Finley from Shopify here. Thanks for your question!
Have you been able to confirm which payment gateway processed your customer's order? The way you receive your payouts will differ depending on this.
1) Shopify Payments
If you use the Shopify Payments gateway, you can check on the status of your payouts by going to your Shopify Admin > Settings > Payments > Shopify payments > View payouts.
You'll be able to click on any of your existing payouts to check on the particulars of each.
These payouts will be deposited into the bank account details you entered in whilst setting up Shopify Payments.
PayPal is a default payment gateway that will be connected once you create a Shopify account. The email you used to sign up for your Shopify account will be the email used for the PayPal Express Checkout account unless you've updated this.
If your customers paid with PayPal, PayPal would've sent an email to the connected email address where you can complete your account set up and claim your payout. You can check what this email is by going to your Shopify Admin > Settings > Payments > Paypal section.
Something to note is to be able to manually capture payments and refund orders, you'll also want to finish setting up PayPal on your store.
If you have any questions about your PayPal account or claiming your funds, you can contact PayPal here.
3) Third-party payment providers
If you've set up a Third-party payment provider, you'll want to double-check with the payment provider's support team as to how the funds will be deposited and in what time frame, since they're external to Shopify.
Check how your customer paid for their order
To confirm which payment gateway was used when the customers paid for their orders, you can go to your Orders tab, click on the order number, and scroll down to the order’s timeline like so:
By clicking the little triangle next to the last four digits of the customer's credit card number, you'll see a further breakdown of the transaction's details as well.
