AI in HR: working time records and documentation

Short answer

AI in HR reads working time information from managers' messages, flags gaps such as a date or an employee ID, and prepares a proposed correction of the time records. HR approves the correction, and the history keeps the original entry. At Syntalith the automation costs from €3,000 net, and with 600 time record corrections a month at 6 minutes each it pays back in 2.1 months.

Statistics

HR and AI: statistics 2026

2.1 mo.

payback of a €3,000 automation at 600 time record corrections a month: €2,094 of work today, €632 with checking and the model. Scenario.

Figures checked: 22 October 2026

A manager's message is no complete finding

A manager writes: „On Tuesday Anna stayed two hours longer.” The message gives no date and no employee ID, and there are two people called Anna in the team. An automation that fills in the date from the day it runs and picks the first Anna on the list will record overtime for the wrong person on a Tuesday from the wrong week.

The proposed workflow keeps the text of the message and flags the missing information: the date and the person. An HR employee clarifies them with the manager and only then prepares the correction. In Poland, Article 149 of the Labour Code links working time records to the correct calculation of pay and other benefits, and Article 94 concerns paying wages and keeping employee documentation. We do not calculate overtime or allowances here: the rules depend on the employee's situation and HR sets them.

What to check in the test
  • Two fictional employees with the same first name
  • A message with no date
  • A correction after the previous summary was accepted
  • The same file sent again, and access by a person outside the team

A correction leaves a readable history: who gave the clarification, the field changed and the version passed to payroll. Access to information is separate from approving a correction, because a manager may need the status of a case without the full documentation of another person.

What automated working time corrections cost and when they pay back

Scenario: 600 time record corrections a month
Today
600 time record corrections × 6 min = 60 h (€2,094)
With the system, a person checks the output in 30% of the time
€628
Model, 1 call per case, Claude Sonnet 5.5

Cost of one case
€3.49 today, €1.05 with the system
Saving
€1,462 a month

Payback of €3,000

2.1 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: 2,000 input tokens and 300 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 each case: searching, reading, writing and handing over. What remains is the time to check the result, 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 free test that takes 5 working days.

A mistake in the records comes back in pay and in documentation the employer keeps for years. So in the test we count minutes and also the reports where the automation rightly stopped at a missing date or person.

Check what your current software can do

If your HR software handles managers' requests and approvals, an extra model is not needed. With a form that holds the date and the employee ID, rules without AI are enough. Reading messages makes sense when managers report changes by email and chat in free form. A copy of employee data in the history of an AI tool needs the same access and retention rules as HR files.

Where to start

The first scope covers the reports of one department, compared with the corrections entered by hand in a closed month. We build this kind of system as part of our AI automations. For the free process review, a description of one case from the last few weeks and the tools it went through is enough. You do not need to send confidential documents, and you receive a written plan within 2 working days.

Worked example · Scenario

How we count the payback: AI in HR and payroll

We run the same count for your department in the free process review.

€2,908

a month for handling 1,000 employee documents by hand

Payback: 1.2 mo.

5 minutes to receive and check an employee document 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 a description of 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.

foap.comcustomer service

foap.com customer service: 95% of replies are sent automatically.

Users from several countries write to foap.com, in several languages. The system reads the entire conversation and the terms of that person, and then sends a response in that person's language. Questions about money and exceptions go to the team with a ready draft, so they have to check and send them.

Data checked on October 21, 2026.

„Is my data safe?”

Yes. You choose where they go: from your company account to the model on your server.

  1. 00Employee's private account

    Customer and company data ends up in an account that the company cannot see or control. There is no data processing agreement, so it is a violation of the GDPR. When an employee leaves, the chat history goes with them.

  2. 01ChatGPT or Claude corporate account

    The provider does not use your data to train models. A copy of the queries remains in his logs for up to 30 days.

  3. 02API with zero retention (ZDR)

    The provider processes the request and does not save anything. It requires his consent, we prepare the application together.

  4. 03Processing in the EU

    Queries are counted and stored in Europe: OpenAI in the EU region, Claude via clouds with the EU region.

  5. 04Model at your place

    The open model runs on your server or in your cloud in the EU. The data does not go outside the company.

What we do with every implementation

  • Confidentiality agreement and data processing agreement before we receive any data.
  • You choose the cases for the prototype and we anonymize them upon request.
  • The data stays in the EU and we delete it after the test.
  • Corporate accounts with an administrator on your side.

When data cannot leave the company

The open model runs on your server or in your cloud in the EU. To choose from:

Qwen
Alibaba
GLM

DeepSeek

We select a model for the task and check it on your cases. We run it, tune it and maintain it.

Do you have a lot of your own data? We will fine-tune the small model.

  1. 1 Your examples
  2. 2 tuning
  3. 3 test on new cases
  4. 4 model at your place

When you have thousands of similar emails, documents or reports, we teach a small open model based on your examples. It works for you, responds quickly and costs less to maintain than a large model. We measure quality on issues that the model has not seen while learning.

Przemysław and Piotr did it in large programming and consulting companies. Artem did it before and does it today at Syntalith. It's about models on your own infrastructure, tuning and quality measurement.

AI implementation

Start with the process that takes the most time each week.

The engineer chooses one process with you and calculates how much it costs today. Then we build a free prototype on 20-100 cases that your team has already handled. We write down the goal and the fixed price in the contract.

Questions

  • Can AI keep working time records?

    It can read managers' reports and prepare a proposed correction. In Poland the employer keeps the records under Article 149 of the Labour Code, and HR approves the correction.

  • What about employee data in an AI tool?

    It needs the same access and retention rules as HR files. The tool's history must not become a second, uncontrolled copy of the files.

  • How much does such an automation cost?

    At Syntalith from €3,000 net. With 600 time record corrections a month at 6 minutes each, the payback is 2.1 months. We agree integrations and maintenance before the quote, and the model costs €4 a month.

Let's talk

Just write, call or choose a date.

We work fast because we hate corporate cotton wool. We don't have salespeople or managers to keep an eye on managers. You talk immediately to engineers who then build your system. We respect each other's time and yours too.

We will accept 3 more companies by the end of the year.
