Selling a Marketing Agency: Acquire.com or Flippa?

Say an agency bills $4M a year to clients, but $2.6M of that is media spend passed through to ad platforms on the client's behalf, leaving $1.4M in actual agency revenue from management fees and retainers. The founder, who is also the creative director on the firm's three largest accounts, wants to sell within eighteen months.

The agency has fourteen retainer clients and a handful of project-based clients who show up a few times a year. Retention on the retainer base has been strong, three years running without a cancellation, which turns out to matter more to buyers than the founder initially expects, since it's the single clearest signal that clients value the work independent of any one relationship.

In this example, an early buyer evaluating the listing on Acquire.com assumes the full $4M billing figure is agency revenue and offers a multiple based on that number before realizing the mistake during a follow-up call; the founder then has to walk the number back down to the real $1.4M base, which costs credibility even though the correction is accurate. Leading with net revenue from the start would have avoided the awkward reset.

A second buyer, found through Flippa, runs a small portfolio of service businesses and is comfortable working from net revenue and EBITDA from the first conversation, having seen the gross-versus-net distinction before in other services deals. That buyer moves faster to a real number, even though the eventual offer lands in a similar range to what a software-focused buyer might propose once corrected.

The founder ends up running both conversations in parallel for a few weeks, which turns out to be useful beyond just having options. Comparing how differently the two buyers structured their early questions helps the founder spot which parts of the pitch actually needed the net-revenue clarification and which parts were already landing fine.

Because the founder is the creative director on the firm's three largest accounts, both buyers raise the same concern: what happens to those relationships post-close. The founder ends up agreeing to an eighteen-month transition period with a portion of the price held back as an earnout tied to those three accounts renewing, a structure neither platform's default template anticipated but that both buyers arrived at independently, almost word for word.

That convergence is itself useful information: when two buyers sourced through very different channels land on the same concern unprompted, it's rarely worth arguing the point and much more productive to negotiate the structure around it instead of trying to talk either buyer out of the concern.

The deciding factor isn't the platform at all, it's the founder building out a second creative lead in the six months before listing, specifically to reduce dependency on those three accounts. That single change lets the eventual buyer offer more cash at close and a shorter earnout, since the retention risk the whole negotiation kept circling back to was smaller by the time papers were signed.

The founder ultimately went with the buyer sourced through Flippa, not because the offer was dramatically higher, but because that buyer's existing agency portfolio meant a smoother transition for the team staying on. Fee structure mattered less to this decision than most founders assume it will going in.

Start the net-revenue conversation before a buyer forces it, and start reducing founder dependency on top accounts well before you list rather than during negotiations, when a buyer has the most room to demand it. Both fixes take real time, months rather than weeks, so the founders who plan an exit a year or more ahead consistently end up with cleaner terms than those who start the process the same month they decide to sell, no matter which platform eventually sources the buyer.

Takeaways from this example:

• Present net revenue after media pass-through, not gross billings, before any buyer starts talking about multiples.
• Start the net-revenue conversation early rather than letting a buyer discover the gap during a follow-up call.
• Reduce founder dependency on the largest accounts months before listing, for example by building out a second creative lead.
• Expect an earnout or transition period tied to key-account retention if the founder still runs the top accounts.
