FAQ
When do we get a formal estimate?
After we decide the scope together. If you order the requirements stage, the estimate is part of what you receive.
What if the scope grows along the way?
We talk with you before it grows and give you an added estimate. We do not start work outside the scope until you agree.
How do monthly fees work?
You pay month by month. The typical term is shown for each item (such as “From 3 months” or “Standard term: 6 months”). We agree on how long to continue together before the contract.
Can we just ask for advice?
Yes, a consultation alone is fine.
Even without settled requirements, let's talk first.
- Our founder replies personally within one business day
- It is fine if your requirements are not settled
- We quote cost after we agree on what to build
- For project requests, you can also pick a 30-minute call after sending
