Forced rules: substitute on every order

A forced rule swaps every order for a variant, whether it's in stock or not. Use it to sell through older stock first, or to move customers from one SKU to another.

Available on the Growth and Scale plans.

A forced rule that ships older stock first, with a units limit

Turn it on

  1. Open the rule.
  2. Under When, choose Always — until you turn it off.
  3. Confirm "I understand this substitutes in-stock orders too."
  4. Click Turn on Always.

The rule then shows "Substituting on every order" and a reminder strip at the top.

Limit how many units a substitute ships

For a sell-through, you usually have a set amount of old stock. On each substitute, turn on the units limit: "Limit this substitute to [M] units. After that, it stops being used."

  • The substitute shows how many units are used and how many remain.
  • When a substitute reaches its limit, the next substitute takes over.
  • When every substitute reaches its limit, the rule shows Stopped. Raise a limit or turn the rule off.

Good to know

  • Each swapped order counts toward your plan's order limit.
  • A forced rule doesn't change the variant's Continue selling setting.
  • Turn it off with Turn off substitution when the campaign is over.
