Catch bad addresses before the courier does.
Catch incomplete or low-quality shipping addresses at checkout (missing house number, too short) before they turn into failed deliveries and re-shipping fees. HPOS-ready, no jQuery.
Built by a store owner, not a plugin company — every CartMend plugin runs live on my own store, stickitsibiu.ro. — Manu
Built for one specific job. No bloat. Tested on WP 6.5+ and WooCommerce 8+. Block and classic checkout supported.
No subscriptions. No renewal traps.
Works on both Block Checkout (modern) and Classic Checkout. No JS hacks.
