A quick plug for a piece of software I've been using for the last couple of months to record our church's finances. The package is Manager. It handles GST calculations and reports, seems OK for small, manual payrolls, is free, works on multiple platforms and seems to conform to standard accounting principles. It also has a very active forum and many guides have been written for common tasks.
Overall it will fit the bill for monitoring our church finances and produces a range of Profit and Loss and Balance Sheet reports. There is a cloud-based, multi-user system available, but since I'm the only person who needs the software, the single-user free version works for me.
