Thought i would chime in. Could be totally wrong on pricing.
The only reason not to use Moltin now for headless commerce would be the backend vs Shopify. Shopify is really easy to use and the ability to handle options, variants, images etc is just a pleasure (apart from the limitations of the 3 variants etc). From what i’ve seen with Moltin it’s ‘build your own backend or admin’. Certainly something Shopify made right.
If you’re headless first and have the time/money to build the backend and integrations, seems Moltin is a perfect fit.
Example: 1 item store with $99USD item. Average monthly is $74250USD.
Moltin.com - $315USD all inclusive with flow + events (CHEAPEST)
Commercelayer.io - $349 Euro a month which gets you 750 orders which gets you to $74,250.
Shopify.com - $299USD. If you pay $299USD + 0.5% its $372USD for the charges, so $299USD + $372USD = $671 all up.
Example 2: 1 item store with $99USD item. Average monthly is $400,000USD.
Moltin.com - $1785USD all inclusive (CHEAPEST)
Commercelayer.io - $349 Euro + $4935 Euro // Overage at 3290 orders x 1.5 euro. SHEESH i’m sure it changes at this kind of high level.
Shopify Plus - $2000USD + 0.2% - $800 = $2800USD
Shopify Advanced - $299USD + 0.5% = $2299USD
