#Budget overview
A budget is a forward-looking plan of expected revenues, expenses, and capital expenditures. Budgets serve several purposes:
- Financial planning: Projecting cash needs and profitability
- Performance management: Setting targets and evaluating actual performance
- Resource allocation: Determining spending limits by department
- Scenario analysis: Modeling impact of different business assumptions
Light allows multiple budgets (annual budget, quarterly forecast, departmental budgets) and comparisons between them.
#Creating a budget
To create a budget:
- Navigate to Planning & Reports → Budget
- Enter budget details:
- Budget name (e.g., "FY2025 Annual Budget")
- Period start and end (fiscal year or custom period)
- Level of detail: By account, account type, cost center, business partner
- Select budget scenario: Base case, optimistic, pessimistic, or custom
- Light displays budget input interface
- Enter budgeted amounts for each account/period
- Save the budget
Budgets can be entered manually or imported from Excel or other sources.
#Budget levels and dimensions
Configure budget detail level:
Account-level budgets: Budget each GL account separately (high detail, time-consuming).
Account type budgets: Budget by expense category (revenue, COGS, operating expense). Higher level, faster to create.
Cost center budgets: Budget by department (useful for management accountability).
Business partner budgets: Budget by customer revenue or vendor spending.
Multi-level budgets: Combine dimensions. For example:
- Row: Expense accounts
- Column: Departments (cost centers)
- Result: A matrix where each cell is a specific account's budget in a specific department
Tip: Start with account-type budgets (high-level), then drill down to account detail for significant items.
#Budget templates
Create reusable budget templates:
- Set up your standard budget structure (accounts, periods, cost centers)
- Click Save as Template
- Next budget season, create new budget from template
- Adjust figures based on updated assumptions
This saves setup time year-over-year.
#Bottom-up vs. top-down budgeting
Light supports both approaches:
Top-down budgeting:
- Executive leadership sets overall revenue target
- Overall profit margin target
- Finance distributes targets to departments
- Departments build detailed budgets to targets
- Finance consolidates and reviews
Bottom-up budgeting:
- Each department builds budget from operational assumptions
- Each salesperson estimates revenue
- Each manager estimates spending
- Finance consolidates bottom-up estimates
- Compare to targets and reconcile differences
Light facilitates both: Enter top-down targets or import bottom-up submissions.
#Budget assumptions and drivers
Effective budgets are built on explicit assumptions:
Revenue assumptions:
- Growth rate (% increase from prior year)
- New customer additions
- Churn/retention rates
- Average selling price
- Product mix
Expense assumptions:
- Headcount (number of employees)
- Salary growth rate
- Fixed vs. variable spend
- CapEx requirements
Document assumptions in budget narratives. When actual results differ from budget, revisit assumptions to understand drivers.
#Forecasting and rolling forecasts
Beyond annual budgets, maintain forward-looking forecasts:
- Create a rolling forecast (12-month forward-looking view)
- Each month, add a new month to the forecast
- Update forecast monthly based on actual performance and market changes
- Compare actual vs. forecast to track accuracy
Rolling forecasts are more responsive than annual budgets.
#Scenario analysis
Model different "what-if" scenarios:
Base case: Most likely scenario with realistic assumptions.
Optimistic case: Higher growth, lower costs, better customer retention.
Pessimistic case: Lower growth, higher costs, higher churn.
Stress case: Severe recession or major business disruption.
Compare scenarios to understand:
- Upside and downside potential
- Key drivers of outcomes
- Financial impact of assumptions changing
Light lets you create multiple scenarios and compare them side-by-side.
#Budget vs. actual analysis
Once actual results are recorded, compare to budget:
- Navigate to Planning & Reports → Reports
- Select budget and actual period
- Light displays budget, actual, and variance ($ and %)
- Highlight variances >threshold (e.g., >10%)
Investigate significant variances to understand what drove differences:
- Did we achieve revenue targets?
- Did expenses stay within budget?
- What changed from plan and why?
#Rolling forecasts and reforecasting
During the year, forecasts may need updating:
- Each quarter, create an updated forecast for the remainder of the year
- Incorporate actual results year-to-date
- Update assumptions based on market changes
- Reforecast full-year results
This is more responsive than a static annual budget.
Create reports showing budget performance:
- Variance report: Actual vs. budget by account
- Variance trend: Variances over time (are they improving?)
- Responsibility accounting: Actual vs. budget by cost center (for management accountability)
- Segment budget: Budget by customer, product, or geography
These reports support management discussions and decision-making.
#Budget allocation and resource planning
Use budgets for resource decisions:
Headcount planning: Plan headcount by department, multiply by average salary to determine budget.
Capital planning: Plan major asset acquisitions and their impact on depreciation.
Marketing spend: Budget by channel (digital, sales, events) to optimize ROI.
Light helps model these allocations and their P&L impact.
#Consolidating departmental budgets
For multi-department organizations:
- Each department manager submits budget (bottom-up)
- Finance consolidates all departmental budgets
- Compare to corporate targets
- Reconcile differences
- Get executive approval
Light consolidates budgets automatically across departments and entities.
#Budget vs. actual by cost center
Assign accountability using cost center budgets:
- Create budget by cost center (department)
- Allocate cost center to transactions as they're recorded
- Compare actual by cost center to budgeted by cost center
- Department managers are accountable for their cost center performance
This supports responsibility accounting and management accountability.
#Capital expenditure budgeting
Plan for asset purchases separately:
- Create CapEx budget with planned asset purchases
- Schedule over periods (monthly, quarterly)
- Track actual CapEx spend against budget
- Project depreciation impact on future P&L
Light helps manage capital projects and their financial impact.
#Multi-currency budgeting
For multinational organizations:
- Create budgets in each entity's functional currency
- Consolidate to group currency using budgeted FX rates
- Compare actual (translated) to budget (translated at budgeted rates)
- Analyze FX variance separately
This shows impact of FX assumptions on profitability.
#Budget approval workflow
Establish a budget approval process:
- Department managers submit budgets
- Finance reviews for completeness and reasonableness
- Consolidate across departments
- CFO and executive team review and revise
- Board approval
- Final budget locked for the year
Light tracks who created, reviewed, and approved each budget.
#Linking budgets to planning
Use budgets as input to broader planning:
Cash flow planning: Use budgeted P&L to project cash flows.
Funding planning: If cash flow is negative, plan for financing.
Headcount planning: Align budgeted spending with hiring plans.
Capital planning: Plan for major asset purchases and their financing.
Light integrates budgets with other planning tools.
#Budget accuracy and variance trending
Track budget accuracy over time:
- After each fiscal year, compare budget to actual
- Calculate variance percentage
- Identify which accounts/departments were over/under budget
- Learn from variances to improve future budgets
Light trends this data, showing whether budget accuracy improves over time.
Tip: Variances of 5-10% are normal. Investigate variances >15% to identify process breakdowns or assumption changes.
#Budget templates for recurring transactions
For recurring items (rent, salaries, utilities):
- Create a template showing typical monthly amounts
- Adjust for known changes (salary increases, new hires)
- Replicate across months
- Reduces manual entry
Light supports template-based budget entry.
