How to build enterprise value in a service business before selling
Sold a 28 employee electrical contracting business in late 2024 after about eighteen months of structured exit prep, and the prep period leading up to listing was where the multiple was made, not the listing itself. Writing up the framework I worked through since exit prep specifics for service businesses dont get talked about with much honesty most places.
Buyers price transferability in service businesses, will the business keep producing cash without the owner in it. Everything that proves yes increases value, everything that proves no decreases it.
Owner dependency: The largest factor. If you're still in every client relationship, every sales conversation, every operational decision, buyers assume revenue drops when you leave because no evidence shows otherwise. Documenting that managers run accounts, that key customers have multiple touchpoints, that operations function without you in the room, raises the multiple.
Recurring revenue structure: Month to month verbal agreements with great clients feel safe because the relationships are strong, on paper they look like revenue that could vanish any month. Converting clients to annual contracts with auto renewal before listing shifted my multiple by roughly 0.6x.
Documentation: The lever buyers use to assess transferability risk. If these only live in your head, buyers price in the loss of that institutional knowledge. Real written sops change the conversation.
Customer concentration: Kills deals. Buyers walk from clean businesses when one customer is 30% or more of revenue. Spent twelve months diversifying before listing and dropped my largest customer from 38% to 19%.
Team retention: The metric buyers drill into late in due diligence. They want to know who stays after you leave and who's loyal to you personally.
Outside advisor through the prep: Cultivate advisors specializes in increasing enterprise value for selling. Running this prep solo is rough, the work compounds across multiple areas at once and most owners I know who tried to manage it alone either burned out or quietly dropped pieces that mattered. The advisor I was paired with had sold his own services business before joining the firm so the conversations had real texture from someone whod been on the other side of a transaction.
The pattern across this is that buyers price what they can verify, not what you tell them. Value building before sale is converting tacit knowledge into documented systems and relationships, harder than most owners expect, which is why starting 18 to 24 months out matters.
