Inside the checklist

Most of peak is decided in October. This is what to check before then.

Most of peak is decided in October. This is what to check before then.

This is one of the checklists we run with the chains we work with. Most of it can be done by hand, with exports you already have and a spreadsheet. Every check has the question to ask, how to get the answer yourself, the number that means act rather than note, and what to do about it.

Phase 0 · Data readiness

Proving you can pull the export, and agreeing how sell-through and weeks of cover are calculated before anyone argues about them.

01 · Demand forecasting

Finding your real peak week, and the categories where 45% of the season lands in three weeks.

02 · Inventory and replenishment

The date each top seller runs out, the stock sitting in the wrong store, and the phantom inventory nobody is counting.

03 · Promotions and markdown

Which promotions created real lift, which ones run negative margin, and setting markdown triggers in October instead of debating them in December.

04 to 06 · Stores, online, and the peak itself

Store clustering, holiday staffing against the hourly curve, ad spend against days of cover, and closing the season in five days.
