Check an invoice against the order confirmation.

Agreement between documents has a scope.

Check the customer PO number, confirmation reference, parties and relevant amendments before comparing line items. Record the original quantities, units, currencies and prices from each source.

This comparison checks consistency between confirmation and invoice. It does not prove delivery, authorize payment or establish which source is correct. If receipt matters to your process, review the receiving evidence separately.

The amounts below come from Recon’s synthetic hospitality-linen sample. The findings are prepared examples, not live AI results or evidence of customer savings.

Trace the invoice price mismatch to its line.

Confirmation WL-3106 lists 300 NP-5050 napkins at $2.40 per piece. Invoice WL-8814 lists the same item and quantity at $2.60 per piece.

($2.60 − $2.40) × 300 = $60.00. Each document’s line arithmetic is internally consistent. The difference is between the documents.

Look for a documented price amendment. The sample contains none, so the difference stays open. Calling it an overcharge would go beyond the evidence provided.

Two invoice rows can belong to one confirmed line.

For DC-220 duvet covers, the confirmation records 120 pieces and $2,160. The invoice separates them into line 10A with 40 pieces and $720, and line 10B with 80 pieces and $1,440.

In this sample, the record relationship is assumed confirmed. The item reference, unit and currency agree: 40 + 80 = 120 pieces, and the printed amounts sum to $2,160.

Keep both source rows with the result. Do not aggregate lines merely because their descriptions look similar, and do not infer that agreement proves the goods arrived.

Do not assign the whole total difference to freight.

The confirmation total is $3,480. The invoice total is $3,625. The $145 difference consists of the separate $60 napkin price change and $85 freight charge.

The confirmation says freight is not specified. That does not mean an agreed zero charge. Record the new charge, check for approval and retain the source terms.

• Item price: inspect the confirmed and invoiced price, plus any amendment.
• Freight: inspect the stated charge and any separately agreed delivery terms.
• Total: explain how the components contribute to the difference without counting them twice.

Keep the finding and decision together.

For each open item, record both originals, source pages, the question to resolve, the reviewer and the next action. An accepted difference needs its reason and supporting evidence; acceptance does not erase the original difference.

If a revised document arrives, retain the previous version and review the affected findings again. Do not assume a changed invoice settles an unrelated missing specification.

Use the manual reconciliation checklist, or inspect the full worked example and original PDFs. For an earlier check, start with purchase order vs. order confirmation.
