VICTORIA, British Columbia (TheStreet) -- If your business is like mine, you're terrible at following up on sales leads.

The Microsoft (MSFT) - Get Report (Stock Quote: MSFT) Outlook/Apple (AAPL) - Get Report (Stock Quote: AAPL) Entourage hammerlock we relied on to manage our business e-mail, calendars and contacts is now officially broken. The rise of free, Web-based tools and the need to cut costs has forced many of us to cobble together systems using Google (GOOG) - Get Report (Stock Quote: GOOG) Apps, Yahoo! (YHOO) (Stock Quote: YHOO) e-mail and our BlackBerrys.

Unfortunately, none of these will get business through the door. Keeping basic contact data up to date is still a challenge, and communications from prospects is far too easy to not follow up on.

So-called customer relationship management, or CRM, tools like, Microsoft Dynamic, Sage and SugarCRM help organize contacts, tasks and leads.

The phone calling features were particularly useful. You can track your customers' contact history and schedule calls, which helped me plan my selling day. I really liked the "end call" button, which prompted me to think about how the call went and schedule follow-ups.

(MSFT) - Get Report (AAPL) - Get Report (GOOG) - Get Report (YHOO) (SBUX) - Get ReportThe focus on simplicity comes at a cost: The company offers sales options that might not work for you.

Oprius, for example, doesn't support group sales. You have to go outside the system to split up contact follow-ups. There's also no reasonable way to sync your calendars and tasks on Outlook or Google with those on Oprius. BlackBerry and iPhone users would have limited access to their information.

Oprius is planning to add many features down the road, but I suspect a sophisticated sales effort could overwhelm this tool quickly. So before you sign up, make sure it can handle what you need it to do.
