Automating supplier price list checks
Short answer
Automated price list checks compare a supplier's new list with the approved version and the item map before import into your system. The buyer sees a change of unit, minimum quantity or validity date, and lines that need a decision go to a separate queue. At Syntalith the system costs from €3,000 net and at 3,000 lines a month pays back in 2.0 months.

What changes besides the price
A supplier sends a new list. For one product the unit changes from a piece to a pack, and with it the minimum order quantity. The item code looks like the old one. Comparing the amounts alone will mark the line as cheaper, although the buyer will pay more per piece.
That is why the check sets three things side by side: the last approved version of the price list, the new list and the company's map of items and units. If the supplier's document gives the pack size, the team judges the conversion. If it does not, the line waits for clarification.
- The source version and the row number
- The old and the new value of the field
- The kind of change: unit, minimum quantity, price, currency, date
- The decision needed from the employee
- Whether the gap concerns one row or the whole list, for example an unknown currency in the header
The date received does not set the date of validity
The date the file arrived does not say from when the system should apply the new terms. An approved priority rule can handle overlapping dates. When two entries for the same combination of supplier, item, unit, minimum quantity and currency overlap without such a rule, the case goes to the approver. Purchasing systems store prices that depend on the supplier, the item, the minimum quantity, the unit and the dates, as for example Microsoft's documentation on purchase prices describes.
A change log for the buyer
The result of the check is three lists: lines accepted for import, changes waiting for a decision and unresolved cases, for example a missing pack size. The log shows the source version and the changed fields, so a month later it is clear who approved the new unit and on what basis.
Also settle whether a gap concerns one row or the whole list. An unknown currency in the header holds back the assessment of every line, even if each has a correct item code. The scope of a held import should match what really cannot be assessed.
What automated price list checks cost and when they pay back
- Today
- 3,000 lines × 1 min = 50 h (€1,745)
- With the system, a person checks the output in 15% of the time
- €262
- Model, 1 call per case, Claude Sonnet 5.5
- €12
- Cost of one case
- €0.58 today, €0.09 with the system
- Saving
- €1,471 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: 1,200 input tokens and 200 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026.

A model is not needed for every list. If the approved pack size is missing, extracting the text will not add it. According to the European Commission (2026), 90% of companies using AI say that people take the decisions, and that is how it should be with purchase prices.
With every new list, the buyer should see in a few minutes what changed, without comparing thousands of rows by hand. That is the whole value of this automation.
A test on supplier lists
- 01New column layoutThe fields land in the right terms despite the changed file.
- 02Change of unitThe line goes to the queue and stays out of the import.
- 03Date conflictTwo overlapping entries without a priority rule wait for a decision.
- 04False alarmsThe number of flags must not bury the buyer, or they will stop reading them.
If the test lets an unapproved unit through or hides a date conflict, the list is not ready for import. The price list check concerns the terms of future purchases. The later settlement against the contract is described in the article on supplier rebate reconciliation. For the call, prepare an anonymised old and new list, the map of items and units, and the import format.

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.
