# Contacts and companies

> Which people Fuse pushes to your CRM, what they become in each one, and how existing records are updated without overwriting your data.

When Fuse finds a person worth reaching out to, it can add them to your CRM automatically, along with the company they work for.

## What gets created

|         | Attio   | HubSpot | Salesforce      | Zoho            | Pipedrive    |
| ------- | ------- | ------- | --------------- | --------------- | ------------ |
| Person  | Person  | Contact | Contact or Lead | Contact or Lead | Person       |
| Company | Company | Company | Account         | Account         | Organization |

On Salesforce and Zoho you choose whether people arrive as Contacts or Leads. The setting lives under **Settings → Integrations → *your CRM*** on the **Configuration** tab.

## Turning it on

Contact pushing is off until you enable it. In the Fuse app go to **Settings → Integrations**, choose your CRM, open the **Sync** tab, and turn on **Push contact records**. There is a matching **Push company records** toggle beside it.

<Warning>
  This matters more than it first appears. Everything else Fuse writes to your CRM attaches to a contact record, so while it is off, emails and engagement are skipped entirely rather than queued up for later.
</Warning>

## Which people are added

Fuse only pushes people it has **contact details** for, meaning an email address or a phone number.

This is deliberate. Someone you have no way to reach is not useful in a CRM, and most CRMs cannot reliably deduplicate a record with no email, so pushing them creates duplicates that are painful to clean up later.

If someone in a list is not appearing in your CRM, this is usually why. Enrich them and they will be included in the next sync.

## Updating existing records

Fuse matches on email address, so re-syncing the same person updates their existing record rather than creating a second one.

<Note>
  **Fuse will not overwrite what you already have.** When updating an existing record it only fills fields that are currently empty. If your team corrected someone's job title, that correction stands.

  The exception is a manual push, where you are explicitly asking Fuse to refresh a record. There, overwriting is the intent.
</Note>

## Choosing which fields sync

The **Fields** tab, under **Settings → Integrations → *your CRM***, lets you turn off individual fields Fuse would otherwise write, such as job title, phone, LinkedIn or company details.

Anything you turn off is left alone entirely, on both new and existing records.

## Companies

When Fuse adds someone it also creates or matches the company they work for and links the two, so your CRM keeps its people-to-company relationships intact.

Companies are matched on domain. If one already exists with that domain, Fuse links to it rather than creating a duplicate.

## How often it runs

Contact and company pushing runs in the background once an hour. Large first syncs are processed in batches, so a big list may take a few passes to appear in full.
