Quickbooks is easy to use and easy to navigate. I have been using it for years and find it is perfect for small to medium size businesses. It has many capabilities I haven't even used yet but from using it for many years, I have seen a big improvement in what the program is capable of.
I currently use Quickbooks with our other business software and it seamlessly imports everything we need. It also does this really fast and we've never had any issues with information importing to Quickbooks.
The financial reports are also so quick to create!
Quickbooks is not ideal for large or public businesses (lacks in controls), in my opinion. But this is fine because it is perfect for smaller to medium sized businesses.
I believe there are trials of Quickbooks available and I highly recommend trying it because you will be convinced. It's a great product that has gotten better over the years and continues to improve. It is also very affordable and has capabilities that make bookkeeping a breeze!
The business I work with now works in multiple currencies. Quickbooks handles this really well. I also find the tracking of capital assets very helpful! As the accountant for a small and quickly expanding business, I find that Quickbooks is able to grow as we do. It also produces very useful and easily customizable financial statements that provide my superiors to make important and informed decisions for the business.
