I have an upcoming salary adjustment meeting at my current job and want to be well prepared for the meeting - and I definitely sucked at the initial salary negotiation, so I need some help.
I work at a consultancy writing software for many different clients. They bill clients an hourly rate around three times my salary.
How can I convince my manager that I deserve a bigger piece of the pie?
1. Biggest hammer, but the most work: you get a job offer elsewhere for job you are willing to take, at higher pay, and see how it goes.
2. Less work: figure out coworker salaries. Figure out salaries in your geographical region. If you can show you are underpaid you are implicitly saying "look I can go get a job elsewhere for more" without having to do the interviewing.
3. Important—make sure you ask for higher salary _before_ the meeting. By the time the meeting happens they've probably decided on salary.

Is that a thing where you trying to prove your worth to get a raise and your boss is trying to politely convey that you're "more than ok" as is?
Create "salary adjustment meeting" on your terms. Get a [real] offer from another place and put it on your boss desk.
Salary adjustment accomplished.
Unless of course your boss will shake your hand and wish you a good luck.
