Reject specific email addresses or domains before an unwanted order is placed.
Restricted delivery regions
Block countries or locations where the store cannot fulfil or legally deliver orders.
Unapproved B2B buyers
Require a specific customer tag before wholesale or B2B checkout can continue.
Oversized or undersized orders
Set minimum and maximum order values, cart quantities and product-level limits.
Unsupported addresses
Block PO Boxes and addresses containing merchant-defined keywords.
Missing buyer consent
Require age confirmation, terms acceptance or required checkout information.
