What feature allows you to collect and store documentation for clients in Xero HQ?

The feature that allows you to collect and store documentation for clients in Xero HQ is Xero Ask. This feature provides a secure and organized way to request documents and information from clients. It enables users to easily communicate and collaborate with clients, ensuring that the necessary documentation is collected efficiently. This functionality enhances the service experience by centralizing communications and document requests, making it easier for accountants and bookkeepers to manage client relationships and documentation needs.

Client Notes, while useful for capturing important information about a client, does not specifically focus on the collection and storage of documentation. A Document Management System, though closely related, is not explicitly mentioned as a feature in Xero HQ; rather, Xero Ask serves that purpose. Xero Support pertains to assistance provided by Xero rather than a feature for managing client documentation. Thus, Xero Ask stands out as the appropriate choice for collecting and storing client documents.
