Issue

Syensqo currently use Readsoft's Currently use Readsoft solutions for Invoice processing and this . This covers two areas of functionality:

1. Readsoft Process Director for Invoice Management: Processes and approves supplier invoices.
2. Readsoft OCR: For scanning paper and PDF invoices into the system.

Situation: With the move to S/4 HANA Private Cloud, this setup needs review to see which tools work best for the future setup.

Recommendation

The recommended option is to:

• Use

• OpenText VIM for Invoice processing

• in S/4HANA, as it provides superior native Fiori apps to give users a more consistent look and feel aligned to the overall UI of the S/4HANA system, and
• Use OpenText OCR for invoice parsing to ensure better compatibility with the OpenText VIM add-on to S/4HANA. 

Additionally it appears that OpenText's solution will be more cost-competitive compared to the existing ReadSoft product being used today. 

Background & Context

Invoice Management Tool and Invoice approvals

All Supplier Invoices have to be processed by the Invoice Management tool - it validates the invoice data and runs any approvals queries etc for Supplier Invoices before posting htem them in the SAP Accounts Payable module for payment..

Invoices flow from suppliers into the Invoice Management tool from a number of sources

Image RemovedImage Added

All of these processes will need to continue to flow into the Invoice Management Tool regardless of whether Readsoft or OpenText is used.

Supplier invoices coming into Syensqo will need a process to approve invoice in the following scenarios

• Invoice Validation - PO, Vendor Numbers match up
• PO Based Invoices where there is a price discrepancy
• PO Based invoices where there is a quantity discrepancy or no GR has been entered
• Non PO Based Invoices that need to be coded to a cost object and approved by  the cost object owner
• Invoices where there is a query (eg Tax calculation)

Users will need a tool in S/4 HANA (essentially a Fiori App) to send invoices for processing and approval and for approving/rejecting the Invoices.

OCR

Tool

OCR (Optical Character Recognition) is used to scan PDF and paper invoices into the Invoice  Invoice Management Tool. Whilst an increasing number of invoices will be received via interfaces and so not need OCR scanning, there will always be a residual requirement to bring paper and PDF invoices into the after some kind of OCR processing.

Technically both Readsoft and OpenText can supplier both or either component, but using differnt vendors (eg supply both OCR tools & Invoice Management tools and these can be deployed independently, e.g. using the combination of Readsoft for OCR and OpenText for Invoice Management) . This leads to a more complex system and incerased increased licence costs. So its it's recommended that the same vendor be used for both. See Assumption section.

The more important decision is the invoice processing - as all invoices that come in will need to go through the processing, but only invoices that are scanned (ie not EDI, Ariba Network, Govt Portal etcnot in a digital machine-processable format (e.g. paper or PDF) will go through the OCR system.

Options

1 - No Invoice Approval Tool

• • Continue with current OCR setup
  • Likely impractical due to high invoice volume. 
  • Does not meet the process improvement objectives of ERP Rebuild. 

2 - Non-SAP 3rd Party Tool

• • Not advisable Significant due to likely significant effort to integrate with S/4 HANA Cloud and Fiori UI. 

3 - SAP-Recommended Tools:

There are two common choices; these will be evaluated in this document.

3a) Readsoft:

• Handles both scanning and invoice processing
• Currently installed globally - Syensqo has system experience and is currently integrated to many invoice flows

3b) OpenText

• Handles both scanning and invoice processing
• Not currently
installed/integrated
• used by Syensqo
• SAP's preferred option (marketed by SAP as "SAP
IM)Strategic agreement
• Invoice Management"), with long-standing strategic alignment between SAP and
OpenText
• OpenText 

Key Points

• Readsoft and OpenText offer very similar functionality
• Both can handle OCR scanning and invoice approval
• Syensqo already already uses Readsoft - so is trained in it has built interfaces for italready uses Readsoft; key users and IT support teams know how to use the tools. 
• OpenText is marginally Opentext currently is better integrated to S/4 HANA 4HANA Private Cloud Edition (uses Fiori Apps, cloud native architecture)

Assumptions

• OpenText and Readsoft are close competitors and both are credible solutions for Syensqo as an invoice management tool. Currently OpenText is better integrated into the S/4 HANA Cloud architecture and uses Fiori Apps. Readsoft has stated that they are developing the same tools, so we can assume that as a strong competitor Readsoft will match OpenText in this area before go-live.
• The volume of invoices that will require some kind of approval will be too high for a purely manual process, so not having any invoicing tool is not practical

Non SAP Tool

A non SAP recommended tool is not viable due to the expected effort to integrate with S/4 HANA.

• Using a tool not recommended or certified by SAP as being able to be integrated into S/4HANA is not advisable. 

Different vendors for Scanning Different vendor for scanning and Invoice Management

Whilst its technically possible to use a scanning tool from one supplier and an invoicing processing tool from another it does cause issues.

The use of two different systems run by different vendors means there are are:

• Potential gaps with dataflows, error handling & workflows
• Custom integration/Middleware
• Compatibility issues
• More complex implementation
• More complex Upgrades & Patching

In addition OpenText gives both OCR and Invoice Processing as a single licence.

• Potentially higher licensing costs

So there would be a cost implication to using Readsoft for OCR and OpenText for Processing.

Constraints

The Invoice Management tool should be be able to: 

• Able to handle invoices coming into the system from a number of sources - eg eMail PDF scans, Government Portals, SAP Business Network, EDI Inputs
• Able to ID identify the correct approvers and transmit Invoices to them with minimal manual input

Local governments can mandate the use if an Invoice Portal for all invoices to be passed through - so the system will need to be compatible with this.

The system should be able to receive inbound invoices from multiple sources - eg Portals, SAP Business Networks, EDI etc 

The system should be certified as compatible with S/4 HANA Cloud Private edition.

Impacts

If the invoices are not processed, approved and paid in a timely fashion then the suppliers of Syensqo may begin to refuse to supply Syensqo and so cause disruption to the business.

This means that the Invoice Management tool must no not have errors or lost data due to 

to unreliable inbound interfaces from all the inbound processes and

networks.

Business Rules

• All PO related Invoices that have differences outside of tolerance levels will require approval. 
• Invoice payments on time are tracked and monitored for compliance with local prompt payments standards so timely payment is a requirement.

• Local governments

• may require all invoices to be

• processed through an Invoice Portal, necessitating system compatibility with this mandate.

Options considered

The following options were considered. Both of these are part of "Option 3" in the Background and Context section above. The choices of not using any processing tool, or using a tool not certified by SAP for integration, were discounted from consideration. 

Option A: Use Readsoft OCR and Process Director for Invoice Management

Use one of the tools already recommended by SAP and (where possible) approved or validated for working with S/4 HANA Cloud

Note that currently only OpenText is validated as the preferred tool for S/4 HANA Cloud - but the actual selection of Readsoft or OpenText can be handled at Detailed Design Continue the use of ReadSoft OCR and ReadSoft Process Director, but integrate these with S/4HANA. Most probably this would require a re-implementation of ReadSoft Process Director due to the different configuration and processes inside the S/4HANA system as compared to Syensqo's existing ECC-based implementation. 

Option B: Use OpenText OCR and VIM for Invoice Management

Use one of the tools already recommended by SAP and (where possible) approved or validated for working with S/4 HANA Cloud

Note that currently only OpenText is validated as the preferred tool for S/4 HANA Cloud - but the actual selection of Readsoft or OpenText can be handled at Detailed Design Implement OpenText VIM for the invoice processing functionality inside S/4HANA, and supplement this by implementation of the OpenText OCR component to parse incoming PDF invoices. This would cause the ReadSoft solution to be discontinued in parallel with the ECC system where it is implemented today.
