Budget planning estimates the quantities, prices, people and timing required to execute a business objective. A useful process has six stages: direction, assumptions, departmental proposals, reconciliation, approval and operational handover. Each needs a deliverable and a reviewer.
This guide focuses on execution. Use the budget formulation guide for responsibilities and the marketing budget guide for estimation methods.
Six stages and their outputs
Stage | Work | Completion evidence |
|---|---|---|
1. Direction | Set period, objectives, limits and priorities | Approved planning brief |
2. Assumptions | Review contracts, rates, volumes and capacity | Shared assumption register |
3. Departmental proposals | Build monthly activity and cost plans | Proposal with supporting evidence |
4. Reconciliation | Resolve duplication, funding limits and dependencies | Reconciled scenarios and open issues |
5. Approval | Present alternatives, risks and requested decisions | Approved version and conditions |
6. Handover | Set actuals close, variance review and forecast updates | Tracking process, owners and calendar |
Submission alone is not completion. Check arithmetic, evidence, uncertainty and the required decision. Give every unresolved issue an owner and deadline.
Work backward from approval
For a fictional company beginning its fiscal year in April, January may cover direction and departmental proposals, February reconciliation and downside alternatives, and March final review and handover. Major investments or hiring may require an earlier start.
Schedule supplier quotes and cross-functional inputs before the meetings that depend on them. Circulate evidence in advance so that a review meeting resolves decisions rather than discovering missing assumptions.
Assumption | What to record | Owner |
|---|---|---|
Staffing | Planned start dates, counts and hiring certainty | Department leader |
Prices | Quote, contract term and renewal conditions | Procurement |
Activity | Deliverables, events or lead volumes and delivery capacity | Activity owner |
Revenue timing | Booking, recognition and payment assumptions | Sales and finance |
Separate confirmed commitments from estimates. Adding decimal places to an unsupported assumption does not improve confidence.
Keep rolling forecasts distinct from budget amendments
A rolling forecast updates the outlook over a moving future horizon using recent actuals. It does not automatically change spending authority. If the term “rolling budget” is used internally, specify whether it includes a formal change to approved allocations.
Version | Purpose | Control |
|---|---|---|
Original budget | Compare with the initial approval | Retain unchanged |
Revised budget | Reflect formally authorized changes | Record approval and reason |
Actuals | Report confirmed period results | Keep close and correction history |
Latest forecast | Estimate the likely outcome | Record assumptions and update date |
For example, an annual budget of JPY12 million, three months of actual spending of JPY2.7 million and a remaining forecast of JPY9 million give a JPY11.7 million full-year outlook. The −JPY300,000 variance does not mean the approved budget has changed.
Reconcile choices, then hand over the process
Before applying uniform cuts, separate committed and discretionary costs, immediate activity and longer-term capability, and dependencies on sales, production or development. State what a reduction would stop and how the outcome or delivery date would change.
At handover, confirm the version, approval date, owner, recognition rules, close deadline, variance-review criteria and amendment authority. A spreadsheet can work when scope and ownership are manageable. Consider a new tool when measurable problems in consolidation, permissions or version control justify it.
