Saleforce.com is an indispensable tool that allows you to manage your customer base in a simple yet flexible way. The only complaint I ever hear comes from new users. Using a new piece of software is like walking into a ghost town, there is no content available to get the full functionality of your investment. Then the tedious task of entering all of your existing information begins.
If you use Quickbooks, you can avoid this headache by adopting DataSynch with your new Salesforce account. During our initial integration, we will populate Salesforce with all of your existing Quickbooks data. So if you've been using Quickbooks for a few years, you can immediately enjoy all the functionality Salesforce has to offer.
