Shared expenses and payments

The job here is simple to describe and painful to do by hand: who paid what, what is still owed, and where the receipt is. Watch the transaction fees and whether both parents need to pay.

Worth knowing: These are private apps. None of them is a state child support agency, none of them enforces payment, and a payment record is not a court order. Exports can be useful evidence, but no app can promise a court will accept them.
