[quote=flu]I use to work at intuit. Have you tried one of their solutions?[/quote]
FLU: +1. If your company is using QuickBooks (and, based on the size, it would seem ideal), you should look at the additional services Intuit offers, including payroll processing and quarterly/annual state/Fed tax filings, including 940/941 (Fed) and Form 100 (Ca. FTB).
I run an engineering company that is very contract intensive (meaning lots of paperwork, including Certified Payroll on bonded/Gov’t projects) and our CPA has everything on QuickBooks, including P/R and taxes. Saves time and money, as we need to spend very little on bookkeeping/CPA fees as a result.
