PreorderOS ‑ Preorder Manager

PreorderOS - Preorder Manager allows ecommerce merchants to run controlled pre-orders with clear dates and alerts. It enables setting pre-order limits, dispatch dates, waitlists, and customer updates for selected product variants. Merchants can create pre-orders with quantity caps, start and end dates, estimated dispatch dates, and selling rules. The app also offers customization options for buttons, badges, product and cart messages, and shows remaining quantity while pausing sales when the cap is reached. Additionally, it allows collecting waitlist signups when a pre-order sells out and sending customer events to Klaviyo and merchant alerts via Slack or Microsoft Teams.
