Selling on Amazon, Flipkart, Myntra, Meesho, eBay, Walmart and more — set up, listed, advertised and run day to day by one team, with orders and stock synced to your store and ERP.
Marketplace management, end to end
India, the USA, the UK and Europe — one team across every marketplace you sell on.
What We Do
Everything a brand or retailer needs to sell on third-party marketplaces, from the first seller account to daily operations.
Registration, documents, category and brand approvals, tax details and shipping or fulfilment settings, done right the first time.
Bulk listing creation and clean-up: titles, bullets, descriptions, images, variations and category mapping written for each marketplace's rules and search.
Campaign setup, keyword research, bids, budgets and reporting on each marketplace's own ad platform, from Amazon Ads to Walmart Connect.
Daily checks on account health, policy notices, pricing, stock and the featured offer, so problems are caught before they cost sales.
Returns, reimbursement claims and settlement reports matched against orders, so you know what each marketplace actually paid.
Orders, stock, prices and products synced between the marketplaces and your Magento, Shopify, BigCommerce, WooCommerce or Shopware store and your ERP.
What Is Marketplace Management
Marketplace management is the work of selling on third-party marketplaces such as Amazon, Flipkart, eBay and Walmart: opening and verifying seller accounts, creating and optimising listings, running the marketplace's own advertising, keeping account health, pricing and stock in order, handling returns and claims, and reconciling payouts. MageBytes manages this for brands and retailers selling in India, the USA, the UK and Europe. Because we also build ecommerce stores and ERP integrations, we connect each marketplace to your store and back office, so orders, inventory and prices stay in step without manual uploads.
Plan My Marketplace GrowthFrom Amazon.in and Flipkart to Walmart, OnBuy and Amazon's European stores — managed the same way.
We're an ecommerce and ERP development team, so marketplaces connect to your systems rather than living in spreadsheets.
Sales, ad spend, fees and returns by marketplace and product, reconciled against what was paid out.
How We Work
We start with the marketplaces that fit your catalogue, then add more once the first ones run smoothly.
We review your catalogue, margins, fulfilment and existing seller accounts, then recommend which marketplaces and regions to start with.
Seller accounts are registered or cleaned up, documents prepared, and category or brand approvals applied for where needed.
Listings are created or optimised in bulk, and orders, stock and prices are connected to your store or ERP.
Campaigns go live with budgets and targets agreed with you, then are tuned from real search-term data.
Daily account checks, weekly ad optimisation and a monthly report on sales, spend, fees and returns per marketplace.
In Depth
The same product sells very differently on Flipkart, Walmart, OnBuy and Amazon.de. These are the marketplaces we work with in each region and what to plan for.
Amazon.in and Flipkart are India's major general marketplaces. Myntra and Ajio focus on fashion, Nykaa on beauty, Meesho on value-led categories, and JioMart and Tata CLiQ add further reach. Each has its own seller panel — Amazon Seller Central, Flipkart Seller Hub, the Myntra Partner Portal and the Meesho Supplier Panel — with different documents, fulfilment models and payout cycles.
Planning usually comes down to GST registration, cash-on-delivery and return-to-origin rates, and whether the marketplace or you handle fulfilment.
Amazon.com is the starting point for most brands, with Walmart Marketplace the usual second channel; Walmart reviews each application and expects a US-registered business. eBay suits branded, refurbished and parts catalogues, Etsy handmade and vintage goods, and TikTok Shop products that sell through video and creators. Wayfair works with home and furniture suppliers through its own supplier programme.
Amazon.co.uk and eBay UK carry most UK marketplace sales, with OnBuy as a growing general marketplace, TikTok Shop UK for social-led products and Wayfair UK for home and furniture suppliers. Sellers need UK VAT arrangements in place, and since Brexit, stock for UK and EU customers is planned and taxed separately.
Amazon runs separate stores in Germany, France, Italy, Spain, the Netherlands, Sweden, Poland, Belgium and Ireland, and eBay runs local sites in several European countries. Many European retailers also run their own marketplaces on Mirakl, which sellers join one by one.
Selling across the EU means VAT registrations where stock is held, extended producer responsibility (EPR) registrations in countries such as Germany and France, product safety details under the General Product Safety Regulation, and properly translated listings.
Every major marketplace runs its own ad platform: Amazon Ads (Sponsored Products, Sponsored Brands and display ads), Flipkart Ads, Meesho's ads in the Supplier Panel, eBay Promoted Listings and Walmart Connect's Sponsored Search. Each has its own targeting, bidding and attribution rules.
We research keywords per marketplace and language, manage bids and budgets weekly and report spend against sales. Results depend on product, price and competition, so we agree targets with you rather than promise a fixed return.
Selling on several marketplaces without integration leads to overselling and manual order entry. We connect marketplaces to your Magento, Shopify, BigCommerce, WooCommerce or Shopware store and to ERPs such as Business Central, Odoo, SAP Business One, Zoho or NetSuite.
For Amazon, Flipkart, Myntra and Meesho we build custom integrations through each marketplace's seller API, such as Amazon's Selling Partner API. For eBay, Etsy, Walmart and Mirakl-powered marketplaces, Connectra — our own sync platform, in Early Access — handles the sync.
