Automating supplier rebate reconciliation
Short answer
Automated reconciliation of retrospective rebates counts, by approved rules, how much rebate is due for the period, compares the result with the supplier's statement and shows the difference with the source documents. The finance team approves the result. At Syntalith the automation costs from €3,000 net, and with 30 rebate settlements a month at 120 minutes each it pays back in 2.1 months.

Supplier rebate reconciliation: a return after the period closes
A supplier contract grants a rebate on purchases of named product lines in a quarter. After the period closes, the supplier sends a statement, and its value does not match the wholesaler's calculation. Comparing two totals will not explain the difference. A return of goods after the period closed may have changed the qualifying base, the statement may have covered a different date range, and one invoice may have landed in the wrong line.
The automation counts by rules finance has approved: the period, the qualifying items and the basis of calculation. An AI model can help read the terms from the contract or the supplier's statement in PDF, and code does the calculation. The user sees the expected value, the value the supplier claims and the disputed value, with the documents the difference comes from. Before the start, finance agrees with the contract owner how to treat returns and corrections after the period closes.
- A closed period for which finance knows the correct result
- A return of goods after the period closed
- A source record corrected after an earlier calculation
- The difference shown with the documents it comes from
If the test does not reproduce the agreed result or does not show the source of the difference, we fix the rule or the import first. A result with no source for the difference does not help in a conversation with the supplier.
What automated rebate reconciliation costs and when it pays back
- Today
- 30 rebate settlements × 120 min = 60 h (€2,094)
- With the system, a person checks the output in 30% of the time
- €628
- Model, 2 calls per case, Claude Sonnet 5.5

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: 20,000 input tokens and 1,500 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026. The time covers collecting purchases, returns and the supplier's statement and explaining the difference for one contract.
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.
Use your current system first
If your purchasing system has a rebate module, start by configuring it and importing the supplier statements. With stable rules and a few statements a quarter, a well-controlled spreadsheet that finance can check is enough. An automation makes sense when there are many contracts, each with different periods and thresholds, and statements arrive in different formats. Rebates concern the contract terms, and the margin on an order is covered in the article on order-level margin reports.

Where to start
The first scope covers one supplier's contracts and one closed period for which finance knows the correct result. 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.

a month for preparing 20 reports
Payback: 1.7 mo.
3 hours to collect the data and prepare a report 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: checking the commentary in our reporting system (about €0.0002) plus compiling the data (Claude Sonnet 5.5, about 30,000 + 2,000 tokens), at the ECB rate of 1.1205 USD per euro on 22 October 2026.
