I use GnuCash for all my personal finances. Anything is easily entered. The article is fair summary of features and benefits. (I've used Quicken for several years before GnuCash. I've never had a reason to go back to Quicken.) For a small business, and many of us have a small business, it is still wonderful. However, it does not have a payroll tax calculation or sales tax recording features. Yet, even if you have employees, and if you use a payroll service, GnuCash can still meet your needs (simply create accounts and enter payroll data to detail level you desire). For sales tax, it can be as simple as transfer of output from your cash register into GnuCash accounts and send in form as required (last I used Quickbooks, you still had to fill out sales tax information manually into a paper or on-line form). »
