Questions
Before you get in touch
The things most people ask on the first call.
What does a project cost?
Every project gets a written, fixed-price quote before work begins, so you know the total up front. Most engagements are either a fixed-scope project or a monthly retainer sized to your environment. If the budget and the problem do not line up, we say so on the first call.
Who owns the code and the accounts?
You do. Everything we build ships with documentation, tests, and a handover, and the cloud accounts, licenses, and source code are in your name from day one.
Can you work with the vendors and systems we already have?
Yes. Most projects extend or connect the tools you already pay for, and we coordinate directly with your existing IT provider, software vendors, or accountant when a change touches their systems.
What happens after launch?
You can keep us on a monthly retainer for monitoring, patching, backups, and support, or take the documentation and run it yourself. There is no lock-in either way.
How do you handle our data, especially for AI work?
Your data stays in your own cloud tenant and is never used to train models. We sign NDAs before discovery, and our access is scoped, logged, and removed at handover.
