Hi TLAWSON,
Smashing! I’m really pleased about this 
The schedule thing was only a bonus feature, I’m personally just looking for something simple and basic and what you have detailed would be perfect!
I don’t really know much about php or mysql but I’m guessing you will be adding a new table to the database, a new page (for the inputting of the expenses), a new page to display the expenses (or maybe just one page with all the functions), and probably a small modification to an existing page within Bamboo to add a link navigation to this “plugin”.
Would this be completely separate to Bamboo, i.e. no integration with Bamboo…? (does not matter either way, just wondering). It might be worth considering the future of Bamboo such as updates and how that would effect this “plugin” (I don’t know what this entails, but thought I’d throw it in here).
What you have listed is great and fits my needs, I have expanded a little more:
-Item quantity
-Item Price (I’m in the UK so we use the £, if that makes any difference)
-Ref#
-Company, or maybe “Bill Payee” (I think that’s the right term) incase it’s an individual rather than a company that is being paid.
-Date (Ideally reverse i.e. YYYY/MM/DD, but does not matter)
-Payment type (maybe a pull down option list)
- cash
- credit card
- cheque / check
- direct debit / standing order
- bank transfer
- other
-Comment
Although not too important, but I think it would be useful to be able to print off the entire list of expenses, this can just be printed though normal print in the web browser. So it might be worth considering an option to list all expenses in one screen for easy printing. A monthly or yearly view would also be cool.

PS. Although I can’t help much with the code etc… I can offer a small donation for your time (not huge, but at least something) as it’s a feature that would save me loads of time but most of all having this inside Bamboo would be so convenient!
