In 2015 I worked with Intuit on an illustration update for Quickbooks. All of the pieces, esp. the icons, are a collaborative result with their in-house design team- Sherry Ding, Scott Ng, Shawna Kirby, and Hetal Soni. Since then they’ve adopted the style on the Quickbooks Online and mobile app. Many illustrations/icons were created, here are some of the examples.
