OrderBuster (formerly OrderRescue — renamed Oct 2026 at WP.org’s request, see Changelog) targets a gap generic abandoned-cart tools miss: orders that were already placed and are sitting on-hold or pending payment, most commonly stores using manual payment methods (bank transfer, Zelle, crypto, P2P apps) instead of an auto-capturing card processor.
Unlike cart-abandonment plugins, which key off cart state and can misfire on manual-payment orders that are already placed and just awaiting confirmation, OrderBuster watches actual order status — so it never sends a false “you forgot something” email to a customer who already paid and is just waiting on manual confirmation.
What it does:
Runs entirely on your own site’s WP-Cron — no external service, no API key, no account required.
This plugin does not connect to any external API or service to function. The free version includes a small, clearly-labeled sponsor line in reminder emails; clicking it is an ordinary outbound link, not a call made by the plugin itself.
