What is Shopify and why do online stores across Europe use it?

Shopify is one of the most widely used e-commerce platforms in the world - over 4.6 million active stores, running in more than 175 countries. For Bulgarian merchants the platform solves three main problems at once: hosting, secure payments and app ecosystem.

Key features

Cloud-based - no need for your own server, VPN or developer to maintain the infrastructure. Shopify handles uptime, security patches and PCI compliance.

Full REST + GraphQL API - one of the most stable and best-documented APIs in the e-commerce industry. That is exactly what makes it ideal for automation.

App marketplace - over 8,000 apps for marketing, analytics, POS systems and logistics. The BigArena integration lives right here.

When Shopify is the right choice for you

You do between 50 and 5,000 orders per month. Under 50 - the platform is overkill; over 5,000 - you will probably want an enterprise-tier plan or a custom stack. In this range Shopify delivers the best value for money.

You sell in several countries. Multi-currency, multi-language and regional pricing all work in a single store, without cloning.

You want a fast start. From signup to your first order - typically 2-8 days (when stock and photos are ready). No self-hosted platform comes close.

How the integration between Shopify and BigArena works

No CSV file juggling, no copying orders into Excel sheets, no manual statuses. Our integration is built on the official Shopify Fulfillment Service API and runs over webhooks + REST API - the standard for real-time automation.

Customer places an order

The buyer completes checkout in your Shopify store. Pays (COD, card, wallet).

Webhook notifies BigArena

Shopify fires the orders/create webhook. Our endpoint receives it, validates it and creates a fulfillment task in the BigArena platform.

Picking, packing, courier

The warehouse team picks the goods, packs them with your branded materials and applies the label from your chosen courier.

Fulfillment + tracking back

BigArena pushes POST /fulfillments with the tracking number. The buyer gets the automatic Shopify email with tracking details.

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

The setup process is standardised across the Shopify stores we run. No developer and no specialist knowledge needed: our team connects the store in about half an hour.

Request + kick-off call (30 min)

You fill in the form below. Our sales rep calls you within 1-2 hours for a kick-off call - we discuss your assortment, volumes, the couriers you work with and any specific requirements (packaging, stickers, instructions).

We create your BigArena platform account

You get access to your own admin panel with an overview of orders, stock and stats. This is where you see everything in real time. From the same panel you manage every Shopify store you have connected.

You connect your Shopify store

In the BigArena platform go to Integrations → Shopify. Enter your store URL (e.g. your-shop.myshopify.com) and approve access through the standard Shopify OAuth flow. We register BigArena as a fulfillment service in your store.

Ship the goods + go live

Send the stock to your chosen warehouse (we can handle inbound logistics too). Add the SKUs in the BigArena platform and record their stock levels. From the moment the first delivery arrives and is checked in, every new order flows into the pipeline automatically.

What you get with the BigArena integration

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

Real-time stock sync

Stock levels in Shopify update every time goods come in or go out. No overselling, no manual corrections after fulfilment.

Multi-store support

Connect an unlimited number of stores under one company account, on 5+ platforms at once, for example Shopify and WooCommerce side by side, all from one inventory. Each store can have its own bank account for COD payouts, so you see the COD flow and P&L per store. No fee for extra stores and free setup.

Same-day pickup for orders before 14:00

Every order that comes in before 14:00 local business time is packed and handed to the courier the same day. Buyers see the tracking that evening.

International shipping from 8 warehouses

Your store integration sends each order to the warehouse you choose, usually set once per country. You decide where and in how many warehouses to keep stock; most clients use 1-2.

Cash on delivery in 24 countries

Full COD support through local couriers. The COD payment status syncs back to your Shopify orders, and you choose the payout currency and frequency in the panel, from once a month up to daily. In Romania, payouts are up to twice a week.

Returns handling

The buyer returns an order → our warehouse checks the goods and returns them to stock or sets them aside as defective. You decide the refund in the BigArena platform, without touching the goods.

Cash on delivery for Shopify stores

Your Shopify customers can pay cash on delivery in 24 European countries. The courier collects the money at the door, the payment status comes back to the order in Shopify, and the payout reaches you on the schedule you set. We charge no COD collection fee, only the courier's fee applies, if the courier charges one.

The buyer chooses cash on delivery

At checkout the buyer picks cash on delivery and the courier they prefer. Orders received by 14:00 are packed and handed to the courier the same day.

The payment status syncs to Shopify

When the courier collects the money, the COD payment status syncs back to the order in your Shopify store. You see which orders are paid without checking courier reports.

Payouts on your schedule

In the panel you choose how often you get paid, from monthly up to daily (Romania up to twice a week), and in which currency. When we convert, the exchange rate is shown.

Refused parcels come back

Refused and unclaimed parcels return to our warehouse. We open them, scan every product and process them in 1-4 working days, usually 2, so good items go back on sale.

Countries with cash on delivery: Bulgaria, Romania, Greece, Hungary, Serbia, Poland, Czechia, Slovakia, Croatia, Slovenia, Bosnia and Herzegovina, Montenegro, North Macedonia, Lithuania, Latvia, Estonia, Cyprus, Malta, Ireland, Germany, Austria, Italy, Spain and Portugal. More in our guide to cash on delivery in Europe and on how we handle returns.

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 Shopify integration

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

Does it work with the Shopify Basic, Shopify, Advanced and Plus plans?

Yes, the integration works with all standard Shopify plans (Basic, Shopify, Advanced) and with Shopify Plus. We use the publicly documented API endpoints available on every plan. For Plus stores we also take advantage of Flow automations for more complex business rules.

Can I keep part of my assortment with me and part with BigArena?

Yes. Shopify supports multi-location inventory. You decide which SKUs live in the BigArena warehouse (fulfillment service location) and which stay in your own warehouse (regular location). Orders for your SKUs go to you, orders for BigArena SKUs come to us.

What if I already use another fulfillment app in Shopify?

No conflict. You can have multiple fulfillment services running in parallel in Shopify - each responsible for different products. We help with the migration: we copy the SKUs into the BigArena platform, sync the stock and test with 5-10 orders before the full switchover.

How are stickers, packaging and the branded experience handled?

During setup you upload your branded materials (boxes, stickers, thank-you cards, flyers). We store them and use them automatically when packing your orders. For specific rules (for instance "include a flyer only on orders above 50 BGN") - we configure it free of charge in the BigArena platform.

How do tracking numbers sync back into Shopify?

After packing, the BigArena platform automatically sends POST /admin/api/fulfillments with the tracking number and courier. Shopify marks the order as fulfilled and sends the standard "Your order is on the way" email to the buyer with the tracking link. The buyer sees live statuses (from the courier system) via the Shopify tracking page.

How fast is pickup and delivery?

Orders placed by 14:00 business time, are packed and handed to a courier the same day. Delivery time depends on the courier and destination. We work with Speedy, Econt, ELTA, InPost, PPL, Packeta and 40+ other couriers.

Can my Shopify store offer cash on delivery in Europe?

Yes, in 24 countries: Bulgaria, Romania, Greece, Hungary, Serbia, Poland, Czechia, Slovakia, Croatia, Slovenia, Bosnia and Herzegovina, Montenegro, North Macedonia, Lithuania, Latvia, Estonia, Cyprus, Malta, Ireland, Germany, Austria, Italy, Spain and Portugal. The buyer chooses cash on delivery at checkout, the courier collects the payment and the COD payment status syncs back to the order in Shopify. We charge no COD collection fee, only the courier's fee applies, if the courier charges one.

How and when do I receive the cash on delivery money?

You choose the payout frequency in the BigArena panel, from monthly up to daily (in Romania up to twice a week), and the currency you want to be paid in. We collect local currencies from the couriers and convert them, with the exchange rate shown. Refused and unclaimed parcels come back to our warehouse and are processed in 1-4 working days, usually 2.

Will I pay more than if I do fulfillment myself?

It often works out cheaper once you include the hidden expenses (warehouse rent, electricity, staff, courier contracts without volume discounts, accounting, sick leave, the value of your own time). We run a detailed calculation on the kick-off call.

If I want to switch couriers - do I need to reconfigure Shopify?

No. Couriers are managed from the BigArena platform, not from Shopify. Your end customer picks the courier at checkout from the couriers you have enabled, and Shopify simply receives the tracking number and courier.

Do you handle food, supplements and cosmetics?

Yes. All our warehouses have food certification for handling food, food supplements and cosmetics. We follow FEFO (first expired, first out) and batch control - a must for regulated industries.

What happens during peak season (Black Friday, Christmas)?

We scale automatically. During peak we add shifts and extra staff in the affected warehouses (usually Plovdiv and Sofia carry the biggest volumes). We handle up to 20,000 orders per day without any pickup delay.
