- Shopify Fulfillment Integration
Fulfillment for Shopify stores - automatic sync in 24 hours.
We connect your Shopify store to 7 warehouses across Europe in under 15 minutes. Every new order is picked, packed and handed to a courier the same day, while statuses, tracking and stock levels sync back to Shopify automatically. No more CSV exports, no manual entry - end-to-end automation. The integration is completely free - you give us access to the platform and within 2 to 10 hours it is ready to run.
What is Shopify and why is it a popular choice for online stores in Bulgaria?
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 under 3 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 (usually within 2 hours), 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.
Live in under 24 hours - 4 steps from zero to your first processed order
The setup process is standardised across the 60+ Shopify stores we currently run. No developer, no specialist knowledge - just 15-20 minutes of your time for configuration.
Request + kick-off call (30 min)
You fill in the form below. Our sales rep calls you within 2 business 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 Shopify stores under a single BigArena account. Handy for brands with separate stores for BG/EU/US or for different product lines.
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 7 warehouses
We route the order to the warehouse closest to the buyer - Bulgaria, Romania, Slovakia, Serbia, Greece. Shorter delivery times, lower cost, happier customers.
Cash on delivery in 28 countries
Full COD support through local couriers. A must for the Bulgarian market and critical for Romania and Serbia.
Returns handling
The buyer returns an order → our warehouses inspect the goods (photos) and decide refund vs return-to-stock. You see everything in the BigArena platform without touching the goods.
Transparent pricing - you only pay for what you actually use
No monthly subscriptions, no deposits, no minimum volumes. Three components, each billed on real usage.
Pay-as-you-use model
Every Shopify store we onboard gets a quote tailored to its average volumes, average parcel weight and the courier network it uses.
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: BG (1-2 days), CS/RO/SK (2-4 days), rest of the EU (3-6 days). We work with Speedy, Econt, ELTA, InPost, PPL, Packeta and 40+ other couriers.
Will I pay more than if I do fulfillment myself?
It works out cheaper - typically 20-40% below your in-house fulfillment cost 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. If you decide "I want orders over 5 kg to go via Econt and the rest via Speedy" - you make the change in the BigArena platform and it takes effect from the next order. Shopify does not notice - it simply receives a tracking number and courier.
Do you handle food, supplements and cosmetics?
Yes. All our warehouses are certified by BFSA (the Bulgarian Food Safety Agency) for handling food, food supplements and cosmetics. We follow FIFO rotation by expiry date 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 5,000-10,000 orders per day without any pickup delay.
