Hi Stanislav Fotev,
Thanks for reaching out to Microsoft Q&A.
When you have multiple billing profiles in Azure, the invoices can indeed be generated on different days. Each billing profile operates independently, and the invoice date is based on when the billing cycle for that specific profile ends. So, depending on how the billing cycles are configured for each profile, invoices can come out on different days.
If you need all invoices to be generated on the same day, you may need to adjust the billing cycle settings for each profile accordingly. However, by default, they are likely to follow their individual billing cycles, which can result in invoices being issued on different days. You can check the specific billing cycle details for each profile in the Azure portal under Cost Management + Billing to confirm the exact dates for your setup.
