Ask What do you do when the project turns out to be much more work than you originally quoted for?

[Edward22]

At the start of a project, it can be hard to know how much work will be needed, especially when the details are not fully clear. Sometimes the job grows bigger after you have already agreed on a price, and it can feel unfair to continue at the same rate. At the same time, asking for more money later can be uncomfortable. How do you handle this kind of situation without causing tension with the client?
