Reconcile a supplier statement

Every month a supplier sends a statement that doesn't agree with your ledger. Before you call them, you want to know exactly which items differ, and why.

Claude can compare short lists, but long statements need a tool. The Supplier Statement Check server matches the supplier's statement against your open items, lists every difference with its source values, and exports a CSV. It runs as a local install only and needs structured data, not PDF scans.

Without a tool, and with the tool

Without a tool

Claude can compare two short lists you paste and find some differences. With 40 or more open items it can lose track, it doesn't keep the result, and it can't give you a CSV of the differences.

With Supplier Statement Check

Supplier Statement Check compares the supplier's statement with your open items at a date, lists each difference with the source values, saves the report and exports CSV. It runs only as a local install from a source checkout. It doesn't read PDFs or post payments.

Reconcile a supplier statement

You

Here is the statement from Northern Paper Co at 31 October (28 lines) and our open items for them. What doesn't agree?

  1. supplier_statement_check Compares the two sides and lists every difference
  2. report_page Shows the detail for each mismatched item
Result

A list of items only on the supplier side, items only on yours, and amount differences, with the values behind each.

Example · Priya Shah, AP clerk at a food wholesaler in Manchester, UK

Month-end statement from a key supplier

You

Here is the October statement from Fresh Fields Ltd (42 open items) and our ledger for them (40 items), both as at 31 Oct. Check them and tell me what doesn't agree.

  1. supplier_statement_check Groups items by entity, supplier, currency, type and reference, and lists each difference
  2. report_page Pages through the discrepancy section with the original rows
Result

38 matches, 2 invoices only on the statement (GBP 1,240.00 and GBP 318.50), and 1 amount mismatch on INV-7731: GBP 960.00 on the statement against GBP 690.00 in the ledger.

Keep evidence for a supplier dispute

You

Compare the Stal-Pol statement and our ledger at 30 September, save the report, and give me a CSV of the differences for their accountant.

  1. supplier_statement_check Runs the exact-reference check and saves the report
  2. report_export_csv Writes one CSV row per original statement and ledger item
Result

A saved report and a CSV that shows credit note KN/09/114 for 4,500.00 PLN on the statement with no match in the ledger, plus two date mismatches.

Common mistakes with this job

  • Comparing only balances, so you know the gap but not which invoice causes it.
  • Ignoring timing: a payment sent on the 30th that the supplier books on the 2nd.
  • Paying the statement balance without checking it.

Questions

Can I do this in Claude?
Claude can compare short lists, but long statements need a tool. The Supplier Statement Check server matches the supplier's statement against your open items, lists every difference with its source values, and exports a CSV. It runs as a local install only and needs structured data, not PDF scans.
Does it read the PDF statement?
No. You supply the open items as structured records. There's no OCR, no ERP link and no currency conversion.
How does it match items?
Only by exact entity, supplier, currency, document type and reference. It doesn't guess. A reference that appears twice on one side is marked ambiguous.
What does Pro add?
Only more saved reports. Free keeps 3, and deleting one frees its slot.
