Mini programs are common enough now that most merchants already have one, and a good number of them are getting real results from it. That is why everyone else is planning one. Development, though, takes a team with distinct roles working together, so companies without in-house developers tend to outsource — which puts the choice of partner at the centre of the whole project.
There are a great many development companies in Shenzhen. How do you tell them apart? In practice the evaluation comes down to six things.
1. Whether the company is properly registered
Check the business licence, the registered name, the address and how long it has been trading. A supplier that will not put the contract, the invoice and the bank account in the same name is not a supplier you want holding your project.
2. Whether it actually specialises in this
“Also does websites and apps” is not the same as “does mini programs”. Ask how many mini programs the team shipped in the last twelve months, and ask what they do when a review submission is rejected — that answer separates people who have shipped from people who have read about it.
3. The level of the technical team
Ask who will actually write the code: in-house staff, or subcontractors. Ask to meet the person who will lead the work. Front end, back end and design are three different skills, and a team of two generalists will produce a visibly different result from a team that has all three.
4. Real, verifiable cases
Ask for mini programs you can open and use, not screenshots. Then open them on your own phone and see whether they still work. A demo that has quietly been abandoned tells you more about the supplier than any portfolio page.
5. Whether the quote is reasonable
A price far below everyone else is not a discount, it is a scope change waiting to happen. Ask what the figure includes, what it does not, and how change requests are priced once the build is under way.
6. What after-sales actually covers
Ask about the warranty period, the response time, whether bug fixes are included or billed, and who owns the source code at handover. Then get it in writing.
Those six will sort most of the field, and the answers are worth more than the quote.
If you would rather skip the shortlist, XZS Tech is a Shenzhen development company with an in-house engineering team, five years of accumulated work and more than 400 custom projects delivered. We build mini programs, official accounts, PC sites and apps on one stack so the channels stay consistent, and we price by module and by phase — published in advance, with no hidden line items appearing after the contract is signed.
