If you are running your own business, it can be a really good idea to make your life as easy as possible by using a selection of tools. For example, I save money by doing my own books and because I have done several courses on how to do this, I use a spreadsheet package and find it all very simple. However, some people use bookkeeping software. It can be a good idea to do this as it can save you a lot of money in paying a book keeper.
You may still use an accountant for some tasks, but if you can keep your own records it will save you lots of money. Some people even use the account to do their book keeping and this is extremely expensive as they charge a lot of money. So it can be worth paying out money for software like this as it can save you a lot of money in the long term. Just make sure that you use it!
