Warehousing & Order Fulfillment Cost Reduction Guide for E-commerce Brands Using 3PL

Margins in ecommerce are shrinking faster than most brands realise.

According to industry estimates, logistics and fulfillment can contribute 12–20% of total ecommerce revenue. D2C brands can go even higher when returns and failed deliveries are included. Storage costs in metro cities are rising every year. Courier companies frequently revise their fuel and handling surcharges. Meanwhile, customers expect faster delivery, sometimes next-day, sometimes same-day.

The result? Many ecommerce brands scale revenue, but their profitability doesn't scale with it. In our experience working with growing brands, we've seen a common pattern:

• Inventory lying in warehouses for 90+ days.
• Brands paying for unused pallet space.
• Express shipping used unnecessarily.
• High return rates silently eat margins.
• 3PL invoices accepted without detailed audits.

The uncomfortable truth is this: most businesses don't realise they are overpaying their 3PL until cash flow becomes tight.

Cost reduction in warehousing and order fulfillment is not about squeezing your logistics partner. It's about operational clarity. When inventory planning improves, storage is optimised, order handling is streamlined, and KPIs are aligned with profitability, warehousing & order fulfillment costs naturally reduce.

Why Most Ecommerce Brands Overpay for Warehousing & 3PL Services

Today, most e-commerce brands overpay for warehousing and 3PL services.

1. Unused Storage Space

Many businesses usually pay for warehouse space whose inventory does not fully occupy it. They rent more space than they need and hence pay higher monthly rent.

2. Slow Moving Inventory

Slow-moving inventory and dead stock occupy valuable space in the warehouse. They do not generate any revenue but increase the business's storage costs. A 3PL company can use advanced software to track inventory in real time, reducing warehousing costs.

3. Excessive Pick And Pack Charges

Many 3PL companies in India charge per pick or per packaged product. These charges can compound when order fulfilment increases during peak seasons or holidays.

4. Multiple Handling Costs

When the inventory moves from the receiving zones to storage racks and dispatch zones, it increases handling and labour costs. Poor warehouse layout can increase multiple handling costs for the business.

5. Return Processing Inefficiencies

If the 3PL company does not manage the returns properly, then it can increase unnecessary costs. It even causes a delay in refunds, which can adversely affect brand reputation in the market.

6. Minimum Billing Clauses

Some 3PL companies in India charge a fixed amount from businesses even if they do not use all the services.

How Poor Operational Visibility Increases Warehousing And Fulfillment Costs?

1. No SKU Level Tracking

Some 3PL companies fail to track high and slow-selling products. This will overstock products and increase warehousing and fulfillment costs.

2. No Order Level Cost Breakdown

Many e-commerce brands look at the total bill for the services provided by a 3PL company. They do not give importance to the per-order cost breakdown, which eats away profit margins or increases unnecessary warehousing and fulfillment costs.

Optimise Inventory Before Negotiating With 3PL 

An e-commerce brand should streamline its inventory before partnering with the 3PL company in India. This will reduce the warehouse and fulfilment costs of a business.

Implement ABC Inventory Classification

The e-commerce business needs to classify inventory based on market demand. The business needs to classify highly valuable products in Class A. These products account for only 10-20% of the total SKUs but contribute 10-20% of the total revenue. Class B products are less demanding than Class A items, but they account for 15 to 25% of total revenue.

Class C products account for 50-60% of total products but are slow-moving compared to class A and class B products. These products increase the business's warehousing and fulfillment costs if they are not managed properly.

Reduce Deadstock And Ageing Inventory

An e-commerce brand needs to keep track of the products stored in the storage. The brand can set automated alerts within a gap of 30,60 or 90 days and identify fast-moving or slow-moving inventories and take action accordingly. It should introduce discounts or flash sales for slow-moving inventories so that they will clear out from the shelf quickly. The e-commerce brand can pair best-selling products with slow-moving items to clear out stock quickly.

Forecast Demand Using Data, Not Assumptions

Accurate demand forecasting can reduce warehousing and fulfillment costs. Relying on assumptions about data can lead to overstocking or understocking products. The e-commerce brand needs to review past sales data to identify sales trends. There will be many products that experience seasonal demands. The e-commerce brand can analyse the previous sales trend and prepare for the peak period accordingly.

Reduce Storage Costs Without Compromising Availability

Reducing warehousing and fulfillment costs does not mean reducing stock availability. The goal is to use the storage efficiently while ensuring faster order fulfilment.

Optimise Space Utilisation

The e-commerce brand needs to choose the proper storage format. For example, pallet storage is mainly for bulk cartons and fast-moving products. Again, bin or shelf storage is mainly for small, lightweight products. If a business stores lightweight products on pallets, then it wastes space and increases order fulfilment costs.

Usage Of Vertical Space 

Many e-commerce companies focus on the floor area of the warehouse while partnering with the 3PL company. However, the brand also needs to give importance to the vertical space of the warehouse. The brand can make use of the higher racking system to lower the cost per unit stored in the warehouse.

Implement Smart Racking Layout

The ecommerce brand can organise racks strategically to reduce warehousing and order fulfilment costs. For example, it can put fast-moving products near picking or packing zones to reduce picker travel time. Simultaneously, the brand can place slow-moving products in upper racks or the back of the warehouse. 

Eliminate Dead Zones

The e-commerce brand needs to identify dead zones (half-empty racks or unused corners) and rearrange inventory accordingly.

Lower Pick, Pack, and Fulfillment Costs 

Standardise Packaging Sizes

Usage of too many packaged products increases packing time and material waste. It even occupies more space inside the warehouse. E-commerce brands need to limit 4-6 standardised packaging sizes to cover almost 90 per cent of their orders. 

Reduce Multi-item Split Shipments

The business needs to reduce multi-item split shipments, i.e., they should store products in multiple warehouses of a 3PL company. Split shipments increase the business's picking, packaging, and shipping costs. The e-commerce brand can keep frequently purchased items together to reduce warehousing and fulfillment costs.

Optimise SKU Placement Inside The Warehouse

Keeping products anywhere in the warehouse can increase travel time and picking errors, and reduce warehousing and fulfillment costs.

The business can keep highly demanding products near packaging zones. It should keep slow-moving products in distant storage areas. The business can keep seasonal products near dispatch zones for easy picking and packaging.

Batch Picking VS Wave Picking

Batch picking means a single picker collects products of multiple customers at a time. 

However, in wave picking, the warehouse management system releases orders in groups based on various criteria, such as shipping destination.

E-commerce brands with high order density can implement batch picking to lower warehousing and fulfillment costs.

Reduce Shipping Costs Through Smarter 3PL Planning

Use Zone-based Inventory Distribution

The e-commerce brand needs to analyse from which city it gets the most orders. It needs to store top-selling products in the warehouse of the same city to fulfil orders quickly and reduce fulfillment costs.

Reduce Interstate Shipping Costs

Interstate shipments often cost more than intrastate shipments. The e-commerce brand needs to split inventory based on demand forecasting. It should use advanced software to route orders automatically. These strategies will reduce the shipping costs of the business.

Avoid Unnecessary Express Shipping

Many e-commerce brands spend money on express shipping without realizing its impact on the cost margin. The business should implement express shipping when the customer pays for it.

Control Returns And Reverse Logistics Cost

Analyse Return Reasons 

Most of the e-commerce brands track total return rates and neglect the return reasons. If a defective product is the primary reason, the business needs to inspect manufacturing quality and packaging materials to reduce costs.

Delivering the wrong size is one of the major reasons for returns and can increase shipping costs. The e-commerce brand can add a size guide or improve size charts with real measurements. Reducing size confusion can lead to lower return rates, especially in the fashion category.

COD rejection

Many customers choose cash on delivery as the payment method, but when the product arrives, they refuse to pay in cash. COD rejection increases unnecessary business costs. The e-commerce brand can mitigate such issues by offering order confirmation calls or partial COD payment at the time of booking. The brand can even deliver products to customers quickly to help them avoid COD rejection.

Faster Quality Check And Restocking Process

Return costs don't end when the product arrives at the warehouse. Delay in inspection and restocking increases the holding costs of the business.

The brand needs to inspect the returned products within 48 hours of arrival.

Smart Questions To Ask Before Outsourcing Or Renewing A 3PL Contract

Cost Structure Clarity Questions

• What are return handling charges?
• What is included in basic picking and packaging fees?
• What additional fees should I expect?

Technology And Reporting Questions

• Do you use WMS?
• Which e-commerce platform do you integrate with?
• How do you prevent picking errors?

Scalability And Peak Season Questions

• Can I distribute inventories in multiple warehouses?
• How do you handle products during peak seasons?
• What is your maximum daily order capacity?

Signs Your Warehousing Is Not Under Your Control

• If the storage costs rise but the order volume remains the same, then this indicates inefficient space utilisation inside the warehouse.
• If the total 3PL expenses divided by total shipped orders increases steadily, then it is because of additional picking fees or 
• If the return processing costs remain high because of slow quality checks, then it indicates that warehousing is not under the control of the e-commerce brand.

Operational Red Flags

• If the 3PL company makes frequent picking and shipping errors, the business should consider changing providers.
• If the 3PL company experiences delays in order processing, it indicates staff shortages or workflow inefficiencies.
• If the e-commerce brand wants to expand into new markets and the 3PL company cannot support it, then it is a red flag.

Final Words

The ecommerce brand should focus on improving efficiency while reducing warehousing and fulfillment costs.

The brand can streamline SKU placement, reduce picking errors, and optimise the packaging process to increase operational efficiency. It even reduces cost per order without compromising service quality.

Businesses should even track cost per order, storage expenses, and return reasons to prevent hidden charges. An e-commerce brand should even do a long-term partnership with a 3PL company. The right logistics partner supports scalability, provides pricing clarity, and delivers products to customers on time.
