62% behind one office isn't 11 client relationships, it's one, and it's the seller's. Find out who introduced each of those 11 and whether any of them have a term, or whether they're month to month like nearly every content retainer. If they're month to month, $340k buys a 30-day revenue stream plus goodwill that lives in the seller's face.
Before anything else, demand a cohort table by month covering 24 months: client name, start date, monthly fee, end date, current fee. You want ARPU by cohort rather than client count. Price compression from AI shows up as renewal discounts and thinner deliverable packages well before logos disappear, so a flat 18 clients with ARPU drifting from $1,600 to $1,250 is the thing you're looking for, and it changes the multiple you should be paying.
The owner on camera is the structural problem. Those clients bought a person and a face they've trained their audience on. Quote that revenue separately, model it as at risk, and put it behind an earnout measured on revenue retained at 12 months post close rather than anything measured at close. Also read the assignment clauses in the client agreements. If consent to assign is required, you may need 18 signatures, and every one of those is an invitation to renegotiate downward.
Then the cost side. Two contract editors are your gross margin, and editors raise their rates when they notice new ownership. Confirm whether a $95k draw really replaces the owner's function, because if the seat is actually a creative director at $110k plus someone producing, the SDE you're paying 2.5x for doesn't exist. How you structure and treat the purchase is for your attorney and CPA.
