AI agents for audit evidence collection
Short answer
An AI agent for collecting audit evidence links each auditor request with the files and correspondence received, shows what is still missing and writes a specific question to the person who has the material. The audit scope and the assessment of evidence stay with people. The agent costs from €3,000 net at Syntalith and, with 200 audit requests a month at 15 minutes each, pays back in 2.5 months.

payback of a €3,000 agent with 200 audit requests a month: €1,745 of work today, €529 with checking and the model. Scenario.
52.5%
According to Eurostat (2025), 52.5% of EU enterprises that considered AI and did not use it named a lack of clarity about the legal consequences.

A training invitation does not show who attended
The list of materials for an internal audit includes a request for the attendance record of a named team at a completed training session. The organiser added the calendar invitation to the folder. The file is there, so in the spreadsheet the request looks done, and the coordinator only sees on opening it that the invitation does not show who came.
The agent assigns the file to the request and writes to the coordinator: an invitation was received, and checking attendance needs a record of participation. It proposes a message to the organiser: „The folder holds the invitation to the training. The request concerns the attendance record of the named team. Please send material showing who took part, or tell us where we can find it”. When the record arrives, the agent attaches it to the same request, and the coordinator checks that it concerns the right team and meeting.
- 01Requestan item from the list agreed with the auditor
- 02Materiala file or email assigned to the request, also from a separate thread
- 03Assessmentwhether the material answers the request or only relates to it
- 04Questiona specific message to the person who has the missing material
- 05Reviewthe coordinator checks the document before sharing it with the auditor
The starting point is the list agreed with the auditor. When a request is unclear, the agent describes the doubt, and it does not widen the audit scope with further requirements.
What it costs and when it pays back
- Today
- 200 audit requests × 15 min = 50 h (€1,745)
- With the system, a person checks the output in 30% of the time
- €524
- Model, 2 calls per case, Claude Sonnet 5.5
- €5
- Cost of one case
- €8.73 today, €2.64 with the system
- Saving
- €1,216 a month
Payback of €3,000
2.5 months
The volume, the time and the checking share are the scenario's assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat. Model: 5,000 input and 400 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026.
The count covers the work around a case: searching, reading, writing and passing things on. What remains is the time to check the output, 30% of today's work in the scenario. Before the quote we measure both times on 20 to 100 cases the team has already handled, in a €0 test that takes 5 working days.
A ready-made platform may already check for gaps
The Vanta Information Request List lets you assign people to requests, collect materials and track their status. With a small set of requests, a shared list with a responsible person and a link to the document is enough. An agent makes sense when materials land in different inboxes and folders, and the coordinator keeps judging whether a file answers the request.

Where to start
The first scope covers one package of audit requests. On a finished audit we check whether the prepared question would have let the organiser find the needed material straight away. We build this as part of AI agents. For the free process review, a description of one case from recent weeks and the tools it ran through is enough. You do not need to send confidential documents, and you get a written plan within 2 working days.

a month for matching 1,000 documents to cases by hand
Payback: 1.5 mo.
4 minutes per document matched to a case and checking in 15% of the old time are our assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Model cost: reading a document in our case-file system (about €0.0002) plus matching it to the case and a note on what is missing (Claude Sonnet 5.5, about 2,000 + 300 tokens), at the ECB rate of 1.1205 USD per euro on 22 October 2026.
