Where to buy
Go to Admin → Shop. The page lists the available plans and add-on bundles. Each item shows its price in TWD and USD and a description of what is included. Add items to cart, then check out to complete the purchase.
Upgrade vs add-on points
Upgrading the plan changes your monthly / annual subscription tier and gives you a new permanent ceiling on feature points (e.g. moving from Essentials to Growth). It also typically unlocks additional unrelated benefits — higher customer limits, more storage, priority support.
Buying add-on feature points keeps your current plan but adds a one-off or recurring boost to your feature-point ceiling. Use this when one or two extra features push you over the limit but you do not need the rest of the next plan tier.
