Finin2min GST Desk·June 2026·7 min readMONTH CLOSE

GST filing quality improves when the month close has dates, owners and freeze points. A 10-day discipline can prevent rushed GSTR-1/3B filing and missed ITC/RCM.

10-day close model

Day range	Close activity
Day 1–2	Sales cut-off, e-invoice and credit-note check.
Day 3–4	Purchase register clean-up and vendor follow-up.
Day 5	RCM, import of services and expense scan.
Day 6–7	GSTR-1 outward reconciliation and sign-off.
Day 8–10	2B/ITC, 3B liability and payment approval.

Owner matrix

Sales/accounts receivable owns outward invoice cut-off.
AP owns purchase register and vendor correction.
GST owner owns 1/3B/2B bridge.
Controller approves payment/interest working.
CFO reviews material mismatches and cash impact.

Finin2min warning
