Expensify is one of the original expense management solutions on the market. We actually used Expensify for the first few years in business (more recently switching to Divvy).

It started as a simple invoice/receipt scraping tool that you'd forward your receipts into receipts@expensify.com via email, and it would pull out all of the details, learn from past classifications, and sync that over to your accounting software like QBO or Xero.

They have more recently moved into the virtual credit card experience, realizing that if the charge starts with a virtual credit card, all the categorization is way more consistent and seamless (whereas that's where Divvy, Brex, and Ramp all started).
