If you sell your time and need to give quotes to customers, you'll often round to the nearest zero. Potential might be more likely to accept your bid if you use an exact price.

Freelancers Union explains why this tip may work:
Let's say you're doing an interior design project for a client. You list out all the services you'll provide in your proposal, and then you give them a project fee: $5,000.
The client balks. Even though you provided a breakdown of how you got to that number, they want a breakdown of your hours or an itemized list of expenses. They try to haggle you down another $500.
What would happen if you quoted them a price of $5,180?
I bet your client would be happier. A specific number has greater meaning because it looks like you calculated your cost exactly. You took the time to break down all the custom component costs, and come up with a number for their needs -- not just the number you normally quote. $5,180 looks like an unrounded number with no padding.
It's quirky for sure, and it's no guarantee you'll get the job. If someone else quotes $5,000, the customer might go with the lowest bid. You can always play it safe and go with a bid of $4,980 instead and still take advantage of the idea.
