Bought 1 Tier. First impression: very detailed software but simple as well. Bought a couple of CRM tools on Appsumo earlier and tested them. What I like about Heffl at the first glance is its user friendliness and fast service. (Had a question, got immediate response.) I was looking for a very flexible CRM solution for my Consulting Business. I think I found it with this tool. There is a lot more within the software, though. Just focussing on my first impressions now. Worth a try. Five early tacos. Keep up the good work, Heffl Team!
