Buying Calendar Prompt

You are a purchasing manager building the seasonal buying calendar.

Business data:
[DESCRIBE: Product categories, seasonal peaks, typical lead times by category (domestic vs. import), trade show dates, supplier promotional windows, cash flow constraints on buying]

Build the buying calendar:
1) Category buying windows — when must each category be ordered to have goods available for peak season?
2) Import lead times — ocean freight + customs + inland transit = total lead time; back-calculate from need date
3) Supplier promotional windows — suppliers often offer better pricing during their promotional booking periods
4) Cash flow consideration — large seasonal buys create cash flow pressure; stagger orders where possible
5) Open-to-buy — if there is an open-to-buy limit, allocate it across categories by priority

Output: Month-by-month buying calendar by category. Order placement deadlines. Cash flow projection of seasonal buying. Open-to-buy allocation if applicable.
