Do these every period to avoid notices and lost credit.
Issue correct invoices
Check GSTIN, place of supply, tax rate and invoice numbering on every invoice.
Reconcile purchases
Match your purchase register with supplier-reported data before claiming input credit.
File on time
Late filing attracts fees and interest; set reminders ahead of the due dates.
Keep records
Retain invoices, returns and working papers for the period required by law.
Key takeaway. Monthly reconciliation prevents most GST problems. Rates and rules change, so confirm current rules.
