make a clear service catalog with price.

before you begin a project look a good look at him.

at each customer show exacly what you will charge him and i mean everything -but don't charge your mistake. if you had done 5 days because you didn't know something that require 5 minute you got to charge 5 min

its a good idea this catalog to be used as a contract.

respect the deadline.
if your customers decide that need a new feature
1) charge him for the time that will be lost
2) for the time the new thing will be reguire

Tip 4
Your customer's deadline is not your deadline, his failure to plan is not your problem. Don't let him make you feel under pressure or obliged to prioritise his project unless he is offering a significant extra payment to compensate you.

Note on tip 2: "but don't charge your mistake" - I disagree entirely - the client hired you, not a 100% perfect, all-knowing developer. However long it takes you, it is all entirely billable time. Your mistakes are part of programming, and are not a reflection on your inability.

after 3 tries go away.

if you had make a sketch or a small project and the customer reject it again and again and again, perhaps is time to invest your time to find an other customer.

DON'T try to kill him, that will make you look bad in relationships

be nice with him, -in logical way. don't be rude don't scream don't download his site.

if a problem comes out at the meeting, smile or not try to solve it. if not go out pround, after you had prove that you are wright,
then send him a warning eamil, then other one (3 in a week is my time) and then download their site.

you loose a lost deal but you keep your good name (if you got wright)

don't forget the ghost project.

thats how i name the projects that is running for a long time but without ending. the most regular case is: you give the customer a design or a part of the site, then he encourage a problem and must call you in some time. but the time is endless so both part forget it.

on day somebody call you and tells you that he is the new designer and he wants to handle the domain and he need the DNS.

just call him sometimes to mention anything, just to remind something.

It can pay to be proactive. Guide your customer through the often confusing development process.

Not everyone is tech-savvy. If they are willing, teach them a little bit along the way. The more that they are able to gain from you, the more respect there will be. This respect, in my experiences, translates into referrals and repeat business. They may even put you on speed dial.
