What to establish before looking for the invoice
Microsoft 365 has charged you, but you cannot find the invoice in your email. Before searching your inbox again, find out who bought the subscription and who manages its billing in your company. For a business subscription, you can download the document from the admin center; ordinary access to Outlook does not give you this ability.
The aim is to obtain the original PDF for the right company and period. If you cannot access it yourself, the following steps will help you send a precise request to the person who manages the account.
First identify the purchase you need to document
Write down the subscription name, the company using it and the period you need. Add whether you bought directly from Microsoft or through your IT supplier. If you are unsure, check the order confirmation or ask whoever bought the licences.
This guide covers business subscriptions. For personal Microsoft 365, look in your personal account's order history. For a partner purchase, contact the partner supplying the service. Having licences in your business environment does not by itself establish who issues your bill.

An administrator opens the right account's billing
Ask an authorised billing administrator to open the Microsoft 365 admin center. In the dashboard view, go to Billing → Bills & payments; in the simplified view, go to Products → View invoices. Microsoft's instructions require the Billing Administrator role.
If the administrator sees several billing accounts, they must select the one associated with the purchase. An empty list does not necessarily mean the invoice does not exist. First check the account and date range. Then open the matching invoice and download its PDF using Download → Download invoice.

Billing → Billing accounts helps identify accounts. Microsoft distinguishes MCA and MOSA agreements, among others, and separate billing-account roles. If you are only collecting documents, the practical next step is simple: ask the current authorised administrator for the specific invoice. You do not need to take over the whole environment to obtain one PDF.
Match the downloaded PDF to what is actually missing
Open the file and compare the customer, invoice number, billed period and currency with your request. The issue date and service period do not necessarily describe the same day. For the handover, record both as stated by the supplier.
If you have two business subscriptions, for example, saving the first PDF containing the word Microsoft is not enough. In a fictional example, Lenka needs a document for company A, but the administrator first opens company B's account. Checking the customer catches the error before handover. Lenka marks the invoice as found only after receiving the PDF for company A.
Keep any payment document separately if your accountant needs it. Microsoft explains that card payments are matched using the invoice and card statement; its business services do not provide ordinary payment receipts.
If the invoice is still missing, send a request that can be followed up
You could write to the administrator or supplier: ‘Please send the original Microsoft 365 billing PDF for company A for September. We cannot see it in the account we checked. Can you confirm the correct billing account and period and whether the invoice has been issued?’
Include any known order or subscription number. If the reply says ‘not yet issued’, record it as an open item and name the person who will resolve it. Do not treat it as a completed handover.
Once you obtain the correct PDF, send it to your accountant with a short note identifying the company and period. The search is complete when the document matches the purchase and the recipient knows what it relates to.
