How To Draft a Delivery SLA: Clauses, Metrics, And Sample Rules

A service-level agreement defining delivery speed, attempt rules, communication, proof of delivery, or performance expectations.

Delivery SLA A service-level agreement defining delivery speed, attempt rules, communication, proof of delivery, or performance expectations. Drafting an SLA turns business objectives into operational language that carriers, warehouses, and customer service teams can execute against.

Start drafting with a clear scope: which SKUs, regions, and services the SLA applies to. Different products (fragile, hazardous, temperature-controlled) and destinations (residential, commercial, rural) need different rules. Use precise verbs and measurable targets so operations can automate compliance and reporting.

Must‑Have Clauses

Include clauses that remove interpretation gaps and provide actionable steps when exceptions occur.

• Service Scope: Define the covered SKUs, geographic zones, and excluded items (e.g., hazmat, oversized).
• Transit Commitments: State transit windows, cut-off times, and whether transit is business-day or calendar-day based.
• Attempt And Delivery Rules: Specify number of attempts, allowed delivery methods (leave at door, neighbor, signature required), and driver authority levels.
• Communication Standards: Required notifications, tracking update frequency, and exact text or data fields that must be supplied to customers and shippers.
• POD And Evidence: What constitutes proof (signature, photograph, GPS), storage duration for records, and format for exchange.
• Exceptions And Escalation: Force majeure, weather, customs delays, plus required notifications and escalation timelines.

Metrics And Measurement

Define how success is measured and who provides the data.

• On‑Time Delivery: Percentage delivered within the SLA window. Define timestamp sources and timezone normalization.
• First‑Attempt Delivery Rate: Percentage delivered on first driver visit.
• Claims Rate: Frequency of loss or damage claims per thousand shipments.
• POD Availability: Percentage of deliveries with acceptable proof retained within the agreed retention period.

Sample Attempt Rules (Operational Language)

Operational wording reduces ambiguity in day-to-day execution. Include explicit timing and actions.

• First Attempt: Driver will attempt delivery between 08:00–18:00 local time; if no answer, driver leaves a printed notice and retries within 24 hours.
• Second Attempt: If second attempt fails, driver will take POD photo and return shipment to local hub for disposition per shipper instructions.
• Signature Policy: High-value items >$500 require recipient signature; otherwise photo or scan is acceptable.

Billing, Penalties, And Service Credits

Make the financial consequences explicit to enforce the SLA. Decide whether failed deliveries incur credits, chargebacks, or corrective actions. Tie the penalty structure to measurable KPIs and a defined remediation process.

• Service Credits: Percentage of shipping fees refunded for missed delivery windows beyond agreed tolerance.
• Chargebacks: Fees applied for incorrect handling (e.g., failure to follow signature requirement) documented with POD evidence.
• Remediation: Action plans required for persistent breaches, including root-cause analysis and timelines for improvement.

Who Signs And Operationalizes The SLA

SLAs should be signed by commercial and operations leads from both parties. After signing, translate SLA items into operational standards: TMS rules, WMS pick priorities, driver manifests, and customer notifications. Maintain a living document and schedule quarterly reviews to adjust for volume changes or seasonal peaks.

Tips For Negotiation

• Start With Data: Use historical transit and delivery attempt data to set realistic targets.
• Build Tiered Options: Offer multiple SLA tiers (standard, expedited, premium) with clear pricing.
• Agree On Dispute Resolution: Define timelines and an evidence package (POD, timestamps) required to resolve disputes.
• Include Exit Criteria: Conditions under which either party can terminate or renegotiate the SLA without penalty.

In short, the Delivery SLA should contain explicit clauses for scope, transit times, attempts, communication, POD, metrics, and penalties. Drafting with operational precision ensures teams can automate compliance, measure performance, and resolve disputes quickly.
