+## Packages & limits
+- Review remaining events, guests, photos, and gallery days.
+- Upgrade the package or purchase add‑ons if limits are low.
+
+## Billing portal
+- Open the billing portal to update payment methods or invoices.
+- Use the package shop for upgrades when needed.
+
+## Data exports
+- Request a tenant‑wide or event‑specific export.
+- Large exports can take a few minutes; refresh the list to see progress.
+
+## Retention reminders
+- Check the gallery days limit to avoid expired access.
+- Use `post-event-wrapup` for archiving and compliance steps.
