In an increasingly global marketplace, the issue of logistics as it relates to the supply chain is a key factor in the success of any business that relies on moving components, materials, parts, or products from one place to another. Let’s go over supply chain logistics and discuss some of the main challenges that can make it difficult, along with some potential solutions.

What is supply chain logistics?

In very basic terms, supply chain logistics is the process of managing the transportation and distribution of materials, components, parts, goods, and/or finished products throughout a business’ supply chain. In broad terms, supply chain logistics includes factoring for transportation issues beginning during the sourcing and procurement phase of the supply chain, through production, warehousing, inventory management, transportation/distribution, and even customer service and managing returns, sometimes called “reverse logistics.”

Supply chain logistics must account for both inbound logistics (which deals with the way materials, components, supplies, or necessary finished products are acquired and brought into a business organization), and outbound logistics (which deals with the way any finished goods or products produced by the business are moved to retailers and/or direct to customers).

What are the main benefits of effective supply chain logistics?

Supply chain logistics is vital for the smooth operation of any business, whether it be primarily a local operation with mainly localized sourcing/production and distribution, or a global organization relying on multiple, separate sections of the “chain” beginning and/or ending in diverse locations. Let’s quickly go over the primary benefits of implementing effective supply chain logistics.

1. Cost savings

Every management team (and shareholder group) is constantly pushing to lower operational costs, and efficient, streamlined logistics processes help reduce material and time expenditures. Wasted inventory, overstocking expenses, emergency price cuts to reduce warehousing overages, and inefficient logistics-related workforce management expenses are avoided when logistics are functioning properly. Transportation costs are reduced when shipping/delivery routes are optimized, and by buying key supplies in bulk at the right time, the business can benefit from the economy of scale, while still maintaining an effective minimum of a supply cushion in warehousing or manufacturing.

2. Improved efficiency and quicker delivery

An efficient supply chain logistics system speeds up product flow, which ultimately leads to faster order fulfillment and quicker delivery times for customers. When customers receive their orders quickly and reliably, they become repeat customers, which improves a business’s reputation and grows revenue. AI-assisted software and automation systems in warehouses, transportation, manufacturing, and order fulfillment improve the overall speed and accuracy of logistics operations. Optimized routes save time and money, helping ensure the necessary amount of stock is available at the right location at the right time, easing inventory management and facilitating just-in-time manufacturing where appropriate. Normalized on-time deliveries and real-time tracking improve the customer experience and further build confidence and loyalty.

A well-managed reverse-logistics/return operation also benefits customers, whether this involves retail returns or for recycling/disposal where appropriate. Easy, accurate returns have been shown to increase customer loyalty.

3. Flexibility and agility

In a volatile marketplace, effective logistics enables businesses to quickly respond to rapid spikes in demand or other supply chain disruptions such as extreme weather, supplier delays or stockouts, pandemics, and natural disasters, and lessen the impact of these events.

4. Competitive advantage

Streamlined supply chain logistics enables quicker time to market, which can give businesses a competitive edge over competitors relying on spotty or slow supply chains. Efficient logistics also enables businesses to expand their geographical reach and grow their markets by serving more customers in more locations. We mentioned the importance of an improved customer experience above, but it bears repeating here: when your company can provide faster, more reliable delivery times, this becomes a differentiator for customers, who may regularly give you their business even if your prices are slightly higher than competitors’.

5. Data-driven decision making

Today’s advanced logistics systems provide vital data on inventory levels, transportation issues, warehousing inefficiencies, and more, empowering management teams to make informed decisions regarding stock levels, replenishment cycles, and demand forecasting.

6. Improved sustainability

In addition to saving costs, when businesses optimize transportation routes, implement efficient transportation methods, and even reduce packaging waste, it leads to a smaller carbon footprint. This is not only good for the planet, but it can improve a company’s reputation and attract new customers via appropriate marketing and PR strategies.

7. Stronger supplier relationships

Effective supply chain logistics fosters better communication and cooperation between sources/suppliers and businesses. Expectations are more clear and goals are more attainable, leading to better supplier evaluations and long-term relationships that can lower costs and encourage collaboration and innovation.

Top 5 supply chain logistics problems and potential solutions

Now let’s go over some common supply chain logistics challenges and some ways their impacts may be lessened.

1. Supply chain disruptions

We mentioned supply chain disruptions above, and this is one of the more significant challenges in supply chain logistics. Political instability or social upheavals, natural disasters, extreme weather events, labor strikes, pandemics, economic downturns, and unexpected transportation delays are some of the more common and disruptive factors that face modern supply chain logistics teams.

Potential solutions include:

• Diversification of sourcing, suppliers, and vendors: Most companies can benefit here, though it may be more expensive up front to utilize a wider range of sources or suppliers. For example, obtaining certain raw materials from one country may be costlier compared to sourcing those materials from another country. However, if there are serious supply chain disruptions that slow or prevent the flow of materials from the formerly cheaper source, the pricier backup source may seem like a godsend. Similarly, good suppliers will understand a company’s need to maintain relationships with alternative suppliers in case of supply chain breakdown. Maintaining multiple sources of materials and supply will help lessen the financial impact of any shortages, at least until suppliers’ excess inventory is used up. This can potentially stretch your available supply to cover a disruption.
• Maintaining an adequate supply/inventory buffer: As many businesses learned (or re-learned) during the recent pandemic, just-in-time (JIT) manufacturing is extremely susceptible to supply chain disruptions, and companies relying on this practice took a very long and expensive time to recover from major shortages. Some are still feeling the effects. Whether your business relies on JIT or not, consider maintaining a reasonable buffer inventory of key components and materials where possible. This excess inventory will require some expense for management and rotation, but if significant supply chain disruption occurs, the extra inventory will help see a company through until the supply chain returns to some semblance of normality. At the very least, it will lessen the blow.
• Developing alternative transportation plans: In some cases, it can be smart for companies to maintain two or three main transportation avenues to obtain their normal supply, with at least one being a different transport method altogether. For example, if a company is mostly reliant on shipping and ports for its supply, leaders should consider using air freight, rail, or trucking for moving a portion of that supply where possible. With two or three alternative, concurrent transportation plans in place, it can be much more seamless to close one down temporarily during a supply chain disruption and ramp up another one, as opposed to scrambling to set up a previously nonexistent alternative after the primary system is disrupted.
• Diversification of product lines and income sources: If your business sources, makes, or sells one thing and one thing only, you’re pretty locked in to that unique supply chain, and are therefore vulnerable to disruptions that threaten that supply. Maintaining a buffer inventory can alleviate some of that risk, but smarter businesses will consider adding a related product line, or even something completely different, to flesh out additional revenue streams.

2. Rising transportation costs

This is impacting everyone along the supply chain the past few years, since transportation is often one of the largest costs in supply chain logistics. Depending on your business, fluctuations in fuel prices, driver shortages/strikes, congestion in key transport hubs, and increased local or global demand can all create spikes in the cost of transportation.

Some solutions may include:

• Route optimization: Using advanced software to optimize delivery routes can significantly reduce transportation costs. By analyzing factors like traffic patterns, delivery windows, and road conditions, businesses can reduce fuel consumption and improve efficiency, cutting costs.
• Collaborative shipping: Smaller companies can often work together to consolidate shipments, thereby sharing transportation costs. Pooling resources and collaborating with other local businesses can help reduce the financial burden of rising transportation prices. Larger combined orders can merit lower group rates from shippers or delivery companies.
• Transportation mode optimization/diversification: Depending on the urgency of the shipment and the distance, businesses can explore alternative transportation methods, such as rail or sea freight for larger items, or peer-to-peer solutions for local delivery for smaller items.

3. Inventory management and stockouts

Striking the perfect balance between maintaining too much inventory (leading to excess storage and management costs) and too little inventory (leading to stockouts, missed sales opportunities, and angry customers) is a challenge for any supply chain logistics team. Due to the potential expense and damaged reputation resulting from stockouts, most businesses opt to maintain a little excess inventory and eat the added costs, in order to maintain that buffer we discussed above. However, there are other factors that may be addressed, including:

• Utilizing advanced inventory management and demand forecasting solutions: Today there are intelligent tools to help businesses better manage inventory and conduct meaningful demand forecasting. Inventory management systems (IMS) can track stock levels in real time, allowing businesses to make data-driven decisions about when to reorder. This can help prevent stockouts, assuming the lower levels of the supply chain aren’t impacted by severe disruptions. Today’s advanced demand forecasting solutions can combine historical data acquisition/analysis and artificial intelligence (AI) to help businesses predict customer demand more accurately. Accurate demand forecasting helps businesses anticipate fluctuations in supply, adjust production schedules, and make more informed inventory decisions.

4. Lack of transparency

A lack of visibility into any portion of the supply chain can lead to inefficiencies, delays, and poor decision-making. In many cases, companies are still relying on outdated systems, software, spreadsheets, fragmented data sources, and sometimes even actual paper trails that make it difficult to track shipments and monitor inventory effectively. Without end-to-end visibility, businesses cannot react quickly to changes or disruptions.

Potential solutions include:

• Real-time tracking technology: By using solutions incorporating GPS, RFID, and Internet of Things (IoT) devices, businesses can effectively monitor shipments and inventory in real time. This provides the data that enables better coordination between suppliers, manufacturers, last-mile personnel, and customers, to facilitate more rapid deliveries all along the supply chain.
• Supply chain management software (SCMS): Advanced SCMS and/or logistics software integrates data from various stages of the supply chain, giving businesses a centralized view of their operations and ideally facilitating integrated business planning (IBP). This allows for more effective supply/demand planning, resource allocation, and decision-making.

5. Labor shortages and other workforce challenges

Labor shortages are frequently a significant problem in supply chain logistics, particularly in warehousing, transportation, and last-mile delivery. It’s easy to recall the difficulties faced during the COVID-19 pandemic, as workers were forced to stay home or work remotely. Moreover, an aging workforce and the challenging nature of many logistics jobs have led to a lack of skilled workers in certain regions. Logistics-adjacent labor disruptions such as a truckers’ strike or similar issues can be very difficult to address, but a multi-faceted approach can have significant benefits, depending on your business and needs.

Potential solutions:

• Automating where possible: Implementing automation for repetitive tasks such as sorting, packing, shipping, and inventory management can help reduce dependence on unskilled labor. Technologies like robotics, optical sorting/conveyor systems, and potentially automated guided vehicles or drones for intel or delivery can reduce your business’s reliance on manual labor and increase efficiency. AI-enabled and learning software can be implemented for logistics data analysis, freeing up personnel to perform other needed tasks. Additionally, by offering competitive wages, benefits, and incentives, your company can attract and retain talent, reducing the chances of damaging labor shortages or walk-offs that can impact logistics efforts.

• Taking advantage of the gig economy: Some companies are turning to gig workers or third-party providers for flexible labor solutions, including peer-to-peer last-mile delivery drivers. If your business is impacted by spikes in demand during a particular season, gig workers can help you effectively and economically adjust to fluctuating demand and address labor shortages during peak seasons.
