When you click Add Bank Connection in LedgerSync, you will see a screen asking: "What information would you like to aggregate?"
There are five connection options. This article explains each one — when to use it, what it fetches, and how to connect.

This is the default and most widely supported connection. Always try Mastercard first for any US bank. It provides the most reliable, automated statement and transaction feed across thousands of US financial institutions.

Use MX when the bank is not found in Mastercard, Mastercard is failing to connect, or you need to connect a Canadian bank for transactions. MX is currently in Beta. The rule: try Mastercard first, use MX as the fallback.
MX and Mastercard are independent data providers. Having both connected for the same bank is beneficial — LedgerSync cross-checks both feeds in the Bank Reconciliation Tool to give you higher confidence in your data.

Use Premium when you need check and deposit images — this is the only connection type that provides them. Also use Premium when the bank is not supported by Mastercard or MX for statements, or when those connections are being blocked by the bank's security systems.
Premium connections use the LedgerSync Desktop App to route the connection through a trusted local or hosted environment, improving reliability especially for banks that block cloud IP addresses.

Use this if your client banks with Mercury Bank. Mercury has a direct API integration with LedgerSync providing a seamless, stable connection without manual credential entry. LedgerSync endorses Mercury as the preferred small business banking partner. Not yet with Mercury? The connection picker includes a Register here link to open an account.
Use PDF upload when no live connection is available, the client can only provide downloaded PDF statements, or you need a one-time historical import. LedgerSync extracts transactions automatically using OCR and you can export to Excel, CSV, QBO, or OFX.
