How to I add business mileage to an invoice?

Hello there, Johnny.

Currently, QuickBooks Online (QBO) does not have a built-in feature to add business mileage calculations to an invoice. However, you can add as many vehicles as you need. Also, it's worth noting that QuickBooks Online frequently updates its features and functionality, so it's a great suggestion to our software engineers to include this capability may be added in the future.

If you'd like to send your feedback to QuickBooks Online, it's super easy! Just follow these steps:

1. Select Settings, then Feedback.
2. Enter your comments or product suggestions. 
3. Click Next to submit feedback.
