Best Methods for Tracking and Managing Earnings on Multiple 'Get-Paid-To' Sites

How do you manage your earnings when using multiple 'get-paid-to' sites? Specifically, how do you keep track of your earnings, record them, and monitor pending payments? I'm particularly interested in hearing about any traditional pencil-and-paper methods you may use, or if you have a spreadsheet template or digital app recommendation. I appreciate any options you can provide. Thank you!
