Bank integration is not working on my Mercury account due to sign in error (103). However, I've confirmed my login works. What steps to overcome this Quickbooks bug?

Try opening your QBO account on any private/incognito browser. Did you encounter the same error message?

Same message in incognito and other browsers as well -- error 103.

Same error 103 in incognito and other browsers as well unfortunately.

You can use MT Online or one of the converter tools with a one time license (e.g csv2qbo @ $60) for the time being.

Thanks. What's the benefit of using MTO if Mercury already supports CSV exports?

Hello there, Ben. I'll point you in the right direction to get this sorted out and connect your Mercury account to QuickBooks Online (QBO).

Before anything else, know it isn't the experience we want you to have when connecting bank accounts inside the program. We recommend contacting our Customer Care Team so they can check on your account and conduct further investigation. This way, they can determine why you can't connect your Mercury bank account to your company file and provide other ways to help you through this. We'll write down the steps to get you going:

1. Access your QuickBooks Online company.
2. On the top right corner, click Help (?).
3. Select either Assistant or Search. Depending on what you choose, you can click Talk to a human, connect by starting a chat, or Get a callback.

6. Select the QuickBooks account, and click Next.
7. Map the columns, and click Next.
8. Select the transactions to import. and click Next.
