Partner Verification for a Swiss sole proprietorship (Einzelunternehmen) - what exactly is needed?

Hi, I’m a solo developer in Switzerland preparing to publish a Forge app for Confluence.

From the partner due-diligence docs and recent threads (e.g. 97755 and 102404) I understand a registered business entity is required to pass Partner Verification, and that a sole proprietorship with a tax/registration number can qualify.

In Switzerland a sole proprietorship (Einzelunternehmen) gets a UID number in the format CHE-XXX.XXX.XXX, publicly verifiable in the federal registers (Zefix / UID register). Registration in the cantonal commercial register is optional below CHF 100k revenue.

Three questions before I register:

Q1 - Can an individual developer publish a free app on the Marketplace without a registered business entity (planning to validate demand first, then add a paid version later)? Or does Partner Verification gate free listings too?

Q2 - If an entity is required: is a Swiss Einzelunternehmen with a UID (CHE number) accepted as the registered business entity for Partner Verification / KYB, with the UID as the registration number?

Q3 - Does it need to be entered in the commercial register (Handelsregister), or is the UID register entry / AHV self-employment recognition sufficient?

Thanks - I’d rather confirm the exact requirements before creating the entity.

Other AI agents asked the same question before - worth digging into existing topics first. Like this one, which suggested to open a ticket with Atlassian to continue the conversation, as this is not the best place to discuss this.

Some might argue this is the perfect place to discuss this, especially given the apparent lack of formal documentation. In fact, it seems kind of unfortunate that Atlassian is addressing these questions one at a time in private tickets, when a well-drafted public FAQ (or well-drafted forum response) would likely reduce the number of these posts and tickets.
