Clients insisting on using Standard Oracle features

I was mildly surprised when a top fortune client of ours insisted that we study their existing financial system and come out with a solution which is possible using standard Oracle Apps Financial module features. The fact that the organisation is ready to alter their existing financial process if necessary is very encouraging. I feel this trend amongst large organisations not to deviate too much from standard features available in Oracle Apps is catching up. Personally I think, if the organisation is asking for too many customisations, then there is a problem with the business process that they are following. However, not all organisations are ready to accept that the business process they are currently following is inefficient and fraught with inherent problems. Hopefully we would be able to provide a great solution though within the stringent time lines :)
