New Shopify POS customer, how to apply discount to a different subscription other than Basic

We are currently a Quickbooks POS customer but are about to start a migration to Shopify POS.

Shopify offers a discount for Quickbooks POS Desktop users, which we wish to take advantage of.

However, the promotion is for the Shopify Basic subscription. We wish to initiate a Shopify Small Business subscription to begin with. Does the discount apply to this subscription? If so is it the same discount or only a partial discount.

We would like to know the answer to this before starting the “trial” subscription. Thanks.
