How we work

From first call to launch — here's how it works

A free consultation starts it. Fixed milestones, weekly demos, and plain-English updates carry it through.

  1. Discover

    A free consultation and a short discovery pass: your goals, your workflow, and what the software actually needs to do.

  2. Design

    A written scope, honest estimate, and clickable designs — so you see the product and the price before we build.

  3. Build

    Senior engineers build in fixed milestones with weekly demos. You watch progress, not a black box.

  4. Launch & Support

    We deploy, monitor, and stay accountable after go-live with maintenance plans and same-team support.

Where is Larkwell Systems located?

Larkwell Systems LLC is a New Mexico limited liability company registered in Albuquerque, serving clients across the United States. We work with businesses nationwide and provide support during US business hours, Monday through Friday, 9am–6pm Mountain Time.

How much does a typical project cost?

It depends on scope. As typical US-market ranges: simple web applications often land between $15,000 and $40,000, larger portals and platforms $40,000 to $100,000 or more, and mobile apps $30,000 to $120,000. Every project starts with a free consultation and a written estimate — no obligation.

How long does development take?

Most MVPs and mid-size builds take 8–16 weeks from kickoff to launch. Larger platforms run longer, and we break them into fixed milestones with weekly demos, so you always know exactly where things stand.

Who actually builds my software?

Senior engineers on our own team — we never broker projects out. Larkwell is a US-registered company with a senior global engineering team; that model is how we deliver senior talent at rates that make sense for small and mid-size businesses. You get one accountable point of contact, available during US business hours, throughout.

What happens after launch?

We stay. Every build includes a warranty period, and our maintenance and support plans cover monitoring, updates, security patches, and improvements — handled by the same team that built your product.
