FAQ
Pricing questions.
Something else? Ask us directly.
Why don't you list prices?
Every app and idea is different, so we'd rather quote what you actually need than make you pay for a one-size package. A short call is usually enough for us to give you a fixed quote.
Is the quote fixed?
Yes, for the scope written in your proposal. If something new comes up, we quote it before doing it, never after.
Do I need Orbit?
No. Every project ends with a runbook so you can run it yourself. Orbit is for founders who'd rather spend their time on customers.
How do payments work?
Scan and Map are paid up front. Larger projects are split: half to start, half at launch. Orbit is billed monthly.
Not sure which path fits?
Tell us where you are. We'll recommend the smallest first step, and it's credited if you continue.
