FAIRNESS ORACLE · DUAL-MODE VISION · $0 INFRA

Stop losing ₹40 of every ₹100.
The Wholesale Fairness Oracle for India's 63M Kiranas.

Indian retail distributors routinely exploit opacity and informal credit. MARGINS scans GTIN barcodes and handwritten paper invoices (parchis), calculates fair wholesale bands via GS1 & Agmarknet, whispers dialect counter-arguments, and orders directly on ONDC.

CASE STUDY · RAJAJINAGAR, BENGALURU

How Amar saved ₹1,840 on a single Tuesday delivery restock.

Amar runs an independent 450 sq.ft. provision store in Bengaluru. When his FMCG distributor dropped off a delivery with a handwritten parchi bill of ₹38,400, Amar scanned the crumpled receipt using MARGINS.

“Distributors always say 'rates have gone up this week'. With MARGINS, I pointed my camera at the parchi, and within 3 seconds it highlighted that the oil distributor withheld the official 6% seasonal discount. I played the Hindi audio counter-argument, and he immediately gave me a ₹1,840 UPI credit.”
