What agencies actually need
Agency commercial life has a rhythm that most CRM products were not designed for. Work arrives through referrals as often as through outbound. Pitches take weeks and then decide in an afternoon. Retainers renew quietly or lapse quietly. And the people with the strongest client relationships are usually billing on other work.
The consequence is that an agency CRM is judged on two things: whether it holds relationship context reliably, and whether it can be kept accurate by people whose main job is something else. Feature depth comes a distant third.
