How do people here price a project ? Obviously one answer would be the most that a company is prepared to pay for it, however, if you are trying to sell a kit to multiple customers, what will generate the most return and what's fair ?
A successful salesman I know (who is still a decent man) said that the game he played was to guess the price the customers had in mind and go just arginally over that. He could then offer a discount, and everyone was happy with the arrangement. Likewise if you went in too cheap, the customer would be suspicious and probably not order.
Another friend who runs a successful engineer business (not from his garage I should add LOL) said that their prices were 3 times the total cost of manufacture, 1/3 to make the product, a 1/3 went to marketing/sales/support and the last 1/3 was the profit. This didn't account for any development costs that needed to be spread over the entire product's life.
Another approach, which I regard as pretty immoral, is trying to get a customer over a barrel. What I mean is that you have a vague specification (or none) and then do a very basic design. The customer is ususally so desperate to get the product that they don't have time to go elsewhere then pay through the nose for 'modifications'. I find that Microsoft springs to mind here.
Anyway as this forum seems full of decent engineers, let's do a survey... if you could buy, say, an LCD display module from Ebay that did exactly what the customer wanted (assuming that there was no need to do any development for simplicity). You instruct the customer how to use the module (so there is a little support there) and they cost $10 each and they buy them in batches of 100 from you. What would people regard as a fair price to sell them for ? How did you come to that figure ?
