← All guidesWhen an invoice comes back

Queried invoice? Start here.

Start with the actual question. A query is a request to review something—not a reason to guess at a new invoice.

  1. Find out what needs checking

    Read the message carefully. If the reason is unclear, ask the payment contact which invoice and line item they mean.

  2. Compare with your records

    Check the queried details against the support delivered, the agreed arrangements and your original invoice.

  3. Correct only what needs correcting

    If there is an error, clearly identify the corrected invoice and keep a record of the change. Confirm how the recipient wants it resubmitted to avoid duplicates.

  4. Keep a clear follow-up trail

    Save the query, your response and any revised document securely. Agree on the next step; do not assume resubmission means payment is approved.
