A sell rate you can trust.

Sell rate counts only the days a size was actually in stock, so a stockout never makes a bestseller look slow.

  • Leaves out launch week, the days after a PO lands and days with no stock
  • Switches to the recent rate when a style starts slowing, and says so
  • Holds a size at zero when its returns run 25% or higher

Run-out and order-by dates per size.

Each size gets a run-out date and an order-by date that allows for your supplier’s lead time, so you see the problem while there is still time to fix it.

  • Out now, Order overdue, Due this week or Covered at a glance
  • Suggested quantities that count stock on hand, stock on order and the waitlist
  • Draft purchase orders from the sizes you select, one per supplier

Markdowns, planned and reversible.

Plan a markdown with tiers and a margin guardrail, schedule it, and restore prices when the sale ends.

  • Prices written per market and pushed to Shopify
  • Scheduled start and end, with prior prices restored at the end
  • A trapped-cash view of stock that has stopped selling, ready to add to a plan

Watch the market around you.

Follow competitor Shopify stores and see their price changes and launches next to your own catalogue.

  • Price changes and new launches from the stores you follow
  • Back in Stock waitlists feed demand and size curves

Questions

How is the sell rate calculated?+

Units sold per in-stock day over a trailing 28-day window, which you can change. Days without stock, launch week and the days after a PO lands are left out.

Can I create a purchase order from the forecast?+

Yes. Select the sizes to reorder and KNKTD OS drafts one purchase order per supplier with the quantities filled in. Nothing is sent until you issue it.

Do markdowns update Shopify?+

Yes. A markdown writes prices per market and pushes them to Shopify, and ending the promotion restores the prices that were there before.

What about brand-new styles?+

A style gets its own sell rate 14 days after launch (you can change that). Until then it shows as too early to call rather than guessing.

Is demand planning included in every plan?+

Yes. All four plans include every module, from $100 to $500 a month. Plans differ only by how many team members you can add, and every plan starts with a 14-day free trial.
