Ted here from Shopify, thanks for reaching out to us!
Have you a store with Shopify? Are you hoping to create a test order or a real order to see if everything is set up correctly? If so, who is your payment provider? If you let me know a bit more about the current store's set up and how you would like to proceed, I'm more than happy to take a closer look into this with you.
All the best,
Sure thing! How are you marketing the store so far? Have you launched the store as of yet? Could you link me the URL for your store and I'll take a look at the current set up you have?
Thanks a mill,
