FAQs
Castiron is a popular platform for cottage food sellers, offering free website creation with a per-transaction fee model. While it's a solid starting point, the 5-10% fee on every sale adds up quickly — especially as your business grows. RestauNax offers everything Castiron does and more for a flat $4.99/month with zero transaction fees beyond standard payment processing.
Why Switch from Castiron?
Transaction Fees Kill Your Margins
Castiron charges 5-10% on every sale. On a $50 cookie order, that's $2.50-$5.00 going to Castiron — on top of Stripe's 2.9% + $0.30. With RestauNax, you pay $4.99/month flat and keep everything.
No Shipping Integration
Castiron doesn't integrate with FedEx, USPS, or UPS for automated shipping. RestauNax includes nationwide shipping with carrier integration, tracking numbers, and rate calculation.
No Loyalty Program
Castiron has no built-in loyalty or rewards system. RestauNax includes a full loyalty program — customers earn points and redeem rewards, driving repeat purchases.
No AI Marketing Tools
Castiron doesn't offer AI-powered food photography, social media content creation, or email marketing. RestauNax includes all of these at no extra cost.
No Mobile App
Castiron doesn't provide a branded mobile app for your customers. RestauNax includes a mobile app where customers can reorder, earn rewards, and receive push notifications.

No automated carrier integration means you can't easily offer nationwide shipping with tracking.
No Growth Tools
No loyalty program, no AI marketing, no email campaigns — Castiron is a storefront, not a growth platform.
