Order-triggering products
SKUs that pull the rest of the basket
Triggers vs heroes
Hero SKUs get the marketing budget. Trigger SKUs get the repeat rhythm — often lower glamour, higher operational importance because they drive frequency.
Stock triggers like stock heroes
A stockout on a trigger SKU silences the whole basket. Prioritise alerts, shelf position, and supplier backup on these lines — not only on campaign SKUs.
Connect to customer scoring
Customers who only buy triggers on promotion behave differently from those who repeat at full margin. Score them separately before you set free-delivery thresholds.
