A good acquisition isn’t something the buyer does to the seller, or the seller does for the buyer. It’s something both parties build together. When each side understands what’s expected of them — and holds up their end — the deal closes cleanly, clients stay, and everyone comes out ahead. When one side drops the ball, everyone pays for it.

The Seller’s Job: Make It Easy to Take Over
The seller’s primary job is to make the business transferable. That sounds obvious, but most agencies aren’t built to hand off — they’re built around the owner. Before the deal closes, the seller should be able to hand a buyer a clear Book of Business (every client, what they pay, what they get), a set of documented processes, and accurate financials broken down by recurring vs. project revenue.
If those things don’t exist yet, the time to build them is before the deal conversation — not during it. Buyers who walk into due diligence and find everything organized gain confidence. Buyers who find chaos start discounting.
Beyond the paperwork, the seller’s most important role happens after the deal closes: the personal handoff. A seller who calls each client, sends a warm announcement email, and shows up on intro calls is protecting their own earn-out as much as they’re helping the buyer. In a revenue share deal, client retention directly determines how much the seller gets paid. The transition isn’t a courtesy — it’s in the seller’s financial interest to do it well.
The Buyer’s Job: Earn the Trust That’s Being Transferred
The buyer isn’t just acquiring a book of business — they’re inheriting years of trust the seller built with each client. That trust doesn’t transfer automatically. It transfers through how the buyer shows up in those first weeks.
The buyer’s job before close is to do real due diligence: verify the MRR, understand the tech stack, assess client concentration, and make sure the services being acquired are ones they can actually deliver. Agreeing to take on a book of business you can’t support is a disservice to the seller, the clients, and yourself.
After close, the buyer’s job shifts to relationship-building. That means scheduling intro calls with every client, responding quickly to the seller’s announcement email, setting up billing smoothly, and over-communicating through what is — from the client’s perspective — an unexpected change. Closing rate with existing clients who’ve been properly transitioned can be 90–100%. That number drops fast when the buyer goes dark.
The buyer also has a responsibility to the seller’s legacy. The seller chose you — often over higher offers — because they trusted you’d take care of the clients they spent years serving. That’s not something to take lightly. How you treat those clients in the first 90 days determines whether you deserved that trust.
What Both Sides Are Responsible For Together
The handoff process works best when both parties plan it together — not when the buyer hands the seller a script and disappears. Before close, buyer and seller should align on:
- The exact sequence of client outreach (seller calls first, then emails, then buyer follows up)
- The tone and content of the announcement email — the buyer typically drafts it, the seller customizes it in their own voice
- Which clients need extra care (long-tenured, high-value, or relationship-sensitive accounts)
- The timeline for billing migration and account transfers
Transparency matters throughout. Clients don’t need to know every detail of the deal — but they do need to feel informed, not surprised. The goal is for every client to hear about the transition directly from the seller before they hear it from anyone else. That sequence — seller first, buyer second, billing change third — is what keeps retention high.
When both sides play their roles well, the deal becomes something worth pointing to. I’ve had sellers reach out months after close to say their clients are thriving, they’re making more from the earn-out than they expected, and they feel good about how it ended. That outcome doesn’t happen by accident — it’s the result of both sides showing up and doing the work.
Whether you’re approaching this as a buyer or a seller, the fundamentals are the same: be organized, be transparent, and be a good partner through the transition. If you want to talk through what that looks like in practice, reach out to CyberOptik.
