Understanding pick and pack pricing structures
Pick and pack warehouse costs vary significantly based on order volume, product characteristics and service level requirements. Most providers use a combination of storage fees, pick fees, pack fees and shipping costs to calculate total fulfillment expenses.
Average 3PL pick & pack/ storage fees by monthly order volume |
|||
| Monthly order volume | Pick & pack fee (per order) |
Storage fee | |
| Per cu-ft | Per bin | ||
| > 1,000 | $2.00 – $3.75 | $0.45 – $0.75 | ~$4 |
| 1,000 – 5,000 | $1.80 – $3.00 | $0.45 – $0.55 | ~$3.50 |
| 5,000 – 10,000 | $1.50 – $2.50 | $0.45 – $0.55 | ~$3.00 |
| 10,000+ | $1.50 – $2.00 | $0.45 – $0.50 | ~$2.50 |
In addition to these more standard fees, pick and pack warehouses often include hidden fees that may negatively impact your contract. The most common examples include:
Common hidden fees in 3PLs |
|
| Hidden fee | Average fee amount |
| Setup and onboarding fees | $500-$2,500 |
| Account management fees | $200-$500 monthly |
| Returns processing | $2-$5 per return |
| Special handling for fragile items | $1-$3 per order |
| Peak season surcharges | 15-25% during Q4 |
Creating a more efficient workflow for your picking and packing typically comes in one of two forms:
Choosing the right 3PL requires evaluating capabilities that directly impact your customer experience and operational efficiency. Focus on technology integration, geographic coverage and service flexibility rather than just price.

Step-by-step transition to pick and pack warehouse services
Successfully transitioning to outsourced fulfillment requires careful planning and execution. Once you’ve narrowed down your options from 3-5 choices to your final selection, the average onboarding process takes 30-60 days, but proper preparation can reduce this timeline significantly.
Pick and pack implementation process |
||||
| Implementation phase | Key activities | Success metrics | ||
| Week 1-2 | Provider selection, contract negotiation | After 3+ proposals received, final choice selected | ||
| Week 3-4 | System integration, API testing | 100% order sync accuracy | ||
| Week 5-6 | Inventory transfer, staff training | Zero inventory discrepancies | ||
| Week 7-8 | Soft launch, performance monitoring | 99%+ order accuracy | ||
Note: Each and every client is different and custom timelines are provided during the original selection process. These time ranges are estimates and could vary depending on the complexity of the operation and the specific needs of each company.
Finalize your selection from your top 3-5 potential providers using the criteria outlined above. Request detailed proposals including pricing, SLAs and implementation timelines. Cart.com's 30-day average onboarding time reflects streamlined processes that minimize business disruption.
Negotiate contract terms that protect your interests, including performance guarantees, termination clauses and pricing escalation limits. Avoid providers requiring long-term commitments without proven performance.
Work with your chosen provider to integrate systems and establish data flows. This includes connecting your ecommerce platform, configuring inventory sync and setting up order routing rules. Test the integration thoroughly with sample orders before going live.
Coordinate the physical transfer of inventory to the fulfillment center. Most providers offer inventory receiving services, but accurate counts and condition verification are critical. Plan for a soft launch with limited SKUs or order types before full implementation.
Once these stages are complete, the pick and pack warehouse should be ready to take over your fulfillment. As you proceed, keep an eye out for common implementation challenges:
