Fulfillment SLA Tracking: Why Service Promises Only Matter If They Are Measured

Service level agreements sound reassuring when contracts are signed. Same-day shipping, fast receiving, and high accuracy all look good on paper. The problem is that SLAs only protect a business when they are actively tracked. This is why fulfillment SLA tracking matters for brands that care about execution instead of assumptions.

Without tracking, SLAs become after-the-fact explanations instead of tools for managing performance in real time.

Why SLAs Fail Without Measurement

Many brands assume their SLAs are being met until something breaks. Orders ship late, inventory sits unreceived, or retailers escalate issues.

Maureen Milligan, Director of Operations and Projects at G10 Fulfillment, explains what customers expect. "A lot of the 3PL customer expectations are that order fulfillment is happening extremely timely, that our inventory is accurate, and that we're able to execute on their orders very quickly." SLA tracking makes those expectations visible instead of assumed.

What Fulfillment SLAs Actually Cover

SLAs go beyond shipping speed. They include receiving timelines, pick accuracy, pack accuracy, and B2B compliance execution.

Joel Malmquist, VP of Customer Experience at G10 Fulfillment, explains the scope. "An SLA is a Service Level Agreement for receiving, outbound, and B2B." Tracking each stage shows exactly where performance holds and where it slips.

Clean Data Is the Foundation of SLA Tracking

SLA tracking depends on accurate operational data captured in real time. Manual steps and delayed updates weaken reporting.

Bryan Wright, CTO and COO of G10 Fulfillment, explains why systems matter. "A good WMS tracks inventory through the warehouse at every point that you touch it," Wright says. "That is what allows us to measure performance accurately."

Real-Time SLA Tracking Prevents Escalations

When SLA performance is visible as work happens, teams can intervene before failures reach customers or retailers.

Connor Perkins, Director of Fulfillment at G10 Fulfillment, describes the benefit. "Our clients get best-in-class visibility and transparency. They can see their daily orders, they can see KPIs, and they can see historical transactions." That visibility allows issues to be addressed early.

Retail SLAs Raise the Cost of Failure

In retail fulfillment, SLAs are enforced with penalties instead of warnings. Missed windows lead to chargebacks or canceled orders.

Holly Woods, Director of Operations at G10 Fulfillment, explains the reality. "Target has a deadline for delivery and that's it, no exceptions. They'll just cancel the order." SLA tracking helps brands protect those relationships.

Tracking Builds Accountability on Both Sides

Shared SLA data improves conversations between brands and 3PLs. Performance discussions focus on facts instead of finger pointing.

Matt Bradbury, Director of Sales at G10 Fulfillment, connects transparency to confidence. "Transparency and predictability help us build trust." Clear SLA tracking aligns expectations on both sides.

Why Continuous SLA Tracking Beats Quarterly Reviews

Quarterly SLA reviews look backward, long after problems have already impacted customers. Continuous tracking focuses attention on what is happening now.

Milligan highlights the value of immediacy. "They can actually watch those progressions going on." That visibility allows teams to correct issues before SLAs are missed.

What Fulfillment SLA Tracking Really Delivers

Strong SLA tracking reduces surprises, protects retailer relationships, and keeps fulfillment predictable as volume grows. It turns service promises into measurable performance.

For growing brands, fulfillment SLA tracking is not about penalties or blame. It is about maintaining control as complexity increases.

The next step is simple. Choose a 3PL that tracks fulfillment SLAs in real time, so service levels are managed every day instead of debated later.
