Definition: Bank guarantee/surety in procurement
Bank guarantees and sureties serve as security instruments for hedging contractual risks between buyers and suppliers.
Basic distinction
A bank guarantee is an abstract, irrevocable promise of payment by the bank to the beneficiary. The bank pays when a claim is made, regardless of the underlying transaction. A surety, on the other hand, is accessory and requires an existing principal debt.
- Bank guarantee: abstract obligation, fast payout
- Guarantee: Dependent on the main contract, defenses possible
- International transactions: mostly bank guarantees according to ICC rules
Bank guarantee vs. other securities
Compared to advance payments or down payments, guarantees offer more flexible security structures. Unlike factoring, the customer relationship remains unaffected.
Importance in Procurement
Guarantees enable buyers to work with new suppliers while minimizing risk. They support international procurement strategies and improve liquidity planning through predictable security costs.
Methods and procedures
The successful implementation of guarantees requires structured processes and clear evaluation criteria for different forms of guarantee.
Guarantee types and areas of application
Different types of guarantee are used depending on the procurement situation. Advance payment guarantees cover advance payments made, while warranty guarantees cover liability for defects.
- Bid bonds: 1-5% of the order amount
- Advance payment guarantees: amount of the advance payment
- Contract performance bonds: 5-10% of the order value
- Warranty guarantees: 3-5% for warranty period
Evaluation and selection
The supplier evaluation must take warranty capability into account. Creditworthiness, bank details and previous guarantee experience all play a part in the decision. Suppliers' credit limits influence available guarantee volumes.
Process integration
Warranties must be integrated into existing procurement processes. This includes contract design, approval processes and monitoring of warranty periods until proper return.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Important KPIs for bank guarantee/guarantee
Effective warranty management requires continuous monitoring of relevant key figures to optimize costs and risks.
Cost efficiency key figures
The warranty cost ratio (warranty costs/purchasing volume) shows the efficiency of the use of warranties. Average warranty costs per supplier enable benchmarking and negotiation optimization.
- Garantiekostenquote: < 0,5% des Einkaufsvolumens
- Durchschnittliche Bearbeitungszeit: < 5 Werktage
- Inanspruchnahmequote: < 2% aller Garantien
Risk management metrics
The utilization rate measures the frequency of warranty calls and indicates supplier quality. Warranty term compliance shows the process quality of warranty returns. These key figures support the optimization of payment plans.
Liquidity and cash flow indicators
Guarantee volume in relation to total assets shows the burden on corporate financing. The correlation between the use of guarantees and cash discounts optimizes working capital management.
Risks, dependencies and countermeasures
Guarantees entail specific risks that can be minimized through professional management and suitable countermeasures.
Operational risks
Unauthorized claims by beneficiaries represent the greatest risk. Unclear warranty conditions or missing documentation can lead to disputes. Exceeding the term causes unnecessary costs.
- Precise guarantee texts with clear conditions
- Regular monitoring of warranty periods
- Documentation of all guarantee-relevant events
Financial dependencies
Guarantees encumber suppliers' credit lines and can restrict their financing scope. In the event of supplier default, there is a risk of loss of guarantee. Netting agreements can reduce risks.
Legal risks
Different legal systems for international guarantees create uncertainties. Currency risks with foreign currency-denominated guarantees require exchange rate hedging. Countermeasures include uniform guarantee standards and professional legal advice.

Practical example
A mechanical engineering company orders a special machine for 500,000 euros with a 30% down payment. The supplier provides a down payment guarantee of 150,000 euros from his bank. The guarantee costs amount to 1.2% p.a. for a term of 12 months. In the event of delivery failure, the company can reclaim the down payment in full. After successful delivery and acceptance, the guarantee is replaced by a warranty guarantee of EUR 25,000 for 24 months.
- Risk minimization for large orders through staggered guarantees
- Plannable security costs of 1,800 euros for down payment protection
- Seamless transition between different warranty types
Current developments and effects
Digitalization and new technologies are changing traditional warranty processes and creating innovative security solutions for modern procurement.
Digital warranty platforms
Online platforms automate warranty processes from application to processing. AI-supported systems assess risks in real time and optimize warranty conditions. This reduces processing times from weeks to days.
- Automated risk assessment through AI algorithms
- Blockchain-based warranty documentation
- Integration into ERP systems for seamless processing
ESG-compliant guarantee structures
Sustainability criteria influence guarantee conditions. Suppliers with better ESG ratings receive more favorable conditions, while supply chain finance programs promote sustainable procurement.
Regulatory developments
New banking regulations influence guarantee costs and availability. Basel IV regulations increase capital requirements, which has an impact on pricing. Alternative forms of financing such as reverse factoring are gaining in importance.
Conclusion
Bank guarantees and sureties are indispensable instruments for risk-conscious procurement management. They enable cooperation with new suppliers with controlled risks and support international procurement strategies. Digitalization optimizes processes and reduces costs, while regulatory developments create new challenges. Professional warranty management with clear KPIs and structured processes maximizes the benefits of these important security instruments.
FAQ
What is the difference between a bank guarantee and a surety?
A bank guarantee is an abstract promise of payment by the bank that is fulfilled independently of the underlying transaction. A surety, on the other hand, is accessory and requires an existing principal debt. Bank guarantees offer faster payment, while sureties allow defenses against the principal debt.
What are the typical warranty costs?
Guarantee costs vary between 0.5% and 2% of the guarantee amount per year, depending on the risk assessment. Factors such as supplier creditworthiness, guarantee type and term influence the pricing. Volume discounts and long-term banking relationships can reduce costs.
When should guarantees be used in Procurement ?
Guarantees are recommended for high order values, new suppliers, international business or critical procurement objects. Guarantees offer important risk minimization, especially for advance payments of more than 20% of the order value or for delivery times of more than six months.
How are guarantees properly processed?
Successful warranty processing requires precise documentation, timely return after contract fulfillment and continuous monitoring of terms. Automated reminder systems prevent unnecessary extensions and significantly reduce administrative work.
