The verdict
For a small B2B team with steady traffic and a process for fast follow-up, I'd pick Leadinfo. It shows which companies browsed key pages yesterday, and the speed from website to CRM is what pays back.
If calls drive your leads, you spend on ads and you need a source for each one, pick CallRail. That is true for trades, clinics, legal firms and home services, and the agencies that serve them.
My default for readers of this site is Leadinfo. Solid Growth is a certified Leadinfo partner, so weigh that. Check that Leadinfo covers companies in your target countries during the trial.
