Selling on Trendyol, Hepsiburada and Amazon.com.tr: A Marketplace Fulfillment Guide

Marketplace fulfillment in Türkiye means that orders from Trendyol, Hepsiburada, Amazon.com.tr, n11 and Pazarama flow into one warehouse system, are picked with barcode verification, labelled with the carrier label the marketplace generated, and handed to the carrier inside the marketplace’s dispatch window. Done well, the brand manages one stock and one operation while selling on five storefronts. Done badly, every campaign ends in oversold listings, late-dispatch penalties and a seller score that costs visibility. This guide follows an order from the marketplace to the carrier and explains what has to be in place at each step.

How do Turkish marketplaces work for a brand?

Marketplaces dominate Turkish e-commerce, and most consumers start their search on one of them rather than on a brand’s own site. For a seller, each marketplace provides a storefront, payment collection, customer messaging and, in most cases, carrier contracts and shipping labels. In return it expects the seller to confirm and dispatch orders within a deadline it sets, to pack according to its rules, and to accept returns through its flow. Performance is scored, and the score affects where listings appear.

A few points differ from marketplaces elsewhere. Cash on delivery is offered as a payment method and handled by the carrier. Campaign periods, above all the November campaigns, concentrate a large share of annual volume into a few weeks. And a seller selling from abroad is at a disadvantage: Turkish marketplaces are built around domestic dispatch and domestic returns, which is why brands entering the market set up local fulfillment first.

How does an order travel from the marketplace to the carrier?

Every marketplace order passes through the same nine steps. Where they happen, in the marketplace panel, in the warehouse system or at the packing station, is what a fulfillment set-up decides.

1. Order capture: the warehouse system pulls new orders from each marketplace through its API at short intervals, so an order placed at 10:05 is in the picking queue minutes later, not after someone exports a file.
2. Stock allocation: the system reserves the units against the single stock record. If a unit is not physically available, the order is flagged before a customer is promised something that cannot ship.
3. Picking: the picker is directed to the location; the handheld terminal accepts only the right barcode, and the right lot where lot tracking applies.
4. Packing: contents are verified at the packing station, the parcel is packed to the marketplace’s rules and the brand’s specification.
5. Labelling: the shipping label generated by the marketplace for its contracted carrier is printed and applied; for own-carrier sales the warehouse system creates the label.
6. Documents: the invoice or delivery note your system generated is inserted or sent digitally, depending on the channel.
7. Carrier handover: parcels are sorted by carrier and handed over at the fixed collection time.
8. Status update: the marketplace receives the “shipped” status and tracking number automatically, which stops the dispatch clock.
9. Returns and claims: a return initiated on the marketplace comes back through its carrier, is inspected in the warehouse and reported with its outcome.

The set-up work, from API credentials to test orders, is described on our integrations page.

Who ships: the marketplace’s carrier or your own?

Most Turkish marketplaces contract carriers themselves and generate the label in their panel; some let sellers use their own carrier contract. The choice affects cost, control and what the warehouse has to do.

In practice a brand runs both: marketplace carriers for marketplace orders and its own contract for own-site orders. The warehouse sorts by carrier at the end of the day, which is why one collection time across channels matters.

How do you keep one stock across five marketplaces and your own site?

The most common failure in marketplace operations is not slow picking but split stock: each channel has its own stock bucket, the buckets drift apart, and the brand either oversells during a campaign or holds safety stock five times over. The alternative is one stock record with rules on top of it.

• Single stock, channel reservations: all channels see the same available quantity; a confirmed order reserves units for that channel until it ships.
• Channel buffers: a brand can hold back a share of stock from a given marketplace during a campaign so that its own site or a wholesale order is never starved.
• Stock sync frequency: available quantity is pushed to each marketplace at short intervals; the longer the interval, the larger the oversell window.
• B2B and B2C from one stock: a wholesale order picked by the carton and a marketplace order picked by the unit are deducted from the same record, so nobody has to physically split inventory. Our fulfillment page walks through a real B2B and B2C scenario.

What do marketplace packaging and labelling rules require?

Each marketplace publishes its own rules, and they change, so the warehouse works from the current version rather than from memory. The common themes are: the marketplace label on the outside, placed where the carrier scans it; a parcel that protects the product and matches the declared dimensions; the invoice or delivery note handled as the marketplace specifies; and no third-party promotional material the marketplace does not allow. Brand inserts, gift packaging and sample add-ons are usually possible within those rules. The packaging section of our marketplace logistics page lists what the warehouse checks per channel.

How do marketplace returns and claims work?

The customer initiates the return on the marketplace, the marketplace’s carrier collects it and delivers it to the warehouse. The warehouse inspects the item, records its condition and lot, restocks what is sellable and blocks what is not, then reports the outcome so the marketplace case can be closed. Disputed returns, where the customer claims a wrong or damaged item, are settled with evidence: packing records, weights where available and the inspection record of the return. A warehouse that logs what went into each parcel at the packing station can answer these claims; one that does not pays them. The process is described on our returns and reverse logistics page.

How do you prepare for Legendary November and 11.11?

Turkish marketplaces run their largest campaigns in November, and a few weeks can carry a disproportionate share of the year’s orders. Preparation is operational, not just promotional.

1. Stock in early: campaign stock should be received, counted and put away before the campaign starts, not during it.
2. Pre-packed sets: campaign bundles are kitted in advance and given their own barcode so they pick as one item.
3. Capacity plan: extra picking and packing shifts, packing material stocked for the expected volume, carrier collection times confirmed for the period.
4. Channel buffers: decide before the campaign which channel gets priority if stock runs low.
5. Cut-off and exceptions agreed: campaign peaks and public holidays can change the carrier collection plan; agree the exceptions with the warehouse in advance so the dispatch commitment is realistic.
6. Returns plan: campaign returns arrive in the following weeks and need capacity too.

Which metrics should a marketplace seller watch?

Ask the warehouse to define each metric in writing and to report it monthly. Our KPI assessment helps you check which of these your operation measures today.

Let’s assume: a home-textile brand on two marketplaces and Shopify

Let’s assume a home-textile brand has 120 SKUs, sells on Trendyol and Hepsiburada and runs its own Shopify store, with marketplace orders making up most of its volume. All three channels are connected to the warehouse system and draw from one stock. During the day, orders are pulled from each channel at short intervals and picked with barcode verification. Marketplace orders are labelled with the marketplace carrier’s label, Shopify orders with the brand’s own carrier label, and all parcels are sorted by carrier for the afternoon collection. Available quantity is pushed back to both marketplaces after every allocation, so a sold-out colour disappears from the listing before a second customer can order it. Before November, the brand kits its campaign bundles, moves extra stock in and sets a buffer so Shopify is never starved. Returns from all three channels come back to the same warehouse and are reported with their outcome.
