How Much Does AI Automation Cost? Prices, Cost Components and a Worked Example
How much does AI automation really cost? Real prices for AI agents, every cost component, a worked ROI example and funding options in Bavaria, Germany.
AI invoice processing
Supplier invoices,booked automatically.
An AI agent reads every incoming invoice, matches it against the purchase order and delivery note, and suggests the account coding. Your team only approves, then everything goes to DATEV or your accounting system. It works with PDF, scans, XRechnung and ZUGFeRD.
Example calculation
One supplier invoice,handled twice.
The times are typical reference values, not measurements from a client project. In the pilot we measure your real numbers.

How it works
From the inboxto the books.
The agent handles the supplier invoice from start to finish. You decide where a person approves.
1
Receive
Invoices arrive by email, upload, scan or supplier portal. The agent collects them in one place and spots duplicates.
2
Extract
Supplier, invoice number, date, line items, amounts, tax rates and bank details are captured. For XRechnung and ZUGFeRD straight from the structured data.
3
Match
The invoice is compared with the purchase order and delivery note. If quantity, price and terms fit, it moves on. Discrepancies are flagged.
4
Suggest coding
From your past bookings the agent learns the general ledger account, cost centre and tax code, and suggests them.
5
Approve
The person in charge sees invoice, match and suggestion at a glance and approves with one click, for example in Teams or Outlook.
6
Hand over
Document and booking data go to DATEV, SAP or your accounting system. The invoice is filed and every step is logged.
E-invoicing
Ready for Germany'se-invoicing mandate.
Since 1 January 2025, every business in Germany must be able to receive e-invoices in B2B trade. An e-invoice is a structured format such as XRechnung or ZUGFeRD (version 2.0.1 or later, excluding the MINIMUM and BASIC-WL profiles). A plain PDF does not count.
For issuing invoices, transition periods apply:
- Until 31 December 2026, all businesses may still send paper or PDF invoices.
- Until 31 December 2027, this only applies to businesses with a total turnover of no more than €800,000 in the previous year.
- From 1 January 2028, all domestic B2B invoices must be e-invoices. Exceptions exist, for example for small invoices up to €250.
Source: German Federal Ministry of Finance FAQ on e-invoicing and the BMF letter of 15 October 2025 (both in German). Your tax adviser can tell you how this applies to you.
During the transition, PDFs, scans and XML files arrive side by side. That is exactly what the agent is built for: it handles every format in the same workflow and makes XML invoices readable for approval. For other documents such as delivery notes and contracts, see AI document processing.
In detail
What the agent checksin accounts payable.
Three-way match
Invoice, purchase order and delivery note are compared line by line. The agent recognises partial deliveries and credit notes.
Mandatory fields and tax
If the VAT ID is missing, the tax rate is wrong or the invoice is a duplicate, it does not move on. It goes to you.
Coding that learns
Suggestions for account, cost centre and tax code are based on your own bookings. Corrections feed into the next suggestions.
Early payment discounts
Payment terms and discount deadlines are captured. Invoices with a tight deadline go to the top of the approval list.
Approval on your terms
Up to an amount, per cost centre or per supplier: you set who approves and what may pass without a click.
Part of your automation
Invoice processing is often the first workflow. More workflows can be added on the same foundation.

Frequently asked questions
What does AI invoice processing cost?
A pilot for your incoming invoices starts at €2,500, ongoing operation at €250 a month. We give you the exact price after the intro call, once we know volumes and systems. All prices net, plus VAT.
Does it work with DATEV?
Yes. The agent hands documents and booking suggestions to DATEV so your tax adviser can keep working as usual. The same goes for SAP and other accounting systems with an interface.
Can the agent process XRechnung and ZUGFeRD?
Yes. For e-invoices it takes over the structured data directly and creates a readable view for approval. PDF and paper invoices are read with AI. All formats run through the same workflow.
What if the agent misreads something or the invoice does not match?
Uncertain fields and differences from the purchase order are flagged and go to your team with all documents. Only what passes the checks or has been approved by a person gets booked. Every step is logged.
Is it GDPR-compliant?
Yes. We implement in line with GDPR and agree together which data the agent may see and where it is processed. More in our article on AI and data protection.
From how many invoices does it pay off?
It depends on the effort per document. As an example calculation: at 40 invoices a week and 15 minutes of manual work each, you save about nine hours a week. In the intro call we run the numbers with your figures.
