You.gr Integration: Marketplace API & Centralized Tech Sales Management

About You.gr: Founding, Ownership and Market Position

Founding and Timeline (2010 – Today)

You.gr launched in 2010 in Thessaloniki as the consumer-facing arm of Aktinotek, a long-established Northern Greek IT and consumer-electronics distributor. The platform inherited Aktinotek's supplier network and warehouse infrastructure, which is why You.gr has traditionally led on smartphone, computing and wearables availability in Greece — categories where supply-chain access matters more than marketing spend.

Throughout 2015–2022, You.gr evolved from a 1P electronics e-shop into a hybrid marketplace, opening up to vetted Greek 3P sellers and adding adjacent verticals (audio, smart home, drones, gaming). In parallel, the group launched You Mobile — a telco resale brand for SIMs, mobile plans and device bundles — and the You.gr Plus loyalty programme that rewards repeat customers with free shipping, extended returns and member-only pricing.

You.gr Ownership and Group Structure (2026)

• You.gr S.A. — operating entity, HQ in Thessaloniki
• Aktinotek — IT distribution origin and supplier-side infrastructure provider
• You Mobile — telco/MVNO resale division bundled with device sales
• You.gr Plus — proprietary loyalty programme driving repeat purchase

Position in the Greek E-commerce Landscape

The Greek online retail market is concentrated around three dominant players: Skroutz (price comparison + marketplace, Athens-based), Plaisio (legacy electronics retailer with strong physical presence) and You.gr (Thessaloniki-based tech specialist). You.gr's structural advantage is Northern Greece logistics — faster delivery into Thessaloniki, Macedonia and Thrace — combined with sharper smartphone and wearables pricing thanks to the Aktinotek distribution backbone. For mid-market tech retailers selling Samsung, Xiaomi, Garmin and similar brands, You.gr is the highest-conversion alternative to Skroutz.

You.gr Market Size and Growth (2024–2025)

You.gr has compounded faster than the overall Greek e-commerce market for four consecutive years, driven by the post-pandemic shift to online electronics purchase and by the maturity of the 3P seller programme. The table below summarizes the key operational metrics used by analysts and prospective sellers.

Year	GMV (EUR)	Active Customers	3P Sellers	Key Milestone
2020	~€95M	700K	180	Marketplace opened
2022	~€135M	1.1M	380	You.gr Plus loyalty
2024	~€180M	1.5M+	600+	You Mobile expansion
2025 (forecast)	~€215M	1.8M	780	Marketplace API v2

This trajectory is supported by three structural tailwinds: rising Greek smartphone replacement cycles, the You.gr Plus loyalty flywheel and competitive bundles via You Mobile. For sellers, the operational implication is straightforward — becoming an approved 3P seller on You.gr is one of the fastest organic growth channels currently available in Greek e-commerce.

Opening a You.gr Seller Account (2026 Requirements)

1. Legal and Tax Prerequisites

To sell on You.gr you must operate a tax-registered business in Greece or another EU country with a Greek VAT registration. The marketplace strictly enforces AADE compliance and myDATA e-invoicing for all 3P sellers; sales without compliant electronic invoices are not paid out.

• Greek VAT number (AFM) registered with AADE
• Tax registration certificate (current year)
• Commercial registry extract (GEMI for Greek entities)
• IBAN for marketplace payouts
• myDATA-ready e-invoicing provider (Epsilon Net, SoftOne, Entersoft, Cosmos Business Systems or equivalent)
• Brand authorization documents for protected categories (smartphones, smart home, photography)
• CE / WEEE / REACH compliance declarations where the product category requires

2. Applying via the You.gr Seller Centre

You submit your application at marketplace.you.gr. Standard review takes 7–14 business days. Once approved, You.gr issues your seller ID, API key and API secret, plus access to the Seller Centre where you can manage catalogue, orders, returns and payouts.

3. Product Listing and Content Rules

You.gr enforces a strict content quality bar — particularly for the smartphone, computing and audio categories where buyers compare spec sheets carefully:

• Title: 60–160 characters, brand + model + key spec (e.g. RAM/storage/color)
• Images: White background, minimum 1200×1200px, up to 8 images, no watermarks or overlay text
• Description: HTML supported, minimum 250 characters, English or Greek (Greek strongly preferred for organic ranking)
• Category mapping: You.gr taxonomy ID + attribute set (memory, screen size, connectivity, color)
• GTIN/EAN barcode: Mandatory for branded tech; speeds catalogue matching to existing You.gr master products
• Content score: Must reach 75+; below this threshold the listing is hidden from the buying page

You.gr Commission Rates (2026)

You.gr commissions are competitive versus the wider Greek marketplace landscape, sitting between Skroutz and Plaisio for most tech categories. Rates range from 4% to 17% and exclude 24% VAT, payment-processing fees and category-specific value-added services. The three commission bands below summarize the structure for budgeting purposes:

Net-margin formula: Sale price − Category commission − 24% VAT − Payment fee − Shipping cost − Product cost = Net profit. The Zunapro pricing engine applies this formula per SKU and per category, flagging listings that drift below your minimum margin threshold and optionally activating the repricer to defend your position.

You.gr Marketplace API — Technical Details

The You.gr Marketplace API is a RESTful interface for programmatically syncing products, inventory, orders, pricing and shipments with the You.gr platform. The base URL is https://api.you.gr/marketplace/ and all responses are JSON. Authentication is performed once at the API gateway and persists for the lifetime of the integration.

API Authentication

You.gr uses HTTP Basic Authentication over TLS, with apiKey:apiSecret Base64-encoded in the Authorization header. Tokens do not expire automatically, but You.gr recommends rotating credentials every 6–12 months from the Seller Centre Security tab.

Core Endpoint Groups

• Products API — create/update listings, map You.gr categories, query content-score and master-catalogue matches
• Inventory API — stock and EUR pricing sync (bulk endpoint up to 100 SKUs per request)
• Orders API — list orders, update lifecycle status, generate packing slips
• Shipments API — assign carrier (ACS, Geniki, ELTA, Speedex, BoxNow), print labels, send tracking numbers
• Returns API — fetch return requests, approve/reject, issue credit notes
• Settlements API — payout statements, fees breakdown, reconciliation exports
• Webhooks — real-time callbacks for order creation, status changes and inventory events

Rate Limits and Error Handling

The You.gr API enforces a rate limit of approximately 10 requests per second per seller. Exceeding the limit returns 429 Too Many Requests. Common error codes: 400 (invalid payload — typically missing GTIN or attribute), 401 (authentication failure), 404 (category or master-catalogue product not found), 422 (content-score below threshold), 500 (transient server error — safe to retry). The Zunapro connector wraps all calls with exponential backoff, a dead-letter queue and a webhook reconciler so transient failures never translate into lost orders.

You.gr Feed Integration — Bulk Catalogue Onboarding

For sellers with thousands of SKUs sourced from distributors or their own ERP, manual listing is impractical. The Zunapro feed engine ingests XML, JSON or CSV catalogues from upstream suppliers or your own e-commerce platform and pushes them to You.gr through the Marketplace API — with category mapping, attribute normalization and price rules applied on the fly.

You.gr-Ready Feed Schema

The core fields required on the You.gr side are:

• masterProductId — parent SKU that groups variants
• brand, title, modelCode, sellerSku, gtin
• categoryId (You.gr taxonomy) + attributes (RAM, storage, color, screen size)
• stock, listPrice, salePrice, vatRate (24% / 13% / 6%)
• carrier, warehouseId, handlingTime
• images (1–8 URLs), description (HTML, EL preferred)

From Distributor Feed to You.gr Listing

Most Greek tech distributors — including the Aktinotek-adjacent supply chain — publish stock and price data as XML or CSV. The Zunapro feed module:

1. Polls the supplier feed on an hourly or daily schedule
2. Learns category mappings (manual once, automated afterwards)
3. Normalizes brand, attributes and units to the You.gr taxonomy
4. Applies your margin rules and rounding (EUR-native, VAT-inclusive or exclusive)
5. Tracks out-of-stock states and automatically deactivates listings the supplier can no longer fulfill
6. Pushes everything to You.gr via the API with idempotency guards

Fulfillment on You.gr — 3PL Model and Carrier Mix

Unlike Amazon FBA or fulfilment-heavy regional marketplaces, You.gr operates a 3PL-only model: sellers ship from their own warehouse using a panel of integrated Greek carriers. There is no You.gr-operated fulfillment centre, which keeps storage costs out of your unit economics but means handling time and delivery quality are directly your responsibility.

Integrated Carriers

• ACS Courier — premier nationwide network, fastest for Athens/Thessaloniki next-day
• Geniki Taxydromiki — strong rural and island coverage
• ELTA Courier — Hellenic Post's express service, cost-efficient for lightweight tech accessories
• Speedex — competitive B2C rates, strong for mid-weight electronics
• BoxNow — automated parcel-locker network, lowest delivery cost for tech accessories and wearables

Service-Level Expectations

• Handling time: 1 business day for in-stock SKUs; You.gr penalizes 3-day+ handling
• Mainland delivery: 1–2 business days from Thessaloniki / Athens hubs
• Island delivery: 2–5 business days depending on carrier and destination
• Tracking: tracking numbers must be uploaded via Shipments API before label cut-off

You.gr Seller Score and Cancellation Thresholds

You.gr assigns each seller a 1–10 performance score that directly drives buy-box visibility on the Master Product Page. The metrics that move the score the most are:

• Cancellation rate — stock-out cancellations are punished severely; >2% triggers a warning, >5% risks suspension
• Late shipments — orders not picked up by the carrier within the committed handling time
• Return rate — high for accessories (15–25%), low for smartphones (3–6%); abnormal returns reduce score
• Customer reviews — average rating must stay above 4.0 stars
• Message response time — buyer messages must be answered within 24 hours, 48 max

Zunapro real-time stock synchronization reduces cancellation risk by roughly 90% — the instant a SKU is sold on your storefront, on Skroutz or in your physical store, the You.gr listing is decremented. Combined with the Zunapro order workflow, average handling time typically drops below 8 hours.

You.gr Advertising, Promotions and Smart Pricing

You.gr Advertising Surfaces

• Sponsored Listings — CPC-based placement in category and search results
• Master Product Buy Box boost — paid visibility on shared-catalogue product pages
• You.gr Plus member promotions — loyalty-member-only discounts that drive repeat purchase
• You Mobile bundle slots — co-promotion with telco plans for smartphone SKUs
• Brand stores — banner and display inventory for verified brand-authorized sellers

Smart Pricing (Repricer)

On shared master-product pages, multiple sellers compete for the buy box. The winning factor is a blend of price, seller score and handling time. The Zunapro repricer watches competitor pricing in real time and rebalances your offers within the floor/ceiling bounds you configure — never below your minimum-margin threshold.

myDATA E-Invoicing and AADE Compliance

Every You.gr sale must be invoiced through the AADE myDATA platform — this is a legal requirement, not an optional integration. B2C transactions require a retail receipt (απόδειξη λιανικής) and B2B transactions require a tax invoice (τιμολόγιο), both transmitted to myDATA in near real time. Manual invoicing is unworkable past ~50 orders/day.

The Zunapro myDATA module:

• Auto-issues the correct invoice type the moment a You.gr order is created
• Integrates with AADE-certified e-invoicing providers (Epsilon Net, SoftOne, Entersoft, Cosmos Business Systems, Softecon)
• Generates credit notes automatically when a return is approved
• Produces monthly VAT summaries (24% / 13% / 6%) aligned with myDATA submissions
• Emails buyers a PDF copy and archives the XML for the legal 5-year retention window

Greek Legal Framework for You.gr Sellers

Selling on You.gr means selling under Greek and EU law. The non-negotiable obligations every tech retailer must respect are:

• VAT: standard 24%, reduced 13% (selected items), super-reduced 6% (books, pharmaceuticals); island-specific reductions apply where AADE has approved them
• AADE / myDATA: mandatory real-time e-invoicing for B2B and B2C
• GDPR & HDPA: EU General Data Protection Regulation plus the Hellenic Data Protection Authority — lawful basis, retention limits, breach notification within 72 hours
• 14-day right of withdrawal: distance-selling consumers can return without cause within 14 days of delivery
• 2-year legal warranty: mandatory minimum warranty on consumer electronics under EU directive 2019/771
• WEEE / REACH / CE: electrical and electronic equipment registration, chemical-substance compliance and CE-marking declarations are mandatory for the tech categories that dominate You.gr
• Consumer Protection Code (Law 2251/1994 as amended): pricing transparency, prohibited unfair commercial practices and clear T&Cs

Returns and Customer Service Workflow

Return rates on Greek tech marketplaces vary sharply by category: accessories sit at 15–25%, smartphones and computing at 3–6%, audio and wearables around 8–12%. Poorly handled returns directly damage your seller score.

Standard You.gr return flow:

1. Buyer opens a return request from the You.gr customer panel (within 14 days of delivery)
2. You.gr arranges pickup with the original carrier (ACS, Geniki, Speedex) or routes the buyer to a BoxNow locker drop-off
3. Parcel reaches your warehouse; you have 2 business days to inspect and approve/reject
4. On approval, You.gr refunds the buyer and you issue a credit note via myDATA
5. On rejection (e.g. visible misuse), you document evidence and the You.gr quality team arbitrates

The Zunapro returns module orchestrates the entire flow — incoming notification, inspection workflow, credit-note generation and refund reconciliation — without leaving the dashboard.
