A robust strategy isn't about a single tool, but about building multiple layers of defense. 
Layer 1: Foundational Internal Controls 
This is the bedrock of your credit protection. These are the proactive policies and procedures you manage internally. 
- A Clear Credit Policy: A well-defined document outlining payment terms, early payment discounts, late payment penalties, and your collections process. 
 
- Thorough Credit Assessment: Before extending credit, conduct due diligence on every new customer, evaluating their credit scores, financial statements, payment history, and market reputation. 
 
- Setting Prudent Credit Limits: Restrict the amount of credit exposure you have with any single customer, especially those deemed higher risk. 
 
Layer 2: Transactional Safeguards 
For specific, high-risk, or unusually large transactions, you might employ transactional tools. 
- Letters of Credit (L/C): A bank guarantee of payment, common in international trade. However, they are expensive, complex, and tie up your buyer's credit line. 
 
- Upfront Deposits or Guarantees: Requiring a partial payment before delivery can reduce your exposure on a single deal. 
 
Layer 3: Comprehensive Portfolio Protection 
This is the ultimate safety net that covers your entire book of business. 
- Trade Credit Insurance (TCI): The premier tool for comprehensive credit protection. TCI is an insurance policy that protects your accounts receivable portfolio against the risk of non-payment from commercial or political risks.
