7 Ways Logistics Optimization Consultants Help Businesses Reduce Costs and Improve Delivery Performa

India's logistics cost has fallen to 10% to 10.7% of GDP in FY26, down from 13% to 14% a decade ago, according to a joint CII-Knight Frank report, following a cumulative infrastructure investment of $360 billion. That shift alone is translating into annual economy-wide savings of $123 billion to $133 billion. Yet the National Logistics Policy target remains 5% of GDP, and most of that remaining gap sits inside individual businesses, in the form of underused trucks, oversized safety stock, fragmented carrier contracts, and delivery networks that were never redesigned as order volumes changed.

This is the gap logistics optimization consultants are built to close. Rather than relying on infrastructure alone, they work at the operational level, inside a company's routes, warehouses, and carrier relationships, to convert national-level gains into measurable savings on a single P&L. India's global Logistics Performance Index ranking has already moved from 54th in 2014 to 38th in 2023, but businesses that have not restructured their own operations around this improved infrastructure are still paying costs closer to the old baseline.

Here are seven ways that shows up in practice.

1. Redesigning the Transport Mode Mix

Road transport still carries 60% to 65% of India's freight, even though rail and waterways cost significantly less per tonne moved. Consultants map freight lanes against this cost differential and identify which shipments can shift to rail or coastal movement without breaching delivery windows.

• Cost per tonne per kilometre: Rs 2.5 to Rs 3.0 by road, Rs 1.5 to Rs 1.8 by rail, and roughly Rs 1.0 to Rs 1.2 by waterways.
• Rail's share of the national freight mix has stayed close to 27% to 28% for years, well below the 45% target set for 2047 under the National Rail Plan.
• A 5 to 7 percentage point shift from road to rail has been estimated to protect 0.5% to 0.8% of GDP in logistics savings nationally, and the same ratio applies inside a single company's freight bill.

2. Improving Fleet and Route Utilization

An Indian truck covers just 250 to 300 kilometres a day on average, against 700 to 800 kilometres for a comparable US truck and over 500 kilometres in China. Consultants close this gap through route sequencing, load consolidation, and backhaul planning.

• Every 10% improvement in fleet utilization has been shown to cut long-haul freight rates by 6% to 7%.
• AI-assisted route optimization has been shown to produce routes 15% to 20% shorter than manual planning within 90 days of implementation.
• A large part of the utilization gap comes from trucks running empty on return legs, and building freight exchange or backhaul arrangements into a route plan is often the fastest way to lift daily kilometres covered without adding a single vehicle to the fleet.

3. Cutting Warehouse and Inventory Carrying Costs

Inventory sitting in a warehouse typically costs 15% to 30% of its value annually once storage, insurance, and working capital are accounted for, a cost most businesses track poorly because it rarely appears as a single line item. Consultants restructure safety stock levels, warehouse layouts, and demand forecasting to bring this down.

• Inventory optimization commonly reduces carrying costs by 10% to 25%.
• Warehouse management system implementation, done correctly, has been shown to improve labour productivity by 25% to 35% inside the same facility footprint.
• Reducing buffer stock from 90 days to 60 days on a single product line has been shown to cut its carrying cost by roughly 20%, without increasing stockout risk, once demand variability is actually measured rather than assumed.

4. Consolidating Freight and Renegotiating Carrier Contracts

Consultants identify where shipment volumes justify consolidation and where fragmented freight is quietly inflating cost per unit.

• Shipping full container loads instead of fragmented, less-than-container loads can cut per-unit freight cost by 35% to 50%.
• Structured carrier rate renegotiation using volume data and market benchmarks typically delivers 5% to 15% in immediate savings, often without any change to service levels or delivery commitments.

5. Deploying Transportation Management Systems

A large share of Indian logistics operations still run across disconnected spreadsheets, carrier portals, and warehouse systems that do not talk to each other, leading to suboptimal routing and mode decisions. Consultants close this gap by implementing transportation management systems that unify inbound and outbound freight visibility.

• A unified TMS typically delivers 10% to 20% in freight cost savings through better rate shopping and route selection.
• Real-time carrier performance data becomes available to procurement teams for the first time, replacing decisions previously made on outdated rate cards or informal relationships.

6. Rebuilding the Last-Mile Delivery Network

Last-mile delivery alone accounts for close to 40% of total logistics cost in India, more than any other single stage in the supply chain. Consultants redesign delivery zones, hub placement, and dispatch sequencing around actual order density rather than historical assumptions.

• AI-driven route planning applied specifically to last-mile networks has produced route lengths 15% to 20% shorter than manually planned routes.
• Trucks in India still lose six to eight hours per trip to manual checks and paperwork.
• Port dwell times of three to four days remain common against a global norm of one to two days, both of which a consultant can flag and route around before they affect a customer-facing delivery commitment.

7. Aligning Operations with Multimodal Infrastructure

India's 2047 freight modal shift targets rely on an estimated 216 multimodal logistics parks, each handling 16 to 17 million tonnes annually. Consultants help manufacturers and distributors plan their warehousing and distribution footprint around these emerging nodes early, rather than retrofitting logistics networks after a facility is already committed to a location.

• A well-run logistics park has been shown to cut total logistics costs by 10% to 12%, improve cargo turnaround by 20% to 25%, and reduce inventory requirements by 15% to 20% for businesses that route through it.
• Aggregating fragmented, sub-threshold cargo through an MMLP-grade interchange has also been shown to deliver a total cost advantage of up to 43% over standalone road freight on dedicated freight corridor routes, a saving only accessible to businesses whose networks are actually designed to route through these nodes.

Where This Adds Up

None of these seven levers work in isolation. A route optimization gain that is not backed by warehouse consolidation still leaves inventory sitting idle, and a carrier renegotiation without a transport mode review captures only part of the available savings. This is the coordination layer that IMARC Engineering's logistics optimization services are structured to provide, assessing a company's full freight, warehousing, and delivery network together rather than tackling one cost line at a time, for manufacturers and distributors operating across India's evolving logistics landscape.

Conclusion

India's logistics cost has dropped by nearly 4 percentage points of GDP over the past decade, but that national gain does not distribute itself evenly across every business. The companies capturing the largest share are the ones treating logistics as a structured, data-driven discipline rather than a series of one-off fixes, reviewing mode mix, fleet utilization, inventory, contracts, technology, last-mile design, and infrastructure alignment together instead of one at a time. With last-mile costs alone running at 40% of total spend, structured logistics optimization is one of the highest-return operational investments available today.
