You do not need a Premium Bank Connections connection to get Chase statements. Chase transactions and statements come in through a MasterCard or MX connection. Add a Premium Bank Connections connection only if you also want Chase check images.
Today LedgerSync adds Chase transactions and statements as one MX connection. If you chose Checks, it also adds a Premium Bank Connections connection called Chase Bank (Images).
If you prefer MasterCard, click Pick Manually in the Add Bank Connection window and choose Statements & Transactions (Using Mastercard API). MasterCard also brings in Chase transactions and statements.
Once your client enables Third Party Access for your read-only accountant login in Chase, you can use that login to connect Chase through MasterCard.
Chase may not provide statements through Third Party Access. If statements don't arrive, connect with the account owner's login.
Chase connections through MasterCard and MX use Chase's own sign-in page. After you sign in, Chase shows the accounts it can share and lets you choose which ones to connect. Choose only the accounts you want in LedgerSync.
If a connection brings in an account you don't want, you can delete it:
