I have used a spreadsheet (best reserved for a tiny operation), GnuCash (free open source but has a learning curve), Quickbooks (pretty much the standard, but not specifically built for farming) and now Traction. After 10 months of using it, I'd recommend looking into Traction. It's built by a team knowledgeable about farming and comes with excellent support. They are continually rolling out new features, some specifically for farming, as well. It not only offers accounting, but whole farm management.
