Hi, Any suggestion on suiteapps or third party to handle rebate management in NetSuite?

At one point, NS had a SuiteSolution for Rebate Management. You could ask your NS or Partner rep if that's still around and take a look at it. It's been quite a while since I played with it, but as I recall, it dealt with basic rebate scenarios decently enough, but started to have trouble if there was a lot of complexity. Wouldn't hurt to check it out though.

Thanks Ryan. yes we have used it but for complex ones it requires lot of customisation. Hence looking for Suiteapps or third party which is made for rebate.

Ah sorry I misread your comment. I'm not aware of 3rd party ones.
