Supply chain planning for seasonal demand

Seasonal demand punishes supply chains built for average volume

Many supply chains are designed, whether deliberately or by default, around average monthly volumes. That works fine most of the year, but businesses with genuine seasonal peaks — retail before Christmas, agriculture at harvest, events businesses ahead of summer — need a supply chain that's deliberately built to flex, not just cope.

Start forecasting earlier than feels necessary

The single biggest lever available to any business managing seasonal demand is early, honest forecasting — sharing expected volume increases with transport and warehousing partners well before the peak actually hits, even if the numbers are still estimates. Capacity across transport and warehousing tightens fastest in the weeks immediately before a known peak, so early conversations, even with imperfect numbers, put you ahead of competitors who wait for certainty.

Build flexibility into warehousing and transport separately

Warehousing and transport peaks don't always align perfectly, so it's worth planning each independently rather than assuming a single seasonal surcharge covers both. Consider whether you need temporary additional storage ahead of a demand spike, and separately, whether your transport capacity needs to flex with a lag as stock moves out.

• Forecast volume by week, not just by month, to spot the sharpest peaks
• Confirm warehousing flex space or short-term storage options ahead of the peak
• Pre-book transport capacity for known peak weeks rather than relying on the spot market
• Diversify carriers so a single capacity constraint doesn't stall the whole peak
• Build in contingency lead time for critical deliveries during the peak window

Review after the peak, not just before it

The most valuable planning input for next year's peak is an honest review of what happened this year — where lead times slipped, where costs spiked unexpectedly, and where capacity held up well. Building this review into your process each year turns seasonal planning into a genuine competitive advantage rather than a recurring scramble.

How we support seasonal planning

Because we arrange transport and warehousing through an approved network rather than a fixed capacity pool, we're generally able to flex more readily around seasonal peaks than a single-fleet operator. Our team works with customers well ahead of known peak periods to forecast volumes and pre-arrange capacity — get in touch ahead of your next busy season and we'll help you plan it properly.
