Everyone has a different hourly rate, or a different way of billing.
Some bill by the hour, the project, the value or the outcome.
I have had in the past where clients compare what their experiences have been with other designers and placed that expectation on me. I am not them.
Tell me if you have heard this: “Oh, the last designer did it for $x, can you match that?”. Unless you really need the job, you can say no. That last designer may have undercharged and regrets it or has passed on it because it had scope creep or a difficult client with unrealistic expectations. You don’t want to start off a relationship feeling undervalued, so set that expectation for both yourself and the client.
How to solve
Knowing your worth as a designer/creative/monkey trainer is an everlasting battle. It’s not meant to be easy, it’s putting a dollar figure on your self worth. That shit is hard. But it does get easier the more you do it, and you realise its about finding the clients that value you for the same worth you place on yourself (plus tax).
*HOT TIP* It can sometimes tempting to discount or lower a price when we are about to send the invoice or quote. STOP! You have no idea what their budget or value they are placing on the relationship, and sometimes pre-emptive discounting can do more harm than good!
