Mini-programs and H5
Apps that live inside WeChat, Alipay and Douyin — quick to open, easy to return to.
01Overview
For many businesses the main touchpoint is not the website but WeChat, Alipay and Douyin. Mini-programs suit frequent, logged-in, transactional use such as bookings, ordering, membership cards and shops; official-account H5 pages suit campaigns, forms and shareable content; Douyin mini-programs tie into short-video and live-stream traffic.
Two common mistakes: writing separate code for every platform, which multiplies maintenance, or forcing one codebase everywhere and compromising each. We choose uni-app, Taro or native per project and keep shared business logic on the server.
Launch also requires platform review: service categories must match your business license, some need extra permits, and privacy disclosures must be accurate. We check these before building.
02Who it is for
Stores and local services
Restaurants, salons, gyms and repair services needing bookings, ordering and membership cards via a QR scan.
Companies with an official account
An existing WeChat following that could use forms, campaigns, lookups and services through H5 or a mini-program.
Brands needing multi-platform reach
Users spread across WeChat, Alipay and Douyin, served from one main codebase.
Internal mobile tools
Field work, inspections, approvals and time reporting, more easily distributed as a mini-program than an app.
03Core modules
Login and phone authorization
WeChat and Alipay authorized login and compliant phone-number access, linked to existing members or CRM.
In-app payments
WeChat Pay, Alipay and Douyin Pay for orders, stored value, refunds and split settlement.
Bookings and ordering
Resources by store, staff and slot; queues, check-in verification, delivery and table-QR ordering.
Membership cards and coupons
Digital cards, points, stored value and coupons, synced to the WeChat card wallet and redeemable in store.
Subscription messages
Order, booking and campaign notifications via approved templates, balancing reach against annoyance.
Official-account H5 and JS-SDK
Web authorization and JS-SDK for custom share cards, scanning, location and uploads in campaigns and forms.
Cross-platform build
uni-app or Taro compiling to WeChat, Alipay and Douyin mini-programs and H5, with conditional code per platform.
Admin console
A web console for products, bookings, orders, members, content and reports, with multi-store roles.

07What drives the quote
Every scope differs; we quote once we understand the requirements.
Number of platforms
WeChat only is simplest; adding Alipay, Douyin and H5 means handling differences and separate reviews.
Functional scope
Showcase, booking, shop and multi-store SaaS each step up in complexity.
Existing systems
Integrating POS, membership, ERP or an existing back office adds API work.
Admin complexity
Single-store admin versus multi-store, multi-role permissions differ substantially.
08FAQ
What if the review is rejected?
Usually the category does not match the features, a permit is missing or privacy disclosures are inaccurate. We check these upfront and address review feedback point by point.
Can one codebase cover WeChat, Alipay and Douyin?
uni-app or Taro gives substantial reuse, but login, payments and messaging differ per platform and each needs its own testing and review.
Mini-program or native app?
Mini-programs need no download and spread well through WeChat. Apps suit background, offline or heavy interaction needs. Many companies start with a mini-program.
Who owns the account and code?
The mini-program is registered under your business and belongs to you. Source code is handed over on acceptance and payment.
