Every dollar of firm marketing decays except one: the client review. Ads stop working the day you stop paying. SEO drifts when the algorithm shifts. A five-star Google review from three years ago is still converting prospects today.
The math
The average small-business owner reads a dozen or more reviews before choosing an accountant, weighted heavily toward recent and specific ones. A single "she caught a $22k R&D credit our last firm missed" review outperforms a month of paid search.
What the top firms do
1. Earn the review at the moment of relief. The day the return is filed, the day the audit closes, the day the funding round is wired — that's when to mention the review, not in a follow-up email three weeks later when the emotion has faded.
2. Ask for the specific thing. "If you write a review, the detail that helps the next founder most is [the thing that surprised you about working together]." Reviews become concrete instead of "great firm, would recommend."
3. Reply to every review — publicly, in a human voice. Future prospects read the firm's replies as much as the reviews themselves. A partner-signed reply to a three-star review often wins the prospect over the five-star review it sat next to.
The tone
The reason it works is that it doesn't feel like a pitch. You're delivering good news, they're relieved, you mention it once, warmly, and move on. Anything harder and they never refer their friends either.
