Understand GST end-to-end as it applies to a software/SaaS/consulting OPC: when registration is required, monthly vs quarterly returns, the difference between B2B and B2C invoicing, how export of services works (LUT, zero-rated), reverse charge mechanism, input tax credit, and the GSTR-1 / GSTR-3B / GSTR-2B reconciliation cycle. GST is event sourcing with mandatory upstream reconciliation. Every invoice is an event. GSTR-1 is the projection over the period. GSTR-2B is the upstream consensus you must match. The reverse charge mechanism is a flipped event direction. Input tax credit is the rebate logic on cross-event matches. Same discipline as CQRS work — except disagreement triggers a government notice, not a Sentry alert. The monthly cadence is your event-loop tick. Miss a tick and the queue backs up; miss several ticks and the consumer (the GST officer) starts to wonder why the producer (you) is silent.
