And without being insulting to the general public, do not overestimate the levels of competence out there. If the software is to be sold as a "simple to use" piece of software, then the end users will, nearly by definition, have little or no experience of PC usage, other than general word/excel/email usage.
Expect a lot of support calls along the lines of "my PC crashed" or "my excel doesn't work" and it'll require a lot of time and effort to either solve their problems or convince them that it's not your fault/responsibility.
I do agree that there is a need for a small but simple accountancy package, but remember that the likes of Sage (with their First Books) is quite well established, easy (ish) to use and they have a lot of resources behind them.
For example, after the budget will you need to issue updates that the user needs to install to take account of new VAT rates, new PAYE rates and changes to the health and pension levies.
