One wrong decision made before the start of the season can turn the entire season into a burden that is difficult to bear. Missing out on a bestseller, stockpiling slow-turning color or sending the wrong collection to the wrong region; It melts the profit not before the sale, but before the production begins. The real issue is not to produce, but to produce the right thing in the right quantity.

Many businesses in the shoe, leather and textile sectors still create their season plans based on the predictions made at the meeting table, the feeling of the field team or by looking at the total turnover of the past year. However, what is needed in today's competition is not brute intuition; It is demand data separated on the basis of model, color, number, region, channel and customer type. This is where ERP-supported planning comes into play.

Top 3 Planning Mistakes Most Common at the Start of a Season

Looking at the Total Number and Missing the Details

The information "We sold 5,000 pairs of this model last season" alone is insufficient. The real critical data; It depends on which color, which number, in which city and in which sales channel. Even if the total quantity is correct, if the distribution is wrong, the stock will still be set up incorrectly.

Treating Every Region as the Same

A product that rotates quickly in Istanbul may not show the same performance in Central Anatolia. As dealer structure, climate, price sensitivity and consumer habits change, the correct collection distribution also changes. The plan, which ignores regional differences, fails at the very beginning of the season.

Copying Last Year and Missing This Year

Last season's numbers are a valuable start, but they are not decisive on their own. The "let's print the same" approach without taking into account price increases, campaign calendar, new customer acquisition, share of e-commerce and product life cycle creates risks.

  • Pre‑purchase requirement for long lead‑time raw materials
