8 Things a Good CPA Does That You Don't Know About

8 Things a Good CPA Does That You Don't Know About Your CPA files your taxes once a year and sends you a bill. A good CPA stops you from lighting money on fire before the audit even starts. The difference isn't subtle. It's the difference between someone who processes paperwork and someone who actually runs your numbers like they own the place. If you're a founder, you need the second one. Chances are, your current CPA does almost none of what's below. That's not their fault—most CPAs work reactive, not proactive. But it's costing you. Here's what separates them. 1. They Flag Zombie Subscriptions Killing Your Burn Rate You signed up for a design tool in Q2 of last year. Paid the first month. Never used it again. The credit card got charged 11 more times. You didn't notice. Your CFO didn't notice. Your CPA probably won't mention it either—unless they're the proactive kind. A proactive CPA runs your monthly bank statements against your books and spots patterns. That design tool. The Slack workspace you killed six months ago. The analytics platform you replaced.

We need to talk about margin." Catching this three months early instead of in your annual review is worth paying their retainer. 3. They Cross-Check Your Bank Statements Against Your Books for Discrepancies Reconciliation sounds boring. And most CPAs treat it that way. But a proactive CPA doesn't just reconcile—they investigate when the pattern is off. Why did a $12K invoice get recorded but the money never hit the account? Why does your bank show a wire out that doesn't match any entry in the books? These aren't always errors. Sometimes they're early signals of fraud, double-billing, or customer disputes you didn't know existed. You'd catch these eventually. A proactive CPA catches them first, in real time. 4. They Alert You When an S-Corp Election Would Actually Move Your Net Take-Home Every CPA knows S-corp taxation is an option. Almost none of them bring it up proactively to the founders paying them.
