Our tip

Digitize Your Incoming Mail

Do your business partners send you orders or invoices by postal mail? Change your channel of communication to fax.

Advantage for the sender: save time and money by sending digitized documents instead of postal mail.
Advantage for you: documents arrive in your inbox automatically digitized—from the very start and ready for the next step in the system or by an employee.
Benefits for both: faster processing, reduced costs, and a secure and traceable transmission channel.

Digitize your faxing now

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 in a department group mailbox. Send travel expense reports to accounting, quotations to purchasing, and confidential contract documents signed and encrypted to the managing director’s inbox…
With Retarus Smart Routing options, you define which document lands on which desk via the recipient number, sender number, or based on information in 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: with Retarus you can receive incoming documents directly in your business application. No need for manual digitization and uploading. Immediately upon receipt, you can view, check, release, link, archive, process, or integrate documents into your workflows.

Structured Instead of Unstructured:
Process Incoming Documents Automatically

Do your business partners send you orders and invoices by fax or email? Retarus’ Capture Services can receive even these documents in a way that your ERP system can processes 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.

By the way, using Retarus Capture Services means you have automatic access to a full-fledged EDI service. You can also integrate EDI-capable partners any time without having an EDI infrastructure of your own.

Our tip

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.

Retarus Fax Services: Your Benefits at a Glance


Seamless Integration

Whether you use an ERP, a CRM or a legacy system, Microsoft 365, or Google Workplace — thanks to open standards, you can connect Retarus Cloud Fax Services to almost any business or cloud application. For example, via RESTful-API web service or via standard interfaces and protocols such as SMTP, SFTP and HTTPS.


OPEX instead of CAPEX

Reduce your investment and process costs. Retarus lets you massively reduce or completely eliminate costs for telephone and fax infrastructures, fax servers, software, updates, administration, and maintenance. Retarus billing models (flat rate or pay-per-use) use fixed batch and page pricing, regardless of the duration of transmission.


Enterprise-Level SLAs

It doesn't matter if you are an international enterprise, a mid-sized company, or a startup. Choose the service level agreement that best meets your needs in terms of quality, support, and response time. We offer customized SLAs to guarantee special requirements, for example, the exclusive processing of your data in a special Retarus data center.


OCR and Barcode Recognition

Retarus' enterprise fax services enable you to seamlessly integrate faxing into your workflows. Read out information or barcodes from incoming documents with the Retarus OCR and barcode recognition feature and then use customized smart routing options to presort, forward, store, or process the documents automatically according to your rules.


Worldwide Telephone Number Service

Receive faxes anywhere in the world with local numbers. Retarus provides service and call numbers on all continents that can be managed and assigned easily in the EAS Portal. It is also possible to port existing incoming fax numbers at any time.

Our tip

Paper in hand, file in the archive

Do you need paper-based faxes? No problem. With Retarus you can print out incoming faxes automatically on any network printer or multifunction device. Simultaneously, these documents are available to you in digital form, ready to be archived or ready for other downstream tasks.
