Pricing: what a website costs and what is included
Why a fixed price instead of hourly billing?
In short and in plain language
You do not send your customers an open-ended bill either. So you pay us a fixed price.
The price is in the quote before we start. It only changes if you change the scope.
This makes your decision easier.
Answer
Because you do not hand your own customers an open-ended invoice either. The price is in the quote before the project starts and only changes if you change the scope. That makes the decision easier inside the firm and spares both sides the recalculating.
