General liability (GL) covers bodily injury and property damage caused to third parties — a client tripping in your office, a delivery vehicle damaging a client’s loading dock. Errors & omissions (E&O) covers financial harm caused by professional service failures — a missed tax deadline, faulty advice, a botched software implementation, an inaccurate appraisal. Most professional services firms need both. GL doesn’t cover professional mistakes; E&O doesn’t cover slip-and-falls. The two policies sit side by side and respond to entirely different claim types.
