Online food delivery aggregator platforms like Swiggy and Zomato deduct multiple service charges before releasing weekly merchant payouts.

To determine true cloud kitchen or dine-in restaurant delivery profitability, owners must reconcile gross order value against raw material cost of goods sold (COGS) and fixed kitchen operational overheads.
Aggregators deduct base commission (18%–28%), 18% GST on commission, 1.8%–2% payment gateway charges, 1% TDS, 0.5% TCS, customer discount shares, and packaging fees. Combined, platform deductions frequently total 28% to 35% of order value.
Under Section 9(5) of the CGST Act, e-commerce operators (Swiggy and Zomato) are liable to pay 5% GST directly to the government on restaurant services delivered through their platform. Restaurants cannot claim Input Tax Credit (ITC) against this 5% rate.
Restaurants can optimize delivery margins by: (1) Setting higher delivery-specific menu prices (10%–20% above dine-in), (2) Creating high-margin combo meals, (3) Capping discount promotions at max ₹40–₹50, and (4) Encouraging repeat customers to order through direct WhatsApp or website ordering.
