Whether the company has a mature APP development case: whether the company has a self-developed project case can largely reflect the company's development strength. It is best to combine your own APP development types and let developers send APP cases that are similar to your functional requirements, rather than APP cases in the same industry. Function is the fundamental skeleton, and industry is the skin. A little plastic surgery can make the skin look brand-new, but the pain of bone cutting is beyond the average person's endurance.

Company's APP technology development strength: To find a company with its own technology development team, it is best to make a specific investigation to the company to see the team size of the company. If the company A you are looking for doesn't have its own development team, A will outsource it to B or C, so you don't know whether the development ability of B/C company is reliable. In this way, you are equivalent to finding a leather bag company, which will appear to a large extent during the development of the APP system: before development,

Insufficient communication of requirements, unable to control the development cycle and later development.

There will be no technicians to solve problems such as bugs in APP operation. APP source code development and how to choose a template APP: This needs to be based on your operational needs. The advantage of templates is relatively cheap, but the functional modules are fixed and cannot be changed according to your needs. Secondly, you can't get the source code of the template APP. If there is a bug in the later stage, it can't be changed. Looking for a technical team can't change it. A clever woman can't cook without rice, let alone want to carry out secondary development in the future. Don't even think about it Relatively speaking, the disadvantage of APP source code development is high cost, which generally starts from 15w on the market. Some netizens said don't do anything below 20w, while Bian Xiao said that the specific cost depends on the specific functional requirements. But the source code development is targeted according to your functional requirements, and the UI is also designed according to your aesthetic requirements. After delivery, you can get the development code source. If you want to carry out secondary development in the future, you can take this code source to any development company for secondary development. The cycle of source code development is generally 3-4 months or even longer. The details should be negotiable.

Whether your project can get the attention of the development company. The principle is to give big projects to big companies and small and medium-sized projects to small companies. If you want to develop a 20w project and find a company that is soft on all kinds of 50w projects year after year, you can imagine how much attention the company will pay.

4.

Does your budget roughly match the company's quotation? Generally, if you ask a development company, the company will give you a preliminary quotation first, and then communicate face to face if appropriate. Functional requirements are clear and definite, and the quotation will be adjusted.

5.

Whether to find a company through the platform: this is a matter of opinion. If it can bring you a little psychological security, then make a deal from the platform. The general platform needs to charge a service fee. In fact, to be honest, if there is a dispute in the process of cooperation, everyone will follow the signed contract, whether it is traded through the platform or not. The key is the contract! Say the important things three times.

6.

Does it include a maintenance period? When cooperating with a development company, you must sign a contract, and the terms of the contract must clearly state your functional requirements. The more detailed the better, in case the development company uses vague functional requirements to express your needs as an adult and develop a baby as a result. Be sure to pay attention to whether the contract includes the system maintenance period. During the system maintenance, if there is a technical bug in the operation of the APP, the development company has the obligation to correct it without extra charge. Some developers who refuse to sign this service actually deny their development ability from another angle. After the delivery of the APP and the operation in the market, technical bugs emerge one after another. You have to pay someone to fix the bug, and one end will be a bag.

7.

Word of mouth and disputes: don't trust the customer word of mouth of APP developers too much. APP development is not like going to a restaurant to eat. This is a long period and complicated procedure. The word-of-mouth of others can be used for reference, but don't believe it too much. After all, not everyone is real enough and professional enough. However, disputes do need to be taken seriously, especially for companies that violate contracts. It's best to avoid this. If you can't deliver the APP products according to the delivery time, it will affect your actual operating income.

8.

On-the-spot investigation: You'd better visit the company before the development to confirm several working procedures in the development process. It is much more convenient to communicate. Only when you go to the company can you know the strength of the company.
