CRM software, like the product Close.io, is helpful for tracking customer information. Emails can be sent and received with ease, and users can use Close.io to track them automatically. No manual data entry is required, which ensures that less time is wasted on managing the sales workflow. If making phone calls is a need, it can be done so with a simple click. Once the phone rings, lead activity information comes up automatically. Multiple pricing models are available, including basic, professional, business, and enterprise options. Differences between the packages center around bulk email sending, call transferring, voicemail drop, call audio recording, and other features related to lead follow-up.
