Ready for Any Workflow: Today and Tomorrow

We receive your incoming fax documents and digitize them for you. At the right place, in the right format. Ready to go for the next steps. You don’t have to invest in any additional hardware or software. Simply connect to the Retarus Enterprise Cloud and get started. What’s more, you are automatically equipped for the next generation of technology: connect once and new requirements for your method of communication can be implemented quickly and easily at any time.

Digital Instead of Analog:
Receive Faxes in Your Email Client

Receive faxes directly in the responsible employee’s email client or in a department group mailbox. Automatically ensure that travel expense reports get to accounting, quotations to purchasing, and confidential contract documents signed and encrypted to the managing director’s inbox.

With Retarus’ smart routing options, you can easily set up and optimize your digital fax workflows: You define which document lands on which desk via the recipient number, sender number, or based on information within the document itself—read by OCR and barcode recognition. No need for manual digitization, pre-sorting, and distribution. The documents are available in digitized form upon receipt. In exactly the right place—where your employees process them.

At the Destination Instead of en Route:
Receive Faxes in Your Business Applications

Whether you use ERP or CRM, an enterprise content management system or document management system, SAP, Microsoft or legacy, whether in the cloud or on premise: Thanks to Retarus, implementing digital fax workflows is simple and incoming documents can be received directly in your business applications.

Structured Instead of Unstructured:
Process Incoming Documents Automatically

Do your business partners send you orders and invoices by fax? Retarus’ add-on Intelligent Document Processing service can receive these documents in a way that your ERP system can process them automatically. Here’s how it works: We receive the documents for you, read the data using highly intelligent recognition software (OCR, ICR, and IDR), convert them into the target format, and transfer them (including the original document for the archive) to your systems.

You benefit by saving time and preventing data entry errors in your ERP system. The degree of automation increases and costs sink. All this without having to invest in hardware and software, without needing a WebEDI portal and without having to convince customers and suppliers to use a new transmission channel.

Ready for All IP

With Retarus, faxes are not sent via the VoIP infrastructure of your telecommunications provider, but rather directly via Retarus data centers. These centers are connected redundantly to multiple Tier 1 carriers and the bandwidth can be scaled as needed.

With Retarus, connection failure or erroneous sites are things of the past. Irrespective of how high the fax volume is.
