The Draft Orders for POS app is simple to use. There are no settings in the Shopify Admin area of your site, so once you are done installing it and confirming your subscription, you can head over to any Shopify POS device.
From there, you will need to invoke the app from the cart. You can do so by clicking the there dots in the top right corner of the cart.
On phones and smaller tablets, you may need to add a product to the cart to access the cart.
Once you have opened the app, you will be shown a list of your draft orders (up to 250). You can easily search by number, email, first and last name. Once you select a draft order, the contents of the draft will show. You can then add it to the cart or delete the order.
