The best thing about this product would be its accuracy.It makes sure that I'm always paid correctly every month! This has been extremely accurate so far with no problems to report whatsoever.
There are few things which could improve upon but nothing major at all considering everything works just fine as it should. We use SAP BIllings Pro mainly because we didn't want any third party integration or extra expense when using our own system. The benefits include being able to view invoices online directly rather than waiting through mail delivery like other services have required us too do previously; plus it's easy enough for even those who don't have much technical expertise themselves yet can still get up-to-date information without having to depend fully on IT support staff to see if payments went out etc.
