so they can pay with paypal there and then or other ways

login multi user. Invoice personal

Able to set the currency per client and/or invoice, instead of only as a general setting.

I work with clients from different countries and, of course, different currencies, and it would be cool to bill them in their own currency.

someway user can choose which company the invoice created from

in germany we have to define the service period in invoices.

therefor it would be great if the start date would be automatically set to the next (following) start date.

Create a mobile browser interface for the iPhone etc.

Simple reports of income for a given period of time would be useful for doing taxes later.

A nice little thank you email when the payment is marked as paid would be nice!

When I came back to my first testing invoice I noticed the order was different than I saved it and I couldn't see the logic in how it was sorted.

Let the user sort the items in an invoice, and save that order.

- Preferably with dragging & dropping (AJAX).
- Alternatively with a new editable column up front for the item #.

It would be sweet if you could have a helpful auto-update function that took care of all the updates (i.e. WordPress)

3 things are important to an invoice software:
1. Quote
2. Pro-Forma
3. Credit Invoice ( returning goods )

When nr.1 and nr.3 are in SiWAPP, we step over from our software to SiWapp.

I'd like to change what it reads at the top of the invoice - instead of 'invoice #1' etc.

There should be option to send Invoice to multiple eMail IDs. And a copy of mail should be sent to the Siwapp user also.
