Yes — DingDoong is designed to work with all Shopify themes. Most work out of the box; some custom themes need a small free adjustment from our team. See [Ensuring App Compatibility with Your Theme](https://help.omegatheme.com/en/article/ensuring-app-compatibility-with-your-theme-ci7r7o/). ### Where can the date picker appear? Product page, cart page, cart drawer, or checkout. The cart page is the most popular position. See [Where can you display date picker?](https://help.omegatheme.com/en/article/where-can-you-display-date-picker-lhbf39/) ### Can I test without affecting my live store? Yes — duplicate your theme and test there. See [How to create a test theme](https://help.omegatheme.com/en/article/how-to-create-a-test-theme-1n949f1/) and [How to place an order test](https://help.omegatheme.com/en/article/how-to-place-an-order-test-rjbxys/). ### Does the widget slow down my store? No. The widget script loads asynchronously through Shopify's app embed system and only on pages where it's displayed. ## Delivery methods & scheduling ### Can I offer different schedules for different products? Yes — use [Product availability](https://help.omegatheme.com/en/article/product-availability-1adob22/) to scope each method, and [override rules](https://help.omegatheme.com/en/article/how-to-override-schedule-for-exception-products-ubnc4f/) for exception products. ### Can I limit how many orders I take per day or per time slot? Yes. See [How to limit orders](https://help.omegatheme.com/en/article/how-to-limit-orders-xiw9n0/). When a day or slot reaches its limit, customers can no longer select it. ### Can I block holidays? Yes — add [blackout dates](https://help.omegatheme.com/en/article/how-to-block-dates-from-calendar-jh27z7/) per method. For extra working days outside your normal schedule, use [exception dates](https://help.omegatheme.com/en/article/add-exception-date-bmkxlb/). ### Can I charge extra for specific days or time slots? Yes — see [Add surcharge per day](https://help.omegatheme.com/en/article/add-surcharge-per-day-1kpof9i/) and [Add surcharge per timeslot](https://help.omegatheme.com/en/article/add-surcharge-per-timeslot-oohn4a/). ### Does DingDoong create shipping rates? You can manage rates with DingDoong's [Rates](https://help.omegatheme.com/en/article/rates-ola4f4/) feature, or keep using [Shopify native rates](https://help.omegatheme.com/en/article/how-to-creat-delivery-rates-cm6j4z/). We recommend managing rates in DingDoong for the smoothest checkout. ## Orders & customers ### What happens if a customer checks out without picking a date? Two options: make the date [required before checkout](https://help.omegatheme.com/en/article/how-to-require-date-before-checkout-or-add-to-cart-kj2bc1/), or enable Auto-Recovery so DingDoong automatically emails the customer to pick a date afterwards — see [Auto-Recovery: Automatically recover orders with missing delivery dates](https://help.omegatheme.com/en/article/auto-recovery-automatically-recover-orders-with-missing-delivery-dates-uyiedo/) ### Can customers change their delivery date after ordering? Yes — add the reschedule date picker to your order status page, and customers can pick a new date themselves. Confirmation emails are sent to both the customer and your staff. See [Let customers reschedule their delivery date from the order status page](https://help.omegatheme.com/en/article/let-customers-reschedule-their-delivery-date-from-the-order-status-page-a0zmau/)*(Widget Appearance & Placement)*. ### Where do I see all scheduled orders? In the **Order report** — sync, filter, update statuses (ready for pickup, out for delivery…) and export CSV. See [How to sync Shopify orders for report in DingDoong](https://help.omegatheme.com/en/article/how-to-sync-shopify-orders-for-report-in-dingdoong-o68oem/). ### Does the selected date appear in the order confirmation email? Yes, with a small snippet added to your Shopify notification template. See [How to confirm selected schedule in order confirmation email](https://help.omegatheme.com/en/article/how-to-confirm-selected-schedule-in-order-confirmation-email-phdc64/). ## Languages & display ### Can the date picker display in my language? Yes — translate every text field, with an auto-translate option. See [How to have date picker in another language](https://help.omegatheme.com/en/article/how-to-have-date-picker-in-another-language-tb669e/). ### Can I change the calendar colors and layout? Yes — 5 layouts, custom colors, button shapes, date formats and more. See [Customize your widget appearance](https://help.omegatheme.com/en/article/customize-your-widget-appearance-1oefyzq/) ## Billing & data ### How does billing work? Can I change plans? Plans are billed through Shopify. You can upgrade or downgrade anytime from the in-app **Pricing** page. See [DingDoong plans, billing & how to upgrade or downgrade](https://help.omegatheme.com/en/article/dingdoong-plans-billing-how-to-upgrade-or-downgrade-zlo70r/) *(Plans, Billing & Upgrades)*. ### How long is my order data stored? You control it — set a data retention period and older records are automatically deleted. See [Data privacy](https://help.omegatheme.com/en/article/data-privacy-1bw0pna/) ### What happens to my settings if I uninstall? Uninstalling removes the widget immediately. If you reinstall later, you'll need to reconfigure your settings, so we recommend disabling the app embed instead if the pause is temporary. ## Related articles * [Why is the date picker not showing on my store?](https://help.omegatheme.com/en/article/why-is-the-date-picker-not-showing-on-my-store-oulkh9/)— Step-by-step display troubleshooting *(Troubleshooting & FAQ)* * [Get started with DingDoong set-up!](https://help.omegatheme.com/en/article/get-started-with-dingdoong-set-up-ord7em/)— Full onboarding guide *(Get Started)* ||| Didn't find your question?
