Also if I agreed to a fee of £7k and tried to charge a client £46k without agreeing a new scope of work with a new signed appointment contract I would probably be struck off and fined £20k by my professional regulator.
Haha, software development doesn’t have licensing. I got downvoted for suggesting it should, so it’s unlikely to have it in the future either, unless it becomes government regulated. Which would be its own disaster, and why I think industry licensing should be a thing.
