As title, the user is a friend of the original unit, they don't have software personnel, are under a machine, and then I was introduced, to the user use Delphi to develop a set of PC software,
Now don't know what is good and only take charge by set a good development costs, I tend to charge by set, each set can be low, many a mickle makes a muckle (don't know how much they will sell), if only a development fee, where are you going to charge high is not high

CodePudding user response:

Sold by is expected to set how much they can buy, not the number of words can't evaluate ah, look at your idea is to put the software as a product to sell, the scope of sales is not only confined to this unit, the idea is good, but the demand of the market and their own advantages to touch first clear,

CodePudding user response:

Using network authentication, membership, how much money each year, I did

CodePudding user response:

How see you at that time,
If the other party commissioned development that can not be charge by set,
Lump-sum payment had higher prices
According to the set of a single set of price can not too expensive, but you'd better prepare for each other is not in accordance with the rules to the psychological expectations, there must be a verification mechanism on the function,

A friend of cooperation with others, others pushed his software, according to the commission, result pushed the guy again for someone to give cracked his software, ha ha

Tell you responsibly that in China, the pure software, in addition to how much one can calculate how much, in addition to this, what is floating clouds, haha
So I always all is the hardware and software together, even if the hardware is not necessary to have, and each is different, to write a small program with a MCU

CodePudding user response:

If only a development fee, maintenance will not charge?

CodePudding user response:

Or development is cheaper, maintain/update the pay-per-view good ~ ~ ~

This method is good

According to the fixed number of year fee ~ ~
