Returns with 3PL and DHL
When you outsource fulfillment to a 3PL service provider, you delegate more than outbound shipping – returns also become a shared process between shop, warehouse partner and carrier. DHL is the most common returns carrier in Germany: nationwide parcel shops, Packstations and digital label creation make returns easy for customers. For retailers, this creates an interface of contract, technology and quality standards that must be clearly defined.
This guide explains how returns work with 3PL and DHL: from label creation through goods receipt at the partner to KPIs, costs and typical sources of error. Target audience: online shops with external fulfillment, procurement teams and operations teams looking to professionalize their returns processes.
Why 3PL and DHL work well together for returns
A Third-Party Logistics provider (3PL) handles warehousing, picking and shipping. Returns are typically part of the scope of services of 3PL providers – either as a standard module or as an add-on service. DHL provides transport back to the partner's warehouse. This combination is particularly common in industries with high return rates (fashion, shoes, electronics).
The key advantages of this setup:
- Scalability: Return peaks during peak seasons are handled by the partner, not in your own basement warehouse
- Customer proximity: DHL drop-off points are densely available nationwide – short distances for end customers
- Tracking: Returns can be tracked like outbound parcels and integrated into shop or WMS systems
- Specialization: 3PL teams are trained in returns goods receipt, inspection and restocking
- Cost planning: Return fees can be structured in the 3PL contract and DHL tariff
Division of roles: Who does what?
With outsourced fulfillment and DHL as the returns carrier, there are three main actors. Unclear responsibilities are one of the most common causes of delayed refunds and inventory discrepancies.

Not every setup is the same. The choice of model affects costs, customer experience and IT effort.
Comparison of common setups
Details on DHL products can be found in the article DHL Returns and Send-Backs. For technical label creation, see Returns Portal and Labels.
IT integration and data flow
Returns with 3PL only work reliably when systems run in sync. Typical interfaces:
- Shop / OMS: Customer registers return, RMA number is generated
- Shipping software or DHL API: Return label with recipient address of 3PL warehouse
- WMS at 3PL: Expects incoming return based on RMA, order or shipment number
- Status feedback: After inspection, 3PL reports "A-stock", "B-stock" or "Rejected" to shop
- ERP / Payment: Refund or credit note is triggered
Recommended minimum data per return:
- Order number and RMA number
- SKU, quantity and return reason
- DHL shipment number (return)
- Disposition rules (restocking, store B-stock, disposal)
SLA and contract with the 3PL partner
Returns must be defined in the contract and SLA just as precisely as outbound shipping. Negotiate at least these points:

Understanding the cost structure
Return costs consist of several items. Transparent billing prevents surprises on the monthly invoice.
Typical cost blocks:
- DHL return postage: Depends on size, weight and tariff contract
- 3PL returns goods receipt: Acceptance, scan, assignment (often per parcel or per line item)
- Quality inspection: Visual check, functional test, refurbishment
- Restocking: Put-away, labeling, repackaging if needed
- B-stock / disposal: Separate rates for non-saleable goods
- IT / Label: API fees, portal licenses, support
Tips for cost optimization can be found under Reduce return costs. The combination of digital label on demand (no fixed costs for unused inserts) and clear disposition rules at the partner often pays off.
Practical example: Fashion shop with 3PL in NRW
An online fashion retailer with 800 orders per day stores goods at a 3PL in North Rhine-Westphalia. Return rate: 42 percent. Setup:
- Customer registers return in shop portal and selects return reason
- Shop generates DHL return label via API, recipient is 3PL warehouse with RMA in reference field
- Customer drops off parcel at parcel shop; tracking event "Return received" triggers customer email
- 3PL scans parcel within 24 hours, inspects items (label, hygiene, damage)
- A-stock goes into saleable inventory, B-stock into separate warehouse – see B-Stock and Second Life
- Shop receives webhook "Return completed" and refunds automatically
Result after six months: Average time from delivery to refund dropped from 7 to 3 business days, support tickets for returns down 28 percent.
Common mistakes and how to avoid them
Typical pitfalls with 3PL-DHL returns:
- Wrong recipient address on label: Return goes to retailer instead of 3PL – manual rebooking required
- Missing RMA on parcel: Goods cannot be assigned
- Different SKU logic: Shop SKU ≠ warehouse SKU, booking fails
- No peak plan: Returns area backs up after Christmas season
- Manual refund: Shop waits for email instead of automatic status
Frequently asked questions about returns with 3PL and DHL:
Who pays DHL return postage?
Defined contractually: retailer, customer or shared.
Can the customer return to any 3PL warehouse?
No, only to the address specified on the label.
How quickly must the 3PL inspect?
According to SLA, typically 24–48 h after delivery.
What happens with rejected returns?
Return shipment to customer or disposal according to rules.
Do I need a separate returns warehouse?
Often no; 3PL separates zones within the existing FC.
Checklist: Setting up returns with 3PL and DHL
Before go-live or when switching providers, check off these points:
- Returns documented in 3PL contract and SLA with KPIs and prices
- DHL return product selected (portal, API, insert) and tested
- Recipient address of all 3PL locations stored for labels
- RMA workflow between shop, middleware and WMS tested
- Disposition rules for A-stock, B-stock and quarantine fixed in writing
- Tracking events DHL → shop connected for customer communication
- Peak capacity for returns (November–January) contractually secured
- Reporting: return rate, turnaround time, B-stock share evaluable monthly
- Fallback defined for API outage (manual label, support process)
- Legal obligations for withdrawal and refund aligned with process
Conclusion
Returns with 3PL and DHL are not a side product of fulfillment, but a separate process strand involving carrier, warehouse partner and shop system. Those who clearly define roles, SLA, IT integration and costs from the start benefit from faster refunds, more accurate inventory and happier customers.
