PreorderOS ‑ Preorder Manager

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