We bring your brand's digital operations together and connect every process into a single flow. By integrating your Shopify store with ERP, accounting, invoicing, shipping, returns and CRM systems, we eliminate operational complexity and make your workflow automated, error-free and sustainable. Our core strength is building custom Shopify apps tailored to your store.
As an experienced partner working with Shopify brands in Türkiye, we use the Admin API, Storefront API, Shopify Functions and webhook infrastructure to build custom app solutions for every need that off-the-shelf apps cannot meet. From payment infrastructures to shipping processes, ERP integrations to marketing automation — we unite everything in a single ecosystem.
We bring your brand's digital operations together into a single flow. By integrating your ERP, accounting, shipping, CRM and marketing systems with Shopify, we also build custom apps for your store where off-the-shelf solutions fall short.
Every order in your Shopify store runs in full sync with your payment and shipping processes. Each transaction can be tracked and managed in real time from a single dashboard. This reduces manual intervention and boosts operational speed and customer satisfaction.
With carrier integrations such as Yurtiçi, Aras, MNG, Hepsijet and DHL, we make your shipping processes fully automated. As soon as Shopify orders are handed to the carrier, tracking numbers land in the system instantly. Your customers follow deliveries seamlessly while you save time on logistics.
We enable two-way data flow between ERP systems such as Logo, Mikro, Nebim and Netsis and your Shopify store. Stock, invoice and order information is updated automatically, with no need for manual data entry. Thanks to this integration, your financial processes become more transparent, faster and error-free.
With Omnisend, Klaviyo, Mailchimp and HubSpot integrations, we pull customer data from Shopify automatically. With segmentation, automated email flows and personalized campaigns, we increase customer loyalty. Thanks to CRM integration, your brand's communication stays consistent at every touchpoint.
With Google Analytics 4, Meta Pixel, Google Merchant Center and Looker Studio connections, we gather your marketing data in a single ecosystem. We measure your Shopify store's conversion rates and let you track performance in real time. This way, you can optimize your ad investments based on data.
We can develop custom payment infrastructure solutions for Plus stores. With Shopify Markets integration and multi-currency support, we make your global sales operations seamless. For customers in different countries, automatic pricing, tax and shipping calculations kick in. Your brand scales in international markets with a professional user experience.
Integration ends the practice of entering the same information into two systems by hand. First, the primary source of each piece of data is defined: for most brands, products, stock and prices come from the ERP; orders are created in Shopify and distributed from there to the ERP, the shipping carrier and the accounting software. The flow below summarizes the setup we built in our Nebim, Logo, SAP and Paraşüt projects.
Live examples: Nebim at Antioch and Vamos, Logo at Bonne Nuit, SAP at Volta Motor, and Paraşüt (a Turkish cloud accounting tool) plus eight shipping carriers at our own brand Haters Studio. For a brand without an ERP, Shopify becomes the primary source of products and stock; the shipping and invoicing flow stays the same.
Most sync errors come from two systems changing the same field. That is why, during discovery, each data type gets one primary source, one direction and one trigger. In a Shopify store that uses an ERP, the table typically looks like this:
| Data | Direction | When it is transferred | What we watch for |
|---|---|---|---|
Product record and varianttitle, SKU, barcode | ERP → Shopify | When a new product is created and when the record changes | The matching key is the SKU or barcode, not the product name. Descriptions, images and SEO fields are edited in Shopify; the ERP transfer does not overwrite them. |
Stockby location | ERP → Shopify | On every stock movement; with bulk updates for large catalogs | ERP warehouses are mapped one to one to Shopify locations. Retail store, main warehouse and returns warehouse are defined separately. |
Pricelist and sale price | ERP → Shopify | When the price list changes | For sale prices, the original price goes into Shopify's compare-at price field; the campaign starts and ends in both systems at the same time. |
Order | Shopify → ERP | The moment the order is created, by webhook | An order that cannot be transferred waits in the queue and is retried; the error is logged, and no order is lost silently. |
Billing detailsTurkish ID number, tax number | Shopify → ERP or accounting software | Together with the order | The distinction between individual and corporate invoices is read from the checkout fields; the choice between e-Fatura and e-Arşiv, Türkiye's two e-invoice types, is made accordingly. |
Shipment and tracking number | Shopify → carrier, tracking info carrier → Shopify | When the order is packed; whenever the shipment status changes | Once the tracking number is written to the order, Shopify's shipping notification goes to the customer automatically. |
Invoice | Shopify → Paraşüt or ERP | When the order is fulfilled | No separate accounting entry is needed. At Haters Studio, the invoice is created in Paraşüt automatically when the order is fulfilled. |
Returns and cancellations | Shopify → ERP and accounting | When a return or cancellation is recorded | Partial returns, orders split across two shipments and cancellations after payment are tested as separate scenarios; stock goes back to the location where the return was received. |
For a brand without an ERP, Shopify is the primary source of products, stock and prices; the table then consists of the order, shipping and invoice rows.
Our core strength at Nodus Works is building custom Shopify apps tailored to your store. Using the Admin API, Storefront API, Shopify Functions and webhook infrastructure, we build bespoke solutions for every operational need that off-the-shelf apps cannot meet. Private apps installed only on your store — not listed on the App Store — give you full control over your operations.
Private apps installed only on your store, not published on the App Store. Directly integrated with your ERP, WMS, B2B portal and internal systems.
Custom API connections that sync order, inventory, customer and product data in real time. Bidirectional data flow eliminates manual entry.
Custom discount rules, payment flows and checkout extensions. Advanced customization and multi-market support for Plus stores.
Custom workflows triggered automatically when orders are placed, stock changes or returns arrive. Turn your operations into 24/7 automation.
Custom bridge apps with Logo, Mikro, Nebim, Netsis, SAP, carriers, CRM and marketplace APIs. Seamlessly connect your existing software investment to Shopify.
Ongoing support, security updates and new feature development for live custom apps. Scalable architecture that adapts to your growing operations.
A custom app connects to the store through the Admin API and webhooks; the part you see on screen is added through Shopify's extension points. Because no code is embedded in the theme or the checkout, the app stays in place when the theme changes or is updated.
Features such as stock alerts, size charts or dealer pricing are delivered as app blocks and app embeds that are added and removed in the theme editor on Online Store 2.0 themes.
Fields, notices or offers are added to checkout. Extensions in the information, shipping and payment steps are exclusive to Shopify Plus; thank you and order status page extensions work on all plans.
Discount logic, hiding or reordering shipping options, filtering payment methods, cart validation and bundle rules run on Shopify's own infrastructure. In a store-specific custom app, Functions require Shopify Plus.
The order's ERP transfer status, invoice number or shipping barcode appears on the order screen; actions such as “Resend to ERP” are done inside the admin without switching panels.
Custom pages and blocks are added to the new customer accounts: dealer balance, points status or a donation summary. At Wear the Peace, the donation and impact panel sits inside the customer account.
Technical specs, care instructions or dealer terms coming from the ERP are not pasted into the product description; they are written to defined fields. The theme, filters, mobile app and marketplace feeds all read from the same field.
The app is installed only with the access scopes it needs, and keys are kept in encrypted environment variables, not in the code. Every webhook from Shopify is verified with its HMAC signature; a request with a mismatched signature is not processed.
Incoming events go into a queue first. If the other system is down, the job is not lost and is retried at increasing intervals; the same event arriving twice does not create a duplicate record. A regular reconciliation job picks up missed events.
Each figure comes from the real operations of a single brand, taken from our case studies.
From needs analysis to post-launch support, we plan and manage every step of the integration process for you, end to end.
We review your existing processes: payment, shipping, ERP, CRM. We prepare an integration plan suited to your brand's volume and operational structure.
We determine the applications to be used (Shopify App, custom API, third party). We complete the work needed for the required licenses, permissions and security configurations.
The selected systems are integrated into the Shopify admin. Data matches (product, customer, order ID) are established.
Order, stock, price, customer and shipping scenarios are tested. We make sure all data flows work correctly in both directions.
We show your team how to manage the integrations from the dashboard. Processes such as shipping label printing, invoice syncing and email automations are explained.
After all systems go live, we monitor performance and data for the first 30 days. In case of any issue, we provide instant intervention and correction support.
Off-the-shelf Shopify apps don't meet every business need. Nodus Works builds custom apps from scratch based on your brand's unique operational requirements — from B2B sales to warehouse management, custom invoicing to customer portals.
Customer-specific pricing, minimum order limits, approval flows and dealer portal. Run your wholesale operations fully automated on Shopify.
Multi-warehouse, batch tracking and real-time stock sync. Eliminate stock inconsistencies between marketplaces, ERP and Shopify.
Carrier selection, automatic label printing and tracking number transfer. Custom integration apps for domestic and global carriers.
E-invoice, e-archive and ERP invoice sync. Automate your entire financial process from order to invoice with a custom app.
B2C customer panel, points system and custom campaign management. Deliver a personalized shopping experience to your customers.
Multi-channel sales reports, KPI dashboards and data visualization. Manage all operational data from a single custom app panel.
Station is the central management layer that sits between your Shopify store and marketplaces like Trendyol and Hepsiburada. You enter product, stock and price once; Station distributes this information automatically to all your sales channels. That way you no longer have to update each panel separately and stay consistent and up to date across all your channels.
Define product, description, price and stock in Station once; let them appear the same, accurate and up to date across Shopify and your marketplaces. Your brand consistency is preserved on every channel.
When a sale happens on one channel, stock updates instantly across all channels. The "we sold it but it's out of stock" scenario, along with the cancellations, returns and negative reviews it causes, disappears.
Make a price increase, discount or campaign decision once; Station pushes it to all channels within minutes. With bulk updates you manage hundreds of products at once and handle seasonal transitions effortlessly.
Orders, returns and cancellations from all channels land in Station automatically. You track what you sell on which channel and its real stock impact from one place.
Connect Trendyol, Hepsiburada, N11, Amazon and more to a single Station account. Adding a new channel takes minutes; your product and stock information is carried over to that channel instantly.
See which channel and which product sold how much on a single dashboard. With Station's reports, manage your profit margin, stock turnover rate and channel performance based on data.
Not every need calls for custom code. In the discovery call, we first check whether a ready-made option does the job; we decide on custom development only after the limit of the ready-made option is clearly visible, and together with a maintenance plan.
| Path | Its limit | When it is the right choice |
|---|---|---|
Shopify App Store app | Its logic cannot be changed. Two apps touching the same data conflict, and each requires its own monthly subscription. | When the need is standard and your workflow fits the app's logic: basic shipping, email, product reviews. |
Shopify Flow | Not designed for complex data exchange with external systems or for error recovery. | Recurring rules inside the store: hiding a product when stock hits zero, tagging high-value orders, sending notifications to the team. |
StationNodus Works app | If a brand-specific pricing rule or category mapping is needed, it is used together with custom development. | When marketplaces, the ERP and shipping are to be managed from a single panel with the same stock and prices. |
Store-specific custom app | It needs maintenance. Shopify releases a new API version every three months, and the app is updated on that schedule. | When the ERP has a brand-specific setup, or when a custom screen inside the admin or a business rule with Functions is needed. |
Public appShopify App Store | It goes through Shopify's review; compliance with App Store rules and the Billing API is required. | When the same need exists in many stores and is worth turning into a product. We have more than 15 apps live on the App Store. |
Middlewareintegration layer | Requires a separate server, monitoring and security management. | When several internal systems outside Shopify, such as warehouse, production and legacy platforms, need to meet in one hub. |
We do not recommend a custom app for a need that the first three rows of the table can solve. In the proposal, we state in writing which path we chose and why.
In integration projects, three of our apps most often take the place of custom code: Station brings marketplace, ERP and shipping connections into a single panel, Syncly keeps stock and prices aligned across two or more Shopify stores, and Goldus refreshes prices indexed to gold and exchange rates with the current rate. Because we build and maintain all three ourselves, updates to these connections do not need to be planned separately the way store-specific code does.

Instead of writing a separate connection for every marketplace and shipping carrier, Station becomes the hub. Products, stock and prices are entered once and distributed to marketplaces; ERP transfers and shipments are tracked from the same panel.
View Station
For a brand selling the same product in more than one Shopify store, stock that drops in one store has to drop in the others as well. Syncly aligns stock and prices across stores automatically; prices are calculated with the margin rule you set for each store. There is no need to build separate middleware for two Shopify stores.
View Syncly
For products priced against gold or a currency, changing prices by hand with every rate movement is not feasible. Goldus updates product prices automatically based on the current rate; if prices do not come from the ERP, no separate integration is needed for rate data.
View GoldusWhich data is written by which app or connection is decided during discovery, together with the data direction table; no field is changed by two solutions.
We're ready to integrate your Shopify store with your ERP, shipping, CRM and accounting systems — and build custom apps tailored to your store. Let's discuss your needs in a free meeting.
Book a MeetingThree brands, three different source systems: an enterprise ERP, a retail-focused ERP and an accounting tool. The screens are from the live stores.
Volta Motor runs its operations on SAP. We moved the store from Ideasoft to Shopify and connected it to SAP; when a price or stock level changes, the site updates on its own, and online orders are processed directly in SAP.
We built a custom sync app that connects Antioch's Shopify Plus store to Nebim. Products, stock, prices and orders flow between the two systems without manual transfers; a sold product never stays available on any channel. The same setup was later applied at Vamos.
We test the setups we recommend to clients in our own brand first. At Haters Studio, the invoice is created in Paraşüt automatically when the order is fulfilled; shipments go out through eight carriers from a single flow, without entering data in separate panels.
Shopify shipping integrations fully automate all your post-order fulfillment processes. When an order is created, the system works in sync with the relevant carrier to generate shipping details automatically and adds the tracking number to the order. Customers are notified by email and SMS as the shipping status changes, ensuring transparent communication throughout the delivery process.
When your shipment is delivered, the order is archived automatically and the process is closed. It is compatible with sender-paid and cash-on-delivery shipping types; for cash-on-delivery shipments, the payment amount is deducted automatically from the order total. It works seamlessly with carriers used in Türkiye and globally, such as Yurtiçi, Aras, MNG, Sürat, DHL, UPS, ShipEntegra and ShippyPro. To activate the integration, all you need is to enter the API credentials of the relevant shipping provider.
