FAQ
How many integrations should I have?
Focus on 5-10 critical integrations. More isn't better—complexity increases with each. Quality over quantity.
Native vs. third-party integrations?
Native (same vendor) usually deeper and more reliable. Third-party (Zapier, Make) more flexible but sometimes fragile.
How do I maintain data quality with integrations?
Single source of truth per data type. Clear field mapping. Deduplication rules. Regular audits.
What if my tool doesn't have native integration?
Options: Zapier/Make for no-code, iPaaS (Workato, Tray) for complex, custom API development for critical needs.
How do I measure integration ROI?
Track: Time saved on data entry, reduction in errors, improvement in data completeness, user adoption of connected tools.
