Wrike is an application that focuses solely on project management, and does not really have any help desk components. Here is a side-by-side feature comparison between OneDesk and Wrike.

In terms of pricing, with Wrike you need to figure out which features are in which plans and which add-ons. Then you need to call for pricing in most cases since only their-lowest level plans have published pricing.

With OneDesk you pay a flat fee for ALL our features, we do not make you purchase and connect multiple applications, modules, or plans. Our pricing is published and clear and ranges from $4-6 per user per month.
