Send AR statement to a single customer
accounting:readSends an AR statement to a single customer account for the requested period. The per-account counterpart to the bulk endpoint above; mirrors the same template, gating, and 4-layer customer-email guard.
Industry parity: NetSuite “Email Statement” single-customer action, QuickBooks Online single-customer Statements view, Acumatica per-customer statement send.
Email gating: subject to the entity statement_email notification toggle
(default OFF) and per-account opt-out + global unsubscribe + template unsubscribe.
When gated, returns { skipped: true, reason: 'notification_disabled', preference }
with HTTP 200; the call still succeeds at the API contract level.
