How NXT AP works – The core stack
SAP-native execution with governed cloud intelligence. SAP remains the system of record and the execution environment. The NXT AI Harness governs every authorised interaction between NXT AP and external AI or cloud services.
NXT AP achieves this by combining three key layers:
Layer - SAP
Responsibility - Current master and transaction data, financial documents, authorisations and standard process execution.
Layer - NXT AP
Responsibility - Autonomous process orchestration and Accounts Payable domain logic.
Layer - NXT AI Harness
Responsibility - Approved services, data boundaries, NXT Skills, validation, confidence controls, audit and change governance.
Layer - Connected services
Responsibility - Specialised document intelligence, LLM, mailbox and e-invoice connectivity functions.
Layer - NXT EDGE
Responsibility - Authorised human action when a process exception requires judgement, validation or approval.
Why NXT AP is the right choice?
Purpose-Built for SAP — NXT AP is designed around SAP FI and MM processes. It does not transfer responsibility for Accounts Payable processing to a separate workflow platform.
Current data, evaluated in real time — Every invoice is processed using current SAP master data, purchase orders, goods receipts, accounting information and configuration. Decisions do not depend on periodically replicated data.
Complete process automation — NXT AP coordinates invoice retrieval, capture, validation, matching, exception handling, approval and posting as one continuous process.
AI within governed processes — Specialised AI services perform defined interpretation and reasoning tasks. The NXT AI Harness controls access, data use, validation and audit before results influence the SAP process.
One process for every invoice source — PDFs, scans, hybrid invoices and structured e-invoices enter the same governed Accounts Payable process.
SAP remains the system of record — SAP remains the authoritative environment for financial data, document processing, authorisations and posting.
What is not required - NXT AP does not require a separate Accounts Payable database containing replicated versions of SAP supplier, purchase-order and goods-receipt data. This reduces data duplication, synchronisation delays, conflicting business logic, additional reconciliation and dependence on middleware-based batch processes.

NXT Document Analyzer — compliant processing across invoice and document formats
NXT Document Analyzer is the evolution of NXT PDF Analyzer. Its scope extends beyond analysing conventional PDFs and embedded XML. It identifies, extracts and validates invoice information across multiple document and electronic-invoice formats before transferring the result into NXT AP.
NXT Document Analyzer supports:
-Conventional PDF invoices.
-Hybrid invoices containing embedded structured XML.
-XRechnung.
-Factur-X.
-Digitally signed Italian P7M documents.
-PDFs containing multiple invoices or supporting documents.
More than document extraction
The Analyzer identifies the relevant data source within each document, validates structured information and preserves the relationship between structured data, the visual document, signatures and supporting information. This gives NXT AP a reliable and compliant invoice representation regardless of the original format.

Agentic Finance Automation
NXT combines SAP-native process execution with specialised AI agents, intelligent document processing and global e-invoice connectivity. At the centre of the product family is NXT AP: the autonomous Accounts Payable solution for SAP. It processes supplier invoices from receipt to posting using current SAP data, standard SAP transactions and embedded AI and cloud services governed through the NXT AI Harness.
What are AI agents ?
A Vertical AI Agent is an AI-powered system tailored for a specific business domain—in this case, Accounts Payable. Unlike horizontal AI platforms that offer general-purpose capabilities, NXT AP is deeply embedded into SAP and specialized for processing supplier invoices using native SAP FI/MM processes enhanced by AI.
NXT AP’s vertical integration includes:
-
SAP-native document parking, matching, and posting.
-
Real-time interaction with SAP data and business rules.
-
AI-based reasoning in predefined domains like compliance, OCR-result validation, line-item coding proposal (Non-PO), payment terms optimization, and more.
NXT AI Harness
NXT AI Harness — enterprise guardrails for AI-powered finance processes
NXT AP is not trusted simply because it uses AI. It is trusted because the use of AI is governed, traceable and embedded in controlled SAP processes.
The NXT AI Harness is the governance and integration framework through which NXT AP uses AI and connected cloud services. It determines which service may be used for a task, which authorised data may be provided, how an output is validated before it influences the SAP process, whether processing may continue autonomously or requires human review, and what information is retained for audit and traceability.
