Summer inventory planning: why most brands run out of stock in July

Why July is the inventory killer

Most brands run out of stock in July because they planned inventory in April. Summer is when casual shoppers move online for seasonal items like garden furniture, outdoor clothing, camping gear, paddling pools. Categories that sit quiet in winter suddenly spike.

The mistake is treating summer like any other season, planning stock based on average monthly sales. Then July hits, demand doubles, and you are out of stock for three weeks while competitors capture the orders.

How to fix it

If you sell anything seasonal, pull your sales data for June and July from the past two years, work out the peak week, then add 40% to your normal stock order for that week.

A stockout in peak season costs far more than carrying extra inventory. You lose the sale, the ranking boost, and hand the customer to competitors.
