Many of you have asked for the ability to create your own categories. It's actually our most requested feature since we launched QuickBooks Self-Employed.
In order to make sure we provide the best possible solution, we're actively researching how we could approach this so that it solves for the primary concerns raised by you while also preserving the integrity of the categories as your country defines them (ie. Schedule C in the United States) to ensure your Estimated Taxes aren't negatively impacted.
We'll keep you in the loop on our progress and will share any details as soon as we have them.
