Cross-Company Vendor & 1099 Data Appearing Across Separate QBO Files (Different EINs)

mm123456 · ‎January 29, 2026

I manage multiple QuickBooks Online companies with separate subscriptions and different EINs.

Recently, vendors began appearing in a company where they were never paid (no bills, checks, expenses, or bank transactions). This also impacted 1099 previews.

After investigation, the issue appears to have started when the same online banking credentials were used to connect bank feeds across multiple QBO companies. Bank feeds are now disconnected and separate banking logins are being established.

Important context:

• Each company has its own EIN and subscription

• Vendors are not shared between companies

• The affected vendor was never paid in the other company

• No 1099s were e-filed through QuickBooks

This appears to be a cross-company data integrity / identity-mapping issue, not duplicate entry or cleanup within a single file.

I am looking for guidance on:

1. Whether this type of cross-company vendor contamination can be fully resolved via Intuit backend escalation

2. Best practices to prevent recurrence once bank feeds are reconnected

3. When a clean forward strategy or rebuild is truly necessary vs escalation

I appreciate insights from ProAdvisors or Intuit moderators who have seen this scenario before.

Hi there, mm123456.

We appreciate your thorough investigation of the potential root cause related to shared online banking credentials across bank feeds. Let me explain this further below.

Yes, you are correct that using the same online banking credentials or bank across multiple QuickBooks Online companies can cause transactions to be downloaded into the wrong company file when vendors are paid using the same connected bank account.

If the transactions do not belong to a specific company, you can exclude them to remove them from the file and prevent any impact on vendor records or 1099 previews. This ensures the accuracy and integrity of your financial data for each company.

After reviewing your issue, I want to clarify that this matter cannot be escalated to Intuit’s backend team. QuickBooks Online does not support cross-company vendor sharing or synchronization. Each company file operates independently. Issues like this appear from the way data was imported or exported, or from how banking credentials were utilized.

Based on what you’ve shared, a clean-forward approach, along with setting up separate bank feeds, will resolve the issue. However, if the data overlap is more extensive, starting fresh with a rebuild can be the best option.

For additional questions or concerns, you can leave a comment below.

No it’s not working and I have tried to reach out to QuickBooks to speak to someone higher up on the technical support team but have had no success. I’ve been transferred, left in hold for hours, calls never returned by expert team. I refuse to believe that this issue is impossible to resolve. I can’t be the only person with this issue. I have since set up separate login credentials for each company on both the QBO side and my bank, but the cross pollination of information still exists in each company. It would be very helpful if someone from QB could contact me to help clean up the data and confirm that the data will be correct moving forward. I was even willing to to pay for an expert to help and was told by an expert that I would tecoa call back that same day to move forward with the process but I was never contacted again. This was over a week ago. I’m so disappointed with the level of customer support that QB provides.
