Guide to Tendering for a New 3PL Supplier: Making the Right Choice for Your Business

Selecting the right Third-Party Logistics (3PL) provider is a crucial decision that can significantly impact your business’s efficiency, customer satisfaction, profit margins, and overall success. Whether you’re a fast-growing e-commerce business or an established company looking to optimise your supply chain, embarking on the journey to find a new 3PL partner requires careful planning and evaluation.

In this guide, we’ll walk you through the essential steps of tendering for a new 3PL supplier to ensure you make an informed choice.

Step 1: Assess Your Needs

Before you begin the tendering process, conducting a thorough assessment of your logistics and supply chain needs is vital. Consider factors such as order volume, peak seasons, delivery locations, sustainability, and any specialised requirements unique to your industry. By clearly understanding your business’s specific needs, you’ll be better prepared to evaluate potential 3PL providers and ensure they can effectively meet your requirements.

Step 2: Define Your Selection Criteria

Establish a set of clear selection criteria that will guide your evaluation of potential 3PL partners. Consider aspects such as location, technology capabilities, expertise in your industry, scalability, pricing structure, and the level of customer support provided. Prioritise the most essential criteria for your business’s success and tailor your evaluation process accordingly.

Step 3: Identify Potential 3PL Partners

Conduct thorough research and create a comprehensive list of potential 3PL providers that align with your selection criteria. In addition to exploring online resources, seek recommendations from industry peers to identify reputable providers with a proven track record of success. 

Remember to review your shortlisted 3PL provider’s customer testimonials and success stories as part of your evaluation process. This will provide valuable insights into the experiences of their past and current clients, helping you gauge their performance and service quality.

Step 4: Request for Information (RFI)

Send a Request for Information (RFI) to the shortlisted 3PL providers. The RFI should include essential details about your business, logistics requirements, and expectations. This step helps you gather preliminary information from potential providers and assess their ability to meet your needs. 

Remember, this is also an important step for 3PL partners. A full Request for Proposal (RFP) process requires significant effort and resources. By initiating the relationship with an RFI, you’re signalling your genuine interest in collaboration. This way, you ensure that you’re only moving forward with 3PL partners you can truly envision a successful partnership with, making the subsequent RFP process more meaningful and efficient.

Step 5: Request for Proposal (RFP)

Based on the responses from the RFIs, select a smaller group of 3PL providers and send them a Request for Proposal (RFP). The RFP should provide more detailed information about your business’s logistics requirements, including volume projections, service level expectations, technology integration needs, and other relevant details. The RFP process allows you to gather comprehensive proposals from potential providers and compare their offerings in detail. At this phase, it’s typical for 3PL providers to seek an in-person or virtual meeting. This allows them to clarify any queries, ensuring their responses to your RFP are as accurate as possible. Therefore, allocating sufficient time to meet with all the shortlisted providers is crucial.

Additionally, it’s worth noting that some companies may choose to require a Non-Disclosure Agreement (NDA) before sharing detailed information in the RFP to add a layer of confidentiality to the process and ensure that sensitive business information remains protected.

Step 6: Evaluate Proposals

Thoroughly review the received proposals from the shortlisted 3PL providers. As you assess the proposals, it’s vital not only to evaluate how well their offerings align with your selection criteria and business needs but also to consider the synergy between your companies. Pay attention to providers who exhibit a profound comprehension of your industry and put forth solutions tailored to address your distinct challenges.

While assessing the proposals, take into account factors beyond technical capabilities. Consider the compatibility of working methods and the team you’ll collaborate with. Flexibility in processes, account management approach, and team dynamics can significantly impact the success of the partnership. Additionally, weigh the sustainability of the business. Opting for a 3PL partner that prioritises sustainability, aligns with responsible business practices, and contributes positively to your brand’s image

Step 7: Site Visits and Due Diligence

As part of your evaluation process, visiting the facilities of your shortlisted 3PL providers is highly recommended. This will give you a firsthand look at their operations, technology infrastructure, and overall capabilities. A site visit is an excellent opportunity to gain insights into their operational aspects and interact with the team you’ll collaborate with daily.

During site visits, engage with the provider’s team and ask detailed questions to understand their processes comprehensively. Take this opportunity to further your due diligence efforts by delving into matters such as their financial stability, compliance with industry regulations, and their track record with clients. This thorough assessment will ensure that the 3PL provider aligns with your immediate needs and your long-term business objectives.

Step 8: References and Case Studies

Gather references and examine case studies from all potential 3PL providers. Reviewing case studies can offer valuable insights into their track record, customer satisfaction level, and capacity to uphold commitments. Furthermore, don’t hesitate to request the opportunity to communicate with their existing clients directly. This comprehensive approach to reference checking ensures a well-rounded understanding of the provider’s capabilities and helps you make a more informed decision

Step 9: Decision and Contract Negotiation

Based on your evaluations, choose the 3PL provider that best aligns with your business’s needs and goals. Once selected, engage in contract negotiations to finalise terms, pricing, service level agreements, and any other applicable details.

Step 10: Seamless Transition

After signing the contract, collaborate closely with your selected 3PL provider to facilitate a seamless transition of your logistics operations. Effective communication, collaboration, and well-defined expectations will form the foundation of a successful partnership. To ensure a smooth transition, consider engaging with your dedicated onboarding or project manager to develop a comprehensive transition timeline. This strategic approach enhances coordination and minimises disruptions, allowing you to navigate the shift smoothly and continue delivering top-notch service to your customers.


In conclusion, tendering for a new 3PL supplier is a strategic process that requires thorough planning, evaluation, and decision-making.
