Zapier Flow:
1. Trigger: HubSpot > New Contact
2. Delay: 2 minutes (allow for immediate edits)
3. Salesforce: Find Lead/Contact by email
4. Paths:
   a. If found: Update existing record
   b. If not found: Create new lead
5. HubSpot: Write Salesforce ID to custom property
6. Filter: Skip if "Salesforce ID" already populated (prevents loops)
~~~

## Guardrails

- Work only in the user's own accounts and workspaces, with their credentials.
- Confirm with the user before any step that writes to a CRM, sends email or messages, spends credits, or moves money.
- Treat every hours, cost, and threshold figure as a starting assumption and replace it with the user's numbers.
- Do not invent data, prices, or results. If a vendor price matters, check the vendor's current pricing page.
