FAQ · 01
Fulfilment & 3PL basics
Start with the operating model: what a 3PL actually owns, what ecommerce fulfilment includes and what is worth comparing before you hand over stock.
What exactly does FLEX. do as a 3PL?
FLEX. runs third-party logistics for ecommerce businesses selling in Europe. We receive inventory, put it into controlled warehouse locations, process orders from connected sales channels, pick and pack parcels, hand shipments to carriers and process the stock that comes back through returns. The same warehouse operation can also support B2B movements and Amazon-related flows such as FBA prep, pre-Amazon storage, forwarding and removal orders. The exact mix is set around your operation rather than a fixed bundle. See the wider ecommerce fulfilment model.
What does ecommerce fulfilment in Europe involve?
Ecommerce fulfilment covers the warehouse work between receiving stock and closing the order cycle. That normally includes receiving and putaway, inventory control, order intake, picking, packing, carrier handover, tracking updates and returns. For a European setup, stock position matters too: the warehouse location affects parcel distance, replenishment and cross-border complexity. FLEX. brings those steps into one operating flow while your tax, customs and product-compliance obligations remain with the appropriate business advisers and responsible parties. Explore ecommerce fulfilment in Europe.
What should I compare when choosing a fulfilment company in Europe?
Compare the parts that change customer experience and operating cost after go-live: warehouse location, receiving rules, inventory accuracy, dispatch cut-offs, carrier options, returns handling, integration ownership, peak planning and the charges that sit outside the headline pick fee. Ask how exceptions are handled, who owns a stock discrepancy and what the provider will refuse or escalate. A strong rate card with a weak operating process is still a weak fit. Use the ecommerce fulfilment overview as the baseline for your comparison.
FAQ · 02
Getting started, pricing & switching
Good onboarding starts with the operating facts. These are the questions that shape the quote, the migration plan and the first weeks after go-live.
What information does FLEX. need to prepare a quote?
For a useful first quote, send the SKU count and product categories, dimensions and weight range, average monthly orders and peak volume, average lines or units per order, sales channels, destination markets and the expected inbound profile. Add anything that changes warehouse work: branded packaging, kitting, returns, batch or expiry tracking, B2B case orders, restricted goods or other special handling. The more clearly the workload is described, the less the quote depends on assumptions. Send the profile through Contact FLEX..
How do I switch fulfilment provider without disrupting orders?
Treat the move as an operating migration rather than a warehouse booking. First freeze the SKU master, packing rules, integrations and returns policy. Then test order and stock flows before the main inventory transfer. Decide whether you need a short period of parallel running or a single cut-over, and reconcile stock before the old operation is closed. Peak season is usually the worst time to discover unresolved master-data problems. The order fulfilment page shows the operating pieces that need to move together.
What drives fulfilment, storage and programme costs?
The cost is shaped by the work and space your operation consumes. Typical drivers include receiving, storage profile, order lines and units, pick and pack steps, packaging materials, parcel weight and dimensions, destination, returns, rework, kitting and any programme-specific handling. A migration can also include stock transfer, dual-running time and integration work. Compare the full operating model rather than one headline fee. FLEX. prices against the actual profile, so current commercial terms belong in a quote rather than a generic FAQ. Start with ecommerce fulfilment.
Is there a minimum order volume to work with FLEX.?
Fit is assessed from the whole operation rather than monthly orders alone. SKU count, storage footprint, order frequency, handling complexity, destination mix, integrations and expected growth can make two businesses with the same order volume very different warehouse accounts. If your volumes are still developing, send the current average and a realistic peak or growth range; FLEX. can then confirm whether the operation is a practical match and which service structure fits. For the current commercial threshold and plan, use Contact FLEX..
How long does onboarding take?
There is no useful universal onboarding time. A clean catalogue with a standard integration and simple packing rules can move much faster than a multi-channel operation with custom routing, batch data, complex returns or a large stock transfer. The critical steps are data mapping, integration testing, warehouse rules, inbound preparation, test orders and stock reconciliation. FLEX. agrees the sequence against your real setup before the move begins, so the timeline can be planned around stock arrival and trading dates. Send the profile through Contact FLEX..

FAQ · 03
European network & cross-border
Warehouse geography is an operating decision. The right stock position depends on customers, channels, replenishment and the rules around the goods.
Can a non-EU brand hold inventory and fulfil orders from Europe?
Yes, a non-EU business can use an EU warehouse as part of its European operating model, but the warehouse contract is only one part of the setup. Holding inventory in the EU can create VAT, customs, importer and product-compliance obligations that depend on the goods, entity structure and sales routes. FLEX. can run the agreed receiving, storage and fulfilment workflow; the seller or importer should establish the correct legal and tax position before stock moves. The EU market-entry guide is the right next read.
Which countries and markets can FLEX. ship to?
FLEX. is set up for European ecommerce fulfilment, with carrier routing chosen around the warehouse, destination, parcel profile and service required. The exact country and service combination should be confirmed for your products rather than assumed from a generic map, especially for restricted goods, oversized items or time-critical programmes. Send the target markets with your quote profile and FLEX. can map the appropriate warehouse and carrier routes. See the broader ecommerce fulfilment model for how the network fits together.
Do I need a warehouse in every country I sell to?
Usually no. One well-positioned stock pool can serve several markets cross-border, and adding a warehouse only makes sense when the delivery promise, volume, marketplace rule, returns route, replenishment pattern or tax structure justifies it. Splitting inventory too early can create extra transfers and more stock to reconcile. The useful question is where each SKU should sit for the service level you need. The EU market-entry guide explains the wider operating choices.
Where are FLEX. warehouses located?
FLEX. currently operates six warehouse locations across Germany, France, Poland and the United Kingdom: three German sites at Hermsdorf/Magdeburg Logistics Park, Wilhelmshaven/JadeWeserPort and OSN3 in Lotte, the CAM1 site at Épinoy-Cambrai in France, KUT1 at Kutno Logistics Park in Poland, and SWA2 at Kings Dock in Swansea. The best location for an account depends on its inbound route, destination markets, stock profile and service mix. See the network and company context on Meet FLEX..
FAQ · 04
Orders, inventory & omnichannel
Most ecommerce complexity sits between the sales channel and the shelf. These answers cover stock ownership, channel routing, dispatch and the data written back after an order moves.
Can one stock pool serve my webshop, marketplaces and B2B channels?
Yes, when the channel integrations, stock-allocation rules and order priorities are defined around one warehouse inventory model. The same physical stock can serve a webshop, marketplaces and agreed B2B flows while the WMS records what is available, reserved, picked or returned. Some channels may need safety buffers or separate availability rules, so ‘one pool’ does not mean every channel sees the same sellable quantity at every moment. See how omnichannel fulfilment is structured.
Can FLEX. handle B2B, wholesale and D2C orders from the same inventory?
Yes, provided each order type has a clear fulfilment rule. D2C may need parcel packing and customer inserts, while wholesale can require case quantities, pallet labels, delivery references or appointment information. Those differences are mapped without forcing you to maintain separate stock pools for the same SKU unless there is a commercial or channel reason to do so. Inventory stays under one warehouse view while order type determines the execution path. The B2B and B2C fulfilment guide goes deeper into the split.
How does FLEX. handle seasonal peaks, launches and promotional spikes?
Peak handling starts before the orders arrive. FLEX. uses the forecast to plan receiving, pick locations, labour, packaging, pre-built kits where useful and carrier hand-offs. The key inputs are the expected volume curve, SKU concentration, campaign dates and any promise that changes at peak. Capacity and cut-offs should be agreed for the specific account rather than assumed from an ordinary week. If a launch depends on a fixed date, surface that early in the planning. Start with ecommerce fulfilment and include the peak profile in the quote request.
How does inventory visibility and stock synchronisation work?
The warehouse record changes as stock is received, put away, reserved, picked, returned or adjusted. Connected sales channels can then receive the inventory updates supported by the relevant integration and the rules agreed for that channel. Safety buffers, reserved stock or channel-specific allocations can be used where overselling risk or marketplace logic requires them. The exact sync behaviour depends on the platform and connector, so it is mapped during integration setup rather than treated as one universal feed. See the integration guides.
What is omnichannel fulfilment?
Omnichannel fulfilment is one warehouse operation serving orders from several sales channels. A brand might use the same stock for its own ecommerce store, marketplaces, selected Amazon flows, B2B orders or campaign channels while the WMS keeps the physical inventory under one operational view. Each channel can still have its own allocation, packing, carrier and tracking rules. The benefit is operational consistency and less duplicated stock, provided the integrations and priorities are designed properly. See omnichannel fulfilment.
Are tracking updates written back to my sales channels?
They can be, where the connected platform and integration support the required shipment events. A typical flow sends the shipment confirmation and tracking reference back after dispatch, which keeps the customer-facing order status aligned with the warehouse event. Exact fields, timing and multi-parcel behaviour vary by channel, so the integration is tested before live volume. Custom platforms may need a different mapping from a standard connector. The integration guides show the platform-specific layer.
How does FLEX. prevent wrong-item picks?
Accuracy is built around identification and scan points. The SKU or barcode, warehouse location and order line need to agree before the item moves through the pick-and-pack flow. Variant-heavy ranges can add attributes such as size, colour, serial or batch where the operating model requires them. Exceptions are held for review instead of being guessed at the bench. No warehouse should promise that an error can never occur; the goal is to design the process so mismatches are detected before dispatch. See pick & pack services.
How fast can FLEX. dispatch orders?
Same-day dispatch is available for agreed FLEX. flows when orders arrive inside the account cut-off and the stock is ready to pick. The actual promise depends on warehouse, service, channel, order profile, operating day and carrier collection, so the cut-off belongs in the account SLA rather than a universal site-wide guarantee. Peak periods and special handling can also change the practical window. If dispatch speed is commercially critical, include the required promise in the onboarding brief. See ecommerce fulfilment.
FROM ANSWER TO OPERATING RULE
A useful FAQ should survive the warehouse floor.
Every answer on this page eventually becomes something practical: an inbound field, a stock rule, a scan, a packing instruction, a carrier decision or a returns disposition. That is why the edge cases matter. Send the awkward SKU, the unusual channel rule or the return you are unsure how to grade; the operating plan is built around those details before stock starts moving.
AT INBOUND
Define what must be identified, checked and recorded before stock becomes available.
AT DISPATCH
Define the pick, packing, carrier and timing rules the team can follow consistently.
ON RETURN
Define the evidence and condition rules that decide restock, rework, quarantine or disposal.
FAQ · 05
Warehousing, packing & value-added services
This is where the warehouse work gets specific: packing rules, storage profile, kits, labels and the physical characteristics that change how an order can move.
How does FLEX. choose packing for different products?
Packing is defined from the product and the order, not from one standard box rule. Dimensions, weight, fragility, leakage risk, presentation, carrier limits, destination and channel requirements can all change the pack. The agreed operating spec can also include branded materials, inserts, seals, dunnage or product-specific handling. Where a product has regulatory or dangerous-goods packaging requirements, those need to be confirmed before the SKU is accepted. See the practical scope of pick & pack services.
What is kitting and assembly?
Kitting combines several components or SKUs into a defined set before it ships. The set might be a promotional bundle, launch kit, subscription box, sample pack or product-and-accessory combination. A good kitting instruction includes the bill of materials, quantities, presentation order, labels, inserts and any variant logic. Kits can be built in batches before demand arrives or assembled against orders, depending on volume and shelf-life considerations. See kitting and assembly.
Can FLEX. handle bulky, oversized or heavy items?
Potentially, but those lines need to be reviewed before onboarding. Dimensions and weight affect storage location, handling equipment, packaging, carrier eligibility, surcharges and sometimes the warehouse that can take the SKU. Send the largest and heaviest units in the range rather than only an average carton profile. FLEX. can then confirm the practical site and outbound route for the accepted items. The warehouse services page is the right starting point for this type of profile.
Can storage scale up or down with demand?
Yes, within the capacity and operating profile agreed for the account. Active pick stock, reserve inventory, seasonal stock and long-term buffer stock do not need to use the same storage pattern. The useful plan separates what must stay close to the pick face from what can sit in reserve until replenishment is needed. Large seasonal changes should be forecast so space and handling can be planned before the stock arrives. See long-term and buffer storage.
Can FLEX. use discreet or anonymous packaging?
Yes, where discreet packing is part of the agreed product workflow. A plain outer can avoid unnecessary product or brand information while still carrying the labels and declarations required by the carrier, customs route or product class. Inserts, return information and internal identifiers can be handled separately from the external presentation. If the product itself has mandatory warnings or transport markings, those requirements still apply. Discuss the exact presentation rules under pick & pack services.
Can FLEX. personalise kits by recipient, market or campaign?
Yes, when the data that controls the variant is available before assembly or dispatch. A kit can change by campaign, language, market, customer segment or other agreed rule, with the bill of materials and inserts tied to that variant. Personalisation increases the number of possible combinations, so the data source, error checks, build timing and exception route need to be clear. For recurring or high-volume campaigns, pre-building selected variants can also make sense. See kitting and assembly.
Can FLEX. use my branded packaging and boxes?
Yes. Branded boxes, mailers, tape, inserts and other customer-facing materials can be included in the packing specification. You can provide packaging stock for the warehouse to hold, or sourcing can be discussed as part of the operating setup. The important part is version control: the team needs to know which material applies to which SKU, market or campaign, and what happens when branded stock runs out. See pick & pack services.
What is dimensional weight and how can it affect shipping cost?
Dimensional weight is a carrier method for pricing the space a parcel occupies as well as its physical weight. A light product in a large box can therefore be billed at a higher weight than the scale shows. The divisor and rules vary by carrier and service, so the exact charge needs to be read from the selected tariff. Right-sized packaging can reduce empty space, material use and avoidable billable weight. See the shipping and carrier glossary for the terminology around parcel pricing.
What labelling information is required for inbound stock?
At minimum, units need a clear identifier that matches the SKU or barcode in the agreed product master. Inbound cartons or pallets should also carry the information needed to reconcile the shipment, such as the account or shipment reference, carton count and the SKU quantities inside. Some workflows need more: batch, lot, expiry, serial, country or channel-specific data. The exact receiving standard is set before the first inbound so the warehouse can check stock without interpreting supplier paperwork on the fly. See warehouse services.
FAQ · 06
Returns & reverse logistics
Returns become manageable when the disposition rule exists before the parcel comes back. These are the two central questions; product-specific exceptions stay on the relevant service or industry page.
How does FLEX. receive, grade and process customer returns?
Returned stock is identified against the order or return reference, inspected to the checks agreed for that product, and then routed by condition. Typical outcomes include restock, repack or light rework, quarantine, return to the merchant or disposal. The grading policy belongs in the operating plan before go-live so the warehouse team is applying your rule rather than making commercial decisions item by item. Photos or additional evidence can be added where the workflow requires them. See returns processing.
Can returned or open-box stock be refurbished and returned to sellable inventory?
Sometimes. If the product class and your grading policy allow resale, FLEX. can route suitable units through agreed rework such as repacking, relabelling, replacing inserts or other light preparation before they return to sellable stock. Testing, repair, authentication or certification should never be assumed; those activities need a separately confirmed process or specialist owner. The key is to define the condition thresholds and evidence before returns start arriving. See returns processing.

FAQ · 07
Amazon FBA, FBM & Seller Fulfilled Prime
Amazon adds its own inbound, inventory and Prime rules to the warehouse flow. Keep the operating model current and check programme requirements close to go-live.
What does Amazon FBA prep include?
FBA prep is the work required to make seller inventory ready for the current Amazon inbound requirements before it reaches a fulfilment centre. Depending on the SKU and shipment, that can include inspection, product or FNSKU labelling, bagging or protective preparation, bundling, re-boxing, carton checks, pallet preparation and shipment labels. Requirements vary by product and can change, so the shipment plan and current Amazon guidance remain the authority for what is required. FLEX. applies the agreed prep rules through Amazon FBA prep.
Can FLEX. hold stock outside Amazon and forward it gradually into FBA?
Yes. Pre-Amazon buffer storage lets you keep reserve inventory in a FLEX. warehouse and release replenishment into FBA as it is needed instead of sending the entire stock position into Amazon at once. That can help when you are managing storage limits, launch timing, aged inventory risk or uncertain demand. Stock can move from storage into prep, carton or pallet checks and then forwarding to the FC identified in the shipment plan. See Amazon forwarding for the replenishment flow.
What happens if an Amazon inbound shipment is refused or received slowly?
First establish where the stock physically is and what Amazon or the carrier has recorded against the shipment. A refused load may need a return route, a new appointment, rework or a corrected inbound plan; a slow receipt may require reconciliation rather than another shipment. FLEX. can hold, inspect, rework and re-forward inventory once the next route is clear, but Amazon controls the FC receiving decision. For the warehouse side of the recovery, see Amazon forwarding and use the FC Directory to confirm the destination code and location.
How does FLEX. handle Amazon removal orders?
The seller creates the removal order in Seller Central and chooses the permitted removal method or return destination. When inventory is routed back to FLEX., the warehouse can receive and identify it, inspect condition, grade it to the agreed policy and then route it into restock, rework, relabelling, storage, resale fulfilment or disposal as appropriate. The practical workflow depends on whether Amazon returns the units as fulfilable or unfulfillable stock and what evidence you need. See Amazon removals for the FLEX. side of the process.
What is Seller Fulfilled Prime?
Seller Fulfilled Prime is an Amazon programme that lets eligible sellers fulfil Prime orders outside FBA from the warehouse setup registered for the programme while keeping the Prime customer promise. The seller still has to meet the programme rules for that marketplace, complete the trial or eligibility process and maintain the required delivery performance. Those requirements are not identical across every Amazon country, so the current marketplace policy must be checked before setup. FLEX. supports the warehouse execution for agreed Seller Fulfilled Prime flows.
What does Seller Fulfilled Prime require from a fulfilment provider?
The provider has to run the order flow tightly enough for the seller to meet the current Prime programme requirements in that marketplace. That means reliable order intake, the correct warehouse location, rapid pick and pack, valid tracking, eligible shipping methods, controlled cancellations and a returns flow that matches Amazon policy. Amazon also uses a trial or qualification stage and ongoing performance measures, and the thresholds can differ by marketplace or change over time. FLEX. scopes SFP against the seller account and current rules rather than publishing one universal metric. See Seller Fulfilled Prime.
What does an Amazon FC code mean?
An Amazon FC code is the short identifier used for a particular fulfilment-centre destination in Amazon's logistics network. Sellers encounter the code in shipment routing and inbound instructions, and it needs to be matched to the current address and shipment plan rather than treated as a permanent standalone address book entry. Codes are useful operational shorthand, especially when several Amazon facilities serve the same country or region. Use the Amazon FC Directory to look up codes and warehouse locations, then confirm the destination in Seller Central before dispatch.
Are Amazon fulfilment centres the same as sort centres or delivery stations?
No. A fulfilment centre stores inventory and is where Amazon associates and systems pick, pack and ship customer orders. A sort centre sorts and consolidates parcels by destination. A delivery station sits closer to the last mile and prepares parcels for final delivery routes. For seller inventory entering FBA, the fulfilment centre is the relevant warehouse destination; a sort centre or delivery station should not be substituted because the name sounds local. See the Amazon FC Directory for FC codes and locations.
FAQ · 08
Integrations & marketplaces
Integration should follow the operating model. Start with the stock and order behaviour you need, then choose the cleanest technical route for the platform.
How long does ecommerce integration setup take?
The connector itself is only one part of setup. The real timeline is driven by product and location mapping, stock rules, order routing, returns behaviour, tracking write-back, any platform customisation and the test cycle. A standard store with clean data is usually simpler than a heavily customised build or a multi-location setup. FLEX. tests the intended live workflow before normal volume starts, because a technically connected store can still have the wrong operating rules. See the platform-specific integration guides.
Should I use a connector or module, or a direct API?
Use the simplest route that supports the operating behaviour you actually need. A standard connector or platform module is usually easier to implement and support when its order, inventory and tracking model already fits the business. A direct API can make sense for customised platforms, unusual routing, middleware or teams that want tighter technical ownership. Availability differs by platform, so this is a mapping decision rather than a universal preference. Start with the integration guides and bring your developer or agency into the technical discussion where needed.
FAQ · 09
Product handling, traceability & compliance
Special handling begins by defining what the warehouse must capture, check or stop. Legal product compliance stays with the responsible seller, importer, manufacturer or qualified specialist.
Can FLEX. track batch, lot, expiry and best-before dates?
Yes, where those fields are part of the agreed product and warehouse data model. Batch, lot, expiry or best-before information can be captured at receiving and carried into stock rotation, picking and outbound history. The operating rule may use FIFO or FEFO depending on the product and requirement, with short-dated or held stock treated according to the account policy. The exact identifiers and scan points should be agreed before the first inbound. See warehouse services for the underlying inventory workflow.
Can FLEX. handle batteries, aerosols or other restricted goods?
Only after the product has been correctly classified and the proposed warehouse, storage method and carrier route have been checked for that classification. Batteries, aerosols, paints, solvents and similar lines can fall under dangerous-goods or carrier restrictions, and acceptance is not automatic. The merchant or manufacturer needs to provide the correct product information and documentation; FLEX. then confirms whether the SKU can be handled in the proposed flow and which services are eligible. Start with the Compliance Guides before sending restricted stock.
Can FLEX. support product recalls and withdrawals?
FLEX. can support the warehouse side of a recall or withdrawal when the required batch, lot, serial or other traceability data is part of the agreed workflow. That can include identifying affected stock on hand, quarantining it, stopping further dispatch and retrieving outbound history for the relevant identifier. The decision to initiate a recall, regulatory notification and legal product responsibility remain with the product owner and other responsible parties. The traceability model needs to exist before an incident occurs. See the Compliance Guides and relevant industry requirements.
How does FLEX. handle products with CE marking, age-grading or safety-warning requirements?
Where an agreed warehouse checklist calls for it, FLEX. can check for the presence of specified markings, labels or warnings during receiving or another defined control point. That is an operational check against the information you supply. It does not replace conformity assessment, technical documentation, authorised-person responsibilities or any legal obligation that sits with the manufacturer, importer, distributor or seller. If a missing mark should place stock on hold, that rule is written into the workflow before go-live. See the Compliance Guides for the broader context.
Can FLEX. capture serial numbers, IMEIs or certificates?
Yes, where the identifier is part of the agreed data model and the workflow supports the required capture point. Depending on the product, a serial number, IMEI or certificate reference may be recorded at inbound, pick, pack, dispatch or return and tied to the relevant unit or order. The purpose and retrieval requirement should be defined before stock arrives. Recording an identifier is a traceability function; it is not authentication, appraisal or certification unless a separate specialist process has been explicitly agreed. See warehouse services.
