About the project

A marketplace for farm-fresh eco products where dozens of sellers share one platform. A shopper puts items from different farms in one basket and pays once.

  • One basket Items from several sellers in one order with a single payment.
  • Seller dashboard Products, orders and sales stats for every farm.
  • Ratings Seller and product ratings help pick a trusted farm.
  • Cashback Bonuses from each order towards the next one.
01 · The brief

40 eco sellers ran sales through Instagram with manual payment and delivery tracking — growth without a platform was impossible.

02 · What we built

We launched a multi-vendor marketplace on Next.js: unified cart and Stripe Connect checkout, seller dashboards, a rating system and a cashback loyalty program.

  1. Before Sales ran through Instagram, with payments and deliveries reconciled by hand.

    After One cart and one payment for products from several sellers.

  2. Before Without a platform sellers had nowhere to manage products and orders.

    After A seller dashboard: products, orders, statistics.

03 · The client’s path

How a person moves through the product, from the first step to the result the business needs.

  1. Picks a farm

    Seller and product ratings help choose a trusted one.

  2. Fills the cart

    Products from different farms in one order.

  3. Pays once

    One payment for products from several sellers.

  4. Gets cashback

    Bonuses from the order go towards the next purchase.

04 · What is inside the project

  1. A seller dashboard: products, orders, statistics

  2. One cart and checkout across several sellers

  3. Ratings and a loyalty program

Forecast

One cart across several vendors raises the average order by 10–20%, and vendors add products themselves without a marketplace manager. A guideline, not a promise.

05 · Architecture

How the product is put together: from what the user sees to the data and services behind it.

  2. Interface What a person sees and taps
