discounts are equal. A 20% discount on a product with 60% gross margin is very different from 20% on a product with 25% gross margin — especially when you factor in increased packaging, fulfilment, and postage costs per order. Model your margin per unit at your planned discount level before publishing any promotion.
Ensure your Shopify, WooCommerce, or marketplace listings update correctly when you activate promotions. Test your inventory sync between your sales channels and WMS. A misconfigured discount code or a platform integration that drops orders during peak traffic is a preventable disaster.
