Ask HN: Business owners: which software to keep track of expenses/receipts?

Struggling with which direction to go here. Currently I have a slew of paper receipts I've been meticulously keeping ordered in a special paper notebook, along with detailed dates and descriptions for the line items. I need to upzone my tech stack. Looking at the 'receipt scanner / software' reviews on Amazon, everything is spat on my the reviewers. I'm wondering if I shouldn't just move to taking pictures of the receipts with my phone so I can throw them out (I'm in the U.S. and I'm pretty sure paper isn't a requirement), but then I need a clever system to keep track of them. What do you do that works for you?
