The initial setup is quite complex. Most of our customers can't deploy SWIFT interfaces by themselves and they need help from certified engineers.

It's complex as is. The SWIFT system is complex.

The time it takes to deploy will depend on the project. It can take anywhere from one to seven days. If it's for an integration then it will take longer. 

The users are from smaller financial institutions to very big banks.

In some cases the deployment will require one person for one part and up to 10 people from the customer's side; if customers have a complex infrastructure and different people are responsible for different parts of this infrastructure, then it will involve more than 10 people.
