Likely accidental orders and promo abuse

Two orders with exactly the same products and quantities, placed within the window you set (10 minutes by default), are labeled likely accidental. OrderMerge suggests cancelling and refunding the newer one in Shopify (More actions, Cancel order) instead of shipping both. It never cancels orders itself.

This label is on every plan.

Pick your limit-one discount codes and products in Settings. When an order uses one of them at the same address or phone as an earlier order in the last 90 days, under a different email, the group gets a Promo abuse badge and the ordermerge:promo-abuse tag, and is held when holds are on.
