We pay yearly. We made our deal a long time ago, and it was for a perpetual user license, which essentially works out to three concurrent licenses. We can have as many people in the client as we want, as long as they're not using it at the same time. That works out fine for us because I have 10 people on my team and they don't go in there simultaneously. So all 11 of us can use the tool just fine but we only pay for three licenses. 

I believe we also pay a fixed maintenance cost for the Evolve part, after we bought it for a fixed price. But it's not a named license so anybody in the company can use it. If we grow to have more people, they can use it.

Collector, which is the integration API tool, is a third type of license. 

I estimate that we pay between $40,000 and $50,000 a year for the solution, not including the upfront costs to buy things the first time.

The cost is something like $15,000, per license. But I haven't looked at those numbers in three years. It was over $100,000 to initially set everything up and get it all configured.

In addition to the standard fees there's the hosting cost. That's something like $1,000 a month.

Yearly, our cost is €100,000.

On a yearly basis, our licensing costs are 50,000 euro. There are no additional costs because we are on a SaaS model.

The licensing enables you to differentiate between people who edit the content and the people who consume it. We are able to keep the licensing costs down by keeping the "contributor" licenses to a minimum, and we then just roll out the content in a read-only version for the rest of our users. They're able to view the content with just a Social license.

Unless you are a one person shop – always go with the Workgroup edition and Concurrent licensing, that puts your models in a database for protection and allows the team members to share a license.

I think erwin is quite expensive. I have difficulty selling the portal, in fact.
