Unified Backend APIs

Single REST/GraphQL service powering all platform targets.

Desktop Executables

Electron/Tauri integration for Windows and macOS desktop apps.

Deliverables

What you receive

One codebase for both platforms, so features are built and maintained once
Shared business logic and a single API across both platforms
Consistent Visual Identity Across Desktop, Mobile & Web
Rapid Deployment of Feature Updates

Scope, Cost & Ownership

What drives the number on your quote

Cost factors

Number of distinct user roles and the permission rules between them
Third-party systems to integrate, and how well documented their APIs are
Whether existing data has to be migrated, and what condition it is in
Depth of custom design versus adapting an established design system
Compliance or audit requirements that change how we build and test

We quote after a scoping call, itemised by module, so you can see what each part costs and drop anything you do not need.

Typical timeline

Timelines follow scope, so we give you one at the end of discovery rather than before it. What we can commit to up front is the shape of the schedule:

Discovery and a written scope before any build work starts
Working software demonstrated on a fixed sprint cadence, not just at the end
A dated delivery plan you approve before we commit to it

What you own

Full copyright in the source code we write for you, assigned on final payment
The repository, its history, and the deployment configuration
Database schemas, migrations and technical documentation
Accounts and infrastructure registered in your name, not ours

Third-party libraries keep their own open-source licences, and any commercial component is listed in the quote before you sign.
