Microsoft Invoicing API
A lot of Office 365 API are available. Will Microsoft Invoicing have an API.
At least initially, APIs to change status of an Invoice from Open to Paid will help manage many businesses.

Would love to use this for my client, but without the ability to programmatically create invoices I cannot propose this as a solution.
I would like the API idea expanded. My billing is very detailed, O365 services, Azure services, professional services, all collected n SQL during the month. I would like the ability to update the invoice line items via an API. Alternatively, it would serve just as well to be able to upload a .json file with the invoice details each month. The ability to change an invoice status via an API is less valuable to me.
