Hello @mkej,
Thank you for reaching out to us, we are here to help.
In theory, you can use 2 websites via one account, but what I think you will not get the outcome you are looking for. This is because, when you onboard a WooCommerce website to the Zettle plugin, it will generate the products in Zettle and link those to that WooCommerce website. Then, when you onboard a 2nd website, it will duplicate the library in Zettle and have 2 completely separate libraries available on Zettle. I would expect you are looking for the option to have 2 websites with the same products link to 1 version of this product on the Zettle library, correct?
I don’t think this is possible with our current setup. You might be able to link the products, but the updates would not flow correctly and one of your websites would not get update correctly when the other changes stock.
Please let me know if this answers your question and/or if you have any further questions for us.
Kind regards,
Joost
