A practical field guide from Automation Ace.
The short answer
If the trigger and the result both live in HubSpot, use a HubSpot workflow. Examples are rotating leads, setting lifecycle stages, creating tasks, enrolling contacts in sequences, and notifying owners. When the workflow has to reach another app, such as a project tool, accounting system, database, or Slack channel with custom logic, use Zapier. Many teams use both: HubSpot handles CRM logic, and a webhook hands off to Zapier for everything outside it. Decide which system owns each property so they never overwrite each other.
What HubSpot workflows do well
HubSpot workflows run inside your CRM. They enroll contacts, companies, deals, tickets, and other records based on property values, form submissions, list membership, or events, then carry out actions with delays and if/then branches. Common actions include:
- Setting and clearing properties, such as lifecycle stage and lead status
- Rotating records between owners and creating tasks
- Sending internal notifications and marketing emails
- Enrolling contacts in sequences and creating associated records
- On higher tiers, sending webhooks and running custom code
Because workflows run inside HubSpot, they react fast, use HubSpot's own property names, and don't use Zapier tasks. Workflow features depend on your hub and tier. Full workflows are generally on Professional and Enterprise plans, and webhook and custom code actions need specific tiers, so check what your plan includes.
What Zapier adds
Zapier connects HubSpot to thousands of other apps. Use it to create a project when a deal closes, add a paying customer to accounting, send form leads from another tool into HubSpot, or update a database. It also offers Formatter, Paths, lookups, Code steps, and AI steps for logic HubSpot can't handle on your plan. See the HubSpot Zapier automation guide for common builds.
The trade-offs are task usage, a second place to maintain logic, and trigger speed. Many app triggers check for changes on a schedule rather than instantly. See polling vs instant triggers.
Side-by-side comparison
| HubSpot workflows | Zapier | |
|---|---|---|
| Best for | Logic inside HubSpot | Connecting HubSpot to other apps |
| Speed | Runs in HubSpot as records change | Instant with webhooks, otherwise on a polling schedule |
| Cost | Included in your HubSpot tier | Uses Zapier tasks |
| Delays and enrollment rules | Built in, including re-enrollment | Delay steps; you manage repeats yourself |
| Other apps | Limited to native integrations, webhooks, and code | Thousands of app integrations |
| Who maintains it | HubSpot admins | Whoever owns the Zapier account |
Use HubSpot workflows when
- The trigger and every action are HubSpot records and properties.
- You need enrollment and re-enrollment rules, delays, or sequences.
- You want CRM logic visible to HubSpot admins in one place.
- HubSpot's own integration already syncs the other app, such as a native calendar or email integration.
Use Zapier when
- Data comes from, or needs to go to, an app HubSpot doesn't integrate with natively.
- You need logic your HubSpot tier doesn't include, such as lookups, code, or AI.
- The same process spans several tools, such as form, CRM, project tool, and accounting.
- Your team already maintains its other automations in Zapier. See Zapier vs native app automations.
Using both: the webhook hand-off
A clean pattern is to let HubSpot decide when and let Zapier handle what happens elsewhere:
- A HubSpot workflow enrolls a deal when it moves to Closed Won.
- If your plan includes the webhook action, the workflow sends the deal ID to a Webhooks by Zapier Catch Hook trigger, which starts the Zap immediately. Otherwise, use Zapier's HubSpot trigger for the stage change.
- The Zap looks up the full deal, creates the project and the invoice in other apps, and writes the project link back to a HubSpot property that only Zapier writes.
This keeps CRM rules in HubSpot, cross-app work in Zapier, and one property owner for each field. See API vs webhook and the sales pipeline automation playbook.
Pitfalls to avoid
- Two systems writing the same property: a workflow and a Zap both set lifecycle stage or owner, and the last one wins. Give each property one owner. See preventing two automations from updating the same record.
- Loops: a Zap updates a property that re-enrolls the record in a workflow, which triggers the Zap again. See why a Zap gets stuck in a loop.
- Duplicates: creating contacts from several sources without searching by email first. See why a Zapier search doesn't find the record.
- Property names: Zapier and the API use HubSpot's internal property names, which can differ from the labels people see.
- Undocumented logic: list every workflow and Zap that touches a property, so the next person can follow the chain. See why multiple automations trigger on the same record.
Frequently asked questions
Should I use HubSpot workflows or Zapier?
Use HubSpot workflows when the trigger and the result are both inside HubSpot, such as lead rotation, lifecycle stages, tasks, and internal notifications. Use Zapier when the workflow needs another app, such as a project tool, accounting system, form tool, or database.
Do I need a paid HubSpot plan for workflows?
Full workflows are generally included on Professional and Enterprise tiers, and some actions, such as custom code and webhooks, need specific hubs or tiers. Check HubSpot's current plan details for what your account includes.
Can a HubSpot workflow trigger a Zap?
Yes. If your plan includes the webhook action, a workflow can send a webhook to a Webhooks by Zapier Catch Hook trigger, which starts the Zap immediately. Otherwise, Zapier's HubSpot triggers can watch for the change.
How do I stop HubSpot workflows and Zaps from conflicting?
Decide which system owns each property, so only one of them writes it. Add a source or last-updated-by property, and check it before writing to avoid loops.
