There are some very interesting new online accounting packages available. Wave is a free one and Xero, which I use, is paid for. I only opted for Xero over Wave as it had the multiple currency option which I needed. Otherwise I would have been opting for Wave. Can't see the point in paying for accounting packages when free ones with better functionality exist. I used Sage, Quickbooks, Big Red Book, to name but a few in the past. Each has been cumbersome and outdated in comparison to Xero. The online systems are constantly updated. Some people have security worries over online housed accounts, but I think it is the way forward. Both offer comprehensive options and relatively easy to use systems. The handy thing is the Co you are doing work for can log in and upload things like invoices, expenses claims, without having to go through you. Also if an accountant needs to look at something, they too can log on. Also you can access your accounts from anywhere, not just your computer. Might be worth considering.
