Contracted Warehouse: 3PL Site, SLA and Inventory-Custody Controls

A Contracted Warehouse Is a Managed Service

The SSDER glossary defines ANLAŞMALI DEPO as a warehouse contracted for one or more customers. In procurement, this is a service boundary: the buyer is purchasing space, people, equipment, systems, processes and custody. The right comparison is total landed and operating cost at the promised service level, not a single storage tariff.

Start with the flow and the risk. State inbound appointment, unloading, count, inspection, put-away, replenishment, picking, packing, value-added work, dispatch, returns, cycle count and disposal. Identify which activities remain with the buyer, supplier, carrier, customs broker or warehouse operator.

Write the SLA Around Customer Outcomes

An SLA should define measurable outcomes such as appointment adherence, receiving turnaround, put-away time, order accuracy, pick completion, dispatch cut-off, inventory accuracy, damage rate, response time and data availability. Include the measurement population, exclusions, clock, reporting deadline and remedy when performance misses.

Avoid a scorecard that rewards speed while hiding quality. A warehouse that closes receipts quickly but records wrong quantities creates downstream shortages and invoice disputes. Use a balanced set of service, evidence, safety, cost and improvement measures, with separate critical events for security, customs or regulated inventory.

Control Custody, Systems and Stock

Define when the warehouse becomes responsible for quantity, condition, security, temperature, seals and documents. Require item, lot, serial, expiry, location, status and handling-unit data to be exchanged through a controlled interface. Reconciliation should compare the warehouse ledger, buyer ERP, carrier proof and physical count.

Set cycle-count frequency and variance thresholds by risk. A high-value serialized part needs stronger evidence than a low-value consumable, while regulated or bonded stock needs the applicable legal controls. Require root-cause analysis, adjustment approval and a preserved audit trail for every material variance.

Security, Capacity and Continuity

The RFP should cover access control, visitor records, CCTV, key management, fire protection, pest control, equipment maintenance, cyber controls and incident notification. Ask how the operator protects stock during peak demand, power loss, labour shortage, weather disruption or a systems outage.

Define reserved and flex capacity, overflow rules, peak pricing, minimum volume, equipment ownership and subcontracting approval. Business continuity should identify an alternate site, data backup, emergency contacts, recovery time and the evidence needed to move stock without losing custody.

Worked Example: A Cheap Pallet Rate

A warehouse offers a low pallet-month price but excludes unloading, cycle counts, labelling, peak overflow and after-hours dispatch. The buyer awards the site, then pays accessorials and discovers that a systems outage delays a production line. The contract has no service credit or stock-transfer process.

The corrected sourcing event prices a standard activity basket, peak scenarios and exit costs. The agreement defines data, custody, SLA, insurance, incident response and alternate capacity. Bids are compared on cost per accurate order and total operating risk rather than storage rent alone.

Metrics and Governance

For contracted warehouse procurement controls, measure both service and evidence quality. Useful indicators include first-pass acceptance, exception rate, response time, unplanned cost, document completeness, damage or discrepancy rate, and the percentage of shipments that follow the approved process. A dashboard should distinguish a supplier failure from a carrier, terminal, broker or internal master-data failure.

Review the metric trend with procurement, logistics, finance, quality and the responsible specialist. Use a monthly exception sample to test whether the control worked in a real transaction, not just whether a field was filled. Repeated exceptions should change the sourcing strategy, contract, lane design or supplier development plan.

Keep the control proportionate to risk. High-value, regulated, time-critical or safety-sensitive cargo needs stronger evidence and faster escalation than a routine shipment. Record the decision owner, approval date, source documents and follow-up action so the next buyer can understand the operating history.

Supplier and Carrier Questions

• Which ANLAŞMALI DEPO or related glossary condition is assumed in your quotation, procedure or service description?
• Which party owns each data field, physical handoff, inspection, document and exception?
• What evidence will be available before release, loading, movement, receipt, invoice approval or claim?
• What changes require advance notice, requalification, a revised price or a new risk decision?
• How will the supplier report incidents, delays, mismatches and corrective actions, and within what response time?

Implementation Sequence

Implement the control in a small, representative lane first. Capture the baseline process, test the required data and evidence, run a real transaction, and review every exception with the people who performed the work. Do not declare the control effective only because a supplier signed a procedure.

After the first three shipments or operating cycles, update the purchase-order clause, work instruction, scorecard and training. Scale the control to other suppliers only when the evidence is repeatable and the owner can explain what happens when the normal path fails.

Common Mistakes to Avoid

• Buying pallet space without defining the warehouse process and custody boundary.
• Using percentages without stating the SLA clock, exclusions, sample and remedy.
• Allowing stock adjustments or subcontracting without approval and audit evidence.
• Ignoring peak, outage, security, insurance, customs and business-continuity needs.
• Leaving termination and stock-transfer costs until the relationship is already failing.

Procurement Implementation Checklist

• Map inbound, storage, value-added, outbound, return and disposal activities.
• Define custody, inventory, security, quality, temperature and document responsibilities.
• Set SLA clocks, exclusions, reports, remedies and critical-event escalation.
• Specify WMS/ERP interfaces, master data, counts, adjustments and audit retention.
• Price peak capacity, accessorials, insurance, continuity and subcontracting controls.
• Test a transition-in and transition-out plan before signing the term.
