SaaS
When spend is on budget but new ARR is behind and CAC is higher than planned, the forecast needs to change for revenue, burn and runway together.

Budget variance analysis that explains why you're off plan
Missing the plan is normal. Not knowing why is the problem. Variance analysis should separate timing from real change, and turn the result into an updated forecast.
When actual results keep drifting from the plan
Revenue lands below budget while costs arrive exactly as planned. Gross profit misses even though revenue is on target. The forecast gets updated every month and still misses. Without a proper breakdown, it's impossible to tell whether the plan was wrong or the business changed.
- Revenue below budget with costs fully on plan
- Forecasts that miss month after month
- No way to tell timing differences from real ones
- Budget reports that show variances but no reasons
From variance report to rolling forecast
A budget-versus-actual report is only useful if it explains the gap and changes what happens next. The goal is a forecast you trust more each month.
- 1
Break down each variance
Separate volume, price, mix and cost drivers, and flag which differences are timing and which are permanent.
- 2
Write the commentary
Every material variance gets a reason and an action, not just a percentage.
- 3
Reforecast the rest of the year
Roll the forecast forward with base, upside and downside scenarios built on the drivers that actually moved.
- 4
Track forecast accuracy
Measure how close the forecast was, so the assumptions improve over time.
What drives variances in tech businesses
MSPs
Variances often sit in agreement mix, license costs and technician time. Separating them shows whether it's pricing or delivery.

Split a revenue miss into utilization, billable rate and headcount, and show how fixed-fee overruns flow into margin and the forecast.

What should a budget-versus-actual report include?
Actuals, budget, variance and the latest forecast, plus the reason for each material variance and what is being done about it.
How accurate should a small company's forecast be?
Within a few percent on costs and a wider band on revenue. What matters more is understanding why it missed and whether the miss is shrinking.
Revenue is on plan but gross profit is below budget. Why?
Usually pricing, customer or product mix, or higher delivery costs. A margin bridge from budget to actual shows which one.
How do I build base, upside and downside scenarios?
Start from the drivers that moved, change them in a controlled way, and show each scenario's effect on profit and cash, not just revenue.
What is a rolling forecast?
A forecast that always looks the same distance ahead, for example 12 months, and is updated with actuals each month instead of once a year.
How should a SaaS company reforecast when new ARR is behind plan?
Reset new ARR and CAC to what the data shows, then flow the change through revenue, burn and runway before deciding on spend.
How do I separate utilization from rate in a revenue miss?
Recalculate revenue at plan rate with actual hours, then at actual rate. The difference between the steps shows how much each driver contributed.
