Common signs of a weak integration
- orders or invoices are still checked manually
- Shopify and ERP show different states
- it is unclear who owns product or inventory data
- integration failures are discovered only after a customer reports them
Custom integration · Shopify and business systems
Connect Shopify with ERP, CRM and internal systems.
We design integration processes around orders, products, inventory, customers, documents and states so it is clear which system owns what and what happens when something fails.
ERP, CRM, PIM, WMS and APIs
Orders, products, inventory and customers
Monitoring, retry and diagnostics
What the integration should deliver
- data mapping and source-of-truth rules
- safe synchronisation with clear logic
- visible state and error history
- controlled retry instead of silent failure
Scope
Each data object needs an owner first.
- Orders, customers, products, inventory and documents
- Sync direction, identifiers and conflict rules
- Webhook, batch or combined processing
- Diagnostics, failure queue and controlled replay
Scope
When this service fits
- a store with ERP or warehouse software
- B2B sales and custom pricing
- a team with frequent manual exports
- a company with internal APIs or middleware
Delivery approach
Integration process
Map
We map systems, API capabilities, data objects, sync direction and volumes.
Design
We define sources of truth, conflict rules, state model and failure scenarios.
Implement
We prepare middleware, webhooks, batch processes or direct API integration as needed.
Verify
We test real data, configure monitoring and document operations.
Outputs
Typical deliverables
- data map and sources of truth
- integration architecture
- API or middleware implementation
- logging, retry and monitoring
- operations documentation
What is not included
What the integration excludes unless agreed
- Undocumented third-party workflows that cannot be reproduced or tested.
- Licences, API limits and availability of the external system.
- Historical data migration or reporting outside confirmed flows.

View details FAQ
Specific answers before the first conversation.
Is direct integration or middleware better?
It depends on the number of systems, data volume, retry logic and ownership. A simple connection can be direct, while more complex processes often need a dedicated integration layer.
Can you connect any ERP or CRM?
It depends on the API capabilities, access, documentation and usage rules of the specific system. We perform a technical assessment before confirming scope.
What is the biggest integration risk?
Unclear source of truth and missing diagnostics. Without them, duplicates, conflicting states and late-discovered failures appear.
