e-shop.gr Integration: Marketplace API & Centralized Tech Sales Management

About e-shop.gr: History, Ownership & Market Position

Founding and Timeline (1998 – Today)

e-shop.gr launched in Athens in 1998, when Greek broadband penetration was below 1% — making it the country's first serious online-only consumer-tech retailer. While most contemporaries shifted to brick-and-mortar hybrids, e-shop.gr remained pure-online and founder-led for more than 25 years, building deep expertise in electronics merchandising, last-mile logistics and Greek consumer behavior. The brand became a household name for laptops, smartphones, TVs, gaming hardware and white goods.

In 2019, the company opened its catalog to third-party sellers and formally launched the e-shop.gr Marketplace, transitioning from a 1P-only retailer to a hybrid 1P + 3P platform. By 2024, the marketplace had attracted 800+ approved sellers and contributed a meaningful share of the platform's combined ~€350M Greek GMV. The Athens distribution center, paired with 3PL extensions, supports same-day metropolitan delivery and next-day nationwide reach.

e-shop.gr Ownership & Operating Structure

• e-shop.gr S.A. — Greek parent entity, founder-led for 25+ years, headquartered in Athens
• Own DC Athens — Primary fulfillment hub for 1P inventory and select 3P FBE-style consignment
• 3PL extensions — Capacity overflow and regional last-mile partnerships
• 12+ physical click&collect pickup points — Athens, Thessaloniki and other major urban centers
• Marketplace launched 2019 — 800+ sellers across electronics, IT, mobile, gaming, home appliances and photo

Position in Greek E-Commerce

e-shop.gr holds a distinctive position as Greece's pioneer pure-online tech retailer and one of the top three consumer-tech destinations alongside Public and Kotsovolos / e-commerce arms of brick-and-mortar chains. The platform's strength concentrates in consumer electronics, IT, mobile and gaming — categories where its 25-year merchandising heritage produces higher conversion rates than generalist marketplaces. For tech-focused B2B sellers, e-shop.gr is the most relevant Greek marketplace to prioritize.

e-shop.gr Sales Volume & Market Position (2024–2025)

Although e-shop.gr does not publish detailed annual reports, industry estimates and retail-tracking sources indicate the company runs ~€350M in combined Greek GMV (own retail + marketplace) in 2024. The marketplace channel, launched in 2019, contributes a growing share each year as the seller base expands beyond the original 1P catalog.

Year	Greece GMV (est.)	Active Sellers	Customers	Notes
2019	~€180M	Launch	~1.8M	Marketplace launched (3P expansion)
2022	~€270M	~500	~2.5M	Tech category lead, COVID-driven growth
2024	~€350M	800+	3M+	Own DC Athens + 3PL extensions
2025 (forecast)	~€400M	1,000+	3.4M	Premium Service expansion, BoxNow integration

Greek e-commerce has been growing at 15–20% annually, with consumer electronics as the largest single category. e-shop.gr's marketplace expansion strategy is to onboard specialist 3P sellers across electronics adjacencies — gaming peripherals, smart home, photography — categories where its 1P breadth has gaps. Joining the e-shop.gr marketplace is therefore one of the most targeted growth routes for B2B tech sellers in Greece.

Becoming an e-shop.gr Seller (2026 Rules)

1. Legal and Tax Requirements

To sell on e-shop.gr you need an active Greek tax registration (AFM) issued by AADE, plus mandatory myDATA enrollment for real-time e-invoicing. Sole proprietorships (atomiki epicheirisi), IKE, EPE and AE corporate forms are all eligible.

• AFM (Greek VAT number) — issued by AADE
• Tax certificate (current year) and entry in GEMI commercial registry (for legal entities)
• myDATA enrollment — mandatory AADE e-invoicing infrastructure
• Greek bank account (IBAN) — payouts are deposited here
• Brand documentation — trademark or authorized-distributor proof for branded electronics, photo and gaming categories
• GDPR / HDPA compliance — privacy notice and data-processing terms
• WEEE / REACH / CE compliance for electronics SKUs

2. e-shop.gr Marketplace Application

Apply via the official portal at e-shop.gr/marketplace. Approval typically takes 7–14 business days. Once approved you receive your seller ID, OAuth 2.0 client ID and client secret — the three values Zunapro needs to authenticate against the Marketplace API.

3. Product Listing and Content Rules

e-shop.gr enforces strict listing standards aligned with consumer-tech retail expectations:

• Title: 60–150 characters, brand + model + key specification (e.g. screen size, capacity)
• Images: White background, minimum 1000×1000px, up to 8 images, no watermarks or overlay text
• Description: HTML supported, minimum 250 characters with structured spec sheet
• Category mapping: e-shop.gr category ID + required attributes (capacity, color, energy class, connectivity)
• EAN / GTIN barcode: Mandatory for branded electronics — drives product-page matching
• Content score: Minimum 80/100 for the listing to surface in search and category browse

e-shop.gr Commission Rates (2026)

e-shop.gr commission rates are split into three category bands ranging from 4% to 17%. Greek VAT (24% standard, 13% reduced, 6% super-reduced), fulfillment fees and optional Premium Service charges are applied on top. Calculating gross-to-net margin before pricing is the most common mistake new marketplace sellers make. The three main bands break down as follows:

Net margin formula: Sale price − Commission − VAT − Premium Service fee (if used) − Shipping cost − Cost of goods = Net profit. The Zunapro pricing module runs this computation per SKU and per category automatically and blocks listings from dropping below your minimum-margin floor.

e-shop.gr Marketplace API — Technical Details

The e-shop.gr Marketplace API is a RESTful interface that lets approved sellers synchronize product, stock, order, price, shipping and return data programmatically. API base URL: https://api.e-shop.gr/marketplace/

API Authentication (OAuth 2.0)

The Marketplace API uses OAuth 2.0 client-credentials grant. Exchange your client_id and client_secret at the token endpoint to receive an access_token (Bearer), which is then passed in the Authorization: Bearer <token> header. Tokens expire and must be refreshed; rotating credentials every 6–12 months is recommended security practice.

Core Endpoint Groups

• Products API — Create, update and retire SKUs; category mapping; content-score lookup
• Inventory API — Stock and price synchronization (bulk endpoint up to 100 SKUs per request)
• Orders API — Order listing, status transitions, package creation and dispatch confirmation
• Shipment API — Generate ACS Courier / Geniki Taxydromiki / ELTA / Speedex / BoxNow labels and post tracking numbers back to e-shop.gr
• Returns API — Inspect, accept or reject return requests inside Greek 14-day withdrawal window
• Settlements API — Payouts, marketplace invoices and reconciliation
• Webhooks — Real-time callbacks on order, inventory and return events

Rate Limits and Error Handling

Marketplace API rate limit is approximately 10 requests per second per seller. When exceeded the API returns 429 Too Many Requests. Common error codes: 400 (invalid product payload), 401 (expired or invalid Bearer token), 404 (category or EAN not found), 500 (platform error — retry with backoff). The Zunapro connector handles token refresh, exponential-backoff retry, dead-letter queues and webhook dispatch out of the box.

Catalog & Feed Onboarding — Bulk Product Upload

Most B2B sellers reach e-shop.gr from an existing storefront or supplier catalog. Zunapro's catalog feed onboarding module reads your product source (Shopify API, WooCommerce REST, OpenCart XML, custom CSV or supplier feed), normalizes it to e-shop.gr's schema, and publishes the catalog at scale — getting thousands of SKUs listed within minutes instead of days.

e-shop.gr Listing Schema (Required Fields)

Key fields the Marketplace API expects per SKU:

• productMainId — Master product code (groups variants such as colors or capacities)
• brand, title, modelCode, stockCode, ean
• categoryId (e-shop.gr category) + attributes (capacity, color, energy class, connectivity, refresh rate)
• quantity (stock), listPrice, salePrice, vatRate (24 / 13 / 6)
• shippingProfileId, warehouseId, weight, dimensions
• images (1–8 URLs), description (HTML), weeeCode, energyLabel

From Supplier Catalog to e-shop.gr

Greek electronics distributors and Pan-European suppliers commonly publish daily CSV or XML feeds. The Zunapro feed module:

1. Polls the supplier feed (hourly / daily cron)
2. Learns category mapping — first-time mapping is manual; subsequent updates auto-resolve
3. Normalizes brand, capacity, color, energy class and connectivity attributes
4. Applies your margin and Greek VAT on top of the wholesale price
5. Tracks stock — out-of-stock SKUs at supplier are auto-deactivated on e-shop.gr
6. Publishes via the Marketplace API

Fulfillment Options — e-shop Premium Service, Own DC & 3PL

e-shop.gr supports two fulfillment models for marketplace sellers: seller-fulfilled (you ship from your own warehouse) and e-shop Premium Service — the platform's express delivery program backed by e-shop.gr's own Athens distribution center plus 3PL extensions. Premium Service is the closest analog to Amazon FBA in the Greek market.

e-shop Premium Service Advantages

• Same-day Athens metro / next-day nationwide — leveraging ACS Courier partnership
• Higher search and category placement — Premium-flagged listings outperform standard offers
• Click&collect at 12+ physical pickup points — Athens, Thessaloniki and other major centers
• "Order today, receive tomorrow" badge — typically lifts conversion 15–25%
• Returns handled by e-shop.gr — including reverse logistics through ACS Courier

Premium Service Cost Considerations

• Storage: monthly volumetric fee per pallet position at the Athens DC
• Pick & pack: per-unit handling fee, tiered by product weight class
• Returns processing: per-return inspection fee
• Commission uplift: standard category commission + ~1–2% Premium Service surcharge

Premium Service becomes cost-efficient for sellers above approximately 500 orders / month with high attach-rate SKUs (TVs, washing machines, smartphones). Lower-volume sellers should start with seller-fulfilled and graduate into Premium once order density justifies the storage fee.

Seller Performance Score & Cancellation Rules

e-shop.gr scores each seller on a 1–10 scale; this score directly drives buy-box placement and search visibility. The main factors that reduce the score:

• Cancellation rate — Out-of-stock cancellations carry the heaviest penalty; above 2% triggers a warning, above 5% risks marketplace suspension
• Late dispatch — Orders not handed to the courier within the promised handling window
• Return rate — Above category baseline (electronics 5–10%, lifestyle tech 10–15% is normal)
• Customer reviews — Must stay above 4.0 stars rolling average
• Response time — Buyer messages must be answered within 24 hours

Zunapro's real-time stock synchronization reduces cancellation risk by approximately 90% — the moment a unit sells on your storefront, another marketplace or warehouse, the e-shop.gr listing decrement is pushed immediately.

Advertising, Promotions & Smart Pricing

e-shop.gr Promotional Mechanics

• Featured Listings — Paid placement in search and category browse (CPC-based)
• Smart Campaigns — Algorithmic budget allocation across category trees
• Brand storefront banners — Display and brand-page modules
• Premium Service promotions — Discount campaigns reserved for Premium-fulfilled SKUs

Smart Pricing (Repricer)

Buy-box competition on e-shop.gr is intense in consumer electronics — the same TV or smartphone is frequently offered by 8–15 sellers. The buy box typically goes to the lowest price among sellers with a 9+ seller score, with Premium Service offers favored. The Zunapro repricer auto-adjusts prices against competitors in seconds and never crosses your minimum-margin floor.

myDATA E-Invoicing & AADE Compliance

Greek tax law requires every seller — B2C and B2B — to issue compliant electronic invoices and transmit them in real time to AADE myDATA. Manual invoicing is not viable above ~50 orders per day, and non-compliance triggers AADE fines and marketplace deactivation.

The Zunapro myDATA module:

• Auto-issues a compliant invoice the moment an e-shop.gr order is captured
• Submits the invoice to AADE myDATA in real time (B2C retail and B2B)
• Generates credit notes automatically on returns within the 14-day withdrawal window
• Provides monthly VAT reporting at 24% / 13% / 6% rates
• Delivers PDF invoices to customers via email and SMS in EN or EL

Shipping Integration — ACS Courier, Geniki Taxydromiki, ELTA, Speedex, BoxNow

e-shop.gr's preferred courier partner is ACS Courier, used for the bulk of next-day deliveries and Premium Service dispatches. Sellers can also dispatch through Geniki Taxydromiki, ELTA Hellenic Post, Speedex and BoxNow parcel lockers — each integrated with the Marketplace API for label printing and tracking number return.

Zunapro's multi-carrier module picks the optimal courier per order based on parcel weight, destination region (Athens, Thessaloniki, islands), customer preference (home delivery vs. BoxNow locker) and SLA window — then prints the label and posts the tracking number back to e-shop.gr automatically.

Returns & Customer Service — 14-Day Withdrawal & 2-Year Warranty

Greek consumer law guarantees buyers a 14-day right of withdrawal on distance-sold goods and a 2-year statutory warranty on consumer products — strictly enforced by HDPA and the consumer protection authority. Return rates run approximately 5–10% in electronics, 10–15% in lifestyle tech and 2–5% in large appliances.

Standard e-shop.gr return flow:

1. Customer opens a return request from the e-shop.gr account within the 14-day window
2. ACS Courier collects the parcel free of charge (1–3 business days)
3. e-shop.gr or seller warehouse inspects and routes the case
4. Seller approves or rejects within 1–3 business days
5. On approval, the refund is issued to the customer's original payment method

The Zunapro returns module tracks every step, alerts you in-panel and auto-generates the AADE myDATA credit note for approved customer returns.
