Revenue mix. Recurring business work (monthly bookkeeping, payroll, business returns with year-round contact) reads as durable revenue; seasonal 1040 volume reads as a book that has to be re-earned every spring. Broker commentary consistently treats recurring-heavy books as commanding stronger multiples, though the premium is directional in the published material, not a quoted number. Treat claims like "1040 books discount 10 to 20 percent" as industry folklore: widely repeated, never cited.
Owner dependence. If every client would name you as their contact, the buyer is buying a job with your name on it. Transferability is the product; key-person risk is its biggest tax.
Fee levels. Underpriced books invite a repricing-risk discount: the buyer assumes attrition when fees normalize. Ironically, raising fees before a sale often raises the multiple and the base it multiplies.
Documentation and books. Buyers of accounting firms read financials for a living. Undocumented process, messy internal books, and no clean client-level revenue data do not lower the offer; they usually prevent one. That failure mode gets its own guide.
Structure, the quiet variable. Headline multiples and deal structure trade against each other. A 1.2x ask with a long earnout and retention clawbacks can be worth less in hand than a 1.0x deal with more cash at close. When a seller anchors at the top of the band, buyers respond with the most buyer-favorable structure; the two never stay at their best simultaneously.
One warning on EBITDA stories. The PE consolidation narrative ("8x EBITDA!") applies to platform-scale firms, generally $2M+ of profit with management depth. Applying platform multiples to a sub-$1M owner-operated practice is how sellers talk themselves out of every real offer they get.
