How Online Retailers Should Be Preparing for Christmas

The sun may only just be reappearing and summer promotions rolling out, but for online retailers it’s never too early to start thinking about Christmas.

While sales typically peak towards November and December, festive shopping behaviour starts much earlier. Many consumers begin researching and purchasing gifts as early as September, which means preparation is key to delivering a successful and stress‑free peak season.

From parcel delivery planning and stock management to staffing and marketing, here are the key areas online retailers should focus on to be fully prepared for the Christmas peak.

Choose the Right Delivery Partner

Most online retailers already work with a delivery partner for day‑to‑day national and international parcel fulfilment. However, the Christmas period brings a sharp increase in order volumes, placing extra pressure on delivery networks.

This is the ideal time to review whether your current setup can scale with demand or whether additional capacity is needed. Partnering with a delivery provider that has the infrastructure, flexibility and experience to handle peak volumes can make a significant difference to customer satisfaction.

Choosing a delivery partner early allows time to build a strong working relationship and iron out processes well before peak season begins. At Whistl Parcels, our delivery services are built around a wide, reliable network that supports letters, parcels and larger items — helping online retailers deliver at pace, even during their busiest periods.

Review Last Christmas Performance

One of the most valuable preparation steps is reviewing performance from the previous festive period. Analysing historical sales data highlights which products sold well, when demand peaked and where challenges arose.

Key areas to review include:

• Best‑selling and underperforming products

• Daily and weekly sales spikes

• Website traffic patterns during November and December

• Customer service volumes and delivery queries

This insight helps inform better decisions around stock ordering, promotions and staffing. It’s also worth stress‑testing your website and hosting environment to ensure it can cope with increased traffic and checkout activity during peak periods.

Prepare Your Stock Levels

Few things frustrate customers more than discovering an item is out of stock — especially when time is tight and gifts are needed quickly. Effective stock planning is essential to maximise sales and protect customer loyalty.

To prepare your Christmas stock levels:

• Review best‑selling and most‑viewed products from previous festive periods

• Plan for increased demand by ordering additional stock where possible

• Focus on products that perform well year‑round, as these often make popular gifts

• Monitor market trends and consumer behaviour to predict emerging bestsellers

• Maintain regular communication with suppliers and put contingency plans in place

A proactive approach helps reduce lost sales and avoids last‑minute supply issues.

Plan for Increased Staffing

Higher sales volumes naturally lead to more customer enquiries, order tracking requests and fulfilment activity. To maintain service levels, staffing plans should be reviewed well in advance.

This may include temporary or seasonal staff across:

• Customer service and order support

• Warehouse and fulfilment operations

• Marketing and campaign execution

Ensuring you have the right people in place allows your team to respond quickly to customer needs and keeps the experience positive during a high‑pressure period.

Create a Christmas Marketing Calendar

With festive shoppers active well before December, a clear marketing plan should be in place early. A Christmas marketing calendar helps coordinate campaigns and ensures consistent messaging throughout the peak period and beyond.

Your calendar should cover:

• Key retail moments such as Black Friday, Cyber Monday, Christmas week and January sales

• Email marketing and direct mail campaigns

• Social media activity and paid advertising

• SEO, PPC and retargeting activity

• Promotions informed by previous performance and forecast demand

A structured plan provides time to refine messaging, allocate budget effectively and maximise visibility when competition is at its highest.

Be Ready Before the Rush Starts

Christmas success doesn’t happen by chance. By focusing early on delivery capacity, stock availability, staffing and marketing, online retailers can approach the festive period with confidence.

Starting preparation well ahead of peak season gives your business the flexibility to adapt, scale smoothly and deliver the seamless customer experience shoppers expect at Christmas.
