The right 3PL should fit your products, order profile, technology, customer locations, and growth plan—not simply offer the lowest pick-and-pack rate. Ecommerce brands should evaluate operational fit, warehouse coverage, service levels, systems, pricing, global shipping, returns, scalability, and support before signing a contract.
Use this checklist to compare providers consistently and identify risks before transferring inventory.
1. Confirm Product and Channel Fit
Give every candidate the same operating profile:
- Monthly and peak order volumes
- SKU count, dimensions, weights, and storage needs
- Average units and lines per order
- DTC, marketplace, wholesale, and subscription mix
- Packaging, kitting, labelling, and inspection requirements
- Return volume and disposition rules
Ask whether the provider regularly handles products and channels similar to yours. Cosmetics, electronics, fragile items, bundles, or serialised products may require different storage, packing, inspection, and documentation procedures.
A capable provider should explain the workflow rather than simply say it can handle the category.
2. Evaluate Warehouse Locations and Inventory Strategy
Warehouse location affects transit time, transportation cost, inventory allocation, and returns. Compare each facility with the geographic distribution of your customers.
A multi-warehouse network can shorten delivery distances, but splitting inventory creates forecasting challenges. Your team must decide which SKUs belong in each location and how replenishment works.
Ask:
- Which facility will store each SKU?
- Can orders be routed by destination and stock availability?
- How are warehouse transfers priced and tracked?
- Can the network support domestic and cross-border orders?
- Is local return processing available in key markets?
Choose a network that supports demand without creating unnecessary inventory duplication.
3. Review 3PL Order Fulfillment Standards
The proposal should explain how orders move from receipt to dispatch. Request written commitments for order cut-off times, processing speed, receiving turnaround, inventory accuracy, and exception handling.
Confirm how each metric is calculated. Ask when the dispatch clock starts, which orders are excluded, how errors are recorded, and how often reports are provided.
Useful questions include:
- What happens when an item is missing, damaged, or mislabelled?
- How are service failures investigated?
- Are reports available by location and channel?
- What corrective action follows repeated errors?
Compare service levels, operating evidence, technology, and facility quality alongside price.
4. Compare the Complete Pricing Structure
A low fulfillment rate may be offset by receiving charges, storage minimums, packaging markups, integration costs, returns, peak surcharges, and special-project labour.
Request a complete rate card and a sample invoice based on your data. Model an average month, a low-volume month, and a peak month.
Check for:
- Setup and onboarding
- Receiving and inventory counts
- Storage and ageing rules
- First-item and additional-item fees
- Packaging materials
- Kitting, inspection, and relabelling
- Returns and disposal
- Monthly minimums and peak surcharges
- Freight, postage, and fuel adjustments
- Renewal and termination costs
Compare the fully loaded monthly total rather than one headline rate. Pricing reviews should also address storage overages, rush work, and platform-access fees.
5. Assess Global Shipping Capabilities
Global shipping requires more than carrier access. A provider may need to coordinate customs data, export documents, duties and taxes, restricted-product rules, tracking, delivery exceptions, and international returns.
Ask which destinations and service levels are supported, whether duties can be prepaid, how landed costs are communicated, and who handles customs-related problems. Review the available options for individual parcels, bulk freight, marketplace replenishment, and urgent orders.
Brands sourcing in China should also ask whether products can be inspected, labelled, packaged, and dispatched near the factory. Earlier checks can identify product or packaging problems before inventory travels internationally.
6. Examine Returns and Value-Added Services
Returns need a documented workflow. Ask how products are received, inspected, graded, restocked, quarantined, refurbished, or disposed of. Confirm when inventory records and customer-facing data are updated.
Review services that may become important later:
- Kitting and bundle assembly
- Branded packaging and inserts
- Barcode and label verification
- Quality inspections
- Amazon FBA preparation
- Wholesale compliance projects
Confirm capacity, turnaround times, instructions, and pricing. A service being listed does not necessarily mean the provider can deliver it reliably at your peak volume.
Ask for examples of similar projects and clarify whether work is completed by the provider’s employees or outsourced to another party.
7. Verify Scalability and Peak Planning
Ask for a peak-season plan covering forecast deadlines, labour, storage, receiving cut-offs, carrier collections, and communication.
Discuss what happens if volume doubles, a promotion exceeds the forecast, or inventory must move quickly. Also ask whether storage space and fees can decrease when demand slows.
A provider should explain how much advance notice it needs for promotions, new product launches, and seasonal inventory arrivals. Your team should also understand whether peak-period order cut-offs or service levels differ from normal operations.
Scalability should be supported by capacity planning and documented procedures, not treated as a general promise.
8. Assess Support and Onboarding
Meet the people who would manage your account. Clarify who owns operational, technical, billing, and urgent issues.
Evaluate:
- Normal response times
- Operating hours
- Escalation contacts
- Reporting frequency
- Corrective-action procedures
- Implementation responsibilities
- Inventory transfer
- System testing
- Cutover timing
Request references from brands with comparable products or channels. Where practical, visit the facility or conduct a detailed virtual operational review.
A clear onboarding plan should identify deadlines, responsible parties, data requirements, test orders, stock-reconciliation procedures, and contingency steps. This reduces the risk of delayed orders or inaccurate inventory during the transition.
9. Use a Weighted Evaluation Scorecard
Use the following sample weighting as a starting point, then adjust it to reflect your products, channels, and operational risks:
- Operational and product fit: 20%
- Service levels and quality: 15%
- Technology and visibility: 15%
- Pricing transparency: 15%
- Warehouse network and shipping: 15%
- Scalability: 10%
- Returns and added services: 5%
- Support and onboarding: 5%
Require evidence for high scores, such as system demonstrations, sample reports, written procedures, contract language, and client references.
Record critical risks separately because one serious integration, capacity, or compliance gap may outweigh a strong overall score. For example, an inexpensive provider should not receive a high final rating if it cannot connect with an essential marketplace or manage your peak volume.
Evaluate Lansil Global as a Supply Chain Partner

Our Shenzhen team works with a network of more than 2,000 factories, supports supplier negotiations and product sampling, and assists with private-label, white-label, and ODM manufacturing.
Before products leave China, our in-house quality control team can conduct testing and provide detailed quality control reports. Inventory can then move by air or sea into our warehousing and fulfillment network. We offer direct China fulfillment from Shenzhen, U.S. order fulfillment from Pennsylvania and Nevada, and Amazon FBA preparation.
This connected process may help ecommerce brands reduce handoffs across sourcing, production, inspection, global shipping, inventory storage, and 3PL order fulfillment. Contact Lansil Global with your product requirements, order profile, destinations, and growth plan to discuss a suitable operating structure for growth.
Choosing a 3PL is a long-term operational decision. Evaluate each provider’s capabilities, systems, costs, service commitments, and support structure against your own business data.
A structured checklist and weighted scorecard make comparisons clearer and reduce the risk of discovering important limitations after onboarding. The most suitable provider should be able to support your current requirements while adapting to new products, channels, markets, and order volumes.
