Automating supplier bank detail change reviews
Short answer
Supplier bank detail change automation takes a request for a new account through the company's rules: independent confirmation by another channel, a decision by an authorised person and the change in the supplier record. A correct-looking account number does not prove the supplier really asked for the change. At Syntalith the automation costs from €3,000 net, and at 100 supplier data changes a month of 30 minutes each it pays back in 2.6 months.

The request and its confirmation need different sources
A supplier sends an email asking to change the bank account for payments. An employee forwards it to finance, and a few days later someone else asks whether the details have been changed and whether anyone called the supplier. The email looks right, with a logo and a signature, but this is exactly the scenario fraudsters use. The FBI recommends confirming payment changes through a channel other than the one the request came by.
The employee follows the company method: a call to a number known from earlier work together, never one taken from the email. They record in the tool how and when they confirmed, and pass the case to the person who decides. The original message stays with the case. A deputy sees the last agreement and the next step. Approving the request and updating the supplier record are separate actions, so the employee closing the case sees a link to the change made in the system.

A model can read from a free-form message what the request is about. Its reading does not prove who the sender is and always has to be compared with the original.
What bank detail change automation costs and when it pays back
- Today
- 100 supplier data changes × 30 min = 50 h (€1,745)
- With the system, a person checks the output in 35% of the time
- €611
- Model, 1 call per case, Claude Sonnet 5.5
- €0.92
- Cost of one case
- €17.45 today, €6.12 with the system
- Saving
- €1,133 a month
Payback of €3,000
2.6 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: 3,000 input tokens 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 stays is the time to check the result, 35% of today's work in this 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.
Here the time count comes second. One transfer to a fraudster's account can cost more than the whole system, so the main measure of the trial is the number of changes that went through without a recorded independent confirmation. The target is zero.
Check the supplier change workflow in your current system
If your finance system has a review of supplier record changes and lets you attach the confirming material, configuring it is enough. Automation makes sense when requests arrive by email or through a portal and the people checking them record the result somewhere else. The company decides who sees the full account details, who confirms and who makes the change. Collecting a supplier's documents more broadly is covered by counterparty verification.

Start with an actual handoff
The first scope covers one request channel and the current way of approving. You provide the rules, the people responsible and the scope of access. We build this kind of system as part of our AI automations. For the free analysis, 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 get a written plan within 2 working days.

How we count the payback: counterparty verification
We run the same count for your process in the free analysis.
€1,047
a month for checking 60 counterparties by hand
Payback: 3.4 mo.
30 minutes to check a counterparty 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. We measured the model cost of the simpler profile, €0.009, in our counterparty profile system, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026. Avoided losses are a scenario: we assume that 1 in 800 counterparties checked is a company that would not have paid, and that the check protects €6,900 on average. In the review we calculate it on your receivables.
