What is Magento and why is it a popular choice?

Magento is one of the most widely used e-commerce platforms. For Bulgarian merchants it solves specific business needs.

Key features

Magento (now Adobe Commerce after the Adobe acquisition in 2018) is an enterprise-grade e-commerce platform. Over 250,000 active stores globally and dominant in B2B, luxury brands and multi-brand operations with high volumes.

Self-hosted or Adobe Commerce Cloud (managed). Full control over performance, security and customisations. Needs serious DevOps care but delivers uncompromising flexibility.

Native REST API + GraphQL (Magento 2.3+) + Async API. The richest API surface in online commerce.

When Magento is the right choice

You do 500+ orders per day or you have B2B customers. Magento is incredibly powerful for B2B: companies, negotiated pricing, credit terms, quote system, punch-out catalogs.

You sell in several countries with different taxes, currencies and languages. Native multi-store and multi-website architecture - one install serves BG/RO/GR stores with different catalogs and checkout rules.

You have a developer team or an agency partner. Magento is an investment - from install to performance tuning it is a serious commitment. For simpler use cases WooCommerce or Shopify are a better fit.

How the integration between Magento and BigArena

No CSV file juggling, no copying orders, no manual statuses. Real-time automation via the official Magento API mechanisms.

Customer places an order

The buyer completes checkout in Magento. Pays (card, COD, wallet, credit/quote for B2B). Magento sets the order state to processing.

The order reaches BigArena

The integration picks up every new Magento order and sends it to the BigArena platform over a secure API.

MSI selects the source, the fulfillment team handles it

The order goes to the BigArena warehouse you choose, usually set once per country. The BigArena warehouse team picks, packs and hands the order to a courier.

Shipment + tracking sync back

BigArena creates the shipment in Magento via REST API with the tracking number, courier code and tracking URL. Magento sends the shipment confirmation email automatically.

Connected in about half an hour - 4 steps to your first processed order

No developer, no specialist knowledge.

Request + tech kick-off call (60 min)

You fill in the form. A sales + tech rep call within 1-2 hours. We discuss your Magento version, install architecture (self-hosted/cloud), custom modules, volumes and B2B/B2C mix.

We connect the store in about half an hour

You give us API access to your Magento store and our team sets up the integration in about half an hour. Nothing to install on your server.

We set up the MSI sources

We create BigArena inventory sources in Magento MSI for each of our warehouses, so stock is visible per warehouse.

Migration + go live

When migrating from another fulfillment provider - we export the unfulfilled orders, map the SKUs and sync inventory. We test with 5-10 orders. Then we go fully live.

What you get with the BigArena integration

Features built specifically for Magento stores - not generic descriptions, but concrete value.

MSI Multi-Source Inventory

Native Magento 2 MSI support. Every BigArena warehouse is a separate source. Each order goes to the warehouse you choose, usually set once per country.

Multi-store, multi-warehouse

One install serves BG/RO/GR stores with different catalogs, currencies and checkout rules. Each store has its own warehouse routing.

Custom order attribute sync

Passes any custom order attributes (gift message, special instructions, B2B PO number) through to the BigArena platform for the packing team.

Transparent pricing - you only pay for what you actually use

No deposits, no minimum volumes. Three components, each billed on real usage.

Pay-as-you-use model

Every Magento store we onboard gets a quote tailored to its average volumes, average parcel weight and the courier network it uses.

Storage

No lock-ins, no monthly minimums.

Pick & Pack

Price after an individual quote: it depends on weight, destination, items per order and handling.

Courier

Negotiated rates with 40+ couriers.

Frequently asked questions about the Magento integration

The answers we most often give to Magento owners on the first call.

Which Magento versions does the integration work with?

Official support for Magento 2.3+ and every Adobe Commerce version. For Magento 1 (legacy) we can do it case by case via a custom API bridge - we do not recommend Magento 1 for new projects.

Does it work with Adobe Commerce Cloud?

Yes, fully compatible. The integration connects through the Adobe Commerce API, so nothing is installed in your Cloud environment. It works with all ACC infrastructure specifics (redis, varnish, elasticsearch).

How is a multi-website setup handled?

Each Magento website can have its own BigArena inventory sources or shared ones. You choose which warehouse handles the orders of each store, usually set once per country.

Can I use Magento MSI in parallel with other fulfillment sources?

Yes. BigArena warehouses register as additional MSI sources. Your own warehouse stays as a company source. Magento picks the source automatically based on priority or available quantity.

How are returns handled in Magento?

The standard RMA flow in Magento (or a third-party RMA extension) notifies BigArena via an event. The warehouses inspect the returned goods and propagate the refund/return-to-stock decision back into Magento.

How fast is the sync between Magento and BigArena?

Real-time via Magento events: orders reach the warehouse and shipment + tracking go back into Magento in real time.

Can I migrate from another fulfillment partner with no downtime?

Yes. We work in phases: first stock sync, then testing with 5-10 orders in parallel, then a full cutover. Typically 2-8 days with no service interruption.

Do you handle food, supplements and cosmetics?

Yes. All our warehouses are certified for food, supplements and cosmetics by the food safety authority of their country. We follow FEFO (first expired, first out) and batch control - critical for regulated Magento B2B customers.
