How Dexon Computes Composite Solar Supply

On a ₹1,00,000 turnkey solar installation project, manual calculations often lead to audit penalties. Dexon structures the invoice with absolute statutory precision:

• Total Contract Package Value: ₹1,00,000
• 70% Goods Supply (Panels, Inverters, Structures): ₹70,000 @ 5% GST = ₹3,500 Tax
• 30% Service Supply (Civil, Erection, Grid Sync): ₹30,000 @ 18% GST = ₹5,400 Tax
= Total Statutory Tax: ₹8,900 | Grand Total: ₹1,08,900 (Statutory Audit Proof)
