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 commission 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.
Limited Multi-Language Support
Castiron is English-only. RestauNax supports 10+ languages, helping you reach customers in their preferred language.
Weaker SEO & Discoverability
Castiron's storefronts are hard to find via Google. RestauNax includes SEO-optimized pages and Google Reviews integration so new customers can discover you.

Per-Transaction Fees Add Up
At 5-10% per sale, a home baker doing $2,000/month in sales pays $100-$200 to Castiron — versus $4.99 flat with RestauNax.
No Shipping Integration
No automated carrier integration means you can't easily offer nationwide shipping with tracking.
Storefront, Not a Growth Platform
No email marketing, weak SEO, English-only — Castiron is a storefront, not a platform built to help you reach new customers.
