You can construct a fully customizable 1-click order form for the Cash on Delivery purchases using Releasit QuickForm upsell app, which enables you to swiftly collect orders without having to go through the convoluted Shopify Checkout processes.
The forms will be deactivated by default when Releasit is installed on your store, allowing you to alter them without having an impact on your online shop. After completing your form's customization, use the app's settings to turn it on.
Your customers will have the ability to place orders easily with only one click after you activate the form on the store! They will be routed to your store's thank you page once they made their order.
