To clarify you’re only a Monzonaught if you work for Monzo
I class finance as anything that’s staying internal to myself so if I’m making a transfer to one of my accounts external to Monzo. Money management so to speak, that money is still in my possession.
If I’m paying any credit card I class it as a bill as you get sent a statement with a total value you owe to that provider.
I use the Finance category for credit card payments, house savings and transfers to other accounts. The Bills categories I use for ‘utilities’ like my phone bill and G Suite subscription.
I currently break down the Monzo categories more granularly in a separate ‘manual entry’ app, so for example:
Bills: TV & Internet
Bills: Gas & Electric
Bills: Water
I am the same - I use the finances category for credit card payments (paying off existing credit card debt). Also for transfers to any external savings accounts.
If I make a purchase on my credit card then pay it off immediately, then I just categorise it as whatever the purchase was, so most likely “shopping”!
I use bills for utilities/insurance/rent etc.
I currently have things like Netflix as “entertainment” although in two minds as to whether I should just lump this in the bill category.
