What types of products can I sell with Sellfy?

Sellfy supports a comprehensive range of product types to facilitate diverse business models. You can sell digital products (including eBooks, music, videos, PDFs, and software files up to 20GB in size), physical goods through its integrated print-on-demand service (like t-shirts, hoodies, and mugs), and recurring subscription products (for content, services, or memberships). This multi-format support allows you to manage your entire product portfolio from one centralized platform.

Does Sellfy charge any transaction fees?

No, Sellfy operates on a transparent pricing model with zero transaction fees across all its paid plans. You pay only your monthly or annual subscription fee, and you keep 100% of the revenue from every sale, apart from standard payment processor fees (e.g., from Stripe or PayPal). This model provides superior cost predictability and higher profitability compared to platforms that charge a percentage per transaction.

How does the print-on-demand service work?

Sellfy's print-on-demand (POD) service is fully integrated into your store dashboard. You simply upload your designs, select from a catalog of products (apparel, accessories, etc.), and set your retail price. When a customer places an order, Sellfy automatically forwards it to its network of 11 fulfillment partners. The partner prints the product, packages it, and ships it directly to your customer under your branding. You never handle inventory or manage logistics, and you earn the difference between your set retail price and the base production cost.

Can I embed my Sellfy store on my existing website or blog?

Yes, Sellfy provides multiple integration options to seamlessly embed your product store or individual "Buy Now" buttons into your existing website, blog, or landing pages built on platforms like WordPress, Webflow, or Squarespace.
