Tourism seasons move HORECA demand before they move the news
Hotel and restaurant purchasing in the coastal provinces and the northern cities changes months ahead of the arrivals themselves, because kitchens plan covers and menus in advance. A supplier who starts the conversation when occupancy is already high is negotiating with a purchasing officer who has committed for the period. The same is true in reverse: the quiet months are when a kitchen is willing to trial an ingredient, which makes them the right time to sample rather than the right time to stop calling.
Modern trade promotional windows are booked long before they run
Retail promotions and gondola periods are allocated well ahead, so a supplier arriving with a promotional proposal in the month it is meant to run is arriving for the following cycle. Recording those windows on the retailer account, and scheduling the preparation backwards from them, is the difference between planning a promotion and reacting to somebody else. It also makes the internal argument easier, because production and marketing can see the same dates the buyer is working to.
Festival and gifting demand sits on top of everything else
Gifting and festival periods create short, intense demand for particular pack formats, and the orders come from customers who may not buy the rest of the year. Treating those as their own seasonal accounts, with last year volumes on the record, means the approach happens early enough to secure production capacity rather than late enough to be turning business away because the line is committed.
