How we picked these
We compared official pricing pages for nine SaaS ecommerce platforms, checking entry plans that sell online, transaction fees, sales caps, and free plans. We treated vendor pricing pages as the source for prices, and we noted where prices are quote-based.
How to compare SaaS ecommerce costs fairly
Compare the subscription, payment processing, platform transaction fees, and app costs together, since the cheapest plan is not always the cheapest store. Check sales caps, product limits, and whether your payment provider triggers an extra fee. Also check themes, shipping, tax, and discount features, since missing features often mean paid apps. Start on the lowest plan that covers payments, and upgrade only when sales or features require it.

Frequently asked questions
What is a SaaS ecommerce platform?
It is a hosted store platform where the vendor runs the software, hosting, and security for a monthly fee. You pay a subscription instead of building and hosting the store yourself.
Which SaaS platform is cheapest?
Ecwid and Square Online offer free plans for small catalogues, while Shopify and BigCommerce start at $39 per month. The cheapest total depends on sales volume, payment fees, and apps.
Does Shopify charge transaction fees?
Shopify does not add a platform fee when you use Shopify Payments, but outside payment providers trigger a fee on lower plans. Check the current fee on the plan you choose.
Can I move my store to another platform later?
You can export products, customers, and orders in most cases, but themes and some app data do not move cleanly. Keep backups of product data and content before you switch.
Is SaaS better than self-hosted ecommerce?
SaaS is easier to start and maintain, since hosting and updates are handled for you. Self-hosted options give more control, but they need technical skill for hosting, security, and updates.
