What to include in an invoice discrepancy report

An invoice discrepancy report should let another person find the source, reproduce the difference and understand what remains to be decided. Include the documents and revisions reviewed, original values, calculation, review status and supporting record for each decision.

A list headed “invoice errors” can overstate the result. A changed price may have been accepted, a missing item may be billed later, and two invoice rows may belong to one PO line. Describe the document difference first, then record the explanation or next action.

Identify the scope before listing findings

Record the supplier, buyer entity, order reference, invoice identifier and currency. List every included file with its revision and date. State the comparison basis, review date and any missing records.

For the site’s fictional sample documents, the scope might read:

Compare PO-1042 revision 1 with INV-8821, both in USD before tax. Use the PO as the exercise baseline. No supplier confirmation, buyer amendment, receiving record or payment history is included in this review. Receipt, commercial acceptance and payment status remain unverified.

That note limits what “reviewed” means. Someone reading only the report should not have to guess whether the reviewer checked goods receipt or searched for earlier payments.

If several PO versions exist, first complete the baseline and revision check. Add the selected revision and its supporting approval reference to the report.

Give each difference a source and a calculation

The sample PO lists AX-100 at $4.00 for 100 each. The invoice lists the same quantity at $4.20. A useful finding records both values and the source location:

Report field	Filled example
Finding	D-01: AX-100 unit price difference
PO source	PO-1042.pdf, page 1, printed line 10, AX-100
Invoice source	INV-8821.pdf, page 1, printed line 2, AX-100
Original PO value	100 each at USD 4.00; line amount USD 400.00
Original invoice value	100 each at USD 4.20; line amount USD 420.00
Calculation	100 × (4.20 − 4.00) = +USD 20.00
Status	Open; price acceptance not established
Next action	Purchasing reviewer to obtain the applicable price approval or supplier correction

Use the printed line label where one exists. Otherwise identify the page, table and item text closely enough to locate the row. A link to a whole PDF is less helpful when it contains dozens of similar items.

Explain why the total differs

The sample invoice is $128.00 lower than the PO, but it contains positive and negative differences:

Item	Amount difference, invoice minus PO	Review question
AX-100	+$20.00	Was the price increase accepted?
BX-200	−$20.00	What explains the lower price?
CX-300	$0.00 after documented case-to-each conversion	Is the stated pack size applicable?
DX-400	$0.00 after grouping the two invoice rows	Do both rows refer to this ordered item?
EX-500	−$180.00; absent from this invoice	Is it billed separately or outside this invoice’s scope?
FX-600	+$24.00	Were the additional two units authorized and received?
Freight	+$28.00	What supports this charge when the PO says freight is included?
Total	−$128.00	$1,512.00 invoice minus $1,640.00 PO

The +$72.00 of positive differences is an amount to investigate, not a confirmed recovery. The missing $180.00 item is not a credit. Keep those descriptions attached when you share the figures. The overcharge-checking guide explains the same calculation in more detail.

Separate corrections from decisions

If extraction read $4.20 as $42.00, correct the extracted value with a reference to the original invoice. Preserve what changed and rerun the affected comparison. That fixes a reading error.

If $4.20 was read correctly and the buyer accepts the increase, record the decision and approval evidence while retaining the original $4.00, $4.20 and $20.00 difference. If the buyer disputes it, record the dispute and follow-up. A decision does not change what the supplier printed.

For a handoff, include who owns the next action and any agreed follow-up date. An unresolved item should remain visible even if the rest of the review is complete. Do not insert a reviewer’s name or an approval date until someone has actually made that decision.

Share a report someone else can finish

Before sending the report, verify that its file references point to the versions you reviewed. Include the relevant source documents through your approved sharing process. Keep later corrections as new versions so the recipient can tell which report they are using.

For a supplier query, take the item identifier, both values and the calculation from the report, then ask for the record that would resolve the difference. The supplier email templates provide wording for price, quantity and extra-charge questions.

LineRecon supports reviewing source evidence and exporting Excel or PDF reports. A downloaded report reflects the selected result and review state; subsequent decisions need a new export. Verify the contents before using it for a purchasing or payment decision.

Common questions

Should accepted differences disappear from the report?

Keep the amount difference and its explanation. Otherwise a later reviewer cannot distinguish a document that matched originally from one whose difference was accepted.

Can I call the report an audit certificate?

Describe it as a document comparison and review record. The worksheet does not establish an independent audit, certification or approval to pay.

What if some files or pages could not be read?

List them in the scope and say which checks remain incomplete. A report covering the readable files cannot establish that the entire order is consistent.
