FOR MARKETING
Promote the stock you will actually have.
Marketing plans to one calendar and the buy runs on another, so the campaign lands on stock that sold out in week two or never arrived. Merchmix puts both on the same weeks and the same hierarchy, so spend follows the stock rather than guessing at it.
WHAT YOU GET
Four things marketing gets out of it.
Know you are inside budget in the week you plan it.
Spend is planned by week against the approved budget line with the variance row directly underneath, so an overspend shows up in the week it is planned rather than in the month end wrap.
Never launch into a category that cannot support it.
Every campaign week shows what the buy has planned into it, so a launch cannot be booked against a range that has no cover.
Know what a discount costs before you approve it.
Open a promotion and it resolves to the styles it will actually apply to, with the margin each one lands at and the markdown cost split out.
Stop arguing about which version is live.
Plans are held by financial year with the status on the front of the card. Approved plans freeze, and exploring an alternative forks a draft rather than editing the signed off plan.
The marketing calendar reads the same weeks, hierarchy and budget as the buy, so the promotion in the plan is the promotion the merchandiser is trading against, and the cover you are spending into is the cover the planner committed.
THE CYCLE
Plan the year, cost the promotion, watch it land.
Marketing runs through three stages, and each one reads the numbers the last one committed. Nothing is exported and keyed between them.
Plan the promotion against the category, not against a date.
The promo calendar runs the merchandise hierarchy down the side, so a promotion is attached to a department, category and subcategory rather than a date in a marketing calendar. The whole year sits on one timeline by week, so overlapping promotions are visible before the calendar is committed rather than discovered in trade.

Know what the discount costs before you commit to it.
Open a promotion and it resolves to the styles it will actually apply to. Each carries what it did on promotion last year, what it lifted, what it is predicted to lift this time and the margin it lands at afterwards. Markdown cost is split into gross discount, retailer funded and vendor contribution, so what the promotion costs the business is known before approval rather than reconciled after the season.

Watch the spend against the plan you approved.
Actuals arrive through connectors on the channels themselves rather than being keyed, and land on the same weekly grid as the plan. Spend, orders, revenue and variance read against the approved number, so the conversation in week six is about what to do rather than whose figures are right.
Each stage commits into the next, so the calendar you signed off is the calendar the actuals are read against.
