> How Plain's CRM integrations work, and what they sync in each direction.

Plain's CRM integrations brings your customer and account data into Plain, so your team has full context on the customer and the account as soon as a thread starts.

Note: All CRM integrations, including Salesforce, Hubspot, and Attio, are available on our Horizon and Frontier plans.

## Key capabilities

* **Sync customer data automatically**: contacts and accounts from your CRM appear in Plain as customers and companies

* **Add context to every thread**: see customer and company details in Plain as soon as a thread starts

* **Write back to your CRM**: add notes or tickets in your CRM when work happens in Plain
