Common Operational Questions
How do caterers calculate grocery quantities for 500 guests?
Caterers use standardized per-head grammage formulas: 100g paneer (50kg), 18g desi ghee (9kg), 55g basmati rice (27.5kg), 180ml milk (90L), and 220g mixed vegetables (110kg) for a standard 4-course North Indian wedding feast.
What is the average food cost percentage in Indian wedding catering?
In well-managed Indian catering operations, raw food grocery cost accounts for 22% to 28% of total retail plate price, leaving a 40%+ gross operating margin after labor and transport.
How does catering software prevent kitchen grocery over-purchasing?
Venura Catering OS automatically converts confirmed guest counts into exact wholesale kg weights based on recipe grammages, generating standardized purchase orders that eliminate manual guesswork.
How does catering management software sync with Tally Prime?
