It depends on the size of the job and how much the store matters to your business.
A freelancer is a great fit for a small, well-defined task on a tighter budget – a specific feature, a bug, a design tweak. You get direct access and lower cost. The risks are capacity (one person, one set of skills) and continuity if they’re unavailable.
An agency makes sense when a store needs a range of skills at once – performance, UX, development, security – plus reliability and cover so work doesn’t stall when one person is away. That breadth and continuity costs more, and it’s worth it when the store’s revenue depends on staying fast and up.
The honest test: for a one-off task, a good freelancer is fine; for a store you genuinely depend on, an agency’s breadth and continuity usually wins. Judge either one the same way – on measurable results for real clients. More: what it costs · managed WooCommerce
