Confidential information? How to exchange sensitive documents securely and easily
Confidential exchange of sensitive documents
With SecureExchange, using traditional emails to exchange sensitive documents such as wage statements or account statements to prepare tax returns is a thing of the past. Receiving and sending annual financial statements and the like is encrypted end-to-end.

Secure upload & download areas for clients - without creating an account
Complicated login paths can often act as a deterrent for customers. SecureExchange therefore allows access via a secure link and two-factor authentication. Clients can easily access the customer area to upload sensitive documents.

More efficiency & minimized risk of errors
The integrated completeness indicator ensures that clients submit all requested documents in full before the processing procedure is continued. This means you are no longer slowed down by incomplete dossiers - for more efficiency in case management.

Confidential, customized management of customer cases
In a central workspace, you can flexibly create and manage individual customer cases and thus keep an eye on all mandates and the associated documents.

Digital delivery of sensitive mandate documents - end-to-end encrypted and audit-proof
Secure logging of every document transmission
Full traceability is guaranteed thanks to audit trails, delivery and read confirmations for every document sent. In this way, you not only meet regulatory requirements, but also improve transparency and ensure trust among your customers.

Paperless transmission of accounting documents, annual financial statements & other mandate documents
Say goodbye to manual, paper-based processes that drive up costs and create inefficiencies. With Postbox, you not only deliver mandate documents efficiently and securely, but also digitally in compliance with the GDPR.

Permanent and unchangeable storage directly in the mailbox
Annual financial statements, accounting documents and other sensitive mandate documents are stored long-term, unalterable and outside your access area as trustee after transmission, which means they automatically become the property of your clients. Once documents have been provided, they can no longer be changed.

Flexible integration into existing systems
Do you already have a client portal in use? The decentralized postbox can be easily integrated into existing systems so that your clients can access shared documents directly in their familiar environment. We take care of the data residency and guarantee maximum security - you can concentrate on your core business.
