About the product

Amma Enterprises supplies groceries and household brands to retailers around Kaikaluru, Andhra Pradesh — the kind of ordering that used to mean phone calls, handwritten lists and negotiated prices. Best Buy App turns that into a proper digital storefront: browse by brand and category, see wholesale pricing and bulk offers up front, order for delivery or pickup.

Wholesale ordering works differently from retail — customers buy cartons and dozens, not pieces. The platform handles it natively: minimum order values, quantity-tiered pricing, 'buy 10 get 1 free' style offers that auto-apply at cart, an Offer Zone listing every running deal, and pre-order support for stock that isn't on the shelf yet.

The same experience ships as an installable mobile app — the storefront is a progressive web app, so retailers get a real icon on their phone, the bottom-tab app navigation, and the same offers and account state as the website. The screens below are the actual running app.

Inside the platform

Wholesale catalog

Hundreds of FMCG SKUs organised by brand and department — biscuits, oils, detergents, personal care and more.

Bulk pricing & MOQ

Quantity-tiered pricing, minimum order values and carton/dozen units — the way wholesale actually sells.

Offer Zone & auto-apply

Running deals in one place; 'buy X get Y' and bulk offers apply themselves at cart — no coupon hunting.

Installable app

The storefront installs as a real app — home-screen icon, bottom-tab navigation, same account and offers.

Checkout flexibility

UPI and cash-on-delivery, delivery in 1–4 days, and saved items for repeat wholesale orders.

Pre-order & stock

Pre-order support for incoming stock and clear out-of-stock marking — retailers can plan purchases.

The challenge

  • Wholesale isn't retail — cartons and dozens, not pieces. Minimum order values, quantity-tiered pricing and 'buy 10 get 1 free' deals had to be native, not bolted on.
  • A large FMCG catalogue with hundreds of SKUs across 15+ departments — it had to stay browsable on a small phone screen with brand-first navigation.
  • Merchants run promotions constantly — offer banners, auto-apply deals and festival popups needed to be switchable without touching code.
  • Retailers order from the shop floor — the experience had to feel like a real app, not a desktop site squeezed into a browser.

What we built

  • A storefront built on the Vyapar commerce platform — catalog, cart, offers and order management sharing one backend with the merchant's own business app.
  • An offer engine made for wholesale: percentage discounts, bulk-tier deals and auto-apply promotions, plus an Offer Zone page listing every running deal.
  • Mobile-first app UX — bottom-tab navigation (Home, Categories, Saved, Cart, Account), sticky category rail, and an installable PWA so it sits on the home screen like a native app.
  • Wholesale checkout — UPI and COD, delivery and pickup options, saved items for repeat orders, and pre-order for incoming stock.
