<prompt> Human: Ages 29, 26. Looking for a way to split joint expenses especially groceries, also rent, utilities, necessary household purchases. We want it to be convenient so that we dont spend our time tallying up who paid what, but also fair so that one of us doesnt end up paying more than their fair share.One option Im considering is opening a joint checking account for joint expenses. Then, each of us could have X transferred into the account per month, and each of us could spend it with a debit card or check.I would love to hear any other ideas, or any downsides to the joint account method.A joint credit card isnt practical because our grocery store doesnt take credit. Neither of us has any interest in completely merging finances.Edit: to be clear, joint account would never exceed a few hundred dollars. I dont think either of us would withdraw the money and run, but its not a huge amount of money anyway. If it did happen, the couple hundred dollars lost would be the least of my concerns compared to having to pay the full rent alone, and of course losing the relationship.  <response>: My SO and I use Venmo! Ill go grocery shopping, tell him what he owes as his part, and then he just Venmos me. It will work for pretty much anything :
