From a short brief to a product in use
Brief
You describe the problem, users, current process and constraints. One or two pages are usually enough.
Specification
We turn it into scope, architecture, acceptance criteria, risks and a price. A separate paid phase: $490–$1,500.
Build
Design of key screens, then working versions on a staging server that you review along the way.
Launch and care
Testing, release with a backup and rollback plan, then maintenance from $249 a month.
Three options instead of one number
All three are built on the same assumptions, so the trade-offs are visible.
Essential
The minimum scope the product needs to go live, protecting the core workflow.
Recommended
The production version we advise for your goals and risks.
Scale
Adds hardening, automation, analytics, performance work, new markets or integrations.
Billing: fixed scope after discovery, time and materials, or a dedicated team from $6,500 a month.
Questions before you write to us
How much does a software project cost?
Indicative budgets start at $399 for a landing page, $949 for a business website and $4,900 for a web application MVP. The binding price is fixed after a written technical specification.
What do I need to prepare?
A short description of the problem, the users and the current process. Screenshots, sample documents and spreadsheets help. One or two pages are usually enough to start.
What is not included in the price?
Running costs you pay to providers directly: third-party APIs and AI model usage, licences, app store accounts, hosting, SMS and email volume, and taxes. The specification lists them in advance.
Do you maintain the software after launch?
Yes. Maintenance starts from $249 a month and covers updates, monitoring and an agreed allowance for small improvements.
Do you build plugins for Revit and Tekla?
Yes. We develop Revit add-ins, Tekla extensions, BIM libraries and Revit families. You can send the technical specification with files through the form on the BIM page.
Which languages do you work in?
