Sample data

Built for retailers with 10 to 500 stores

Where a season loses its margin.

Not in one bad decision. In the last weeks, store by store, size by size.

  1. Weeks 1 to 4

    Full price, full run

    XSSMLXL

    Every size is on the shelf. Customers find what they came for.

  2. Weeks 5 to 8

    Core sizes go first

    XSSMLXL

    M and L sell out in the stores that needed more of them. On paper the style still looks in stock.

  3. Weeks 9 to 12

    The tail

    XSSMLXL

    What is left is the sizes nobody asked for in that store. It goes to markdown, and the margin goes with it.

One platform for the whole season.

Five planning decisions on the same data, so each one is made with the end of the season in view.

  1. 1

    Forecast and plan

    Demand and budgets by store, channel and month, built bottom-up from what each store actually sells.

  2. 2

    Assort and buy

    Which styles go to which stores, and how deep to buy, with the season's end in the numbers from day one.

  3. 3

    Size and pack

    A size curve for every store and the supplier packs that deliver it, ready for the purchase order.

  4. 4

    Allocate and replenish

    Weekly moves between stores and the warehouse, before a size runs out where it is selling.

  5. 5

    Price and promote

    Promotions and markdowns by store, timed to clear the tail without giving away margin.

Same buy. Different ending.

A single size curve for the whole chain sends the same mix to every store. SeasonTail gives each store its own curve, so the same units sell through instead of waiting for markdown.

  • Size curves learned per store, not per chain
  • Lost sales from missing sizes counted, not ignored
  • Packs your suppliers can actually build

The run breaks in week 8. 20 units left for markdown.Illustration: one store, one style, twelve weeks, the same 110 units split two ways. Outlined layers are sizes sold out while others remain.

From your data to decisions you can check.

  1. 1

    Connect your data

    Sales, stock, product attributes, stores and supplier pack rules. Files to start, direct connections when you are ready.

  2. 2

    Model every store

    Demand by store, size and week, including the sales you lost when a size was missing.

  3. 3

    Review the plan

    Every recommendation shows why. Planners adjust and approve before anything leaves the building.

  4. 4

    Send it on

    Purchase-order detail, allocations and price changes, in the formats your systems already take.

Built for the people who own the season.

Planning
One season plan that holds from budget to markdown, instead of five spreadsheets that disagree.
Allocation
Store-level size curves and packs, so the first shipment is right and fewer transfers are needed.
Buying and merchandising
Quantities by size you can defend to suppliers, and a clear view of what the range will leave behind.
Finance
Markdown risk you can see before the purchase order, not after the season.

Take the benchmark

About five minutes. Answers are only reported in aggregate.

Questions planners ask.

What data do we need to start?

Two years of weekly sales and stock by store and size, your product attributes and store list. Exports from your existing systems are enough.

Do we have to replace our planning system?

No. SeasonTail works alongside the tools you have and sends its decisions back in the formats they already accept.

Can planners override recommendations?

Always. Every recommendation shows its reasons, and nothing is sent until a planner approves it.

Who is SeasonTail for?

Apparel and footwear retailers with stores, typically from ten to a few hundred locations, selling across seasons.
