Our team is struggling with data synchronization between our CRM and marketing automation tool, leading to duplicate customer records. What's the best way to fix this?

To resolve duplicate customer records between Salesforce and HubSpot, follow these steps:

1. Check Integration Settings: Ensure that the integration is correctly configured with the right API credentials and that both systems have the necessary permissions. In HubSpot, go to Settings > Integrations > Salesforce, and in Salesforce, check Connected Apps.
2. Review Sync Rules: Look at the synchronization rules in both platforms to make sure they are set to avoid duplicates, such as using unique identifiers like email addresses or custom IDs. Adjust matching criteria if needed.
3. Clean Up Existing Data: Before syncing, clean up any existing duplicate records in both systems using deduplication tools. In Salesforce, use Data Loader or duplicate management rules; in HubSpot, use the contacts deduplication feature.
4. Test with a Small Dataset: Start by syncing a small subset of data, like a test group of contacts, to identify any issues without affecting the entire database. Monitor logs for errors.
5. Use Middleware if Needed: If native integration fails, consider using an integration platform like Zapier, MuleSoft, or a custom middleware to handle data mapping, validation, and error handling more flexibly.
6. Monitor and Adjust: After implementation, regularly monitor sync logs in both systems, set up alerts for failures, and adjust rules as necessary to prevent future duplicates. Schedule periodic audits.

For best practices, establish a clear data governance policy, document integration processes, and train your team on data entry standards to minimize issues.
