One season model. Five decisions.

Your data feeds one model of demand. The model drives every planning decision. Each week's results go back into the model, so the next decision starts from what just happened.

  1. 1 · Data

    Your season, in one place

    Sales, stock, products, stores and supplier pack rules from the systems you already run, cleaned and joined by store, style and size.

Every week, what sold and what didn't goes back into the model. The next decision starts from what just happened.

Why one model matters.

Most retailers plan each decision in its own tool or spreadsheet, from its own version of demand. The end of season pays for the gaps between them.

  1. Decisions that agree

    The buy, the size split, the allocation and the markdown all start from the same demand by store and size. They stop contradicting each other.

  2. Lost sales counted once, used everywhere

    Demand hidden by sell-outs is estimated in the model, so every decision plans for what customers came for, not only what they could find.

  3. Each decision teaches the next

    What a style needed to clear informs next season's buy depth. Where a run broke informs next season's size curve.

A week in the loop.

  1. 1

    New sales and stock arrive

    Daily or weekly files, or direct connections, from the systems you already run.

  2. 2

    The model updates

    Demand by store, size and week is re-estimated with what just sold, and what couldn't.

  3. 3

    Decisions are proposed

    Replenishment, transfers, reforecasts and price changes, each with the reasons behind it.

  4. 4

    Planners approve, results flow back

    Approved decisions go to your systems. What they achieve becomes next week's data.

Five decisions, from the first forecast to the last markdown.

  1. 1

    Forecast and plan

    SeasonTail forecasts demand by store, channel and week, and turns it into the sales, margin and inventory budgets your season is bought against.

    Explore forecast and plan
  2. 2

    Assort and buy

    SeasonTail decides which styles each store carries and how many units to buy of each, with the cost of the season's tail already in the numbers.

    Explore assort and buy
  3. 3

    Size and pack

    SeasonTail decides how each buy splits across sizes and stores, and how it ships in packs, so every store keeps a sellable run of sizes until the season ends.

    Explore size and pack
  4. 4

    Allocate and replenish

    SeasonTail sets the first allocation and every weekly replenishment and transfer by store and size, so the run stays whole where customers are buying.

    Explore allocate and replenish
  5. 5

    Price and promote

    SeasonTail decides when, where and how deep to cut price, and which promotions earn their cost, store by store, with the stock each store has left.

    Explore price and promote

Keep your stack. Add one decision.

You don't have to replace a system to start. Pick the decision that costs you most, often size and pack, where the tail is easiest to see. Each one you add reads from the same season model, so it starts with everything the last one learned.

See how it fits together
Works with what you run
Exports from your merchandising, ERP and allocation systems are enough to start. Decisions go back in the formats those systems already take.
Planners stay in charge
Every recommendation shows its reasons. Planners adjust and approve, and nothing leaves until they do.
Your data stays yours
It is used to plan your season, and never shown to another retailer.
