Good Morning.

Your question is one that many companies offering any kind of a software or service contract may face. That means there are at least several market ready solutions for you. I've had about 25 years of experience in selling, implementing and profitably tuning the business systems and software systems like this one, and for several years of that time, was an employee for Cognos and Oracle, as well as holding certifications as a CPA and CGMA. From this experience, I've placed (and been certified) for many of these kinds of software systems for companies serving their clients under a contract-for-service arrangement and renewals are only one important aspect of making them work well for you.

If you are a growing company, and have many clients holding these contracts, your best bet is to automate your business process as much as possible. To do this, you may want to consider the less expensive solution of extending your CRM System into a kind of contract management/field service software system. This extended system is designed to provide functionality that manages and tracks the services you may give to a client, but also tracks the contracts the clients pay for that same service. Features can be very rich, and may extend beyond what you need for simple contract management, however, seeing the services side of the contracts will allow you to view your costs of servicing your customers under these contracts whether by phone or by service technicians that travel. If you have SalesForce CRM (the gorilla of CRM's) you may want to inquire into ServiceMax as they have a system that may fit your need that matches the architecture and integrates with the Force.com platform and SalesForce's system.

Salesforce not your game? Then one source for finding lists of other different systems is www.capterra.com . Another source would be to inquire into your CRM provider and ask them if they have created any contract management/field service management software modules that integrate with their system. A third place to look is to google the Gartner Magic Quadrant for Field Service Management systems. This report, while there is a fee, will list many of the players in this software space and their strengths/weaknesses.

Good Luck!
