Financial planning and budget structure
How to write an event budget approval memo
The budget is built, and now someone with authority has to say yes, in writing, without a meeting to walk them through every line.
Opens WhatsApp with a draft you can edit before sending. Nothing is sent automatically.
The short answer
An approval memo states the decision requested, the total, what is in and out, the assumptions behind it, the unresolved questions and the date by which a decision is needed. It is short enough to read in five minutes.
The approver should be able to say yes, no, or yes subject to conditions from the memo alone. Detailed lines sit in an attached schedule, not in the memo body.
Start with the decision, not the background
Open with one sentence: approve a budget of a stated amount, for a named event, to be committed by a stated date. If the request includes a reserve or a funding source, say so in the same sentence.
Background follows in a short paragraph. The approver should not need to read it to know what is being asked.
Sections of the memo
| Section | What it holds | Common gap |
|---|---|---|
| Decision requested | Amount, scope, commit-by date, approver name. | Amount given without saying what it includes. |
| What is included | Categories and their totals, taken from the attached schedule. | Totals that do not match the schedule. |
| What is excluded | Items outside the request, for example costs borne by another department. | Exclusions left for the approver to discover. |
| Tax and service charges | State the treatment as the quotations show it, and note that finance confirms it. | Mixing quotes that include and exclude them. |
| Assumptions | Headcount, date, venue, quotation status, planning rates where relevant. | Assumptions buried in notes. |
| Reserve | Amount, basis and who releases it (see contingency allowance). | A reserve hidden inside lines. |
| Open questions | What is not yet known, with owner and date. | Unknowns presented as settled. |
| Funding and cash timing | Source of funds and when the largest payments fall. | Approval with no view of cash timing. |
Build it in order
- Finish the budget schedule first, with every line sourced from a quotation, estimate or past record, labelled as such.
- Use the approval summary builder or the budget builder to generate a summary that reconciles with the schedule.
- Write the decision sentence, then the included and excluded lists.
- List assumptions and open questions, each with an owner and a date.
- Ask finance to read it for consistency. Leave the approval block blank for the approver to complete.
Keep the memo honest
- Label estimates as estimates. Do not present a figure as quoted if it is indicative.
- Do not write that finance has approved or reviewed anything unless it has, in writing.
- State the cancellation position of major commitments so the approver knows what is reversible.
- If the budget is conditional on a funding outcome, write the condition into the decision sentence.
Worked example · Fictional example
A memo opening and decision block
Fictional organisation and figures, illustrative only. The approval block is shown unsigned.
A fictional professional association asks its executive committee to approve a budget of RM 148,000 for its annual conference, including a reserve of RM 7,000, with major supplier commitments to be signed by 15 March.
The memo excludes secretariat staff time, notes that tax and service charges follow each quotation's stated treatment pending finance confirmation, and lists two open questions: final headcount range and the AV quotation, both owned by the conference chair with a decision date.
| Item | Entry |
|---|---|
| Decision requested | Approve RM 148,000 including RM 7,000 reserve, commit by 15 March |
| Excluded | Secretariat staff time; sponsor-funded items |
| Open question 1 | Headcount range, owner: conference chair, by 1 March |
| Open question 2 | AV quotation, owner: programme lead, by 28 February |
| Approval | Approved / approved with conditions / not approved. Name, signature and date to be completed by the approver |

Handle it in-house, or bring in help?
Your team can usually handle this when
- The budget schedule is complete and reconciles to the quotations.
- The approver knows the event and wants a short, decision-ready memo.
- Finance is available to read the memo for consistency.
Outside planning help earns its fee when
- Several approvers or committees must sign, each wanting a different view of the same budget.
- The budget has many open questions and needs structured scoping before a memo can be written.
- A funder or board expects a documented trail that stands up to later review.
Need the approval pack put together for the committee?
An Event Blueprint can produce the budget schedule, the assumptions and open questions and a draft memo ready for your approver, with each line traceable to a quotation or estimate. A project lead can then chase the open items to their decision dates. Approval and any finance sign-off stay with your organisation.
Questions organisers ask
How long should the memo be?
One to two pages, plus an attached schedule. If the approver cannot decide from the first page, move detail into the schedule.
Should I ask for approval before quotations arrive?
You can, if the memo labels estimates clearly and states which figures are open. Many committees approve a ceiling and release commitments as quotations firm up.
Who should sign the memo?
The person your governing document or delegation names as the budget approver. If unsure, ask your secretary or finance contact. Do not complete the approval block on anyone's behalf.
