How Do Outsourced Invoice Processing Services Work?

Outsourcing invoice processing saves your accounting team the workload of digitizing and integrating invoices into your systems. For paper or electronic invoice processing, our software reads your invoices and extracts the header and line-item data you need.  

Invoices are typically saved in PDF format with full text OCR performed. Then the extracted data is attached as metadata. The extracted data can be formatted for your accounting, workflow, or document management system. 

Here’s an overview of our typical process:


We receive invoices by U.S. mail, fax, or email


Paper invoices, attachments, and envelopes are converted to digital images


Then, all relevant information is extracted electronically


Any questionable results or errors are then manually verified for accuracy


Finally, invoice data is attached electronically to invoices or as a separate file

Invoice Processing Services Save Time

Because we combine powerful invoice automation software with human verification, you get quicker access to invoice data than with traditional manual processes.


Connect with your accounting, email, and cloud providers for seamless data transfers.

Four Reasons to Choose BIS?

We’re often asked – why choose BIS? It’s a great question we’re happy to answer!


We grow with you.

The intelligent document processing software we use is available for sale. Because it is our own proprietary software, you can take it with you when you no longer need our services.

In fact, we have many options for this, such as:

  • Fully outsourced invoice processing services
  • Scanning-only and sending digitized records into your system, which is running our data extraction software
  • Onboarding the software into your organization for you to scan and process invoices

Our automation software processes more than invoices.

Do you also need contract abstraction, mortgage / lease processing, or any other document data services? If so, we can automate those processes as well.

Because we’re the software manufacturer and the services provider, we have deep domain expertise in data extraction and integration. So if project complexity increases, or your needs change, we are responsive and agile to tackle any issues.

Many of our data migration workers hold federal security clearances. In addition, we are a trusted vendor for local, state, and federal government.

  • “We use Grooper for a lot of accounting purposes, and for all the different types of invoices that we process. One of the reasons we like Grooper is that have one application built within Grooper for our whole accounting department. It contains seven different samples of the different kind of invoices we use, depending on if it’s a travel claim, or if it’s repaying a vendor, or something else. Grooper’s able to just recognize everything.”
