Invoice verification
software with AI.
From configuration to automation in minutes, format-agnostic and entirely template-free.
Your team only reviews exceptions: the AI reads every incoming invoice, whether PDF, scan or e-invoice (ZUGFeRD, XRechnung), validates it against §14 UStG and your own verification rules, and auto-approves uncritical documents. No templates, no lengthy implementation project.
No obligation · 30 minutes · with your real invoices
Since 1 January 2025, every company in Germany must be able to receive B2B e-invoices. Automating that intake check means you are prepared – not just able to receive.

Understanding and choosing AI invoice verification software
What it is, which features really matter and who it pays off for.
What is digital invoice verification?
Digital invoice verification is the software-based control of incoming invoices. Instead of capturing and matching every invoice by hand, an AI reads the data, checks the mandatory fields, tax and totals, matches against purchase order and goods receipt, and approves unambiguous cases automatically.
Unlike classic OCR, an AI solution needs no per-supplier templates: it understands every layout, including e-invoices such as XRechnung and ZUGFeRD, and learns from every correction.
What is invoice verification software with AI?
Invoice verification software with AI is a program that automatically reads incoming invoices, checks them against mandatory fields, tax and the purchase order, and approves them, template-free and documented in a GoBD-compliant way.
In short: the AI reads, checks and approves, without templates and in seconds instead of minutes.
What features should AI invoice verification software have?
These seven criteria separate real AI from dressed-up OCR:
- Template freedomunderstands new layouts without training, no per-supplier template maintenance
- Full format coveragePDF, paper scan, ZUGFeRD and XRechnung alike
- Real verification depthmandatory fields, tax logic, arithmetic totals and 3-way match, not just text recognition
- Learning abilityimproves with every correction, no re-implementation
- ERP integrationSAP, DATEV and more via connector or API
- Fraud and duplicate protectionIBAN and anomaly checks before payment
- Complianceaudit-proof, GoBD-compliant trail, GDPR and the EU AI Act
Who is AI invoice verification for?
AI-based invoice verification software has the biggest impact for:
- companies with high document volume (hundreds to thousands of invoices per month)
- many different suppliers and invoice formats
- decentralized approvals across sites and departments
- regulated industries with strict compliance and audit requirements
Six building blocks. One verification run.
From AI extraction to approval: each capability is strong on its own and feeds seamlessly into the next.
AI extraction
PDF, paper scan, e-invoice (ZUGFeRD, XRechnung), email attachment: everything is recognized and ingested automatically, without you maintaining templates.
- E-invoices (ZUGFeRD & XRechnung) processed natively
- Paper scans and photo receipts without a template
- Intake via email inbox, API or upload
- No template mapping, no pre-configuration
Fits into your system landscape.
Invoices from every intake channel, handed over to your ERP, DMS or BI in structured form. Format-agnostic, no templates, no media discontinuity.
- PDF, scan, e-invoice (ZUGFeRD, XRechnung), EDI & PEPPOL as intake
- SAP, DATEV, Dynamics 365 & other ERPs as targets
- REST API & webhooks for custom connections

RIBDigital invoice verification in five steps.
From intake to approval, our software replaces the manual review of every incoming invoice with a continuous, traceable process: capture, verify formally and substantively, approve.
- 01
Invoice intake & AI extraction
Whether PDF, paper scan or e-invoice (ZUGFeRD, XRechnung): every incoming invoice is captured automatically and read by AI, entirely without templates and even on a first-seen layout.
- 02
Formal verification against §14 UStG
Mandatory fields, tax statement and arithmetic totals are verified. If a field is missing or the tax logic is off, the invoice gets flagged instead of waved through.
- 03
Substantive checks & 3-way match
The invoice is matched against rates, purchase order and goods receipt: quantities, prices and terms. Deviations are escalated deliberately, not ignored.
- 04
Duplicate & fraud screening
Duplicate submissions, deviating IBANs and unusual patterns are detected before payment goes out, automatically on every invoice.
- 05
Invoice approval & handover to the ERP
Approvals run role-based under dual control; approved documents go to SAP, DATEV & co. in GoBD-compliant form, up to 80% processed touch-free.
This turns manual, error-prone invoice verification into a digital, automated process: shorter processing times, fewer errors and a complete, GoBD-compliant audit trail, while your team only handles exceptions instead of checking every invoice by hand.
Manual invoice verification costs working days. Our software gives them back.
Drag the slider to your invoice volume. The time gain is illustrative and based on typical handling times, not on your specific costs.

Individual features exist everywhere. The combination does not.
Even strong enterprise tools like SAP- or xSuite-based AP cover a lot. ADVISORI combines everything modern invoice validation needs – in one tool:
Plain XRechnung format validation, by contrast, is freely available (open-source KoSIT validator) – and therefore not a differentiator.
As of June 2026. Comparison by vendor category based on publicly documented features; individual vendors within a category may differ, and some statements are vendor-documented rather than independently audited. "Chat" refers to a conversational rule/workflow builder – conversational assistants (copilots for queries) do exist at several vendors. Brand names are examples and property of their respective owners. Not a ranking of individual products.
This combination only exists at ADVISORI – let’s talk through your use case.
