You can create powerful Zapier workflows by selecting a central source of truth to retrieve accurate information from, breaking down complex processes into multiple smaller Zaps, using functions and Sub-Zaps to save time and simplify collaboration, and implementing smart workarounds such as looping and custom app integrations. Monitoring Zaps with tools like Zapier Manager, email notifications, and status pages is also crucial to minimize the impact of failures in your workflow. By following these tips, you can create smarter, more efficient workflows that automate critical business processes.
