I am the worst at this.. inevitably I end up with not only the infamous shoebox, but also like 6 different e-mail accounts and paypal/stripe accounts to go through trying to find where expenses ended up.

Made worse by the fact that many of my expenses are in USD, so then I have to track it back to the credit card statement to work out exactly how much I was charged.

Would be easier if I just spent a day a month doing this, I'm sure :D
