admin methods

I've posted my simple Excel spreadsheet that I use to keep track of mainly invoicing, estimating & *estimates* of my expected tax. It's built around an Excel list with formatting to show the status of invoices & a summary page of totals & breakdown of income by client.

Feel free to improve on it but let me know as it would be nice to share those improvements.
