Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FastSpring

  • Pricing is not published and requires contacting sales for a quote, making cost comparison difficult upfront.
  • As a merchant-of-record, FastSpring takes on more control of the checkout and payment relationship than a pure payment gateway like Stripe.
  • Revenue share pricing can become more expensive than flat per-transaction gateway fees at very high volumes.
  • Primarily targeted at software/digital goods sellers, so it is less suited to physical product e-commerce.

Square for Retail

  • Limited customer support with primarily email and online forums, slow response times for urgent issues
  • Internet connectivity required for normal operations; weak signal impacts transaction processing and experience
  • Restricted to Square's payment processing with higher transaction fees compared to some competitors
  • Limited to iOS devices and Square's proprietary hardware, excluding Android or third-party devices
  • Limited advanced retail capabilities and deeper third-party integrations compared to enterprise POS systems
