Your Sales page tracks all orders you've placed through your Inkthreadable account. This resource will help you keep on top of exactly what you've ordered, when, how much you paid and when it was shipped.
I have three orders placed on my account. There's no value in the Paid and Shipped columns since none of these orders has been paid for, yet. (I totally intend to...)
Clicking the order number for any of these orders will take me to the Order Tracking page for that particular order, where I can check its current status and pay for it if it's awaiting payment.
Crediting your account
Your Sales page is also the place to add credits to your account.
Credits allow for automatic payment of orders as they're received from an integrated store.
Please note: It isn't necessary to credit your account, it just means you'll need to manually pay for each order that's placed through any integration you've set up.
If you don't integrate with an e-commerce platform, credits won't be too useful. You're still welcome to credit your account, and then use these credits to pay for future orders, but it's probably much simpler to pay for your orders as you're placing them.
