Ted here from Shopify, thanks for reaching out to us!
Is this in regards to Shopify Payments? If so, then pay periods/payout dates can vary depending on where you are located. If you are based in the United States, then you should receive the funds within 2 business days but more information can be found here if you would like to take a look. Are you experiencing any errors with the payout? If your payments are in a "pending" state after 2 days, then there might be an issue with the bank account you've submitted. Please let me know if this has occurred and I'd be happy to take a closer look.
Congrats on making a sale as well! How are you finding Shopify so far?
Thanks for letting me know! If you click Settings > Paments > Payouts in your admin, could you tell me if the payouts are in a pending state? If so, could you confirm the type of bank account you have listed for Shopify Payments? For example, have you submitted a personal/savings account or a checking account from a physical bank in the US (if so could you please confirm which one)? Or have you entered a US bank account from an online service such as Payoneer?
