At handoff, all of it is yours. **Scope and price are agreed before work starts, and we don't bill by the hour.** The same Chicago team handles your project from the first call to the final handoff.

## How we charge

A project gets a fixed scope and a fixed price. An ongoing product gets a set amount of engineering each month. Advisory is a fixed engagement attached to a build.

Fixed-scope project

### A written SOW, one price, one date

Most builds work this way. We agree what gets delivered and when, and you know the price before we write a line of code.

Product partnership

### An ongoing team for evolving products

For software that keeps growing. You get dedicated engineering time every month, and we ship in two-week sprints.

Advisory & architecture

### Strategy before you commit

Shorter work, such as an architecture review or technical due diligence. Some clients want a second opinion before a major investment.

We quote every engagement at a set price **after a free discovery call**, and we don't bill by the hour. At handoff you own **everything**: the code, the infrastructure, the accounts and the domain.

## Live in production

The easiest way to judge an engineering team is to look at what it keeps running. These are live now.

LIVE · 6 CLINICS · 3 STATES

### Quantum Prosthetics & Orthotics

A website for six clinics in three states: clinic pages, patient guides, a consultation form.
