I can't resist this one.
If you quote a price and the customer says 'OK' right away you left money on the table. If they take some time and then buy you are probably priced right or maybe low. If you don't get the job and someone else does you may be priced to high and if you don't get the job and no-one else does then you are probably too low since obviously no-one else would do it for less.
Now, are you ripping your customer off? Not a chance. You are providing a valuable service and charging appropriately is what you want to do. If you were to take a Business 101 class the first day of class you will be told to charge the highest price you possibly can. This is not evil or bad, it is just business. It is not immoral or bad to make a profit.
Looking at it from the other side, your customer doesn't come to you each month and ask you how you are doing. They don't directly invest in your equipment, offer to pay part of your rent, utilities, or operating expenses. If you were to go out of business tomorrow they would look for someone else, never giving you another thought.
It is just business, not emotional. Charge the right price and everyone will be happy. If you think it is $3000 and the customer buys, then it is $3000.
Look at some examples:
- Iphone: $600 today. Down the road it will be much less.
- Infiniti: These cars are the same as Nissans, made on the same assembly line with just a few more features but priced $7K-$20K more than the Nissan. Service is more than double also for the Infiniti than the Nissan for the same parts. The difference? A little more attention paid to the customer and 'free' loaner cars.
- WordPerfect: When it came out it was $900. Nearly all software packages for the PC was that price. Borland came out with $99 for a similar product and WordPerfect practically went out of business. Today you can get the product free.
Don't discount the value you add. Your business is almost a commodity but your skill and creativity differentiate your product and the markup needs to be there for that part of your business.
Good luck and don't lower the price if you got the job already.
