Treat the first sixty days as recovery work and extend the milestones by about four weeks. Week one becomes reconstruction, building a relationship inventory from invoice history, quote records, and accessible email archives with internal help. Introduction calls become discovery calls, since no warm handoff is possible. On the first customer conversation, acknowledge plainly that the account has been unattended, ask what they need, and fix one thing quickly. Prevent the situation going forward with a one-page handoff document per significant account.
