Tired of the Shopify tax?

You're not alone. Here's what merchants tell us every day.

Checkout locked behind Plus

Full checkout customization requires the $2,000+/month Plus plan. On standard plans, you're limited to colors and fonts.

14+ apps just to function

Reviews, email, upsells, analytics, subscriptions. Each app adds $10-50/month. Most stores spend $200-500/month on apps alone.

App bloat kills speed

Each app injects JavaScript into your storefront. 40% of visitors abandon sites that take more than 3 seconds to load.

2% gateway penalty

Use any payment processor other than Shopify Payments? That's 2% extra on every transaction. Effectively forces their gateway.

Hidden fee stacking

Transaction fees, processing fees, gateway penalties, app fees. Your actual cost is 3-4x the advertised plan price.

AI support gatekeeping

Need help? Good luck getting past the chatbot. Merchants report 20+ attempts to reach a human for complex issues.

Built different. Built better.

Everything you need, nothing you don't. No apps required.

Key Differentiator

Full checkout control on every plan

Custom fields, layouts, logic, A/B testing, trust badges, urgency elements. Everything Shopify locks behind Plus is standard here.

  • Custom checkout fields and validation
  • A/B test checkout flows and upsells
  • Post-purchase upsells built in
  • Full Liquid template access
