To get a better idea of the costs of using SharePoint Agents, I’d suggest you have a look at:
with the highlight being:
Under the PAYGO model, customers are billed $0.01 per message. Each interaction with a SharePoint agent uses thirty-two (32) messages, so customers are billed at $0.32 per interaction with SharePoint agents. The PAYGO meter uses your Azure subscription as the payment instrument, ensuring seamless integration with existing billing processes. This meter is available worldwide.
and
There are no in-product feature differences between the PAYGO meter, and the SharePoint agent included in the Microsoft 365 Copilot license. Users have the same capabilities and benefits, regardless of the billing model they choose.
Thus, with each interaction being $0.32, let say that typically a user will interact with SharePoint agents three times during any inquiry. That makes it about $1 per enquiry. If we now say that an average user will make 20 inquiries per day, that is $20 per user per day. Multiply that across all the users in an organisation and you can see how it could get very expensive very quickly.
Clearly then, pay as you go SharePoint agents is for very low volume of usage across the organisation, typically one enquiry per day. Otherwise, it make more sense to buy a full license of Microsoft 365 Copilot for the user in question because they effectively get unlimited SharePoint agent enquiries as well as a personal AI assistant plus more.
If you combine any other pay as go usage of Copilot, such as with Copilot Studio as I have outlined before, then it make far more sense to get a full Microsoft 365 Copilot for those who need to use any AI tools. However, pay as you go billing does provide you the flexibility to mix and match with full Microsoft 365 Copilot licenses. If you have a business with 5 major users and 20 casual users then teh starting point is for those 5 users to have full Microsoft 365 Copilot license, while the rest simply use an Azure subscription to cover any incidental costs until the point when another person in the business needs a full license.
To keep control of any SharePoint or Copilot pay as you go, you shoudl always set up a budget in Azure as I have outlined before with Security Copilot
Pay as you SharePoint agents do provide a degree of flexibility of quickly and easily enabling AI across your SharePoint information for your whole organisation but if usage of AI starts to grow then so too will the costs, and potentially quite dramatically if appropriate limits are not configured. The best option with pay as you go SharePoint agents then is its use in combination with full Microsoft 365 Copilot licenses for users who need to use AI extensively in their jobs, while casual users can remain on the pay as you go option. The good news is that you do have the flexibility to mix and match with the two types of licenses as needed and Azure does give you the added benefit of being able to turn off immediately where Microsoft 365 Copilot licenses are typically an annual commitment.
