Logical Office and CCH Central Can Chat
Typically it's software used for "Custom Relationship Management", i.e. keeping on top of your clients, contacts and prospects, and ensuring you are telling them everything relevant!
Most worthwhile practice management systems are capable of handling certain elements of CRM, so we normally advise not purchasing a CRM system, unless your existing systems are not capable.
That being said Logical Office has some fine capabilities, so we have built some integration which ensures your data is kept in sync between both systems. If you'd like to know more, please get in touch.
