What tips do you have for efficiently managing and submitting expenses through Emburse Certify Expense?

I try to submit my receipts as soon as I get them. I also label each receipt by naming it the even that I did and date, as Its hard to remember later on when you have so many of the same. Ex. Realtor Lunch - REMAX - 7/24. I Use "Turbo Max" app in my phone to scan the receipts into PDFs and then email them to my work address. I keep a folder in that app. that says which receipts I already submitted. Sounds organized, but it's still hard to keep track of. lol
