My company attempted to implement FinancialForce (it was  CODA2go when we began the process) without success.  Contrary to what they tell you in the sales meeting before you purchase their sotware, the general ledger is not robust, the integration between SalesForce and this product is anything but 'seamless', there are size contstraints (number of items/lines) when creating an invoice, AP is sparse at best (try a check run with more than 10 checks - it doesn't work).  Very disappointing and a HUGE waste of time/money on our part before we gave up and chose another accounting solution.
