You’ve spent years building something real. So when it’s time to put a number on it, the last thing you want is a surprise. Yet founders make the same business valuation mistakes over and over, and most don’t find out until a buyer’s already at the table.
TL;DR: The three biggest business valuation mistakes are chasing revenue instead of profit, misreading EBITDA multiples, and skipping expert help until it’s too late. Fix these early and you’ll walk into any deal with real leverage.
Why Doesn’t Revenue Growth Always Mean Higher Value?
Here’s the thing nobody tells you early on: growth for growth’s sake can actually hurt you. Buyers don’t pay for top line numbers, they pay for quality, sustainable earnings. We wrote a whole piece on this because it trips up so many owners: Why Growing Revenue Can Still Lower Business Value. If your growth is coming from thinner margins, one off contracts, or customer concentration that keeps you up at night, a buyer will see right through it. Fast growth looks great on a slide. It doesn’t always look great on a cap table.
What’s the Biggest Mistake with EBITDA Multiples?
Founders love to talk multiples (“we’re worth 6x EBITDA!”) without really understanding what goes into that number. Here’s the problem: the multiple means nothing if your EBITDA isn’t clean. Add backs, one time expenses, owner perks running through the business, all of it needs adjusting before you apply any multiple at all. Our guide on how to calculate EBITDA multiple breaks this down step by step (trust me, it’s worth the read before you talk numbers with anyone). The Business Development Bank of Canada has a solid rundown too, on common mistakes when determining company value, including applying the wrong multiplier entirely.
Why Shouldn’t Founders Skip Professional Guidance?
This is probably the most expensive of all the business valuation mistakes on this list. Trying to eyeball your number, or worse, anchoring to whatever a friend’s business sold for down the street. Every business is different. Industry, growth trajectory, customer mix, all of it moves the needle. Harvard Business School’s breakdown of valuation methods is a great primer if you want the mechanics. Forbes recently made a similar point in their piece on mistakes owners make before selling. Founders who wait too long to get outside eyes on their numbers almost always leave money on the table. We covered the real world side of this in How Much Should I Sell My Business For?, a question every owner asks eventually (usually too late).
Getting It Right the First Time
Look, nobody expects you to be a valuation expert. That’s not your job, running the business is. But avoiding these business valuation mistakes now, before a buyer, investor, or partner is in the room, puts you in a completely different negotiating position. I’ve seen founders leave six or seven figures on the table simply because they didn’t know what they didn’t know. Don’t be that founder.
