ABC analysis
ABC analysis sorts your assortment so planning time goes where the money is. Fashion Planner classifies every product option with a two-letter code: the first letter ranks it by re-order sales quantity, the second by how many customers buy it. Thresholds and the definition window are yours to set, the classification runs on your own sales, and the code sits on the same screens where you plan, so ABC inventory classification stops being a quarterly spreadsheet and becomes a live signal on every product.
The challenge
These are the reasons ABC analysis in retail so often stalls, and why brands come looking for something that runs on its own.
A Pareto analysis of inventory built by hand is right the week it is made and stale the week after. New options arrive, sell-through moves, and nobody rebuilds the sheet, so the classes quietly stop matching the range they are supposed to describe.
Ranking on revenue alone calls a product an A even when a single large customer carries it. Sales quantity and how many customers actually buy it are different questions, and a one-dimensional class answers only one of them.
An ABC report in a separate tool is a report nobody opens mid-decision. If product classification does not appear on the screen where the buy is made, it does not change the buy.
An option on sale for six weeks cannot be compared with one that has run a full year, yet a naive ranking does exactly that, pushing genuine A products down and flattering newcomers that have not proven anything.
A tool that fixes A at the top 70% and forgets it does not fit a range of basics, nor one of fast fashion. Without control of the split, the segmentation describes the software's assumptions rather than your assortment.

How Fashion Planner solves it
Fashion Planner is a planning and forecasting platform for textile, interior, beauty, and fashion businesses. Use it on its own, or together with our planning specialists.
Each product option carries two letters. The first ranks it by re-order sales quantity, the second by the number of distinct customers who buy it. One glance tells you both how much it sells and how broadly, which is the difference between a true bestseller and a one-account product.
The classes come from cumulative share of your actual re-order sales over a window you choose, split A, B and C at thresholds you configure. It is a Pareto analysis of inventory that runs continuously instead of once a quarter.
Because quantity and customer breadth are ranked separately, the code moves ABC analysis closer to an ABC XYZ analysis: you can tell steady, broadly-bought products from those propped up by a single buyer, and prioritise accordingly.
An option that has not been on sale for the whole definition window is shown as not classified, rather than ranked on a partial history. The segmentation stays trustworthy, and newness is not mistaken for proven demand.
The class shows on the dashboard, on item planning, in the sales overview and in order entry, with a tooltip that spells out the two letters and the thresholds behind them. SKU prioritization is there at the moment of the decision, not in a report opened afterwards.

In practice
A class is only useful if it changes a decision. The obvious use is forecasting: an A product with broad demand deserves a different model and a closer eye than a C in the tail, and that is where assortment prioritisation pays off. How the forecast follows the demand signal in your own sales is the subject of our article on forecasting in fashion. The class tells you where that attention is worth spending.
The second letter, the customer dimension, is what turns ABC analysis into best-selling product identification. A style that sells in volume to many customers is a different opportunity from one carried by a single account, and spotting the gap is exactly the theme of our piece on finding the bestsellers your customers are not buying. Two dimensions make that difference visible on the product itself.
Classification also feeds inventory policy. An A that many customers reorder should be protected harder than a slow C, which is a question of how much buffer each class carries. How that safety stock is set, by weeks of cover or by service level, is covered in our article on stock projection and safety stock. The class is the input; the buffer is the output.
What changes
The gains come from segmenting the assortment well enough to act on it, not from producing another report.
Every option carries a live ABC class, ranked on quantity and on customers, updated from your own sales
Clear SKU prioritization: A products get the forecasting and buying attention, the C tail gets rules
One classification that sales, buying and management read the same way, on the screens they already use
Inventory segmentation that survives new products, because unproven options are shown as not classified
Buffers and service levels set by class, so cash follows the products that actually earn it
Questions we get
The first letter ranks the product option by its share of re-order sales quantity; the second ranks it by the number of distinct customers who buy it. An AA sells in volume and to many customers; an AC sells in volume but through very few. Reading both is what separates a true bestseller from a single-account product.
Yes. The split between A, B and C and the definition window the ranking is measured over are both configuration, per warehouse. The defaults are a starting point, not a fixed rule, so the segmentation reflects your assortment rather than an assumption baked into the tool.
Classic ABC ranks on value alone. By ranking a second dimension, the number of customers, alongside sales quantity, Fashion Planner gives you a view closer to ABC XYZ analysis without a separate exercise: you can see not just how much a product sells, but how broadly and how dependably.
An option that has not been on sale for the whole definition window is marked not classified rather than ranked on a partial history. That keeps the classes honest and stops newness being mistaken for proven demand.
Yes. Fashion Planner synchronises with your ERP, so the ranking is built from your own sales, stock and orders. Integration is a full service on our side, so it does not become a project for your IT department.
