Working notes on finding software spend in an accounting ledger. Each one answers a single question, and says where the answer stops.
Because a card platform's data is its own authorization stream, and a charge that never crosses its card produces no record for it to read. Software paid by ACH transfer, paper check, bill pay, or annual invoice is invisible to it by construction rather than by oversight.
Start from the general ledger rather than the card statement, because the ledger is the only record that contains every payment regardless of how it was made. Pull at least twelve months, group by vendor, and look for charges that repeat on a steady cadence.
Not as a list, no. QuickBooks holds every subscription payment you have made, because it holds every payment, but it has no built-in view that groups vendors into subscriptions and tells you which ones recur. The data is there; the report is not.
