Manual order and stock handling
Staff export orders and import stock levels every day, and overselling happens between updates.

Shopify app integration services that keep your store and back office in sync
We pick the right apps, configure them properly, and build custom integrations when off-the-shelf connectors can't handle how your products, stock and orders really flow.
What is Shopify App Integration?
Shopify app integration services cover selecting, configuring and connecting the apps and external systems a Shopify store depends on. That includes evaluating apps from the Shopify App Store, setting up connectors to ERP, accounting or warehouse software, and building custom apps that use Shopify's APIs and webhooks when no existing app fits. The goal is that products, inventory, orders, customers and payments move between systems accurately without manual re-entry.
Most Shopify stores outgrow manual exports within months: orders copied into the ERP, stock adjusted by hand, invoices re-created in accounting. Connector apps help, but they impose their own data mappings and can fail quietly when a product has an unexpected variant or a webhook is missed. Integration is a data design problem first and a software choice second.
Where Shopify integrations break down
Too many overlapping apps
Several apps touch the same data (inventory, pricing, customer tags) and overwrite each other.
Connectors that don't fit
Off-the-shelf connectors can't map your bundles, warehouses, tax rules or customer-specific prices.
Silent sync failures
When a sync breaks, there are no alerts or logs, so problems surface as customer complaints.
Our Shopify App Integration service
Integration & app audit
We map every system that touches the store, which data each one owns, and which apps overlap or can be removed.
App selection & configuration
Shortlisting apps by data access, maintenance history, performance impact and cost, then configuring them to fit your workflow.
ERP & Odoo integration
Products, variants, prices, stock per location, orders, refunds and customers synchronized between Shopify and Odoo or another ERP.
Custom Shopify apps
Private apps for a single store built on the GraphQL Admin API, with webhooks for real-time events and scoped access tokens.
Shopify Functions & extensions
Custom discount, shipping or payment logic and admin or checkout UI extensions where your plan and Shopify's rules allow them.
Monitoring & error handling
Sync logs, retry queues, rate-limit handling and alerts so failures are visible and recoverable.

What Shopify App Integration changes for your business
No re-typing orders
Orders, refunds and customers flow into back-office systems automatically.
Accurate stock online
Inventory levels update from the system of record, reducing oversells.
Clear data ownership
Every field has one source of truth, so systems stop overwriting each other.
Failures you can see
Logs and alerts usually surface problems before customers do.
Where it makes the biggest difference
Shopify + Odoo for operations
Shopify as the storefront, Odoo for inventory, purchasing, invoicing and accounting, with stock and orders flowing automatically.
Multi-warehouse fulfilment
Inventory per location synced from a warehouse system, with orders routed to the right fulfilment partner.
B2B and wholesale data
Customer-specific catalogues, price lists and payment terms pushed from the ERP to Shopify.
Reducing app costs
Replacing several overlapping paid apps with fewer, well-configured ones or one small custom app.
From system map to monitored sync
We decide which system owns each piece of data before choosing any app or writing any code.
Map systems
List every system, the data it owns, and the direction each data flow should run.
Choose the approach
Existing app, connector, middleware or custom app, decided per data flow.
Design the mapping
Fields, identifiers, units, taxes and edge cases such as bundles and partial refunds agreed in writing.
Build & configure
Apps configured or custom integration developed against a development store.
Test with real data
Sample orders, returns, stock changes and failure scenarios run end to end.
Go live
Initial data sync, switchover and close monitoring of the first days.
Support
Ongoing monitoring and updates as Shopify API versions change.

| Criterion | App Store app | Connector / middleware | Custom app |
|---|---|---|---|
| Setup effort | Low | Medium | Higher |
| Fit to your data | As designed by the vendor | Configurable within limits | Built for your mapping |
| Ongoing cost | Monthly app fee | Subscription plus configuration | Hosting and maintenance |
| Best fit | Common needs like reviews or email | Standard ERP or accounting sync | Unusual data, high volume or strict rules |
Security, quality and scale
Least-privilege API scopes
Apps and custom integrations request only the access scopes they need.
Verified webhooks
Incoming webhooks are verified with Shopify's HMAC signature before processing.
Protected credentials
Access tokens stored in secret managers or environment variables, never in themes or repositories.
Rate limits and volume
Queues and bulk operations respect Shopify's API rate limits during large syncs and busy sales periods.
What working with us looks like
Both sides of the integration
We build Shopify stores and implement Odoo, so we understand the data on each end.
Approach per data flow
We don't force one connector onto every flow; some are best handled by an app, others by custom code.
Built to be monitored
Logging and alerting are part of every integration we deliver.
Kept current
With ongoing support, we track Shopify API version changes and update integrations before older versions are retired.
What it costs
Fixed-price packages with the scope written down, paid stage by stage. Your project goes live once it's fully paid.

Shopify App Integration: questions we hear most
Can Shopify integrate with Odoo?
Yes. Shopify and Odoo can be integrated so products, stock, orders, customers and payments sync between them. This can be done with an existing connector module or a custom integration using Shopify's Admin API and Odoo's external API, depending on how complex your data is.
Should we use an existing app or build a custom one?
Use an existing app when it covers your requirement without workarounds and is actively maintained. A custom Shopify app is worth it when your data mapping is unusual, volumes are high, or you're paying for several apps to approximate one workflow.
What is a custom app in Shopify?
A custom app is an app built for a single store rather than listed on the Shopify App Store. It uses Shopify's APIs and webhooks with access scoped to that store, and is typically used for private integrations and store-specific automation.
Can you customize the checkout through an app?
Partly, depending on your plan. Shopify Functions and checkout UI extensions allow some discount, shipping, payment and checkout UI customizations, and the most extensive checkout customization options are reserved for Shopify Plus. We confirm what's possible on your plan before recommending an approach.
What happens when a sync fails?
In integrations we build, failed operations are logged, retried automatically where safe, and reported through alerts. Your team can see what failed and why, and the issue can be corrected without re-running everything.
