The script has run a month and I want to fix it — is that a long process?

No: the change happens in the dashboard in a few clicks, with immediate effect on the line and no service interruption. For deeper changes — a new service, a new area, a new price tier — script coaching stays available, and 15 minutes usually covers it. Every version is archived: if a correction makes the script worse, one click rolls it back. Rule of thumb: fix things early on the first conversations rather than waiting for a big batch.
