Just create a "Budget" account and a report that does "Budget" vs "Expenses"

Beancounts budgeting system is fairly poor. It can't handle envelope budgeting, which is the only useful budgeting system I've found so far.

For envelope budgeting, I just make subaccounts of my bank accounts for specific purposes.

It's not great, but what I do is create a fake expense far into the future...
