Ask HN: What tool do you use for personal bookkeeping?

For keeping track of signups/revenue/expenses/profit on a daily/monthly basis, I use custom widgets on a GeckoBoard status board. They poll a handful of scripts that combine some SQL queries into various products' customer/payment databases, with arrays of fixed expenses and some formulas to estimate variable ones like payment transaction fees for the current month.

For actual bookkeeping, QuickBooks Pro.

I use gnucash. It works fairly well, but the leap to double-entry accounting might be a little strange if you've only used quicken (but a good thing to learn in the long run).

I've been meaning to switch to ledger/hledger, which is command line based, but haven't switched yet.
