AI Agent for Purchase Order Exceptions
Short answer
When a confirmed purchase order changes, an AI agent sets the supplier's old and new dates beside the linked production order and the date promised to the customer in correspondence, points out gaps and passes the case to the buyer for decision. The buyer decides. The agent costs from €3,000 net at Syntalith and, with 150 purchase order changes a month at 25 minutes each, pays back in 2.0 months.

What the decision-maker should receive
A supplier moves the date of one line on a confirmed purchase order. In the system, the planner has a production order that depends on this delivery and, according to the record, needs the part only after the new date. Looking only at the system, the change seems harmless. The thread with the customer, however, shows that the salesperson promised earlier shipment of the finished product, and that date never reached the system.
The agent shows the supplier's old and new promise, the linked order line, the production order, the date for the customer found in the correspondence, and the items that need confirming. The buyer decides whether to negotiate with the supplier or warn the salesperson. Sending the same confirmation again does not create a second case, and a later version from the supplier replaces the earlier assessment.
- A change the agent has not seen before
- A deliberately incomplete set of evidence, for example without the customer thread
- The same confirmation sent again
- A later version of the confirmation from the supplier
If the agent misses a known record, assigns a message to the wrong line or merges two versions, the rollout waits until we establish the cause.
What it costs and when it pays back
- Today
- 150 purchase order changes × 25 min = 62.5 h (€2,181)
- With the system, a person checks the output in 30% of the time
- €654
- Model, 3 calls per case, Claude Sonnet 5.5
- €9
- Cost of one case
- €14.54 today, €4.42 with the system
- Saving
- €1,518 a month
Payback of €3,000
2.0 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: 8,000 input and 600 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 bigger cost than the buyer's hours is a change nobody assessed. A late part moves production, and the customer learns about the delay on the planned shipping day. So the trial also counts the changes where the agent found a promise to the customer that the system did not show.
First check your current purchasing system
Some systems have their own workflow for changes after an order is confirmed, which groups the changes for approval. If the system shows the changed confirmation, the dependent requirement and the next approval step, its workflow or a rule is enough. An agent makes sense when assessing a change needs information from outside the system: a date promised to the customer in an email, or arrangements with the supplier in a thread.

Where to start
For the first call, prepare an anonymised confirmation before and after the change, the linked requirement record and an example of correspondence about the customer's date. 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 checking 800 supplier invoices by hand
Payback: 1.3 mo.
6 minutes to compare an invoice with the order and the goods receipt 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: €0.0040 per invoice, measured in our invoice coding system (0.004514 USD), at the ECB rate of 1.1205 USD per euro on 22 October 2026.
