Is “Contacts harmonisation with push to Xero” on my plan?

Contacts harmonisation with push to Xero sits at the Standard tier of the Accounts module. A feature opens when its tier is at or below the level your subscription holds for the module. Why it sits there: Only the bulk push and its undo are claimed — the single push and the master record are shared with Basic supplier and payment-run screens. Your level is on Settings → Subscriptions.
