⚠️ Why Payment Terms Must Be Clear
Vague payment terms like "payment on receipt" or "payment when convenient" are unenforceable and leave you vulnerable to indefinite payment delays. UK contract law requires certainty - you must specify an exact payment deadline (e.g., "30 days from invoice date" or "14 days from delivery"). Without clear terms, customers can argue they had reasonable time to pay, which courts may interpret as 30+ days.
Specific Payment Due Period
Exact timeframe when payment is due (e.g., 7 days, 14 days, 30 days, 60 days). Essential for enforceability under UK contract law. Vague terms like "immediately" or "promptly" are unenforceable.
