PerBI is available under a fixed price quarterly licence agreement.
This allows you to try the software at a minimal cost and us to eventually make a profit.
Once we have received a purchase order
we will supply a licence file along with the first quarter's invoice, after this the licence fee is automatically billed quarterly in advance.
There are no long term commitments the licence agreement can be cancelled at the end of any quarterly period.
Updates to PerBI are included in this licence, they will be made available for download at your expense.
