Your accountant is missing an invoice. Where to look and how to ask for it

First clarify exactly what is missing

‘The phone invoice is missing’ can mean several things: the accountant has no file, the invoice names the wrong buyer, or the file covers the previous period. Compare the request with what you already handed over before searching again. The right attachment may already be in an earlier email.

If you have several companies, add the buyer to each missing item. The same supplier may invoice you personally and a company. Finding any invoice from that supplier does not mean the problem is solved. You need the document for the specific purchase and correct company.

If a reminder is unclear, briefly ask how the accountant identified the missing document. Payment date and amount, supplier name or order number are a much better starting point than downloading every file from the past month.

Choose the most likely route

For a recurring service, start where you found the previous document. For a one-off purchase, the order confirmation and who arranged the purchase help. For services prepaid by card, check the customer account's billing section. A bank payment is a useful clue, but may not reveal where the document is.

Suppose the missing invoice is for a rental car on a business trip. A colleague paid and received the booking confirmation. Ask: ‘Which rental company did you use on 12 August, and can you forward the final invoice for that rental?’ If they send only the booking, use its supplier and reservation number to request the final invoice. A booking confirmation does not tell you whether the final invoice has been issued.

If the portal only shows older documents or the link does not work, make a note and contact the supplier. Repeating the same search will not help at that point.

Send the supplier details that identify the purchase

“Please send me the invoice” often prompts more questions. The supplier needs to identify the customer and specific order or service. Order number, approximate date, company given at purchase and customer-account email help. Do not include a password or complete payment-card details.

Adapt the following text to your situation. If the invoice exists, you are asking for a copy. If the buyer needs correcting, say so separately and let the supplier explain the available process. Do not edit the original PDF yourself to make it look as though it was issued to a different company.

Your accountant needs to know what you are already resolving

Do not hold back all other records while waiting for the last missing invoice. Unless agreed otherwise, hand over prepared documents and explicitly identify the outstanding item. For example: “The car rental invoice from 12 August is missing. I asked the rental company for a copy today and will send it as a supplement.”

For several missing documents, keep a short list of what you need, who you contacted, and what you are waiting for. When your accountant follows up, you can pick up where you left off.

Finding the file is not the end

When the invoice arrives, open it and check the business, purchase, and any corrections. Send it as an addition to the earlier conversation so your accountant can immediately see which missing item you resolved.

If the same supplier keeps causing a search, fix the recurring cause: the invoice delivery address, buyer details on the account, or the place where you download invoices. Finding one file closes this month’s gap; recording the correct delivery or download route avoids repeating the search next month.
