10 questions you should ask on a 3PL site visit

Most brands arrive at a 3PL warehouse tour with no agenda, follow the scripted route, and leave without seeing what matters. The sales team has done this hundreds of times. You probably haven't. These questions are the ones a good 3PL partner will actually want you to ask, because a confident operation has nothing to hide.

1. How clean and organised is this facility?

Cleanliness isn't about aesthetics. It's a direct signal of process discipline. A well-run warehouse applies 5S methodology (Sort, Set in order, Shine, Standardise, Sustain) as a daily practice, not a pre-visit clean-up.

• Ask: "Is this the normal operating state?" and "Show me a corner you consider a work in progress."
  
  

• Observe: Corner areas, rack bottoms, aisle markings, unlabelled pallets. These are the parts that get skipped when someone's been told a client is coming.

Green flag: "You could visit unannounced any day and see the same thing."

Red flag: Significant advance notice was required, and the warehouse looks suspiciously clean.

2. Can you walk me through a real order being picked?

A live pick reveals more than any demo. It shows whether the warehouse uses scan-verified processes or paper-based picking. Paper pick lists are uncommon in modern 3PLs, but obviously represent a real accuracy risk.

• Ask: "Can I watch a picker process a live order?" and "What picking methodology do you use: wave, zone, or batch?"
  
  

• Observe: Whether the worker scans at every step and whether packing instructions are visible at the station.
  
  

• Benchmark: Picking error rates by method run roughly 1 to 2% on paper, 0.1 to 0.3% with scan-verified systems, and below 0.01% with vision-assisted picking.

Green flag: Scanning at every handoff; packing instructions posted at each station.

Red flag: Paper pick lists; a worker who pauses and checks with a supervisor mid-pick.

3. How frequently do you conduct cycle counts, and can I see the log?

Daily or ABC-based cycle counting is the standard for maintaining 99.5%+ inventory accuracy. ABC counting prioritises your inventory by value and velocity: A-items are your fastest-moving or highest-value SKUs and get counted most frequently, B-items less so, and C-items least often. It means errors get caught quickly where they matter most.

• Ask: "What's your methodology: ABC, random, or full count?" and "Can I see the most recent report?"
  
  

• Benchmark: A-items (your fastest-moving SKUs) should be counted weekly, B-items monthly, C-items quarterly. Best-in-class accuracy sits at 99.9%.

Green flag: A-B-C cycle count programme in place; log available on request; clients have real-time access via a Warehouse Management System (WMS) dashboard.

Red flag: "We do a full physical count once a year." No log available or offered.

4. What's your dock-to-stock time, and what happens when a shipment arrives late?

Every hour inventory sits unprocessed on a receiving dock is inventory you can't sell, can't allocate, and can't account for. Dock-to-stock time is a basic operational health metric, and most 3PLs track it.

• Ask: "What's your average dock-to-stock time, and do you have historical data?" and "What's the procedure when a carrier misses the receiving window?"
  
  

• Observe: Receiving dock organisation; whether incoming inventory is labelled and separated by client; any visible backlog of unprocessed pallets.
  
  

• Benchmark: Target under 24 hours. Above 48 hours is a material concern.

Green flag: Historical data available on request; a documented missed-window procedure with client notification built in.

Red flag: "It depends on the volume" with no supporting data to back that up.

5. Can I see a live demo of your WMS and the client dashboard?

A live pull-up on an operational screen tells you more than a polished sales demo. You want to see what your daily visibility actually looks like, not a curated walkthrough prepared the night before.

• Ask: "Pull up a client dashboard right now." "Is the data real-time or is there a reporting lag?" and "Does the system have an open Application Programming Interface (API) for integrations?"
  
  

• Observe: How fast the system loads, whether the interface looks like it was built in the last decade, and whether the operator navigates it confidently or needs coaching.

Green flag: Dashboard up in under 60 seconds; the operator moves through it without prompting.

Red flag: "The system is being updated" or "That would be a separate demo."

6. What percentage of your workforce is permanent vs. temporary, and how does that change in Q4?

Heavy reliance on temporary workers during peak season means untrained hands are processing your most critical orders at your highest volume. That's where errors compound.

• Ask: "What's your permanent-to-temporary ratio?" "How many temps do you bring on for Q4, and what does onboarding look like?" and "What's your current staff turnover rate?"
  
  

• Observe: Ask a warehouse associate directly how long they've worked there. One question, unprompted, tells you a lot.

Green flag: Core operations are 80%+ permanent staff; temporary workers complete a structured two-day onboarding before touching live orders.

Red flag: "We scale to 80% temporary in Q4" with no described training protocol.

7. How do you handle peak season, and what happened last Q4?

Generic reassurances about peak readiness aren't useful. Ask specifically about last Q4. An inability to cite real performance data is disqualifying.

• Ask: "What was your order accuracy rate last Q4?" "Did you hit all Service Level Agreement (SLA) commitments?" and "Can I see the labour planning board?"
  
  

• Observe: Whether documented peak processes are visible on the warehouse floor: labour boards, overflow plans, carrier cut-off schedules. Prepared operations teams post these.

Green flag: Specific Q4 data; a documented capacity plan; a candid account of a problem that was caught and corrected.

Red flag: "We never have issues at peak" with no data to support it.

8. What's your shrinkage policy, and what's your historical rate?

You need the historical rate before the contract defines what you'll be expected to absorb. A 3PL that can't produce shrinkage data doesn't have a good reason for that.

• Ask: "What's the contractual shrinkage allowance?" "What's the actual rate over the last 12 months?" and "What's the investigation and reporting process when shrinkage is identified?"
  
  

• Observe: Security camera coverage, access-controlled storage for high-value items, and general facility access controls.
  
  

• Benchmark: Industry average sits at 1.44%. Contractual allowances typically run between 0.5% and 1%. Best-in-class operations come in below 0.2%.

Green flag: Historical data available; rate below 0.5%; a clear, documented investigation process.

Red flag: "Shrinkage happens, it's in the contract." No data offered.

9. What happens when something goes wrong, and can you walk me through a recent problem?

Every 3PL makes mistakes. The question isn't whether errors happen. It's whether the operation detects them quickly, communicates honestly, and resolves them with a documented process.

• Ask: "Describe a fulfilment error from the past six months." "What's the escalation path, who contacts the client and when?" and "What's the claims process for damaged inventory?"
  
  

• Observe: Whether a visible escalation or complaint board exists on the floor; whether operations team members answer your questions directly or defer everything to the sales rep.

Green flag: A candid example with a clear resolution timeline; a named escalation contact, not just "our support team."

Red flag: "We don't really have issues" or an escalation path that ends with "email support."

10. Can I speak with one of your warehouse employees, without a manager present?

This is the most underused question on any site visit, and the most revealing. A 3PL's hesitation to allow it tells you as much as the conversation itself.

• Ask the employee: "How long have you worked here?" "What would you change about the operation?" "How do you find out when there's a problem with an order?" and "What's training like?"
  
  

• Observe: Eye contact, confidence, whether the employee answers freely or looks for approval before responding.

Green flag: Long-tenured staff; direct, confident answers.

Red flag: Hesitation or refusal from management; employees who deflect all questions back to the team leader.

FAQs

How long should a 3PL site visit take?

Two to three hours minimum. Allow at least 30 minutes on the warehouse floor, 30 minutes on a WMS demo, plus time with operations leadership and a direct conversation with a floor associate. Remember: you're entrusting this 3PL with a brand or business you've been working on for years. Take as long as you need.

Should I visit before or after signing a contract?

Always before. The visit is due diligence, not a formality. Signing first and visiting second removes your best leverage.

Is it acceptable to arrive early or unannounced?

Schedule the tour, but consider arriving 30 to 60 minutes early. Alternatively, request a second visit with minimal notice after the formal tour.

What documents should I ask for?

The SLA with KPIs, a sample client reporting dashboard, recent cycle count reports, Q4 performance data, and at least three client references in a similar product category to yours.

How many facilities should I visit?

At least two or three. Comparison visits sharpen your instincts and give you context for what good actually looks like, which also helps in contract negotiations.

What to take away from a site visit

A well-run 3PL has nothing to hide. The cleanliness you see on a random Tuesday predicts operational discipline better than any sales presentation. Scan-verified picking, active cycle counting, and dock-to-stock times under 24 hours are the minimum standards you should be looking for.

Staff tenure and a willingness to let you speak with employees privately are culture signals. Q4 data is the real test of any fulfilment partner's capabilities. And shrinkage below 0.5% with inventory accuracy above 99.5% should be in your contract, not left as aspirational targets.

If a 3PL can answer these questions with data, candour, and a live demonstration, that's a partner worth talking to seriously. If they can't, you've saved yourself a painful discovery further down the line.
