There are some people on Substack saying it's possible to connect 2 Subsatck publications to 1 Stripe account...

Here's the answer from Substack's team:

It's not possible to link two publications to the same Stripe account. You must have a separate Stripe account for each publication.

But Stripe makes it easy to manage multiple accounts, and you can have the money go to the same bank account.

Better always listen to what Substack says not "some people" on the internet or ChatGPT
