Most businesses do not need a bigger funnel before they know what happened to the enquiries they already paid for.
You send a small sample of the lead trail. Inbox rows, CRM exports, quote lists, missed calls, or anonymised screenshots are enough for the first pass. I do not need passwords to start.
I sort the rows by practical recovery value. Source, date, job type, likely value, last touch, response gap, and whether a human follow up still makes sense.
You get back a short report with the leads worth chasing first, the reason each one matters, and the safest next action. Some rows will be marked as not worth chasing. That is part of the work.
The audit is deliberately boring. It is there to find missed work, not to make your business dependent on another tool.
