Customer Relationship Management Tools are big business. You can see examples in vast and expensive solutions like SalesForce.com. However, not every answer is world-class and focused on the enterprise customers. There are also plenty of options all the way down to the free and low-cost arena. We will look at some of these contenders that not only can serve your needs. They also can be easier to implement than SalesForce.
https://www.insightly.com - Pricing: FREE for up to 2 users with 2,500 or fewer customer contacts. The Paid plans range from $29-$99 per user per month.
http://www.nimble.com - Pricing: They keep it simple and have only one plan. $19 per month per user. This has an unlimited number of customer contacts allowed.
http://www.zoho.com/crm - Pricing: The Paid plans range from $12 - $100 per user per month.
https://www.bitrix24.com - Pricing: There is an entirely free account (cloud based), you get five users and 5GB of storage. The vendor also offers an installed option for a one-time fee of $2,990, which gets you their small-business installed CRM (good for 50 to 500 users). If you need a system that has telephony and project management and don't need a lot of handholding or the most natural UI this is a good option. Overall, I found Bitrix24 to be powerful but a bit slow in responding to requests. On the other hand, they have great import tools.
https://capsulecrm.co Pricing: Capsule is free for up to two users with 10MB of storage and 250 contacts. I found it to be easy to use and easy to learn. The mobile-responsive site appears easy to use as well although I did not spend much time with it. This is a simple interface and product but strong on the functional side.
https://monday.com - Pricing: $25/month for up to five users. It is an elegant solution but more project management focused than a CRM.
