Frequently Asked Questions

How much does Shopify Plus cost per year?

Shopify Plus starts at $2,300/month ($27,600/year) but scales with GMV. High-volume merchants ($1M+/year) typically pay $3,000–$5,000/month ($36,000–$60,000/year) plus transaction fees of 0.15–2% per sale. A merchant doing $5M/year in sales pays $7,500–$100,000 in transaction fees alone.

When should I build a custom e-commerce platform instead of using Shopify Plus?

Build custom when: you exceed $2M/year in GMV (transaction fees become significant), you need full checkout customization, or you have complex B2B pricing models. A custom platform costs $30,000 to build with $2,000/year maintenance, eliminating all platform and transaction fees.

What are Shopify Plus transaction fees?

Shopify Plus charges 0.15% on Shopify Payments transactions and up to 2% on third-party payment gateways. For a merchant processing $5M/year, that is $7,500–$100,000/year in fees that go directly to Shopify, not your business. Custom e-commerce platforms have zero platform transaction fees.
