Shopify
Orders as customers place them, and payouts as they land.
Orders arrive as they happen rather than on a schedule. An order placed at eleven at night is in your numbers at eleven at night.
Payouts are matched back to the orders that produced them, which is the step that normally gets skipped. Shopify pays you a batch; that batch is dozens of orders minus fees minus refunds. Matching it is how you learn what you actually earned.

How to connect it
Enter your store address, the one ending in myshopify.com.
Shopify lists what is being read before you agree.
If you run more than one store, each connects to its own business.
What arrives, and when
Orders, products, and payouts, with orders arriving as they are placed.

They come through with the order they belong to, so revenue is net of them rather than overstated.
