Yes, Square partners with Sutton so that our funds are FDIC insured. However, Sutton does not administer our accounts, and they can not answer questions about them. Also, if you want things like automatic bank feeds for accounting software (I use Zoho Books), you do not look for Sutton Bank. Apps like Plaid that retrieve bank feeds have our accounts listed as Square Banking, not Sutton. (See screen shot below when I linked Square accounts to my bookkeeping software)
