Your bills go out on time with a single click, and you reap the rewards of better cash flow – higher profits. SMART LEGAL CALENDAR & TASK MANAGER You might wonder what could make CosmoLex legal calendar software for law firms any better than one of the free third-party calendars. The answer is simple — Legal Calendar Software by CosmoLex can leverage its tight integration with the legal practice management & billing system to give you a smart calendar & task manager — that does a lot more than you’re used to. STREAMLINE CLIENT COMMUNICATION Most client disputes occur when clients claim that they were not informed about critical matter aspects — especially if you can’t document when, how and who at your firm addressed these disputed details with your client. The CosmoLex Client Portal puts an end to such disputes, by keeping your clients in the loop like never before, giving them access (that you control) to any or all case information. There is no cost to you or your clients, and you can revoke access to any item or the entire portal at any time. LAW OFFICE ACCOUNTING CosmoLex has built-in accounting - right alongside practice management and billing where it belongs. You can handle all of your business accounting and trust (IOLTA) accounting within CosmoLex, eliminating any need for third-party accounting software (such as QuickBooks™). Built-in accounting with automatic bank data feed not only saves time; it eliminates the common sources of error that come with keeping your books on a separate system. AND MUCH MORE!
