BMO integration - August 2025

dq_circuit · ‎September 08, 2025

Has anyone else been experiencing issues with their QBO and BMO banking integration?

It's been down for us for about a month now with "Error 103 - username/password not working" error message (while we can log in directly to our bank profile with no issues). Numerous attempts to sign back in via QBO results in errors (and can even lock our banking profile account up as they see it as suspicious activity). 2FA doesn't seem to be the issue as it does ask for either the SMS code or our RSA code and results in the same error message.

Try opening your QBO account on any private/incognito browser. If the same error persists, use csv2qbo converter tool for the time being. It's a $60 one time license.
