Customer credit scoring combines financial, legal, commercial and payment behaviour information to support consistent credit decisions. It helps credit managers identify risks, tailor payment terms and protect receivables without unnecessarily restricting sales. Extending trade credit supports business development, but it also exposes suppliers to late payments and bad debts. A structured assessment of a customer's creditworthiness helps balance commercial opportunities with acceptable risk. Credit scoring is a practical way to make this assessment more consistent. It brings together different indicators and produces a rating that can inform decisions on customer credit analysis, credit limits, payment terms and guarantees. The method assigns weights to relevant indicators and combines them into an overall assessment. The original Credit Notation approach considers a range of financial, legal and behavioural factors, including: Financial information can be analysed further through the guides on profit and loss statements, balance sheets and key financial ratios. The Credit Notation method groups customers into four broad risk categories. These categories provide a common language for sales, finance and credit management teams. These descriptions are indicative rather than universal definitions of default probability. A weak score should prompt further investigation, not an automatic conclusion that a company is about to fail. The purpose of scoring is not merely to assign a grade. It is to help determine the most appropriate commercial and financial conditions for each customer. A rating is therefore one input into the overall credit decision, not a substitute for commercial context or expert assessment. Some private companies do not publish detailed financial statements or are reluctant to share them with suppliers. Disclosure practices vary across jurisdictions and businesses. In such cases, a simplified scoring model can draw on available indicators such as payment history, company age, commercial relationship, order trends and relevant external information. However, the absence of financial statements reduces the certainty of the assessment and should be acknowledged explicitly. Credit managers should distinguish between missing information and evidence of financial weakness. These are not the same thing. A more detailed scoring approach combining company profile, financial indicators and payment information. A simplified approach based on nine criteria, useful when less information is available. The tools may require an account to calculate and save results. Review the methodology and configure criteria where available. My DSO Manager integrates credit assessment into broader credit management and accounts receivable processes. Its scoring criteria can be adapted to a company's credit policy and customer portfolio. Combining credit assessment with receivables monitoring, collection activities and dispute management helps teams translate risk information into coordinated action while supporting customer relationships.Customer Credit Scoring: How to Assess Creditworthiness
