Need the invoice for the paid amount

Hi Georgios Vangelas,

Please note that this is Microsoft Q&A for Czech region. However since you have made this thread in English, so I will respond in English also.

If your subscription was purchased directly from Microsoft, you can usually download the invoice from your billing account.

For Microsoft 365 Personal/Family subscriptions:

1. Sign in to https://account.microsoft.com.
2. Go to Payment & Billing > Order history.
3. Locate the relevant purchase and open the order details to view or print the invoice/receipt.

For Microsoft 365 Business subscriptions:

1. Sign in to the Microsoft 365 Admin Center.
2. Navigate to Billing > Bills & payments (or Your products depending on the subscription type).
3. Select the appropriate billing period and download the invoice.

If the subscription was purchased through a Microsoft partner or reseller, the invoice would need to be obtained directly from that provider rather than from Microsoft.

If you're not sure whether this is a Personal, Family, or Business subscription, please let us know which product you purchased and we'll point you to the correct location.
