double entry accounting would solve this problem by aka "contra" entries most of the time. one thing would be to have a petty cash "virtual account" that pulls money in from your checking account(s), credit cards and pay off groceries from there. that would not be helpful when auditing actual payments because you did actually pay directly from a certain bank and not the pool but this should be simpler for personal use.
