Why do customers fall through the cracks during handoff to customer success?

Customers fall through the cracks at handoff because the moment feels like an ending to you and it is a beginning for them, and sloppy transfers drop everything you both worked for. The deal closing is not the finish line. For the customer, it is the start of whether the promise was real. A customer who has to re-explain their situation to a stranger feels abandoned, and that feeling erodes the trust you earned to make the sale. What prevents it is not more effort but a reliable transfer of the essentials: what they were promised, what they expect, and what matters most to them. Before your next handoff, write down the three things CS absolutely must know to keep this customer whole, and walk them through it directly, not over the wall. A clean handoff is a promise kept. Make it a habit, not an afterthought.
