What application can integrate with Oracle for multiple invoice format submissions?

Hello,

We have many clients with specific requirements on how they would like to receive invoices. Is there a front end user application that you recommend, without technical coding, that will allow the manipulation of records, sums, etc to the format requested of the client? We currently have an extract from oracle producing multiple lines that then manually gets formatted in excel or db access that then is sent to the client. We are looking for a tool that will save these formats and accept the next monthly load. Any recommendations? Thanks in advance!
