Galaxus Integration: Marketplace API, Migros Ecosystem & Unified Store Management

About Galaxus: History, Ownership and Market Position

Founding and Timeline (2012 – Today)

Galaxus was launched in 2012 by Florian Teuteberg, Marcel Dobler and Oliver Herren as the general-merchandise sister site to Digitec, the IT and electronics retailer they had co-founded in 2001. The objective was simple: extend Digitec's customer-obsessed catalogue model — community reviews, transparent pricing and editorial content — beyond consumer electronics into home, fashion, beauty, sports and food. The company is headquartered in Zürich, with its main fulfillment centre in Wohlen, Aargau.

In 2015, the Migros Genossenschaftsbund — Switzerland's largest retail cooperative and parent of the Migros supermarket chain — acquired a majority stake, and by 2018 the company became a wholly-owned subsidiary operating as Digitec Galaxus AG. Florian Teuteberg continues to lead the combined business as CEO. International expansion into Germany (galaxus.de) launched in 2018, followed by Austria (galaxus.at), positioning Galaxus as a credible DACH challenger to Amazon and Otto.

Galaxus Ownership Structure (2026)

• Migros Genossenschaftsbund (Migros Group) — 100% parent organisation since 2018, Switzerland's largest retail cooperative
• Digitec Galaxus AG — operating entity headquartered in Zürich
• Florian Teuteberg — Chief Executive Officer, co-founder
• Marcel Dobler — co-founder, now Swiss National Councillor (FDP)
• Oliver Herren — co-founder, Chief Innovation Officer

Position in the Swiss E-Commerce Market

As of 2024, Digitec Galaxus group reports CHF 3.5B+ in combined annual GMV, with CHF 2.5B+ attributable to the Swiss market alone — making it the country's #1 online retailer ahead of Brack, Microspot and Amazon CH. Galaxus and Digitec together account for an estimated 20–25% of Switzerland's total online retail spend, and Galaxus has been the fastest-growing general-merchandise marketplace in the German-speaking region for three consecutive years.

Galaxus Market Size and Growth Trajectory (2024–2025 Data)

Over the last five years, Galaxus has consistently outpaced overall Swiss e-commerce growth. The combined Digitec Galaxus business grew its Gross Merchandise Value (GMV) at a 15–25% annual clip while the broader Swiss online retail market expanded only 5–8%.

Year	Group GMV (CHF)	Orders	Active Customers	3P Sellers
2020	~CHF 1.9B	9.2M	3.4M	1,800
2022	~CHF 2.7B	13.1M	4.3M	3,500
2024	~CHF 3.5B	16.4M	5M+	6,000+
2025 (forecast)	~CHF 4.1B	19M	5.6M	7,500

Growth is driven by the cross-border DACH model (a single seller account reaches CH, DE and AT consumers), the proprietary Galaxus Express delivery network, and the editorial-first product page format that consistently outperforms competitor marketplaces on conversion. Onboarding as a Galaxus marketplace seller is the most efficient channel for European brands to enter the affluent Swiss consumer market.

Opening a Galaxus Seller Account (2026 Requirements)

1. Legal and Tax Requirements

To sell on Galaxus you need an active legal entity in Switzerland (AG, GmbH or sole proprietorship registered in the Handelsregister) or an EU/EEA company with Swiss VAT registration. MwSt registration with the ESTV (Swiss Federal Tax Administration) is mandatory once Swiss-sourced turnover exceeds CHF 100,000 annually, and QR-Rechnung compliant invoicing has been mandatory since October 2022.

• Handelsregister entry (Commercial Register, current year)
• UID number (Unternehmens-Identifikationsnummer)
• MwSt registration certificate issued by ESTV
• CHF IBAN for payouts (foreign IBANs are accepted with SEPA-style conversion)
• QR-Rechnung capable invoicing system — mandatory since October 2022, replaced ISR orange payment slip
• nFADP-compliant privacy notice (revised Federal Data Protection Act 2023, supervised by the EDÖB Data Protection Commissioner)
• Brand authorisation (for selective categories such as beauty, electronics and luxury — also checked against the KIVE counterfeit database)

2. Application via the Galaxus Seller Portal

Submit your application at Official Galaxus Marketplace Seller Application. Approval typically takes 14–21 business days as the Galaxus partner team manually reviews tax documents, brand authorisations and a sample product feed. Once approved, you receive your Supplier ID, OAuth 2.0 client ID and client secret — the credentials required by any third-party connector or ERP integration.

3. Product Listing and Content Standards

Galaxus enforces a strict editorial bar on product content because each PDP is treated as long-form content, not a templated catalogue page:

• Title: 60–150 characters, brand + model + key attribute, no marketing claims
• Imagery: white background, minimum 1500×1500px, up to 12 photos, no overlays or watermarks
• Description: structured HTML, minimum 300 characters, multilingual (DE/FR/IT/EN strongly recommended)
• Category mapping: Galaxus category ID + attribute set (colour, size, material, energy class)
• GTIN / EAN barcode: mandatory for branded products, accelerates catalogue matching
• Content score: editorial review by Galaxus partner team — below threshold pages are not indexed in search

Galaxus Commission Rates (2026)

Galaxus commission ranges from 4% to 17% depending on the category, plus Swiss MwSt (8.1% standard, 2.6% reduced, 3.8% accommodation) and any fulfillment fees. Net-margin modelling before launch is the most common mistake new sellers make — Swiss consumers expect competitive pricing, but Swiss cost structures (logistics, returns, MwSt) are materially higher than EU benchmarks. The three main commission bands:

Net-margin formula: Sale price − Commission − MwSt − Fulfillment fee − Shipping − Cost of goods = Net profit. Zunapro's pricing module runs this calculation per SKU per category in real time and blocks any listing that would drop below your configured minimum-margin threshold.

Galaxus Marketplace API — Technical Reference

The Galaxus Marketplace API is a RESTful interface that allows approved sellers to synchronise products, inventory, pricing, orders, shipments and returns programmatically. Base URL: https://api.galaxus.ch/marketplace/. Full developer documentation lives at developer.galaxus.ch.

API Authentication

The Galaxus Marketplace API uses OAuth 2.0 client-credentials flow. You exchange your client_id and client_secret for a bearer access token (typically 1-hour TTL) and send it via the Authorization: Bearer <token> header. Refresh-token rotation and IP allow-listing are supported for production deployments.

Core Endpoint Groups

• Products API — create, update, retire listings, map categories, validate attribute completeness
• Inventory API — bulk stock and price updates (up to 100 SKUs per request)
• Orders API — list orders, update fulfillment status, generate packing slips
• Shipments API — request carrier labels (Galaxus Express, Die Post, DPD Schweiz, Quickpac), push tracking numbers
• Returns API — query return requests, approve or dispute
• Settlements API — payouts, commission statements, MwSt reconciliation reports
• Webhooks — push notifications on order, inventory, return and Smiley-rating events

Rate Limits and Error Handling

The Galaxus Marketplace API enforces a soft limit of approximately 10 requests per second per seller, with burst tolerance. Exceeding the limit returns 429 Too Many Requests. Common error codes: 400 (invalid payload), 401 (expired bearer token), 403 (category not authorised for seller), 404 (SKU or category not found), 409 (concurrent inventory write conflict), 500 (upstream Galaxus error — retry with exponential backoff). The Zunapro integrator implements retry-with-jitter, idempotency keys and a dead-letter queue automatically.

Galaxus Catalogue Feeds — Bulk Onboarding of Existing Catalogues

For brands and distributors with thousands of SKUs, manual entry through the seller portal is impractical. Zunapro ingests your existing CSV, XML, JSON or BMEcat product feeds — common for European distributors and ERP exports — and transforms them into the Galaxus Marketplace schema with category mapping, attribute normalisation and multilingual enrichment.

Galaxus-Compatible Schema Fields

Key fields expected by the Galaxus product import pipeline:

• productGroupId — master grouping for variants (size, colour, capacity)
• brand, title, manufacturerArticleNumber, supplierSku, gtin
• categoryId (Galaxus taxonomy) + attributes (colour, size, material, energy class)
• availableStock, listPriceChf, salePriceChf, vatRate (8.1 / 2.6 / 3.8)
• carrier, warehouseId, handlingDays
• images (1–12 URLs), descriptionDe, descriptionFr, descriptionIt, descriptionEn

Distributor and ERP Feed Ingestion

Most European distributors (notably ITscope, Tech Data, Also, Wynit) and ERP systems (SAP, Microsoft Dynamics, Odoo, Abacus) expose nightly catalogue feeds. The Zunapro feed module:

1. Polls the source URL on a configurable cron (hourly or daily)
2. Learns category mappings — first run is manual, subsequent runs auto-classify
3. Normalises brand, attributes and units against the Galaxus taxonomy
4. Applies pricing rules — margin uplift, MwSt, FX conversion if source is in EUR
5. Tracks supplier stock — out-of-stock SKUs are auto-deactivated within minutes
6. Pushes to Galaxus via the Marketplace API with idempotency keys

Galaxus Fulfillment — Warehouse, Carriers and Galaxus Express

Galaxus operates its own fulfillment centre in Wohlen (Aargau), complemented by a network of third-party logistics partners across the DACH region. Sellers can self-fulfill from their own warehouse or store inventory in the Galaxus facility for faster delivery service-levels and the prized Galaxus Express badge.

Galaxus Fulfillment Benefits

• Galaxus Express same-day / next-day delivery — premium placement in search and category pages
• Higher buy-box win rate — Galaxus Express badge ranks ahead of self-fulfilled offers
• Returns handled centrally — Galaxus customer support manages the entire reverse logistics flow
• "Delivered tomorrow" badge on PDPs typically lifts conversion 15–25%
• Zero packaging overhead — Galaxus operations team picks, packs and ships

Carrier Network

Whether you self-fulfill or use Galaxus warehousing, the supported carrier network covers the entire CH/DACH footprint:

• Galaxus Express — proprietary same-day / next-day delivery in major Swiss cities
• Die Post (Swiss Post) — nationwide standard and priority parcels, PostFinance returns
• DPD Schweiz — pan-DACH cross-border distribution, B2B specialty
• Quickpac — economical urban last-mile, growing rural coverage

Galaxus warehousing makes economic sense once you exceed roughly 500 orders per month. Below that threshold, self-fulfillment plus Zunapro's automated label generation usually produces a better unit-economics outcome.

Galaxus Smiley Rating, Buy Box and Seller Performance

Unlike most marketplaces, Galaxus does not use a generic 5-star system. The proprietary Smiley rating aggregates customer satisfaction, delivery accuracy, response time and return rates into a single sentiment score that directly drives buy-box share and category visibility across Galaxus and Digitec. The factors that move the score:

• Cancellation rate — stock-out cancellations are penalised heavily; above 2% triggers warnings, above 5% threatens suspension
• Late shipment rate — orders not handed to the carrier within the handling-time SLA
• Return rate — measured against category benchmarks (fashion 25–35% is normal, electronics under 8%)
• Customer review tone — Galaxus uses natural-language processing on free-text reviews, not just stars
• Response time — partner-portal messages must be answered within 24 hours on business days

Zunapro's real-time inventory sync typically reduces cancellation rate by 90% — the moment a SKU sells on your storefront or another marketplace, the Galaxus listing reflects the new stock level within seconds.

Galaxus Advertising, Promotions and Repricing

Galaxus Advertising Surfaces

• Sponsored Products — top placements in search and category pages (CPC, CHF per click)
• Galaxus Algorithmic Ads — automated budget optimisation across surfaces
• Brand Store advertising — banners, display and editorial collaborations
• Galaxus Express promotional bursts — campaign discounts for Express-eligible SKUs

Algorithmic Repricing

The Galaxus buy-box contest is rigorous when multiple sellers list the same EAN. The winner is typically the offer combining a competitive price, a strong Smiley score and Galaxus Express eligibility. Zunapro's repricer module adjusts your prices against competitor offers within seconds while respecting your configured minimum-margin floor.

QR-Rechnung E-Invoicing and ESTV Compliance

Every seller invoicing Swiss customers must issue QR-Rechnung compliant invoices — the standard that fully replaced the legacy ISR (Einzahlungsschein) orange payment slip in October 2022. Invoices must include the Swiss QR code with IBAN, structured creditor reference and amount, and must be filed in accordance with ESTV (Swiss Federal Tax Administration) rules for the relevant MwSt rate (8.1% standard, 2.6% reduced, 3.8% accommodation). For high-volume Galaxus sellers, manual generation is not viable.

The Zunapro QR-Rechnung module:

• Auto-generates QR-Rechnung PDFs the moment a Galaxus order arrives
• Validates the Swiss QR code against the SIX Interbank Clearing specification
• Applies the correct MwSt rate per line item (8.1 / 2.6 / 3.8)
• Issues automatic credit notes for returns and refunds
• Produces monthly MwSt declaration packets aligned with ESTV reporting cycles
• Emails the invoice PDF to the customer with optional SMS notification
• nFADP compliant — customer data handled under the revised Federal Data Protection Act (2023) supervised by the EDÖB

Carrier Integration — Galaxus Express, Swiss Post, DPD Schweiz, Quickpac

Galaxus orders default to Galaxus Express when the seller has opted into the program; otherwise sellers may choose Die Post (Swiss Post), DPD Schweiz or Quickpac per shipment. Cross-border CH/EU shipments require correct customs declarations — the Zunapro panel pre-fills HS codes, country of origin and commercial-invoice values automatically.

The Zunapro multi-carrier module selects the most cost-effective carrier per order based on weight, destination, service-level requirement and customer preference, prints the label, and pushes the tracking number back to Galaxus through the Shipments API.

Galaxus Returns and Swiss Consumer Law

Since Switzerland is not an EU member, the EU 14-day right of withdrawal does not apply. The Galaxus standard return window is 7 days for most categories, with a 2-year statutory warranty under the Swiss Code of Obligations (Obligationenrecht, OR). Return rates are highest in fashion (25–35%) and lowest in electronics (4–8%) and home goods (10–14%).

Galaxus standard return workflow:

1. Customer files a return request through the Galaxus account (within 7 days of delivery)
2. Galaxus issues a prepaid return label via Die Post or DPD Schweiz (1–3 business days)
3. Galaxus returns centre inspects and either restocks or forwards to the seller
4. Seller approves or disputes the return within 1–3 business days
5. Approved refund is credited to the customer's Galaxus wallet or original payment method

The Zunapro returns module tracks every state transition, notifies the seller in real time, and issues a QR-Rechnung credit note automatically on approval.
