Smart Settlement Mechanism - Optimized Transactions

After each group activity, balancing settlements is often very complex. Who owes whom how much? How to transfer money efficiently? ChiaHoaDon solves this problem with smart Settlement algorithm - optimizing the number of transactions while ensuring perfect balance.

What is Settlement Algorithm?

Settlement Algorithm is an automated calculation system that finds the most optimal payment method to:

Minimize the number of money transfers
Ensure everyone balances their accounts
Save time and transaction fees

Basic Illustration Example

Situation: 4 people after activity

Minh: Surplus 300,000 VND
Lan: Deficit 100,000 VND
Tuan: Deficit 150,000 VND
Hoa: Deficit 50,000 VND

Manual method (not optimized):

Minh → Lan: 100,000 VND
Minh → Tuan: 150,000 VND
Minh → Hoa: 50,000 VND Total: 3 transactions

Settlement Algorithm method:

Minh → Lan: 100,000 VND
Minh → Tuan: 150,000 VND
Minh → Hoa: 50,000 VND Total: 3 transactions (already optimal in this case)

Why Settlement Algorithm is Needed?

1. Complex Real-world Problems

More Complex Example

Group of 6 people after trip:

Minh: Surplus 500,000 VND (paid more for group)
Lan: Surplus 200,000 VND
Tuan: Deficit 300,000 VND
Hoa: Deficit 150,000 VND
Nam: Deficit 100,000 VND
Mai: Deficit 150,000 VND

Traditional method (not optimized):

Tuan → Minh: 300,000 VND
Hoa → Minh: 150,000 VND
Nam → Minh: 50,000 VND
Nam → Lan: 50,000 VND
Mai → Lan: 150,000 VND Total: 5 transactions

Settlement Algorithm method:

Tuan → Minh: 300,000 VND
Hoa → Lan: 150,000 VND
Nam → Lan: 50,000 VND (Lan now balanced)
Mai → Minh: 150,000 VND Total: 4 transactions (20% savings)

2. Benefits of Settlement

Cost Savings

Financial benefits: 💰 Reduce transfer fees (each transaction ~3,000-5,000 VND) ⏱️ Save execution time 📱 Fewer operations on banking apps 🔄 Reduce transaction error risks

Experience Optimization

UX improvements: ✅ Fewer people need to transfer money ✅ Fewer people receive multiple small amounts ✅ Simple, clear process ✅ Quick completion

How Settlement Algorithm Works?

1. Data Collection

Input data: 📊 Member list 💰 Amount each person spent 💳 Amount each person needs to pay 🧮 Calculate balance (surplus/deficit)

2. Member Classification

Categorization: 🟢 Creditors (People with surplus): Minh (+500K), Lan (+200K) 🔴 Debtors (People with deficit): Tuan (-300K), Hoa (-150K), Nam (-100K), Mai (-150K) ⚖️ Balanced: None

3. Optimization Algorithm

Greedy Algorithm Approach

Process:

Sort Creditors in descending order
Sort Debtors in ascending order
Optimal pairing:

Person with most surplus with person with least deficit
Transfer amount = min(surplus, deficit)
Update balances and repeat

Real Application

Step 1: Minh (+500K) vs Nam (-100K) → Minh transfers 100K to Nam → Minh remaining: +400K, Nam: balanced

Step 2: Minh (+400K) vs Hoa (-150K) → Minh transfers 150K to Hoa → Minh remaining: +250K, Hoa: balanced

Step 3: Minh (+250K) vs Mai (-150K) → Minh transfers 150K to Mai → Minh remaining: +100K, Mai: balanced

Step 4: Minh (+100K) vs Tuan (-300K) → Minh transfers 100K to Tuan → Minh: balanced, Tuan remaining: -200K

Step 5: Lan (+200K) vs Tuan (-200K) → Lan transfers 200K to Tuan → Lan: balanced, Tuan: balanced

4. Optimal Result

Final transaction list:

Minh → Nam: 100,000 VND
Minh → Hoa: 150,000 VND
Minh → Mai: 150,000 VND
Minh → Tuan: 100,000 VND
Lan → Tuan: 200,000 VND

Total: 5 transactions (already optimal for this case)

Advanced Settlement Features

1. Multi-Currency Support

Multi-Currency Processing

Situation: International travel

Expenses in: USD, VND, EUR
Exchange rates: Real-time updates
Settlement: Automatic conversion

Example:

Minh spent: 100 USD + 500,000 VND
Lan spent: 50 EUR + 200,000 VND → AI calculates exchange rates and optimal settlement

2. Preference-Based Settlement

Personal Preferences

Personal options: 💳 Preferred methods: Banking, MoMo, ZaloPay 💰 Transaction limits: Min 50K, Max 5M ⏰ Convenient times: 8AM-10PM 🏦 Preferred banks: VCB, TCB, MB

Smart Matching

Algorithm considers:

Who has same bank (save fees)
Who's online at same time
Who has good transaction history
Who's nearby (for cash transfers)

3. Group Fund Integration

Group Fund Integration

Scenario with fund:

Group fund remaining: 300,000 VND
Person A deficit: 200,000 VND
Person B deficit: 100,000 VND

Smart settlement: → Refund from fund instead of personal transfers → Reduce from 2 transactions to 0 transactions
