What Should Be in an SLA for Order Fulfillment?

Katherine Wroth • June 26, 2024

At Barrett Distribution Centers, we know that not all SLAs are created equal. When partnering with a 3PL provider for order fulfillment services, a well-designed Service Level Agreement (SLA) is your blueprint for success. A strong SLA sets the stage for a productive and transparent relationship, ensuring both parties understand their roles and responsibilities. It also serves as a benchmark for evaluating the performance and effectiveness of the 3PL provider, promoting continuous improvement and accountability.


What exactly is a Service Level Agreement (SLA)?


A Service Level Agreement (SLA) ensures that all parties involved in order fulfillment are on the same page. An SLA is a formal contract between the 3PL provider and a client that outlines the specific services expected, the standards to be maintained and the metrics for measuring performance. At Barrett, we pride ourselves on providing personalized logistics solutions; having a well-defined SLA is key to maintaining trust and client satisfaction.


Here’s a comprehensive guide on what should be included in an SLA for order fulfillment:


  • Service Description: The first element of an SLA is a clear and detailed description of the services provided. This should cover all aspects of order fulfillment, including receiving orders, processing, picking and packing, shipping and handling returns. It should specify the scope of services and any limitations. This clarity helps set the right expectations and ensures there are no ambiguities.


  • Performance Metrics: Performance metrics are the backbone of any SLA. They define how the 3PL provider’s performance will be measured and reported. For order fulfillment, common metrics include:
  • Order Accuracy: The percentage of orders correctly fulfilled without errors.
  • On-time Delivery: The percentage of orders delivered within the agreed timeframe.
  • Inventory Accuracy: The accuracy of stock levels as reported in the inventory management system.
  • Return Processing Time: The time taken to process returned items and update inventory.


  • Responsibilities of Each Party: An SLA should clearly delineate the responsibilities of both the 3PL provider and the client. The 3PL provider's responsibilities may include ensuring timely order processing, maintaining accurate inventory records and providing regular performance reports. The client’s responsibilities may include providing accurate order information, timely payments and adhering to agreed-upon procedures for returns and disputes.


  • Issue Resolution and Escalation Procedures: Despite the best efforts, issues can arise. An SLA should include detailed procedures for resolving problems and escalating unresolved issues. This section should outline the steps to be taken during service failures, including who to contact, the timeframe for resolution, and how issues will be documented and reported. A clear escalation path helps quickly address and mitigate issues before significantly impacting the business.


  • Service Availability and Support: This section should specify the availability of services and support. For example, it should detail the operating hours, availability of customer support and any provisions for after-hours or emergency support. This ensures clients know when to expect assistance and what support is available.


  • Compliance and Security Standards: Order fulfillment often involves handling sensitive information, such as customer and payment information. The SLA should outline the compliance and security standards to which the 3PL provider will adhere. This may include compliance with regulations like GDPR or CCPA, data protection and cybersecurity standards.


  • Performance Reporting: Regular performance reporting is crucial for transparency and accountability. The SLA should specify the frequency and format of performance reports. These reports should provide insights into key metrics, any service issues encountered and steps taken to resolve them. This helps maintain a transparent relationship and enables continuous improvement.


  • Penalties and Incentives: To ensure adherence to the SLA, it’s common to include penalties for non-compliance and incentives for exceeding performance expectations. Penalties might include financial compensation for missed targets, while incentives could be bonuses for consistently meeting or exceeding service levels.


  • Managing Capacity for Growing E-commerce Businesses: Many of our e-commerce clients are experiencing significant growth. Are you prepared to manage new markets and increase sales? When collaborating with your 3PL partner, it’s essential to consider how rising order volumes will affect your SLAs. Understanding your 3PL’s ability to scale alongside your growth while maintaining your brand promise is critical in your decision-making process.

If you’re evaluating third-party logistics (3PL) partners, the #1 tip is simple: Go on-site. A site visit will tell you more in 15 minutes than any sales presentation ever will — and it can save you months of operational pain down the road. While on-site, here are the top three things you should be doing: 1. Meet the people doing the work Start with the people — not the slides. Meet the operators on the floor Talk to the warehouse managers Ask questions directly to the people picking, packing, and shipping orders You’ll learn quickly whether the team truly understands the operation or is just following a script. A strong 3PL isn’t just systems and software — it’s experienced people who care about execution. Bonus tip: Spend time with the general manager . Their visibility, accountability, and involvement matter more than most brands realize. 2. Pay attention to cleanliness and organization This one is underrated — and incredibly telling. Are aisles clearly marked? Is inventory organized and easy to locate? Are workstations clean and efficient? Pro tip: Check the bathrooms 👀 If shared spaces are clean and well-maintained, chances are the same standards apply to inventory, orders, and overall service. 3. Watch how orders actually move through the building Don’t just ask how fulfillment works — watch it happen . How do orders flow from receiving to storage to pick, pack, and ship? Are there bottlenecks? Is automation helping or slowing things down? Do employees seem confident in the process? This is where reality separates itself from the pitch deck. What looks great on paper can fall apart in motion, and a live walkthrough makes that obvious fast. Why a site visit matters more than any deck A 3PL can show you metrics, technology screenshots, and polished case studies. But only a site visit shows you: Culture Execution Attention to detail How issues are handled in real time That firsthand perspective can prevent misalignment, missed expectations, and painful transitions after go-live. The bottom line If you’re choosing a 3PL partner, don’t skip this step. Go on-site. Meet the people. Watch the operation. It’s the fastest way to validate your decision — and one of the smartest moves you can make before signing a contract. Interested in booking a visit to one of Barrett's facilities?

Warehouse automation isn’t new, but determining when it actually makes sense is where most companies struggle. Recorded live at WERC 2025 in New Orleans, this conversation brings together leaders directly involved in real-world warehouse automation decisions. Kevin Lawson interviews Chris Lingenfelter , founder of Robot Advisors, and our very own Tim Barrett , CEO of Barrett Distribution Centers. They sit down for a practical discussion on robotics, drones, and the hype surrounding automation. The focus stays on what actually matters: cost per unit, operational fit, employee experience, and ROI. If you’re evaluating warehouse automation or wondering why past investments haven’t delivered, this breakdown offers practical, experience-backed insights. Why Barrett took a robot-agnostic approach One of the most important takeaways from the WERC session: there is no one-size-fits-all robot. Barrett was an early adopter of autonomous mobile robots (AMRs), including systems from Locus Robotics and Six River Systems. But instead of standardizing on one solution, the company evaluates automation based on: SKU count and product size Order profiles and velocity Facility layout Customer growth expectations A footwear operation with serialized inventory has very different needs than an apparel fulfillment center, and Barrett treats them that way. The result: better outcomes for customers and lower long-term operational risk. Inventory drones: the unexpected game changer While AMRs get the spotlight, Barrett’s biggest automation win came from inventory drones. Using drone-based cycle counting, Barrett increased inventory count frequency by more than 7x while significantly reducing labor costs. For high-accuracy environments, especially serialized footwear inventory, this technology proved essential. The impact went beyond numbers: Higher inventory accuracy Faster exception resolution Better employee roles focused on analysis instead of manual counting In short, automation didn’t eliminate jobs. It made them better. How Barrett really thinks about ROI ROI isn’t ignored, but it isn’t the only metric. Barrett evaluates automation using cost per unit shipped rather than chasing flashy payback models. Capital investments are amortized based on contract life and redeployment potential, then layered with labor and operating costs. The guiding question is simple: Which solution produces the lowest sustainable cost per unit? That approach keeps decision-making grounded and aligned with customer outcomes, not tech hype. “To bot or not” starts with a baseline Chris Lingenfelter, founder of Robot Advisors, reinforced a critical point during the session: You can’t evaluate automation if you don’t understand how your warehouse operates today. Many companies struggle to answer basic questions: What does each unit really cost to ship? Where are labor inefficiencies hiding? Which processes are already working well? Before recommending automation, Robot Advisors helps operators establish a true baseline, then compare technologies objectively. Sometimes, the right answer isn’t robotics at all. That honesty matters. Automation as a competitive advantage for 3PLs For Barrett, automation isn’t just an operational tool. It’s a competitive differentiator. When engaging new prospects, the team often presents: Multiple automation paths Clear tradeoffs between solutions A data-backed rationale for each option That depth of analysis resonates with COOs and CFOs evaluating long-term fulfillment partners. It signals preparedness, transparency, and experience, not guesswork. The workforce question: what changes, what doesn’t As robotics adoption increases, warehouse roles are evolving. At Barrett, automation shifted labor away from repetitive tasks and toward: Exception management System oversight Data analysis Engineering and IT support Over time, this required growing centralized IT and engineering teams, a necessary investment to support advanced operations across multiple facilities. The takeaway from WERC 2025 was clear: automation changes work. It doesn’t eliminate the need for people. Thinking about automation, but not sure where to start?
