Although the customers of Yu Quan Chain Home have always emphasized SAAS deployment in their publicity, they can arrange it as long as you have the requirements of localization deployment. After all, their company, Yu Quan Science and Technology, is also an established enterprise that has been a call center in Southwest China for more than ten years, and basically belongs to a large customer who needs customization. The technology of localization deployment is still very mature, don't worry.
But to be honest, if you want to be a customer service system now, you still recommend SAAS, which is lightweight, quick to deploy, less investment and relatively simple to maintain later. If it is deployed locally, the whole will be much more complicated. Personal suggestion, the landlord can reconsider.
