Every acquisition has a moment the documents never capture: the seller’s last day. Twenty years of customer relationships, vendor favors, and how-things-actually-work leaves the building, and most of it was never written down. A 90-day transition period does not fix this by itself, because in the first 90 days you do not yet know which questions to ask. Treat knowledge transfer as a project with deliverables instead. Here is the project.
Deliverable 1: the five-relationship handoff. Before close, name the five relationships that matter most: usually the top two customers, the critical vendor, the banker, and the one employee everything runs through. For each, the seller makes a personal introduction positioning you as the chosen successor, and you leave the meeting with a direct line and a reason to call again within two weeks. A relationship introduced is not a relationship transferred; the second call is where the transfer happens.
Deliverable 2: the shadow schedule. Weeks one and two, you sit in every seat: take orders, ride along on deliveries or service calls, sit with whoever closes the books while they close them, open the mail. This is not symbolic. It is how you find the undocumented steps, and it is how the team learns that you intend to understand the business before you change it.
Deliverable 3: the surprise journal. Every day for 30 days, write down everything that surprised you. The surprises are a literal map of what was never documented. At day 30, the journal becomes your documentation backlog, prioritized by how much damage each undocumented item could do.
Deliverable 4: the retention conversation. The seller is not the only head holding the business. Identify the employee whose departure would hurt most, and within the first month, tell them three things directly: what you see them carrying, that you want them here, and what staying looks like (which may mean money, title, or simply certainty). Key people rarely leave over the sale itself. They leave over silence after it.
Deliverable 5: the question bank. Before the seller’s availability fades, extract the answers you will need in month eight: which customer pays late and why that is fine, which machine fails after which sound, what the busy season actually requires. You will not think of these questions yourself in month two, so use the surprise journal to generate them and book a standing weekly seller call until the well runs dry.
Run these five and the last day is a milestone instead of a cliff. Five Experts members run the transition with the 100-day plan and operators who have lived it. Your first expert intake call is free: a diagnostic, not a sales call.
