gday - just looking for some recommendations for some online billing software. (preferably an open source php/mysql solution). i need to be able to bill clients on a monthly or quarterly basis (when they license our software products). plus would like to have it so they can view and pay invoices online (integrated with world pay etc).
i have had a look at modernbill which looks like a good solution - but would prefer something open source if its out there.
thanks tim
