How to Merge Duplicate Vendors in QuickBooks Online (Step-by-Step Guide)

Share this article:

Keeping your vendor list clean in QuickBooks Online is essential for accurate bookkeeping and reporting. If you’ve created duplicate vendors, you can merge them so that all transactions are combined under a single profile.

Follow the step-by-step guide below:


Step 1: Go to Your Vendors List

Log in to your QuickBooks Online account, then go to Expenses > Vendors from the left navigation menu.

Step 2: Identify Duplicate Vendors

Review your vendor list and identify duplicates that need to be merged.

  • Decide which vendor you want to keep
  • Look for similar names that may refer to the same vendor

For example, vendors like “Costco” and “Costco Wholesale” may be duplicates.

Step 3: Rename the Duplicate Vendor

QuickBooks Online merges vendors by renaming one vendor to match another.

  • Open the duplicate vendor
  • Click Edit
  • Change the vendor name to exactly match the one you want to keep

Example: Rename “Costco” to “Costco Wholesale” to merge both vendors.

When you do this, QuickBooks may show a warning that the vendor name already exists. This is expected.

Scroll down to the bottom of the page and click Save to continue.
