How To Complete a 3PL Intake Form: A Merchant Checklist

3PL Intake Form A form used to collect a merchant’s products, volume, channels, service needs, locations, and operational requirements. Treat it as an operational checklist: the information you provide drives slotting, labor, system setup, and commercial terms.

Completing a 3PL intake form efficiently reduces onboarding time and avoids scope gaps that produce surprise fees later. This article is a pragmatic checklist merchants can use while filling out an intake form — which fields to prioritize, what supporting files to attach, and the common pitfalls that delay integration.

Pre-Work Before You Start

• SKU Master File: Prepare a CSV with SKU, UPC/GTIN, unit dimensions, weight, and pack quantities.
• Volume Forecast: Create a 12-month forecast with expected peaks and new product introductions highlighted.
• Channel Specs: Collect any retailer or marketplace compliance docs (label templates, ASN rules, EDI specifications).
• Order Sample: Export a sample order file from your commerce platform to validate mapping.

Field-By-Field Checklist

Below are the intake form sections and the practical answer merchants should prepare:

• Product Details: Provide exact dimensions (L×W×H), weight, berth/unit of measure, and inner/outer pack counts; include photos for irregular cartons.
• Forecast & Peaks: Include average, minimum, and maximum weekly units; note pre-order campaigns and promotional spikes.
• Order Flow: Specify order cutoff times, preferred pick/pack rules (FIFO, LIFO, FEFO), order transmission method, and required confirmations.
• Packaging & Kitting: State whether you supply packaging or need the 3PL to provide it; outline kitting frequency and instructions.
• Returns: Define return reasons, inspection thresholds, restock policies, and disposition routes (refurbish, recycle, destroy).
• Compliance: List certificates for regulated goods, temperature ranges for cold-chain items, and hazardous material identifiers.

Supporting Documents To Attach

• Label Templates: Examples of customer-facing packing slips, carrier labels, and marketplace-specific labels.
• ASN/EDI Samples: A sample ASN or EDI 850/940 file — or API docs if you’ll use JSON/XML order transmission.
• Process Map: One-page diagram of order-to-delivery and returns workflows to clarify responsibilities.
• Packaging Specs: Photos or diagrams showing tray, carton, or palletization patterns for freight planning.

Common Pitfalls And How To Avoid Them

Merchants often leave ambiguous descriptions, underestimate peaks, or omit exceptions. Avoid these by:

• Being Specific: Replace “assorted items” with SKU-level entries; provide dimensions and pack counts for each SKU.
• Highlighting Exceptions: Call out fragile, oversized, or regulated SKUs in a dedicated section.
• Confirming Timelines: Include target go-live date and any blackout periods for testing or launches.

How The 3PL Uses Your Answers

Answers populate three downstream activities: commercial (pricing and contracts), technical (WMS/TMS mappings), and operational (slotting and labor plans). Clear inputs shorten the technical configuration window and reduce change orders after go-live.

Checklist Example — Minimum Viable Answers

• SKU File: 100% of active SKUs with dimensions and weights.
• Forecast: Monthly expected ship units for the next 12 months with peak week highlighted.
• Order Method: API push, with sample JSON payload attached.
• Returns Policy: 30 days, inspection threshold 95% restockable.

In short, the 3PL Intake Form is a structured checklist. Treat it as an operational handover packet: prepare SKU data, forecast, channel specs, and process maps ahead of time to accelerate onboarding and avoid downstream surprises.
