The Payments section is where you'll see information on all of the money going to you through your OS. You can also find some information on this in the Payouts History and Setup section within Settings.
At the beginning, this section will look pretty bare, but after a few jobs you'll see all of the payments you've received listed here broken down by date, name of the invoice, how much the invoice was for, the fees that MakerOS takes, the amount paid to you, and the card details.
If you'd like to review a particular order's details, just click on the invoice's name to be brought to the invoice itself within the related project.
That's all you need to know about the Payments section! If you have any questions, please create a support ticket and we'll be happy to help!
