Our Verdict
If your primary need is professional and automated invoice generation, including features like custom templates, VAT/tax support, and compliance with specific regional regulations (like ZATCA), then Mega PDF Invoices is the better choice. It is likely easier to set up for its specific purpose. However, if you are looking for a more comprehensive automation solution to streamline various aspects of your store's operations, from order fulfillment to customer tagging and marketing integration, then Workflow Automation—React Flow is the more appropriate option. While it may require a steeper learning curve, its wider functionality can significantly improve efficiency across multiple areas of your business.
