The startup (credits) subscription is created and controlled by the underlying billing account and offer type. In that subscription, creating additional subscriptions is only allowed if the billing account and agreement type support it and if the account has the required permissions. When the portal says “not eligible for creating new subscription,” it typically means either:
- The current offer type (for example, a startup/credit or promotional offer) is limited to a single subscription, or
- The billing account doesn’t allow additional subscriptions to be created from that offer, or
- The signed‑in identity doesn’t have the necessary billing role on the billing account.
To create a new subscription when eligible:
- Sign in to the Azure portal.
- Go to Subscriptions and select Add.
- On Basics, enter a Subscription name, then select the Billing account, Billing profile, and Invoice section where the subscription should be created.
- Choose the Plan (for example, Microsoft Azure Plan or Microsoft Azure Plan for DevTest).
- On Advanced, select the Subscription directory, optional Management group, and Subscription owners.
- Optionally add Tags, then select Review + create and complete creation.
If the Add option is disabled or the flow ends with a “not eligible” message, the startup offer’s billing account is not allowed to create more subscriptions. In that case, the supported options are:
- Use the existing startup subscription for workloads covered by the credits, or
- Create a separate, standard Pay‑As‑You‑Go/Microsoft Customer Agreement subscription under a different eligible billing account (for example, a personal or organizational payment method), or
- If this is part of a partner or startup program, contact program support or open an Azure support request from the portal to confirm whether additional subscriptions can be enabled for that billing account.
For programmatic creation, use the subscription‑creation REST APIs appropriate for the agreement type (EA, MCA, or MPA) as documented, but these APIs still honor the same eligibility and billing‑account limits.
