A Vending Budget Has Several Versions: Identify the Approved Figures Before Ordering
A vending budget can pass through several versions before an order is placed. Supplier quotations change, assumptions are revised and different people make working copies. Before committing expenditure, identify which figures are approved and which are still being explored. The newest file is not necessarily the version the budget owner authorised.
Keep the original approval record and the document it refers to. If the approval names only a total, ask whether it also covers the equipment, services and assumptions in the current proposal. A matching overall amount does not prove that the spending has the same scope or timing as the approved plan.
Give each version a clear purpose
Distinguish working estimates, supplier quotations, comparison scenarios and the approved budget. Use a date or revision reference that people can recognise. Avoid relying on filenames such as “final new final”, which say little about the underlying decision. The person placing the order should be able to identify the authoritative figures without reconstructing an email chain.
Record who prepared the version and why it changed. A short change note might explain that a delivery charge was confirmed or an optional accessory removed. Keep the evidence behind material assumptions. When reviewing vending machine costs, treat general guidance as background and use current written quotations for the actual purchase decision.
Compare changes before requesting approval
Show the difference between the previous approved position and the proposed revision. Include both increases and reductions, as well as items moved between one-off and recurring costs. Do not hide a new commitment inside a lower total created by removing something else. The approver needs to understand what the revised arrangement means in practice.
For a hypothetical example, an estimate could remove €200 of optional equipment while adding a €200 installation charge. The total stays the same, but the scope changes. These invented figures illustrate the review problem, not market prices. Explain the two changes separately so the decision-maker can approve the actual proposal rather than just recognise a familiar total.
Link the order to the approved evidence
Before ordering, check that the supplier quotation, budget version and approval refer to the same configuration and quantities. Verify any expiry or confirmation requirements with the supplier. If something remains provisional, identify it explicitly and agree who can authorise the eventual amount. Do not turn a planning allowance into permission to spend without the organisation’s required approval.
Keep the approved version accessible to the people handling delivery and invoices. They should know which items were included and where exceptions are recorded. If the purchase is split across departments, explain each allocation without duplicating the overall commitment. Refer accounting, tax or contractual questions to the appropriate adviser rather than resolving them through spreadsheet labels.
Preserve the history after commitment
Retain earlier working versions as background but mark them as superseded where appropriate. Do not overwrite the approved record to make it match later invoices. Instead, record subsequent changes and their authorisation separately. That preserves the difference between what was planned, what was approved and what was actually spent.
At the review stage, use those three views to explain variances. An apparent overspend may reflect an authorised scope change, while an unchanged total may conceal a different service package. Clear version control makes the discussion factual and helps the next equipment decision start from reliable information rather than an unexplained collection of old files.
