I have a small salon business whats the best crm system
Since you have a small business, I'm assuming you would not want to spend a ton of money on a CRM. Here are a few options. There is Zoho CRM where it is free for up to 3 users and it can range from $12-$25 per user after that. This is the closest alternative to Salesforce, it offers managing customer support, inventory, and marketing efforts and much more.
Another option would be Base. It manages and customizes the stages in your sales pipeline. It identifies strengths and weakness of each sales rep as well as your whole team and much more.
