B2B terms of sale set the default conditions for all contracts with business customers. They must be incorporated before or at the time of contracting — not afterwards. The Unfair Contract Terms Act 1977 (not Consumer Rights Act) applies.

• Must be incorporated before or at point of contract
• Reasonable notice required of exclusion clauses
• Late Payment of Commercial Debts Act: 8% above base rate
• Retention of title (Romalpa clause) protects unpaid supplier
• UCTA 1977 — exclusions must be reasonable

Legal reference: Unfair Contract Terms Act 1977; Late Payment of Commercial Debts (Interest) Act 1998; Sale of Goods Act 1979
