While they compete for same customer base, Xactly is more suited for quick setup/easy calculations, where Synygy is a more robust tool for complicated transactions. Both products are capable of completing many of the same tasks. During the evaluation process, we did not grasp administrative differences so selected a product based on price. In retrospect, implementation costs for Xactly were higher than the time and materials estimate - the actual cost difference between two products came out much closer than initially expected.
Well suited to support simple plans with large populations, frequent pay processing. Key questions during selection: What capability exists out of the box? If not out of the box, is it possible to produce requested content? How much can we (company) do without requiring Xactly support & what impact does Xactly support have on our delivery turnaround?
