The subject helps even months later

The subject should distinguish company, period and type of handover. “Company Alfa — documents for August 2026” is more useful than “invoices” or “new documents”. For a later addition, add “addition”. Label a corrected document as a correction so it is not mistaken for another purchase.

You do not need a complicated abbreviation system. Use the same format that both sides understand. The month identifies the agreed package; it is not itself an accounting decision about which period every document belongs to. For an unusual or late document, give your accountant the facts and let them assess the next step.

When sending a routine package

For a routine handover, say which business the documents belong to, where to find them, and whether anything is missing. If some records are coming through another agreed channel, mention that too. There is no need for a long assurance of completeness.

An attachment count can help checking, but include it only if you have verified it. Saying 18 when there are 16 actual files creates more work than giving no count. For a folder, link directly to the section being handed over and first check that the recipient can open it.

Select the text, copy it into an email and fill in the details in square brackets.

When one invoice is still missing

Identify the missing document so your accountant recognises it. “Something else is coming from suppliers” does not tell them whether to wait or ask again. Name the purchase and the search status. If you do not know the timing, do not promise a date just to make the message sound settled.

In an example, you have asked a hotel for an invoice copy. Your accountant only needs to know which trip it belongs to and that you will send it later. There is no need to forward the entire exchange with reception if it does not matter for processing.

When adding to a period already handed over

An addition should clearly connect to the original handover. Say that it contains only newly added documents. Do not resend the entire month without explanation; the recipient would have to compare what changed and what they have already processed.

For an invoice that arrived late, add the receipt date if it explains the delay. Leave the document unchanged and let your accountant decide how to process it.

When the supplier sends a corrected version

A correction requires more than replacing a file in a shared folder. Your accountant may already have downloaded or processed the original. Explain what changed and clearly connect both versions. If their relationship is unclear, include the supplier's explanation.

The same template works if you accidentally send another business’s document. Identify the wrong file and its replacement so your accountant can correct it without having to ask again.
