Budgeting, forecasting, and variance analysis

Direct answer

For this review, define SMB FP&A as budgeting, forecasting, driver-based planning, variance analysis, and decision support.

Why this question comes up

Growing companies need planning discipline before they can justify enterprise FP&A software. This guide turns that concern into a review that can be repeated with a defined period, consistent inputs, and a visible trail back to the records.

Records to gather

• The approved budget with its version, date, and approver
• Actuals for the same period on the same accounting basis
• Any reforecast, with what changed and why
• Chart-of-accounts mapping if budget and actuals use different structures
• Documented materiality thresholds for investigation

Review workflow

1. Set materiality before you look. Decide the threshold — a percentage, an absolute amount, or both — in advance. Choosing it after seeing results invites explaining away whatever is inconvenient.
2. Confirm budget and actuals are comparable. Same period, same entities, same accounting basis, same account structure. A mapping difference produces variances that are pure artefact.
3. Split price from volume. A revenue miss because you sold fewer units is a different problem from one because you discounted. The combined variance hides which.
4. Separate timing from permanent. A bill arriving a month late creates an overspend this month and an underspend next. Only permanent variances need a plan.
5. Trace to transactions. A variance explanation that stops at the account level is a restatement of the number, not an explanation.
6. Assign an owner and a date. A variance without someone accountable for the response recurs next period unchanged.

What a useful answer should include

• Budget, actual, variance in currency and percent, for the same scope
• The materiality threshold, stated up front
• Price/volume decomposition for revenue variances
• Timing versus permanent classification for each material item
• The transactions or drivers behind each material variance
• An owner and a follow-up date per item requiring action

Common failure modes

• Explaining every line. Without a threshold, review time goes to trivia and the material items get the same weight as noise.
• Comparing incomparable structures. A reorganised chart of accounts produces large variances that mean nothing.
• Reporting combined revenue variance. Price and volume have different causes and different fixes.
• Treating a timing difference as performance. It reverses next period and misdirects the response.
• Explanations that restate the number. “Marketing was over budget because we spent more on marketing” is common and useless.
