A custom portal allows stakeholders outside your organisation to access your CRM system without having full access. Portals allow other users to access your services on a self-serve basis.
Users can access your services 24x7 whenever they want, giving you a competitive edge through superior customer service.
While interacting with you via your portal, users are required to provide information in the correct format, which can be pushed straight into your CRM. In short, portals improve customer service while saving a ton of admin work!
