10 Zapier Integrations Every SaaS Startup Needs

If you're a SaaS startup and you're not running these 10 Zaps, you're paying for ops work that could be automated. Here's the standard pack.

1. New signup → Slack #signups

Trigger: Stripe customer created (or your DB webhook). Action: post to Slack with name, plan, MRR delta.

2. New paid signup → tag in HubSpot

When MRR crosses $0, auto-tag contact "PAID" in your CRM.

3. Cancellation → win-back drip

Subscription cancellation → 24h delay → add to Klaviyo "win-back" flow.

4. Failed payment → CSM notification

Stripe invoice.payment_failed → post in #support with customer name + amount.

5. Plan upgrade → discount eligibility

When customer upgrades from Free → Pro within 30 days of signup, auto-issue 20% off coupon.

6. Support ticket → Linear issue

New Intercom/Helpscout ticket tagged "bug" → create Linear issue → reply to customer with ticket #.

7. Form submission → CRM contact

Typeform/Tally submission → create or update HubSpot contact → notify sales.

8. New user → schedule onboarding email

Day 1 welcome, day 3 tutorial, day 7 case study — drip via Klaviyo or Customer.io triggered from Zapier.

9. Inactive trial → reactivation email

7 days into trial with zero usage → send "stuck somewhere?" email.

10. NPS response → notify CEO

NPS survey response of 9-10 (promoter) → ping the founder. Personal outreach > automation here.
