In Hurdlr, income streams related to different companies you own or work with (for example Uber, Lyft, Airbnb, or your personal construction business) are called Businesses. Earnings, expenses and mileage can all be tagged and tracked to a different Business. By doing this you can see your profitability by business at any time.
To add a new business, open the Settings menu (gear icon in top right corner) > Businesses > '+ Add' in the top-right corner.
When you tag new transactions or mileage, you'll be able to select the specific Business that transaction applies to.
