A traditional 3PL RFP consumes two quarters and mostly measures a provider’s proposal-writing department. Meanwhile the operational facts that decide whether your inventory is safe — insurance limits, inventory accuracy, dock discipline, financial stability — can be verified in about ten business days by anyone willing to ask for documents instead of essays. The sequence below is the compressed vet: what to collect, what to walk, and what to pilot.
Days 1–2: the document pull
Request these in one email. The speed and completeness of the response is itself a data point.
- Certificate of insurance showing warehouse legal liability — check the per-occurrence limit against your maximum value at risk in the building, and confirm the policy term covers your engagement.
- W-9, years in operation, and two trade references with net-30 or longer terms — a provider that pays its own vendors on terms is a provider a landlord and a labor market trust.
- Certifications claimed: food-grade (AIB/BRCGS audit scores, not just registration), FDA registration numbers, hazmat permits, C-TPAT/FTZ where relevant. Verify registration numbers against the issuing body — it takes minutes.
- A live inventory accuracy report from their WMS: cycle count results for the trailing quarter. Ask for the report as generated, not retyped into a slide.
Days 3–5: the site walk
One hour on the floor tells you more than forty pages of proposal. Walk it with an operations person, not a salesperson, and look at leading indicators:
- Housekeeping: swept aisles, no broken pallets staged in rack, stretch wrap debris controlled. Floors are the cheapest honest signal in logistics.
- Rack condition: upright damage, missing safety clips, absent load-capacity placards — each one predicts how they will treat your product.
- Dock ratio and yard: doors per 10,000 sq ft (1 per 8–12k is typical for distribution), trailer staging space, whether inbound is appointment-run or free-for-all.
- Labeling discipline: every rack location barcoded and legible; staged pallets carry license plates. If you see handwritten location tags, the WMS demo was theater.
- People: ask a reach truck operator how long they have worked there. Turnover shows up in the answer before it shows up in your order accuracy.
Days 6–8: SLA terms that actually bind
Skip the service-philosophy language. Nail numbers with remedies:
- Dock-to-stock: inbound received and putaway inside 24 hours (48 for floor-loaded containers), measured from dock stamp.
- Inventory accuracy: ≥99.8% by location on cycle counts, full physical annually, shrink allowance defined in basis points with a make-good above it.
- Order accuracy: ≥99.5% lines shipped clean; mis-ships re-shipped at the 3PL’s freight cost.
- Reporting: your inventory visible to you in something close to real time — portal or feed — not a Friday spreadsheet.
- Exit terms: 60–90 day termination without cause, transfer assistance priced in advance. The easiest partner to sign with is the one who makes it easy to leave.
Days 9–10: structure a paid pilot instead of a longer negotiation
- 50–100 pallets, 30–60 days, full rate card — a free pilot produces free-pilot effort.
- Define the three metrics that decide expansion (dock-to-stock, order accuracy, invoice accuracy) and the thresholds in writing before the first truck.
- Audit the pilot invoices line by line against the rate card. Billing discipline in week three predicts billing discipline in year three.
Red flags that end the conversation
- COI arrives slowly, from a broker you cannot verify, or with limits that shrink on inspection
- No cycle count program — “we do an annual physical” means they discover shrink once a year
- Rate card resists itemization: handling, storage, and accessorials blended into one number
- The reference customers are all under 12 months old
- You are not allowed on the floor unannounced during the pilot
Warehouse Atlas front-loads the paperwork stage of this vet — insurance and WMS documentation are collected before a facility enters the grid, so requests route to operations that already cleared the first gate. Route a request or read how to decompose the storage quote they send back.
