Introduction for Part 1 - Identifying Slow-Paying Customers - The battle against bad debt is a continuous challenge for businesses. How can you spot "slow-paying customers" early and collect payments efficiently?

Strategy 1: Top 10 Warning Signs Your Customer Might Delay Payment. Should take immediate action when signal 4 occurs.

​From thousands of cases RMS handled, delinquent customers often show these common traits:

1. Frequent bank account changes — possibly to hide money flows.  
2. Sudden, frequent management changes — a sign of internal instability.
3. Payment terms stretching longer — from 30 to 60 or even 90 days as they test your patience. 
4. **High-risk alert** Missing MPF contributions — often a precursor to liquidation. 
5. Making small payments to “buy time” — while large sums remain unpaid.  
6. Difficult communication — finance contacts become unreachable or delay responses.  
7. Placing unusually large orders — sometimes to confuse suppliers amid financial troubles.  
8. Negative industry rumors — bad news travels fast, so if you hear it, others likely know too.  
9. Suspicious company addresses — virtual offices or secretarial service locations. 
10. Starting to sell assets — such as vehicles or equipment.

👉​Action tip:
If three or more signs appear, raise your alert level. For four or more — especially missed MPF payments — initiate collection procedures immediately. Don’t wait!
