Fixed-price project
A written scope split into milestones, each with a fixed price and deliverable. Best when requirements are clear.
Every project is scoped in writing after a free discovery call, so you know the cost of each milestone before any work starts.

It depends on scope, so we start with a free discovery call or a written brief and send a clear estimate broken into milestones. Each milestone has a fixed price and a defined deliverable, so you always know what you are paying for before work begins.
A focused website takes about 7 to 10 days, a larger custom build 15 to 20 days, and a full platform 25 to 40 days, delivered in milestones. We agree the timeline with you before any work starts and show working progress every week.
Yes. We offer 24-hour coverage, and our developers work in your business hours, with regular overlap for the USA, Canada, the UK and Europe, the Middle East, Southeast Asia and Australia. Calls, demos and updates are scheduled in your time zone.
Of course. Most projects begin with a short discovery call to understand your goals, users and constraints. Throughout the project we hold demos and planning calls whenever you need them.
Very likely. We have delivered more than 300 products, live today on the App Store, Google Play and the web, across web platforms, mobile apps, AI products, e-commerce and business software. Share your idea and we will point you to the most relevant work from our portfolio.
Yes, this is one of our most requested services. We audit the existing code, fix what is broken, harden security and deploy it properly, so your prototype becomes a product you can launch. If a rebuild is the better choice, we will tell you why before any work starts.
All three. We take on fixed-price projects split into milestones, hourly work for evolving scope, and dedicated developers or teams on monthly contracts. Many clients start with a project and move to a dedicated team or maintenance plan after launch.
Projects are split into milestones. You accept the offer for a milestone and we get started, and each later milestone works the same way, so you only commit to one stage at a time.
You do. The code lives in your own repository, and all intellectual property is yours once each milestone is paid. We are happy to sign an IP assignment agreement.
Yes. We regularly sign NDAs before reviewing confidential documents or code, and we keep client work private unless you tell us otherwise.
Small adjustments within a milestone are part of the work. When something new comes up, we write down what changes, the effect on cost and timeline, and only proceed once you approve it.
Yes. We set up hosting on AWS, Vercel, Supabase, Firebase or your own servers, and we publish mobile apps to the App Store and Google Play under your own developer accounts, so you keep full control.
Yes. We build for 99.9% uptime and stay on after launch with 24/7 monitoring, bug fixes, updates and new features, either as needed or through an ongoing maintenance plan.
