Best software to organize shops and assignments?

I have an Excel spreadsheet for posting all of my shops for each year. I use Chrome as a browser and have all companies bookmarked. I use Wave receipts so that I can just take photos of my receipts for tax purposes. I take photos of the odometer on my vehicle each day before starting my shops and at the end of each day. I have found that mileage apps running on my phone take up too much of my battery.
