Which apps does a new store actually need?

Fewer than the app store suggests. A workable first loadout is a review app (free tiers cover a new catalog), an email platform with an abandoned-cart flow (also free at small list sizes), and nothing else until a real gap appears. The platform itself already handles pages, basic analytics, and checkout. Add a page builder when paid traffic needs dedicated landing pages, and a helpdesk when support volume outgrows a shared inbox — not before.
