• For services — three-clause rule under s. 13(2) — compliant invoice (a), late invoice (b), residual (c) — timely invoicing within Rule 47 protects taxpayer.

• RCM — goods 30-day window (s. 12(3)(c)); services 60-day window (s. 13(3)(b)) — longer for services reflecting payment-cycle reality.

• For rate-change events, Section 14 six-scenario matrix — supply before/after × invoice + payment timing. 4-working-day bank-credit proviso prevents arbitrage.

13. KEY TAKEAWAYS — CHAPTER OVERVIEW

• Chapter IV is the temporal + valuation framework — Sec 12-13 determine WHEN tax liability arises; Sec 15 determines on WHAT VALUE.

• For goods, Sec 12 earlier-of rule operates from default; sequencing of invoice/payment relative to removal/delivery is critical.

• For services, Sec 13 three-clause framework links compliance to Rule 47 invoice timing — timely invoicing protects taxpayer from time-of-supply pushback.

• RCM differential — goods 30-day vs services 60-day reflects payment-cycle reality. Recipient's earliest-of-three / earlier-of-two computation framework.

• Section 14 six-scenario matrix governs every rate-change event — taxpayer planning around rate changes operates within this discipline.

• Section 15 valuation framework — transaction value default + Rules 27-35 — operates symmetrically for supplier (tax) and recipient (ITC).

• Fiat India SC doctrine + Rules 28-31 govern related-party / non-arm's-length valuation — operative for inter-company supplies, distinct-persons under s. 25(4).

• Post-supply discounts (s. 15(3)(b)) — three conditions strictly construed; Circular 92/11/2019-GST framework.

• Bharti Airtel substance-over-form discipline + Vatika prospective-operation framework anchor time + value analyses across all amendments.
