Hi Antonio,
As Ludwig already mentioned, you can generate payment file from D365FO.
You can use standard configuration on Electronic reporting (e.g. ISO20022 Credit transfer) and connect it to the vendor method of payment
PS. Electronic Reporting Configs can be imported via Workspaces > Electronic reporting > Microsoft Repositories > Global

When payment file has been created (e.g. Pain.001), you can upload it manually on net bank or FTP server (i.e. If you have already integration to the bank to send and get file). Then you will to get the reception file (Pain.002) and you can import it into D365FO. It will change the payment status from "Sent" to "Received"
When the invoices has been paid, you can get return file (i.e. Camt054D) from net bank or FTP server and import in D365FO. It will change the payment status from "Received" to "Approved"
For automating this process you can evaluate using ISV.
