FBA vs FBM in India: Which Fulfillment Model is Right for You?

Every Amazon seller in India faces a fundamental decision: should you let Amazon handle your storage, packing, and shipping through Fulfillment by Amazon (FBA), or should you manage everything yourself with Fulfillment by Merchant (FBM)? The right choice depends on your product category, margins, order volume, and operational capacity. This guide breaks down both models so you can make an informed decision for your business.

Understanding FBA: Fulfillment by Amazon

With FBA, you send your inventory to Amazon's fulfilment centres across India. When a customer places an order, Amazon picks, packs, and ships the product. They also handle customer service and returns for FBA orders. Your products become eligible for Prime delivery, which significantly boosts visibility and conversion rates.

FBA fees in India include a fulfilment fee (based on product size and weight), storage fees (monthly charges per cubic foot), and optional services like labelling and prep. For a standard-size item weighing under 500g, the fulfilment fee typically ranges from Rs 25 to Rs 60 per unit. Storage fees vary by season, with higher rates during October to December to discourage long-term storage during peak demand periods.

Understanding FBM: Fulfillment by Merchant

With FBM, you store inventory in your own warehouse or facility and handle all shipping logistics yourself. You are responsible for packing, dispatching, providing tracking information, and managing returns. This gives you complete control over the customer experience, packaging quality, and shipping timelines.

FBM sellers avoid FBA fulfilment and storage fees but must account for their own warehousing costs, courier charges, packaging materials, and staff salaries. For sellers already operating a warehouse for other channels like Flipkart or their own D2C website, FBM can be more cost-effective since the infrastructure is already in place.

Cost Comparison: When FBA Wins and When FBM Wins

FBA is generally more cost-effective for small, lightweight products with high turnover. If your product sells quickly, storage fees remain low and the per-unit fulfilment cost is competitive with most courier rates. The Prime badge also increases your sales velocity, which can offset the fees through higher volume.

FBM works better for large, heavy, or oversized items where FBA fees become prohibitively expensive. It is also preferable for slow-moving inventory, customised or made-to-order products, and fragile items that need special packaging. If you sell across multiple marketplaces simultaneously, FBM with a centralised warehouse gives you flexibility that FBA cannot match. Sellers with strong seller performance metrics can compete effectively even without the Prime badge.

The Hybrid Approach: Best of Both Worlds

Many successful Indian sellers use a hybrid model. They send their top 20-30 bestselling SKUs to FBA for Prime eligibility and faster delivery, while managing the long tail of their catalogue through FBM. This approach optimises costs while maintaining strong visibility for key products.

During major sale events like the Great Indian Festival or Prime Day, sellers often increase their FBA inventory for high-demand items while keeping everyday fulfilment through FBM. The key is to analyse your per-SKU economics regularly. Use your Amazon transaction reports and reconciliation data to track the true cost of each fulfilment method and adjust your strategy accordingly.

Key Factors for Indian Sellers to Consider

Geography matters significantly in India. If your customer base is concentrated in metro cities, FBA's fulfilment network provides excellent coverage. However, if you serve Tier 2 and Tier 3 cities, your own courier partnerships might offer better reach and rates. Consider your return rates as well — FBA handles returns seamlessly, while FBM returns require your own reverse logistics setup.

Cash flow is another crucial factor. FBA requires you to send inventory upfront and pay storage fees regardless of sales. FBM allows you to hold inventory locally and ship on demand, which can be better for capital-constrained sellers. Whatever model you choose, ensure your inventory management system supports real-time stock synchronisation to avoid overselling or stockouts.
