Stores using a delivery date picker typically report a 15–20% drop in cart abandonment because customers no longer worry about unclear delivery timelines. This article is a map of what DingDoong does. Each feature links to its full setup guide. ## What DingDoong does ### 1. Flexible delivery methods * Offer **local delivery, store pickup, and shipping** — together or individually. * Set **different rules and schedules per method**. * Control your service area with **delivery radius** and **postal/zip code restrictions**. * Apply methods to **specific products** via product availability. See: [How to enable Local delivery](https://help.omegatheme.com/en/article/how-to-enable-local-delivery-1dumpt3/), [How to enable Pickup](https://help.omegatheme.com/en/article/how-to-enable-pickup-b92ckd/), [How to enable shipping](https://help.omegatheme.com/en/article/how-to-enable-shipping-wrwy0d/). ### 2. Flexible scheduling * Configure working days and **blackout dates** (holidays, closed periods). * Set **time slots** per day and **prep/lead times** in hours — enabling same-day or next-day fulfillment. * Allow same-day orders before a **cut-off time** (per-day or for the whole week). * Cap orders with **daily or per-slot limits** to prevent overbooking. * Create **product-specific rules** for special handling. See: [Prep time & cut-off time](https://help.omegatheme.com/en/article/how-to-configure-prep-time-cut-off-time-1y1t4ut/), [How to limit orders](https://help.omegatheme.com/en/article/how-to-limit-orders-xiw9n0/), [Block dates from calendar](https://help.omegatheme.com/en/article/how-to-block-dates-from-calendar-jh27z7/). ### 3. Flexible widget placement * Show the date picker on the **Product page, Cart page / Cart drawer, or both**. * Works with the latest Shopify themes; default placement is the cart for maximum visibility. * **Manual placement** is available for customized themes. See: [Where can you display date picker?](https://help.omegatheme.com/en/article/where-can-you-display-date-picker-lhbf39/) ### 4. Flexible customization * Match the widget to your **brand colors, language, and calendar style**. * Set custom labels and make the date field **mandatory**. * Tag orders with the selected date for easy admin management. * Sync with **Google Calendar** and send **email notifications** for statuses like "Ready for pickup" or "Out for delivery".

The selection follows them to checkout, the Thank you page, and your order admin. ![](https://storage.crisp.chat/users/helpdesk/website/-/8/3/8/3/8383e5404a31c000/image_joa77e.png) ## Before you start * DingDoong is installed from the Shopify App Store. * You can access **Online Store → Themes** to activate the app embed.
