List the work that must happen from inbound to dispatch: receiving controls, storage profile, pick and pack, packaging, value-added preparation, returns and transport hand-off. Two quotes are not comparable when one excludes tasks the other includes.
Recent orders and active SKU count
Units, weight and packed dimensions per order
Destination, return and seasonality mix

2. Verify the physical operation and accountability
Confirm the legal company, operating address and the team responsible for stock and exceptions. A provider that markets Portugal but silently passes the work to an unnamed third party creates an extra hand-off and a weaker chain of responsibility.

3. Model the complete cost per order
Separate inbound, storage, pick and pack, packaging, special handling, transport, returns, minimums and surcharges. Build at least one normal-month scenario and one peak-month scenario instead of comparing a single headline fee.

4. Test the data and exception flow
Order import, SKU identifiers, stock reconciliation, tracking return and status updates should be tested with representative records. Define who owns mismatches, damaged arrivals, address errors, carrier holds and customer returns before launch.
05
5. Agree service levels that can be evidenced
Cut-off times, receiving targets and dispatch expectations only become useful when the starting event, exclusions and evidence are clear. Ask what record will show that an order was received, prepared, held or handed to the carrier.

6. Start with a controlled pilot
Use a limited set of SKUs and representative orders to validate data, packaging, carrier labels, tracking and exceptions. Reconcile the pilot before moving the remaining stock or increasing volume.
Third-party logistics describes operational logistics performed for another company, typically including some combination of receiving, storage, order preparation, returns and transport coordination.
How can I tell whether a 3PL operates directly in Portugal?
Verify the legal entity, full operating address, receiving instructions, responsible team and the evidence produced during inbound, preparation and dispatch.
What data is needed for a useful 3PL proposal?
Provide recent orders, SKU and stock profile, units per order, packed dimensions, destinations, returns, peak pattern, special handling and the expected start date.
Can a 3PL in Portugal also prepare Amazon FBA stock?
It can when FBA preparation is a defined workflow. FNSKU, bagging, bundling, carton checks and dispatch should follow the seller's current shipment plan and agreed responsibilities.
Should a 3PL migration begin with a pilot?
Yes. A controlled pilot exposes data, packaging and exception issues before the full inventory and order flow depend on the new operation.
