Open-source vs SaaS: what does migration really cost?
SaaS looks cheaper on day one — until transaction fees and app subscriptions scale with your revenue. Compare the true 3-year total cost of ownership across platforms, and find the GMV where the cheaper option flips.
≈ €166.667/mo — the main driver of SaaS transaction fees.
Hosting & retainer apply to open-source platforms (you own the infra).
Rented on SaaS; built-in / owned on open-source.
