Headless commerce gets pitched as the default answer to slow storefronts, and sometimes that's right. Often it isn't.
The honest case for going headless is catalog and merchandising complexity that a templated platform can't express, or performance requirements a monolithic platform structurally can't hit. If neither of those is true, headless just adds engineering overhead for a problem a good theme could have solved.
We ask three questions before recommending it: does your catalog or checkout logic outgrow what a hosted platform allows, does page performance materially affect your conversion rate today, and does your team have the engineering capacity to own a decoupled system long-term.
When the answer to those is yes, the payoff is real — Northgate Outfitters saw mobile conversion increase 64% after their rebuild. When the answer is no, we'll say so, even if it means a smaller project.
