Sellfy vs Square Online: pros and cons
Sellfy
Sellfy offers flat monthly pricing with 0% platform transaction fees, 20GB file uploads, subscriptions, and built-in email plus affiliate marketing — no code needed. Plans run $22–$119 a month, but yearly sales caps and Business-tier gating on key growth tools are real limits. Overall, it's a solid pick for creators selling digital products without per-sale fees.
Pros
- Charges 0% transaction fees on all plans, so a $10 ebook sale keeps its full price minus only the standard PayPal/Stripe processing fee — the site contrasts this with Gumroad's 10% per-sale cut.
- Supports digital uploads up to 20GB per file on Premium (15GB on Business, 10GB on Starter), enough for full video courses, music packs, and design bundles without external file hosting.
- Bundles email marketing, affiliate programs, SEO, product upselling, and cart abandonment recovery into the dashboard, replacing separate subscriptions to tools like Kit ($0–$1000/mo) or Refersion ($99/mo).
Cons
- Plans are capped by annual sales volume ($10k Starter, $50k Business, $200k Premium); exceeding your cap without upgrading can trigger a 2% overage fee on the excess revenue.
- The 0% transaction fee claim excludes payment processing — PayPal or Stripe still takes roughly 2.9% + 30¢ per sale, and payouts depend on those gateways being available in your country.
- Cart abandonment, affiliate marketing, upselling, custom fields, and removing Sellfy branding are all gated behind the Business plan ($59/mo yearly) or higher, so the entry tier omits key growth tools.
Square Online
Square Online makes it easy to launch a store that shares inventory, orders, and payments with your Square POS, and the free plan with included hosting removes upfront costs. Design flexibility is limited and you're tied to Square's ecosystem for payments. Overall, it's a low-risk pick for Square users, but less compelling for anyone else.
Pros
- Free plan with free web hosting lets you launch a store with no upfront infrastructure cost
- Inventory, orders, and payments sync natively between Square POS and the online store, eliminating manual reconciliation
- No coding or web design experience is required to publish a professional-looking site
Cons
- Design and customization are more limited than what dedicated website builders or self-hosted platforms like WooCommerce offer
- The tightest benefits only apply if you stay within the Square ecosystem, so merchants using other payment processors or POS systems get less value
- Advanced ecommerce features and lower processing rates generally require moving up to paid plans, and costs grow as you add capabilities
