Specify the exchange
List goods, services, quantities, expected quality and dates. Promised visibility needs a scope: medium, duration and placement. Identify who can commit each organisation and what approvals are required before treating an informal discussion as an agreed delivery.
Calculate real cost
Include production, labour, transport and forgone opportunities. A partner’s stated valuation is not automatically value received. Compare what you would genuinely have purchased rather than adding up catalogue prices for services you did not need.
Prepare delivery terms
Write acceptance criteria, discrepancy handling and responsibilities. Review rights and appropriate declarations with accounting and legal functions. Lack of a cash transfer does not mean there are no obligations. Preserve agreed terms and subsequent changes.
Review the outcome
Retain deliverables, dates and observed results. Separate measured benefit from estimates. If received services were not used, explain that instead of treating their entire advertised value as a realised saving.
