A public procurement value needs its stage and source context before it can answer a research question. A tender figure, an award figure and evidence of payment should not be treated as interchangeable. The Open Contracting Data Standard’s process model helps organize the distinction. This article explains record interpretation; it provides no financial judgement about an actual supplier and reports no verified expenditure.

Use the stage shown by the source

The OCDS process primer, checked on 3 October 2026, distinguishes tendering, awarding, contracting and implementation. Its descriptions include values at more than one stage, while implementation includes payment, progress and completion information. The presence of an earlier-stage value consequently does not by itself answer whether work was completed or a particular amount was paid.

Define the question before extracting numbers

Write the research question in plain language. Is the reader asking what was proposed, what outcome was announced, what the signed record shows or what implementation evidence was published? An illustrative extraction sheet should name that question beside the field being collected. This keeps a readily available number from substituting for a different fact that is missing.

For a hypothetical procurement, an award announcement could be available while implementation information is absent. The responsible conclusion would describe the award evidence and the missing later-stage information separately. It would not translate the award figure into a claim that the supplier received the same amount or finished the work.

Retain the source path and context

Record the exact source field or document section, retrieval date and process reference beside the value. Keep the amount and its stated currency together. If the source uses a range, estimate or description rather than a single confirmed figure, preserve that form. Do not convert it into an invented precise amount merely because a spreadsheet expects a number.

A working comparison should also keep the stage labels attached after sorting or exporting. A column called value can obscure material differences between records. Rename the working column to reflect what it actually contains, or add an explicit evidence-stage column. These are research controls rather than accounting rules.

Do not turn missing implementation data into a verdict

If payment or completion information was not found, record the search scope and gap. A missing public field does not independently establish nonpayment, unfinished work, fraud or poor supplier performance. The publisher may disclose information elsewhere, later or under a different structure. An adverse conclusion needs relevant evidence and appropriate human review.

The useful output is a bounded comparison

Our editorial recommendation is to compare like-stage evidence and report unresolved differences openly. A short table with accurate labels is more useful than a larger total assembled from unlike figures. No dataset or contract was audited for this article. Applying the method to a real procurement requires publisher-specific definitions, current source records and review of any actual financial or performance conclusion. The standard supplies a framework for evidence, not a guarantee of data completeness.
