About LastCall: Add to Order

LastCall gives your customers a short window after checkout to add products to the order they just placed — no second checkout, no support tickets. The app edits the original order, keeps your discounts accurate, and sends the customer to Shopify's own balance page to settle just the difference. Added items wait on a fulfillment hold until the balance clears, then ship with the order. You set the time window and switch it on whenever you're ready, from your Shopify admin.

LastCall solves a common problem in a clean and practical way. Customers can quickly add an extra item after checkout, while the merchant keeps everything within the same order. The setup is straightforward, the interface is clear, and the app fits naturally into the existing order workflow. A helpful addition for stores that regularly receive “I forgot to add this” requests.

Very useful app and easy to set up. It gives customers a simple way to add forgotten products to an order they have just placed without creating a separate order or going through another checkout. The experience is smooth, and everything stays connected to the original order. Great solution for improving the post-purchase experience and capturing additional sales.
