We are thrilled to announce the launch of the My DEISO platform at https://my.dei.so for our current and potential clients.

With their My DEISO account, our customers may now manage all their services, including all online services, training programs, files, training materials, projects, project milestones, tasks, invoices, online payment processing, and much more.

Moreover, My DEISO has a mobile-friendly platform that works with all smartphones smoothly. It’s a great feature for our customers because it makes it easier to manage their DESIO services and makes it easier for DESIO and its customers to communicate their work to each other.

Don’t hesitate to get in touch with us if your My DEISO account was not automatically created if you are an existing customer. A representative will assist you.

You can access your My DESIO account at https://my.dei.so.
