# Companies Overview

> An overview of companies in Conversion.

Every contact in Conversion contains company data. This relationship helps you organize your data, run account-based campaigns, and maintain alignment with your Salesforce Account structure.

### How Companies Work

* **Salesforce Accounts** are synced as companies in Conversion
* **Companies can have many contacts** - just like in Salesforce, multiple people can work at the same organization
* **Company fields** include standard information like company name, industry, annual revenue, number of employees, and website. Contacts that aren't linked to a company still carry [default company fields](/product-docs/records/companies/default-fields).

## The Contact-Company Relationship

Company data in Conversion falls into two categories:

<Tabs>
  <Tab title="Linked to Salesforce Accounts">
    When a Salesforce Contact is associated with a Salesforce Account, that relationship carries over to Conversion. The Conversion company is linked to the Salesforce Account, and multiple contacts can belong to that company.

    **This happens when:**

    * Salesforce Accounts sync to Conversion
    * Salesforce Contacts with an Account ID sync to Conversion

    **In these cases:**

    * The company is linked to the Salesforce Account
    * Multiple contacts from the same Account share one company in Conversion
    * Company field updates sync between Conversion and Salesforce

    <Info>
      **Example:** A Salesforce Contact for [sarah@startup.io](mailto:sarah@startup.io) has a Salesforce Account "Startup Inc". When synced to Conversion, Sarah is linked to the Startup Inc company in Conversion. If another Contact from the Startup Inc Account syncs later with a different email, they'll be associated with the same company in Conversion.
    </Info>
  </Tab>

  <Tab title="Contacts with no Company">
    When a contact doesn't have an associated Salesforce Account, they still hold company-level information for that individual contact.

    **This happens when:**

    * Salesforce Leads sync to Conversion (Leads don't have Account associations)
    * Contacts are created directly in Conversion without a Salesforce link
    * Salesforce Contacts without an Account association sync to Conversion

    For Salesforce Leads, company field updates sync bi-directionally for Salesforce fields like `Industry` and `Company Name`

    These company fields can be accessed by opening the contact record in the Contacts tab.
  </Tab>
</Tabs>

### What Happens When Relationships Change

Conversion keeps your data consistent as relationships evolve in Salesforce. For example, when a Lead converts to a Contact, the contact in Conversion automatically re-links to the new Salesforce Contact record. If the Contact is associated with an Account, the contact moves to the corresponding company in Conversion.
