Automate a sales-to-CS handoff when a HubSpot deal closes won using Zapier

Prerequisites

Step 1: Set up the HubSpot trigger

Create a new Zap. Choose HubSpot as the trigger:

• Trigger event: Updated Deal Stage
• Pipeline: Select your sales pipeline
• Stage: Select "Closed Won"

This fires only when a deal enters the Closed Won stage — no extra filtering needed.

Step 2: Configure additional deal properties

In the trigger setup, under Additional Properties to Retrieve, add:

• dealname
• amount
• closedate
• hubspot_owner_id
• contract_length (if you use a custom property)
• description

Step 3: Look up the deal owner

Add a HubSpot action step:

• Action event: Get Owner
• Owner ID: Map the hubspot_owner_id from the trigger

This resolves the owner ID to a name and email you can include in the Slack message.

Step 4: Send Slack notification to CS channel

Add a Slack action:

• Action event: Send Channel Message
• Channel: #cs-handoffs
• Message Text:

:tada: *New Closed-Won Deal — CS Handoff*
 
*Deal:* {{dealname}}
*Value:* ${{amount}}
*Sales Rep:* {{owner_first_name}} {{owner_last_name}}
*Close Date:* {{closedate}}
*Contract Length:* {{contract_length}}
 
*Primary Contact:* {{contact_name}} — {{contact_email}}
 
<https://app.hubspot.com/contacts/YOUR_PORTAL_ID/deal/{{hs_object_id}}|View Deal in HubSpot>

For richer formatting, use Webhooks by Zapier to POST Block Kit JSON directly to the Slack API:

• Method: POST
• URL: https://slack.com/api/chat.postMessage
• Headers: Authorization: Bearer xoxb-your-bot-token

Step 5: Create a HubSpot task for CS

Add a HubSpot action step:

• Action event: Create Task
• Task Subject: Onboarding: {{dealname}}
• Task Body: New closed-won deal ready for CS onboarding. Value: ${{amount}}. Sales rep: {{owner_first_name}} {{owner_last_name}}. Contact: {{contact_email}}
• Priority: High
• Status: Not Started
• Owner: Select or map to your CS rep

Step 6: Test and publish

1. Click Test on each step
2. Move a test deal to Closed Won in HubSpot and verify the Slack message and task appear
3. Turn the Zap On

Cost and task usage

• Free plan: Works for a simple 2-step Zap (trigger + Slack). 100 tasks/month.
• Professional plan: $29.99/mo for the full multi-step version (trigger + owner lookup + Slack + HubSpot task = 4 steps). Each closed-won deal uses 4 tasks.
• If you close 10 deals/month, that's ~40 tasks — well within any plan.

Limitations

• Polling delay: 1-15 minutes depending on plan. The CS team won't be notified instantly.
• Single CS rep: Zapier's built-in HubSpot actions don't support dynamic owner assignment based on deal properties. For routing logic, you'd need a Code by Zapier step.
• No associated contacts: The trigger returns the deal but not its associated contacts. To include contact info, add a "Find Contact" step that searches by company or deal association.

Next steps

• Add contact lookup — add a HubSpot "Find Contact" step to pull the primary contact's name, email, and phone number
• Dynamic CS routing — add a Code by Zapier step that maps deal size or region to the appropriate CS rep owner ID
• Onboarding project — add an Asana or Monday.com step to create an onboarding project alongside the HubSpot task
