Time Matters is practice management software, produced by LexisNexis which was purchased by Reed Elsevier in March, 2004. It differs from contact management software such as ACT! or GoldMine because in addition to contacts, it manages calendaring, email, documents, research, billing, accounting, and matters or projects. It integrates with a variety of other software products from both LexisNexis and other vendors. Some of these vendors are Quicken, Microsoft, Palm, Mozilla, Corel, and Adobe. Developed originally for law firms, Time Matters competes with Gavel, Amicus, Tabs, and other legal practice management products. It also may be used in conjunction with Document modelling and Document assembly software products like HotDocs and Deal Builder.
