SaaS Integrations Strategy: Which Ones to Build First and Why
Integrations are a growth lever, a retention tool, and a competitive moat — but building them in the wrong order is an expensive distraction. Most SaaS founders build integrations their users do not use rather than the integrations that drive adoption, reduce churn, and generate new customer acquisition.
The Business Value
SaaS integrations serve three distinct business functions: they drive adoption (a product that connects to tools users already rely on fits into existing workflows, dramatically reducing activation friction); they increase retention (a product embedded in a customer’s technology stack through multiple integrations is significantly harder to replace); and they drive acquisition (a listing in the integration marketplace of a popular SaaS product exposes the product to every user of that platform who is looking for a complement to their existing stack).
How to Decide Which Integrations to Build
Step 1: Survey your entire user base about their existing tool stack
Send a single-question email to all active users: ‘Which 3 tools do you use alongside [Product] in your daily workflow?’ The responses reveal the tools most commonly used alongside the product — and therefore the integrations that would eliminate the most friction for the most users.
Step 2: Prioritise by integration type and user impact
Four integration types by value: (1) Data input integrations (pull data from external tools into the product, eliminating manual data entry) — the highest-value type; (2) Data output integrations (push data from the product to external tools) — high retention value; (3) Trigger integrations (external event triggers a product action) — high automation value; (4) Notification integrations (push alerts to communication tools) — high engagement value.
Step 3: Evaluate build effort vs acquisition value
Some integrations are high-effort to build but available to a large, captive audience through a marketplace listing (Salesforce AppExchange, HubSpot App Marketplace). The acquisition value of a marketplace listing may justify a higher build investment than an equivalent integration accessed only through the product’s own settings.
Step 4: Use Zapier and Make.com as a first-pass integration layer
Before building direct integrations, connect the product to Zapier and Make.com. These platforms provide access to 3,000+ pre-built integrations through a no-code automation layer, enabling users to connect the product to their existing tools without the product’s team building each integration directly. This validates which integrations users actually use before investing in direct integration builds.

A Prioritisation Reference
| Integration Type | Example | Business Value | Build Priority |
|---|---|---|---|
| Data input (pull from external tool) | Pull client data from HubSpot CRM into the reporting product | Eliminates manual data entry; highest activation and retention impact | Highest |
| Authentication (SSO / OAuth) | Log in with Google or Microsoft | Reduces sign-up friction; required for enterprise buyers with SSO mandates | High |
| Notification (push to communication tool) | Send Slack alert when a report is ready | Increases engagement and daily active use; easy to build via webhook | Medium-high |
| Data output (push to external tool) | Export generated reports to Google Drive automatically | Reduces friction in existing workflow; retention value | Medium |
| Marketplace listing | List in HubSpot App Marketplace or Zapier | Acquisition channel; reaches captive audience of potential users | Medium (depends on marketplace fit) |
Q: How many integrations should an MVP have at launch?
One or two well-built, well-documented integrations to the tools that the majority of target users rely on are more valuable than five partially built integrations that do not work reliably. SA recommends: a payment integration (Stripe, always), an email or notification integration (Slack or email), and one data source integration to the most commonly cited external tool in user surveys.
Q: How do I know if a specific integration is worth the build investment?
Estimate the build cost and compare it to the estimated revenue impact: new customers who name the integration as a decision factor, plus retained customers who would have churned without the integration, multiplied by their average monthly revenue. An integration that costs $3,000 to build and prevents 5 churns per year at $99/month average revenue has a 6-month payback period — a clear positive return.
Q: Should I build integrations myself or use a third-party integration platform like Paragon or Prismatic?
At the MVP stage, build integrations natively in Bubble.io using the API Connector and backend workflows. Third-party integration platforms provide a managed layer for building and maintaining multiple integrations at scale and are appropriate when the product has 10+ integrations to maintain. For a product with 2-5 integrations, native Bubble.io integration is more cost-effective and more flexible.
