How does catalogue demand become a measurable learning loop instead of a weekly guess?

Catalogue work creates customer demand, but the loop is weak when the offer, saleId, POS result, margin, and next buying decision do not stay connected.

• The buyer knows what should sell, but proof arrives late.
• The catalogue creates attention, but attribution is fragile.
• The next decision depends on memory instead of a clean response signal.

Each catalogue offer should carry a saleId from promise to transaction to review. The learning loop gets stronger when demand is measured against real baskets, stock, margin, and store response.

Better demand is not more reporting. It is faster evidence for the next buying and merchandising call.

Start with one catalogue cycle. Join saleId, POS, and margin well enough to answer one question: which offers earned the next repeat, price change, or stock decision?
