Invoice Discrepancy Email Templates: Wrong Prices, Quantities and Extra Charges

A useful invoice discrepancy email identifies the invoice, states the values that differ, points to the relevant record and asks for a specific next step. It should help the supplier investigate without guessing which row or agreement you are referring to.

The templates below cover a price difference, extra quantity, added freight, several issues together, a confirmed correction and a follow-up. Replace the bracketed fields and remove claims you have not verified.

Download all six templates as a text file. No email is required.

Include enough evidence for one useful reply

Before sending, confirm the invoice and PO references, the version you checked and the appropriate supplier contact. For each issue, include the item identifier, both values, unit, currency and source location.

When acceptance or receipt is uncertain, ask for the supporting record. Avoid saying a charge is unauthorized or goods were never delivered unless your team has established that conclusion.

These templates help with communication. They do not amend the commercial agreement, set payment terms or determine whether payment may be withheld. Follow your organization’s approval process for those decisions.

1. Unit price differs from the purchase order

Use this when the quantity and unit are comparable but the invoice unit price differs from the referenced order.

Subject: Price query on invoice [invoice number] / PO [PO number]

Hi [supplier contact],

We are reviewing invoice [invoice number] against [PO number and revision].
Could you help us confirm the price for [item code and description]?

Our record: [quantity] [unit] at [currency] [PO unit price] per [unit]
Invoice: [quantity] [unit] at [currency] [invoice unit price] per [unit]
Difference for this line: [currency] [line difference]

The relevant entries are [PO page/line] and [invoice page/line].

Please send the accepted price revision supporting the invoiced rate.
If the rate was entered incorrectly, please advise which corrected
invoice or adjustment document you will issue.

Thank you,

For the fictional sample, AX-100 appears at $4.20 rather than $4.00 for 100 each, a $20.00 difference. That amount is a useful calculation; whether the higher rate was accepted remains a separate question.

Do not use the simple quantity-times-price-difference calculation when units, quantities, discounts or other line components also changed. Explain those components separately.

2. Invoice quantity exceeds the order quantity

Use this when the billed quantity is larger than the quantity in the record you checked. Keep any receiving question explicit.

Subject: Quantity clarification for [item code] on [invoice number]

Hi [supplier contact],

We noted a quantity difference while reviewing [invoice number] against
[PO number and revision].

Item: [item code and description]
PO quantity: [quantity and unit]
Invoice quantity: [quantity and unit]
Invoice unit price: [currency and amount per unit]

Please confirm the basis for the additional [quantity and unit] and
share any related order amendment or delivery reference.

[Optional, only when true: We are also checking the receiving record
with our receiving team.]

Once the records are aligned, please let us know whether a revised
invoice or another supporting document is needed.

Thanks,

In the sample, FX-600 is billed as 12 each against an order for 10 each. The extra two units account for $24.00. The documents alone do not establish whether those units arrived or whether an amendment was accepted.

A repeated SKU is a different issue: it may be a split delivery or two rows that sum to the ordered quantity. Inspect those rows before sending a quantity complaint.

3. An extra freight or handling charge appears

Use this when the invoice adds a charge that your checked agreement appears to include or does not explain. Describe the baseline accurately.

Subject: Clarification of [charge description] on invoice [invoice number]

Hi [supplier contact],

Invoice [invoice number] includes [currency and amount] for
[freight / handling / other charge].

The record we are checking is [PO or agreement reference, revision,
and relevant page/section]. It states [brief, accurate description
of the agreed term].

Please confirm the basis for this charge and send the supporting
agreement or accepted change. If it was added in error, please advise
how you will correct the invoice.

The relevant invoice entry is [page/line].

Thank you,

The sample PO says freight is included, while the invoice adds $28.00. The template asks for the basis rather than inventing a reason such as a rush delivery.

If the PO is silent about freight, write that the record you have does not show the agreed freight amount. Do not replace silence with an assertion that freight was free.

4. Several discrepancies need one consolidated response

Use one message and a compact issue table when several people or documents are involved. Assign identifiers so later replies can refer to the same issues.

Subject: Review questions for [invoice number] / [PO number]

Hi [supplier contact],

We are reviewing [invoice number] against [PO number and revision].
Please help us resolve the following items:

1. [Issue ID]: [item or charge]
   Our record: [value, unit, currency and source]
   Invoice: [value, unit, currency and source]
   Question: [the specific clarification or document needed]

2. [Issue ID]: [item or charge]
   Our record: [value, unit, currency and source]
   Invoice: [value, unit, currency and source]
   Question: [the specific clarification or document needed]

We have attached [relevant extracts or discrepancy schedule].
Please respond against each issue and identify any revised documents
that should replace or supplement the records above.

Please also confirm the appropriate contact for any item that needs
to be handled by a different team.

Thank you,

A completed example for the fictional documents would include:

Issue	Checked record	Invoice	Request
Q-01: AX-100 price	$4.00 per each	$4.20 per each	Provide the accepted rate change or correction
Q-02: FX-600 quantity	10 each	12 each	Provide the amendment and delivery reference
Q-03: freight	Included	$28.00	Explain the agreed basis

These positive differences total $72.00, but that total is not automatically a credit request. Resolve the underlying questions before presenting an amount as confirmed overbilling.

5. Request the correction after the error is confirmed

Use this only after the relevant parties have agreed that the invoice needs correction. Let the supplier identify the appropriate document process rather than assuming whether a replacement invoice or credit document is required.

Subject: Confirmed correction for invoice [invoice number]

Hi [supplier contact],

Thank you for confirming [brief description of the agreed correction]
in [email or other reference, date].

Please issue the appropriate corrected invoice or adjustment document
and reference the original invoice [invoice number]. The agreed change
is [item, quantity, rate or charge correction].

Please identify which document we should use going forward and whether
the original invoice is replaced or remains relevant alongside the
adjustment. This will help us record the change without duplicating it.

Please send the document to [approved billing contact or channel].
We will process it through our normal review and approval workflow.

Thank you,
[name]

When the corrected record arrives, check the changed fields and other amounts. Preserve the original and the correspondence so the next reviewer can understand the sequence.

Avoid deleting the historical invoice simply because a new PDF has been issued. Your accounting team should decide how the documents are recorded under the applicable process.

6. Follow up on an unresolved invoice query

Use this to move the query forward without adding unsupported threats or unilateral changes to payment terms.

Subject: Follow-up: [invoice number] review questions sent [date]

Hi [supplier contact],

We are following up on our [date] email about [invoice number].
The outstanding items are [issue IDs or short descriptions].

To complete our review, we still need [specific clarification,
authorization, delivery reference or corrected document].

Could you confirm who is handling the query and when we can expect
a response? Please let us know if another contact should be included.

We are coordinating the review and any payment-timing questions through
our normal accounts-payable process.

Thank you,
[name]

Where your team has agreed a response date with the supplier, add it accurately. Do not imply that sending this email suspends a contractual deadline.

What should you attach?

Attach the relevant invoice and PO extracts or a discrepancy schedule with their references. Use an approved channel and avoid including unrelated supplier pricing, personal information or bank details.

The matching workbook includes a follow-up log. The sample document pack shows how the item references in this article map to the underlying records.

Before pressing send

Check that the currency and unit appear beside each amount, that the calculation uses comparable values and that the request can be answered. Replace every bracketed field and remove optional statements that are not true.

Where evidence is incomplete, ask a question. “Please provide the accepted revision” is more precise than asserting that no revision exists merely because it is absent from the files you have.

Make the evidence easier to prepare next time

Writing the email is usually straightforward once the facts are organized. The recurring work is finding the right documents, locating each difference and recording its source.
