Evaluating When to Outsource Ecommerce Fulfillment

The reverse logistics sector, for instance, is projected to grow at a rate exceeding 20% annually. As companies grow, they typically progress through phases from founder-led fulfillment to fully outsourced models, utilizing 3PL partners for efficiency. This approach allows businesses to test new third-party logistics (3PL) partnerships before committing to full outsourcing.

Determining the right time to outsource ecommerce fulfillment is a pivotal decision for businesses seeking to optimize their operations. This decision often hinges on several key factors, including the time spent on fulfillment, operational challenges, and business growth phases.

Understanding the Triggers for Outsourcing

When ecommerce fulfillment demands exceed two hours daily, it may be time to consider outsourcing. Excessive time spent on fulfillment can lead to operational issues such as order errors and inventory mismanagement, putting additional strain on staff. This often results in an increase in customer complaints as employees become stretched thin.

Geographic expansion also necessitates a distributed inventory to efficiently meet customer demand in various regions. As businesses grow and diversify their sales channels, the complexity of fulfillment increases. This is particularly true for businesses that operate across multiple channels, where maintaining an efficient fulfillment process becomes increasingly challenging.

Phases of Fulfillment Maturity

The evolution of fulfillment strategies often follows distinct phases as businesses grow. In the initial phase, founders typically handle fulfillment themselves, using personal spaces for inventory management. As order volumes increase, businesses transition to phase two, hiring a small in-house team to manage the growing workload.

Phase three sees the adoption of a hybrid fulfillment model. At this stage, companies may choose to outsource specific SKUs or regions, while continuing to process local orders internally. This approach allows businesses to test new third-party logistics (3PL) partnerships before committing to full outsourcing.

In phase four, businesses fully outsource their fulfillment operations. 3PL partners manage warehousing and logistics negotiations, allowing businesses to focus on other priorities. The decision to transition from self-fulfillment to using a 3PL involves assessing product profiles, particularly considering factors such as fragility, which can impact fulfillment decisions.

Strategic Transition and Management

Transitioning to outsourced fulfillment requires strategic planning. It is advisable to document existing fulfillment processes and initiate the transition during a slow season to minimize disruptions. Leaving a period of overlap between old and new systems and maintaining regular check-ins with the 3PL partner can ensure a smooth transition.

Sharing forecasts with the 3PL and signing clear service level agreements are crucial steps in establishing a successful partnership. Ecommerce fulfillment metrics play a vital role in helping brands forecast operational capacity, especially during peak times like holiday surges, which can increase capacity needs up to tenfold.

Metrics such as Units Per Hour, Units Per Order, and Lines Per Order measure productivity and fulfillment efficiency. Understanding these metrics helps businesses optimize resource allocation, with higher units per order requiring more resources and space.

The Evolving Landscape of Ecommerce Fulfillment

The ecommerce fulfillment landscape has seen significant advancements in scope and sophistication over the past decade. As demand for direct-to-consumer ecommerce continues to grow at unprecedented rates, retailers are pushing logistics providers for improved speed, flexibility, choice, cost, and customer satisfaction.

Today's consumers expect seamless cross-channel shopping experiences. The expertise of 3PLs can help ecommerce businesses reduce costs, manage complex logistics functions, and implement innovative technologies. The reverse logistics sector, for instance, is projected to grow at a rate exceeding 20% annually.

Companies like Amazon and CEVA Logistics are making substantial investments in expanding their fulfillment capacities. Amazon boasts the second largest global 3PL warehousing network, with a significant market share in the United States. Meanwhile, CEVA Logistics expects a substantial portion of its future revenues to come from ecommerce, emphasizing investments in new fulfillment centers and automation technologies.

Investments in digital fulfillment platforms offer businesses end-to-end supply chain visibility, integrated order management solutions, and personalized analytics. Fulfillment providers are tailoring their services to meet the specific needs of brands, retailers, and marketplaces, with innovative models such as 'dark stores' and showrooms becoming more prevalent.

As the ecommerce sector continues to evolve, logistics companies face margin pressures due to the demands of B2C deliveries to residential addresses. However, advancements in technologies such as autonomous mobile robots and automated guided vehicles are enhancing efficiency in fulfillment centers, integrating with warehouse execution and management systems.

The last mile of ecommerce deliveries remains one of the most costly parts of the process, accounting for a significant portion of delivery expenses. To address this, businesses are increasingly positioning inventory closer to customers, thereby reducing shipping times and costs.

Overall, the evolution of ecommerce fulfillment will continue alongside the growth of the ecommerce sector, with a focus on improving service levels, shipping efficiency, and sustainability. As the industry advances, harnessing the power of artificial intelligence and other technologies will be key to maintaining competitiveness.
