This depends on the choice of small program development methods and functions, such as customized development, but the development price is high, ranging from tens of thousands to hundreds of thousands, mainly because the development cycle is long and it takes months or even longer to put into operation; The other is the third-party platform development, which is low in price and can be well developed according to thousands of functions. The key is that the development cycle is short and it can be put into operation in a week or so.

As for how to choose a development company, you can refer to the following aspects (supplement):

1. See if the company has official website. If an internet company doesn't even have a website, it is conceivable that the possibility of a leather bag company will be even greater.

2. Do Baidu search developers have any negative news? If Baidu search directly appears keywords such as liar, cheating and other related words or negative news in the search results, then the company will choose carefully.

3. Inquire about the company's industry reputation and find some companies that have cooperated with the company to inquire about the situation. Generally speaking, this evaluation is solid, and it is difficult to discard the false and retain the true.

4. Look at its case. If a company doesn't even have a case of software development, it is either a newly established company or a company that has just started to do this business. Either way, it shows that the company has insufficient project experience and its strength is difficult to evaluate. If it cooperates, it is probably a guinea pig.

5. Look at its quotation. The development of small programs determines the duration and price according to the demand function. If the developer doesn't know your required functions, or even what kind of applet you want to make, it's not reliable to quote you as soon as it comes up.
