        # Facilitate Invoice Validation — leveraging Document Information Extraction

[![REUSE status](https://api.reuse.software/badge/github.com/SAP-samples/btp-cap-dox-invoice-validation)](https://api.reuse.software/info/github.com/SAP-samples/btp-cap-dox-invoice-validation)

Invoice validation is often an opaque, manual, and error-prone process. It involves editing invoice PDF files directly, or sending them back and forth via email between multiple parties—

until the invoice can finally be approved for payment.

This sample tries to alleviate some of those pain points. It presupposes a clearly defined validation workflow. More importantly,

it simplifies and accelerates validation, allowing you to: copy over entries from the original invoice; correct entries; and then forward the invoice to the next person in line

in the workflow to validate it further. As a side effect, each correction and the rationale behind it is documented over time. To get an overview, please checkout the [teaser video](https://sapvideo.cfapps.eu10-004.hana.ondemand.com/?entry_id=1_cma51zr3) for this sample.

This invoice validation leverages _Document Information Extraction_ ([DOX](https://help.sap.com/docs/document-information-extraction/document-information-extraction/what-is-document-information-extraction?locale=en-US))

 —a service on the _Business Technology Platform_ ([BTP](https://help.sap.com/docs/btp/sap-business-technology-platform/sap-business-technology-platform?locale=en-US))—

and the _Cloud Programming Model_ ([CAP](https://cap.cloud.sap/docs/)). The sample runs entirely on BTP. Think of it as a separate extension to _SAP Central Invoice Management_ (CIM)

or _OpenText Vendor Invoice Management_ (VIM), rather than it trying to compete with the latter.

> [!IMPORTANT]

> The sample was built on AWS infrastructure on BTP. Therefore, we went with the Amazon S3 variant

> of the BTP Object Store service, while the CAP backend talks to the S3 via the AWS Client S3 SDK. Generally, the sample

> can also be run on GCP or Azure, if you slightly adjust the part of the code that talks to the Object Store, and use

> the corresponding store variant.
