It depends on who runs it and what you get back. LeanScale's GTM diagnostic is free: a read-only review of your CRM across Growth, Marketing, Revenue and Financial Operations, with a pre-read and readout 48 hours after access. Whatever you pay, expect findings read from your own records, a dollar range on each fix, and the projects that capture it.
We run ours free because it is the fastest way for both sides to see whether there is work worth doing. Judge any diagnostic, free or paid, on three things: whether every number traces to a record you can open, whether value is counted as ARR or just pipeline added up, and whether it ends with named projects in an order you could start on Monday.
Every claim above comes from work LeanScale published. These are the sources.
