Copying a post I made over on PropertyChat - CRM Software Insightly gets good reviews - #1 Free CRM for Small Business: Online Customer Relationship Software ... but there were a couple of things it couldn't do that I needed (specifically around handling multiple brands / email domains), so I gave up after only a few hours of my free trial. I'd suggest giving it a try anyway - it's pretty cheap I think and may do what you need. The UI was pretty slick from what I saw - if my business was more simple than it is, I would give it more of a trial. I ended up going with Close.io - Close.io – Stop logging calls and emails and start making them instead. ... it's much more focused on inhouse sales teams (using VoIP and email) rather than a generic small business CRM and is missing a lot of the other functionality you might be looking for - but I mostly just use it for email, so it suits my needs (and works really really well for email integration - the best I found out of any of the systems I trialled). My CRM needs are very specific, so what I found worked for me isn't what works for many service based SMBs. Some links to help (or make things worse!) Best CRM Software in 2016 | G2 Crowd Other CRMs I've seen fairly good reviews of are: Nimble: Social CRM Simplified. | Turn Communities Into Customers. (more focused on social media) Pipedrive: Sales CRM & Pipeline Management Software (focused on pipelines/deals) ZohoCRM - CRM software, customer relationship management - Zoho CRM (part of a larger suite if you want a lot more functionality) SalesForce IQ - SalesforceIQ for Small Business CRM & Productivity Apps for Sales Teams ... this is SalesForce's SMB offering - I've read fairly good things about this too. ... wondering what CRM systems people here use?
