Lateling is a Shopify app for reviewing orders that may be late or delayed and finding order information to answer customer inquiries. It lists recent orders that have not shipped within a merchant’s chosen time limit or that a carrier reports as delayed, with older orders shown first. Merchants can search for orders by customer email, name, or order number, including guest checkouts, and view fulfillment and payment status, shipping details, tracking links, and delivery estimates when available. To respond to a customer, a merchant selects a reply template that can be filled with details such as the customer’s name, order number, tracking information, and delivery status. The response can be copied as plain text or, with an optional Chrome add-on, inserted into a reply in Gmail or Google Workspace. The add-on displays order information beside the customer’s email; messages are not sent until the merchant sends them. Lateling also provides a customer summary and an option to copy an order summary for use in a chat or support ticket. Lateling runs in the Shopify admin and requires read-only access to customers and orders. It cannot create, edit, refund, or cancel orders. Order and customer data is sent from Shopify to the user’s browser and is not stored on Lateling’s servers. Settings and templates are saved in the merchant’s Shopify store. The optional Gmail add-on connects using a one-time code and supports up to three stores on the Pro plan. Its Gmail integration uses InboxSDK, which may send usage and error reports to that service’s operator, including a hash of the user’s Gmail address.
