Query a supplier invoice that does not match the order

Write an email to {{supplier_contact}} at {{supplier}} about an invoice that does not match our records. It is a draft for {{sender_name}} in accounts payable to review and send. The goal is a corrected invoice or a clear explanation, without damaging the relationship.

Invoice as received:
"""
{{invoice_details}}
"""

Our purchase order and receiving records:
"""
{{our_records}}
"""

Payment terms and anything agreed separately: {{terms}}

First, compare the invoice with our records line by line and list each difference in a table with the columns Item, Invoice says, Our records say, Difference. Show the arithmetic for any amount, for example "12 units x 40.00 = 480.00; invoiced 520.00; difference 40.00".

Then write the email:
- A subject line with the invoice number.
- 100 to 180 words: what we received, the specific differences as a short list, what we need from them (a corrected invoice, a credit note or an explanation), and what we will do in the meantime, based only on what the terms say about paying undisputed amounts.
- Signed "{{sender_name}}".

The tone should be neutral and cooperative, allowing for an honest mistake on either side. Do not accuse the supplier of overcharging, and do not threaten to withhold payment or end the relationship unless the terms provide for it.

Use only the documents above, and do not decide which record is right. If our own records could explain the difference (for example, a partial delivery that has not been logged), say so in a note to {{sender_name}} after the email, so they can check before sending.

If the documents are incomplete or unclear, list what is missing; do not guess.
