Client in Baltimore said my agency's reports were just pretty PDFs with no dollar amounts
She told me flat out that our monthly reports showed clicks and impressions but never tied a single metric to her actual revenue, so I switched every client dashboard to lead-to-close numbers and she stayed on another 14 months.
The "pretty PDFs with no dollar amounts" line hits hard because she's right, clicks don't pay her bills. Best thing I ever did was ask clients upfront what number they actually care about (usually revenue or cost per lead) and build the report backward from that. Sounds like you figured that out the hard way too.
