Sprwt's internal plan tiers, from entry-level up, are Startup, Seed, Sprout (internally "Starter"), Bloom ("Base"), Orchard ("Pro") and Enterprise. Your account is tagged with one of these, and code throughout the admin checks it in two ways: some features require an exact tier (for example, a set of tiers like "Bloom, Orchard or Enterprise"), while others require at least a given tier using a Seed -> Sprout -> Bloom -> Orchard -> Enterprise ranking. In the current code, Startup isn't part of that ranking list at all, and an unrecognized tier defaults to the same rank as Seed, so a Startup account can end up passing an "at least Seed" check the same as a Seed account would - this looks more like a code quirk than a documented rule, so don't rely on it.

When you try to open a page or use a feature your plan doesn't include, Sprwt's behavior varies by page: some show an upgrade page that lists the higher-tier plans and what they include, while others simply redirect you back to the admin home with no explanation. Either way, if that happens unexpectedly, check whether the feature needs a higher plan or a separate module add-on. Your tier is set by Sprwt; see Sprwt Billing > How do I upgrade or change my Sprwt plan?
