We added some features for Quickbooks 2002, 2003 etc... First of all you can send more or less all items from Quickbooks by email via your email account. You can email not only invoices. Other items ready for email are credit memos, purchase orders, statements, sales receipts and estimates. All this can be one by a few mouse clicks. If you don't like the layout of the invoices or estimates, you can - not so easily - change it. For any help, just contact us. We also added another most interesting feature. On request we attach the information contained in your email as XML document. XML is the new standard to exchange information. With XML your customer can process this information and - with an upcoming tool from us - add it more or less automatically into Quickbooks. This type of information exchange is a new dimension of reducing the paperwork in your office. ... and there is only one reason why we did it. We use it by ourselves. We didn't like to enter bills and estimates into our system and create invoices or purchase orders, print and mail them.
