Link your CRM
Your existing CRM connected to the conversation, both directions.
What's said in the chat updates the record, and what's in the record shapes the chat. Nobody re-types anything at the end of the day.
You stop running the business off two versions of the truth. The number you quote in a meeting is the real one, and nobody loses Friday afternoon reconciling a spreadsheet against a notebook.
One version of the truth. Not two.
