API Development & Systems Integration
We build the APIs and integrations that let your systems work as one: a partner API for your customers, a web shop that talks to the ERP, payments and carriers connected to your orders, or an older application opened up to new tools.
An integration is only finished when it fails safely. Every connection we deliver comes with a clear integration architecture, authentication, documentation, automated tests, retries and monitoring — so an outage at one end never silently loses an order at the other.
- REST and GraphQL APIs for customers, partners and your own apps
- Integrations between ERP, CRM, e-commerce, payment, shipping and accounting systems
- Integration architecture: event-driven messaging, webhooks, queues and API gateways
- Opening up legacy software through a clean, documented API
- Authentication and access control: OAuth 2.0, API keys, scopes and rate limits
- OpenAPI documentation, contract tests, monitoring and alerting

Copy linkOperations ERP for service businesses
End-to-end operations on one platform: client and site management, shift planning and assignments, timesheets and billing — built as custom ERP modules and used daily in production.
- Shift planning across sites and teams
- Timesheet capture and approval workflows
- Automated billing from approved hours
- Mobile PWA for staff in the field
Try it: Check in on the phone and watch the ERP update, then approve Noah's timesheet and send the invoice.

- 01 /
Built for partners
Versioned, documented APIs with a sandbox, so other teams can integrate without waiting for you.
- 02 /
No silent failures
Every message is acknowledged, retried with back-off and parked for review if it still fails — and can be replayed.
- 03 /
Secure by default
Scoped keys and tokens, rate limits, input validation and audit logs on every endpoint.
- 04 /
Observable
Latency, error rates and queue depth on one dashboard, with alerts before your users notice.
- 05 /
Vendor-neutral
We connect what you already run — commercial platforms, open-source tools or your own software.

When a connected provider changes its API, we update the connector before it breaks.

Straight answers about how we work. Can't find yours? Ask us directly.
Can you connect our online shop to our ERP?
Yes. We synchronise orders, customers, stock, prices, payments and shipments between web shops, marketplaces and ERP systems, with retries and a log of every message so nothing is lost.
Do you build APIs that other companies use?
Yes. We design and build versioned REST and GraphQL APIs with authentication, rate limits, OpenAPI documentation and a sandbox, so partners and customers can integrate on their own.
Our software is old. Can it still be integrated?
Usually, yes. We add an API layer in front of legacy applications or databases, so new tools can use them safely without a risky rewrite.
Who maintains the integrations after go-live?
We can. Support agreements cover monitoring, alerts and updates whenever a connected provider changes its API.
