Hi there, iamluvinlife.

I have some clarification to provide on your question regarding the mileage module.

QuickBooks Online (QBO) currently tracks mileage mainly for reimbursement purposes. Meanwhile, QuickBooks Self-Employed (QBSE) is designed for Independent Contractors, who tracks mileage for estimated tax calculations.

I can see how adding this module in QBO could help your business, I'll be sure to submit feedback to our Product Development Team. They place a lot of value in the ideas provided by users, like yourself, when deciding on how best to improve QuickBooks.

Please know that I'm only a post away if you need additional assistance. I'm always here to provide help and answer any questions that you may have. Wishing you and your business all the best.
