At Localization Consultancy & Technologies we have adopted the subscription license model above the perpetual license model.
We would like to see ourselves as business partners and focus on a long-term relationship with our clients, and with such a license model we can react much faster on immediate customer requirements for new filters, or relative small product changes which may become critical for you and the relationship with your client.
We think that delivering an instant solution is what our customers are looking for so quick turnaround on solutions and filter updates when required, instead of the long term filter enhancements which are common in the localization business.
