Simple Billing System

I have a database of customers, i'd like to be able to send an email invoice to them and then be able to check off whether they have paid or not and what payment method. I'd like to be able to edit the amount on the invoice, description (with a default description) and also the date due. i have an invoice template to use. this can be a pdf or as a html email. i'd like to schedule an overdue invoice if the first one is not paid. then a second notice after a certain period also. ## Deliverables * * *This broadcast message was sent to all bidders on Wednesday Oct 27, 2010 12:24:37 AM: Hi, i've made screenshots and extended the scope of this project. Please let me know how i can send this to you.
