02 / Process
How we work
- 01
Requirements
We review the applications involved, how information needs to move between them and any existing integration options.
- 02
Scope & Quote
We review the available APIs, technical requirements and integration options, then provide a project quote and timeline.
- 03
Development & Testing
We build and configure the integration, test data transfers and check error handling and synchronization.
- 04
Delivery & Support
We provide the agreed handover and documentation. Ongoing monitoring, maintenance and improvements can be arranged separately.
Where an existing connector can meet the requirements, we consider it before proposing custom development.

How pricing works
We review the project requirements before confirming the scope and final price. Smaller, clearly defined tasks can be quoted separately from larger implementations. Additional work is discussed and quoted before it begins.
Have a specific budget?
Include it in your inquiry. We can review the requirements and discuss what is achievable within your budget.
Final pricing is confirmed after reviewing the project scope. Software subscriptions, API usage, hosting and other external costs are separate where applicable.
