Pick your context and we'll surface the most useful resources.
Planning in spreadsheets has a ceiling. Here's how to see it clearly.
Most mid-market apparel brands don't outgrow spreadsheets — they just stop noticing the cost. The OTB errors, the reconciliation time, the carry-over that persists because nobody ran the analysis. These resources help you quantify the real cost and build the case for a better system.

Apparel Planning Maturity Assessment
Most apparel brands do not know where their planning process breaks down until a bad season makes it obvious. This 15-question assessment scores your planning operation across five dimensions: data quality, process consistency, cross-functional alignment, tooling fit, and in-season responsiveness. The output is a maturity profile by dimension — not a generic score — so leadership can prioritise which gaps to close first. The assessment takes under 10 minutes and the output is immediately actionable.

Most apparel margin problems have a planning root cause. These resources help you trace them.
Excess inventory, missed margin targets, buy reviews that take hours instead of minutes — these aren't isolated events. They trace back to disconnected planning workflows, where OTB, assortment, and buy plan live in separate files that no one fully trusts. Understanding the structural causes is the first step to fixing them.
1–3%margin at risk per buying event
4–6 buying events per season · compounds across the full season calendar
// Symptoms in practice
- Post-season review reveals margin was lost, but the root cause isn't traceable to a single decision
- Markdown budget is consumed earlier each season without clear attribution
- Finance and merchandising regularly reconcile to different margin numbers at the same meeting
// What connected planning recovers
OTB, assortment, and buy plan share one data model — margin impact is visible at every decision point, not reconstructed after the season closes.
// FAQ
