SAP Concur integration with Sage 100 Contractor for invoices?

We'd like to use Concur with S100C, but the Trimble (Ryvit) DataXchange connector only supports expense reports, not AP Invoices.  Has anyone found a way to get them to work?  I asked Accordant, our Sage Partner, but they said it won't work and recommended switching to Intacct.  Not that it works there either.

Thanks in advance!
