How To Merge Accounts in Salesforce

You open Salesforce and suddenly notice the same company listed twice — different names, different contacts, different data scattered across both records.

Sound familiar? You’re not alone. Duplicate records cost sales teams up to 27% of their revenue due to wasted effort and poor data quality (Gartner). And in a CRM as powerful as Salesforce, dirty data is the silent pipeline killer.

The good news? Merging duplicate accounts in Salesforce is straightforward once you know the steps. This guide walks you through the whole thing — no fluff, just what you need.

Why Merging Accounts in Salesforce Actually Matters

Before we get into the how, let’s be clear on the why.

Duplicate accounts cause real damage:

• Sales reps waste time working on the same company twice
• Contacts, deals, and activities get split across records — causing confusion
• Reports and forecasts become unreliable
• Salesforce estimates that poor CRM data costs businesses an average of $15 million per year in lost productivity

Merging accounts fixes all of this. You combine records, preserve the data you want, and keep your CRM clean and trustworthy.

How To Merge Accounts in Salesforce

Here’s the step-by-step process — two methods depending on how you prefer to work.

Find the Duplicate Accounts First

You can’t merge what you can’t find. Salesforce has a built-in duplicate management tool, but the quickest way is a manual search.

• Go to the Accounts tab in Salesforce
• Search by company name, domain, or phone number
• Look for near-identical names (e.g., “Acme Corp” vs “Acme Corporation”)
• Check if the same contacts or emails appear across two records

Pro tip: Run a Salesforce report filtered by Account Name to surface duplicates at scale.

Merge Accounts Using the Salesforce Standard Method

This is the built-in way — available in Salesforce Classic and Lightning Experience.

Step 1 — Open one of the duplicate account records Navigate to the account you want to keep as the “master” record.

Step 2 — Click “Merge Accounts”

• In Lightning Experience: Go to the account, click the dropdown arrow next to “Edit,” and select Merge Accounts
• In Salesforce Classic: Scroll to the “Account Detail” section and click Merge Accounts

Step 3 — Search for the duplicate Salesforce will prompt you to search for accounts to merge with. Type in the duplicate account name and select it from the results.

Step 4 — Select up to 3 accounts to merge Salesforce allows you to merge up to 3 accounts at a time. Select all duplicates you want to combine into one.

Step 5 — Choose the master record This is the most important step. The master record is the one that survives. You’ll want to pick the record with the most complete and accurate data.

Step 6 — Pick field values to retain Salesforce shows you a side-by-side comparison of both records. For each field, select which value you want to keep — you’re in full control.

Step 7 — Click “Merge” Review your selections and confirm. Salesforce will:

• Merge all contacts, opportunities, cases, and activities into the master record
• Delete the non-master record(s)
• Log a merge event in the audit trail

⚠️ Merges cannot be undone. Double-check your field selections before clicking Merge.

What Happens to Related Records After a Merge?

This is the question most people miss — and it matters.

When you merge accounts in Salesforce, here’s what happens to each related object:

The deleted record is gone permanently — but all associated data is safely transferred to the master account. Nothing is lost.

Merge Accounts Using the Duplicate Management Tool

If you’re dealing with bulk duplicates, Salesforce’s Duplicate Management tool is a smarter move.

• Go to Setup → Duplicate Management → Duplicate Rules
• Turn on the Standard Account Duplicate Rule (if not already active)
• Salesforce will flag duplicates automatically and show a “Potential Duplicates” component on account records
• From there, you can review and merge flagged records directly

Research shows that 91% of CRM data is incomplete or inaccurate within 12 months of entry (SiriusDecisions). Setting up automated duplicate detection keeps your Salesforce clean on autopilot.

Common Mistakes to Avoid When Merging Accounts

A few things that trip people up:

Choosing the wrong master record Always pick the record with the most complete data as the master. If one record has 10 contacts and the other has 2, the one with 10 should probably be the master.

Not checking custom fields Standard fields are easy to review. But custom fields specific to your Salesforce org can be easy to overlook. Scroll through the full comparison before merging.

Merging accounts that shouldn’t be merged A company that rebranded is NOT the same company that acquired them. Before merging, verify both records actually belong to the same entity.

Forgetting about external integrations If your Salesforce is connected to marketing automation tools, billing systems, or other platforms — merging accounts can affect those integrations. Check with your admin before merging high-impact records.

Conclusion

Merging duplicate accounts in Salesforce is one of the quickest wins you can give your team. Cleaner data means better reports, better forecasting, and no more wasted effort chasing the same company twice.

The process is simple — find your duplicates, pick your master record, select the right field values, and confirm. Salesforce handles the rest.

Start with the highest-value accounts in your pipeline first. The ROI of clean data compounds fast — companies that use clean CRM data see a 10–20% increase in pipeline accuracy (Forrester).
