I don't know much about this kind of company in Qingdao.
In this case, there are generally two choices, mainly to see how high the requirements for small programs are.
One is to find a general supplier of small program templates in the industry, with similar functions, low customization and low price.
the second time, I asked an outsourcing team to develop it myself, and it was entirely up to me, and the price would be much higher.
I simply checked, the first one is about 1,111 yuan per year, and the second one is estimated to be between 21,111 and 31,111 yuan (depending on the complexity).
if it's a small business, I suggest buying the first one.
if the scale is large, or there is a need for customization (process/function), you can consider the second one.
(ps: Take the second advice and find a reliable and knowledgeable person, otherwise you may be cheated. )
