Invoice firewall

How does it work?

The robot in InvoiceFirewall takes over the most time-consuming and trivial routine tasks in your creditor accounting and at the same time helps your suppliers to invoice you correctly – and completely digitally. Read below to learn more.

Automatic screening and error correction
InvoiceFirewall is located between your suppliers and your financial system. When a supplier sends you an e-invoice, InvoiceFirewall checks that all the necessary information has been filled in correctly. Some invoices with errors or omissions are automatically corrected by the robot. Other invoices InvoiceFirewall automatically sends the invoice back to the supplier with instructions on what to correct. The supplier corrects the submitted invoice directly in InvoiceFirewall and thus avoids sending a credit note and a new invoice. It is good service and happens completely automatically.

When the invoice is 100% correct, it is released for further processing in your workflow or financial system. No more hassle with incomplete invoices that no one will know by. It is you who decides the rules, and you can make individual rules on the individual supplier, if there are special considerations.

In this way, InvoiceFirewall ensures the best handling of incoming invoices – also from the point of view of your suppliers.

Automatic transition to e-invoicing
If all your suppliers are already sending you e-invoices, then you are already on target. However, many companies have a number of suppliers who still send invoices per email or letter mail.

Therefore, InvoiceFirewall is equipped with a robot that monitors which suppliers do not yet send e-invoices and receives information from efacto’s supplier network about whether the individual supplier is able to send e-invoices. At regular intervals, the supplier automatically receives an e-mail with an invitation to send e-invoices in the future. Automation and communication are defined by you, so you have control over, for example, whether some suppliers should still be allowed to invoice you in the traditional way.

With InvoiceFirewall, you also get a login with access to all purchasing data in a fixed and structured format, which will take months to pull out if you have to do document by document.

Does that sound too good to be true? Then read the customer cases on this page about how InvoiceFirewall saves time and creates an overview for other companies.

If you have any questions, you may have the answer in the FAQ at the bottom of the page. But you are of course also very welcome to get in touch via the chat or book an online demo.

Avoid extra work in your workflows

InvoiceFirewall reviews the invoice before it sends it to your invoice workflow. Our autofix robot fixes all known errors. In the event of missing details, the invoice is sent back to the supplier, who can correct errors without sending a credit note and a new invoice. No invoices with invalid/missing data enter your erp systems.

Fewer errors and less wasted time

InvoiceFirewall loads approved vendors from your ERP system every night. Only approved vendors that meet all of your invoice content requirements will pass through the firewall. Fraudulent invoices or incomplete invoices are stopped before entering your ERP-system.
