how much would it cost us for you to invest the time to test? We would look to cover this cost. We want to put 30 new customers onto KReports extension so the costs can be recovered through these sales.
Today its nearly working. The reports can be configured on multiple tabs and 50% of the time they work so KR is not far off a solution. It just needs to work every time because, by its nature, if it only works half the time, the users (at best) just switch off but more often complain and demand a refund - claiming they have been mis-sold.
