Service credits are financial compensations provided to the buyer when the supplier fails to meet the agreed- upon service levels outlined in the SLA. They serve as a remedy for underperformance. Service guarantees are commitments to meet certain standards, service standards define the expected level of service, and service schedules outline the timing of service delivery, but none directly compensate the buyer for service failures.
Reference:CIPS L4M3 Commercial Contracting Study Guide, Chapter 2, Section 2.2.2 - The use of service level agreements (SLAs).

Exporting enterprises must sometimes incur additional costs as they adapt their production to the changing legal requirements of the recipient country. Such requirements can thus create technical barriers to trade. Discrepancies between product rules adopted by different countries can involve numerous aspects: weight, size, packaging, ingredients, mandatory labeling, shelf-life conditions, testing and certification procedures etc.
One way to overcome these barriers is to adopt international standards. Overseas companies may be more familiar with international standards without looking at specific regulations of importing countries.

When a party takes on a contractual obligation, they are legally required to perform the obligation.
That same contracting party is still entitled to subcontract out the work to another service provider, unless the contract:
- is a contract for personal services, such an employment contract
- contains an express term preventing subcontracting out the work, or an implied term Subcontracting clauses are written to control whether the contractor is entitled to subcontract, and how purchaser shall control that subcontracting process.

Modern Slavery (C) and Sustainability (D) are core social and environmental issues under ESG and ethical procurement policies.
Indemnity and warranty are legal clauses, not social or environmental considerations.

Early market dialogue is used to explore supplier capabilities and gather ideas, particularly in complex or innovative services. Discussing service innovation with suppliers helps the buyer shape better specifications and outcomes. Topics like pricing and contract terms should remain within formal procurement stages to ensure fairness.
