Overseas Investment Crowdfunding System / Vietnam Investment Finance / Frontend VUE – Complete Multi-language System Setup Guide

This time I helped an overseas client set up an investment crowdfunding system targeting the Vietnam market. The system needed to support Vietnamese and Simplified Chinese, frontend built with VUE and backend with ThinkPHP. The entire process from domain selection to payment integration took about two weeks. Here I am documenting the core setup steps and pitfalls encountered.

1. Core System Features

This overseas investment crowdfunding system is specifically designed for Vietnam and Southeast Asia markets, using a frontend-backend separated architecture. The frontend supports Vietnamese and Simplified Chinese switching, and backend product information can be customized without project type limitations. Main features include:

1. Multi-language Support: VUE frontend implements Vietnamese and Simplified Chinese switching via i18n plugin, backend unified management of multilingual content
2. Crowdfunding Project Management: Supports creating various types of investment crowdfunding projects including equity investment, debt investment, real estate crowdfunding and more
3. Investment Finance Features: Supports term financial products, demand deposits, direct project investment and other investment modes
4. Admin Management System: Built with ThinkPHP, fully featured, flexible project parameter configuration
5. Complete Member System: Supports real-name authentication, level permissions, commission promotion and more

2. Pre-Setup Preparation

Deploying this system requires attention to these key points:

• Server Selection: Recommended Singapore or Vietnam server nodes for low latency, 2-core 4GB minimum
• Multi-language Configuration: VUE frontend implements multilingual via i18n plugin, prepare Vietnamese and Simplified Chinese language packs in advance
• Payment Gateway Integration: Common Vietnam payment methods include Vnpay, MoMo e-wallet, apply for merchant accounts in advance
• Database Configuration: MySQL 5.7 or higher, utf8mb4 charset for multilingual content storage
• SSL Certificate: Valid SSL certificate required, otherwise payment callbacks cannot communicate properly

⚠️ Important Note: Overseas investment finance systems involve fund transactions. Before deployment, confirm financial regulatory requirements of the target country. Some countries require licenses for legal crowdfunding platform operation.

3. Common Issues and Solutions

3.1 Vietnamese Character Display Garbled

If Vietnamese characters display garbled on frontend, check three places: whether database charset is utf8mb4, whether VUE project meta charset is set correctly, and whether frontend API response Content-Type header includes charset=utf8.

3.2 Payment Callbacks Not Received

Payment callback failures are usually caused by server firewall blocking payment platform callback IPs, or SSL certificate configuration issues. Recommend configuring test environment in payment platform backend first to verify callback address reachability.

3.3 Crowdfunding Project Review Process Configuration

The system supports three-level review mechanism, configurable in backend “System Settings”. Recommend disabling review function initially when first launching, enable after business process runs smoothly.

4. Custom Development and Extension Options

Extensions available based on business needs: integrate more Southeast Asian localized payments (GrabPay, CKYCash), develop mobile APP (Flutter has better multilingual support), add blockchain point system for decentralized asset management.

5. FAQ

Q1: How many languages does the system support?
A1: Current version supports Vietnamese and Simplified Chinese, theoretically extensible to any number of languages by simply adding language packs.

Q2: Can it integrate cryptocurrency payment?
A2: Yes, system has reserved payment interface extension points, can integrate USDT TRC20 or ERC20 wallet collection.

Q3: Can project types be modified in backend?
A3: Yes, backend supports modifying project name, investment amount, return rate and other parameters, but project ID cannot be changed.
