The GST Council's stated objective is universal B2B e-invoicing. After stepping down the threshold from ₹500 crore to ₹5 crore, proposals are actively evaluating lower limits down to ₹10 lakh to close the final unorganized tax reporting gap. Forward-thinking manufacturers are adopting native API-driven ERP systems now to avoid future disruption.
Every phase of GST e-invoicing implementation has brought greater transparency and tighter reconciliation cycles. In five years, the mandate moved from ₹500 crore to ₹100 crore, ₹50 crore, ₹20 crore, ₹10 crore, and ₹5 crore. Each step-down expanded compliance coverage by hundreds of thousands of registered businesses.
When lower thresholds take effect, small tiers of tier-2 job workers, metal platers, and component suppliers will be required to issue e-invoices. Main manufacturers relying on these vendors will face immediate credit blockages if their subcontractors lack automated billing systems.
To prepare your factory ecosystem for universal digital reporting:
Werkora equips every shop-floor supervisor, line operator, storekeeper, and accountant with their own dedicated login with plans sized for your operation.
Policy discussions indicate that universal B2B e-invoicing remains the ultimate target to automate GSTR-1 and eliminate synthetic ITC claims.
Factories can update tax rates and add units as their requirements change.
