Key takeaways
- The AOP should be built bottom-up (from operational drivers) and reconciled top-down (against strategic targets); plans built top-down only produce targets without credibility; plans built bottom-up only may understate what the business is capable of.
- Revenue build is the most important and most frequently underdeveloped AOP component, a credible revenue plan accounts for existing customer growth, new customer acquisition (by sales rep and pipeline), and churn, not just a percentage applied to prior year revenue.
- The AOP process should begin 10-12 weeks before fiscal year-end and involve department heads, not just finance; plans built by finance in isolation are not owned by operators and will not be executed.
- A good AOP becomes irrelevant without a monthly review cadence that compares actuals to plan and updates the forward forecast; the AOP is the baseline, not the destination.
What makes an operating plan useful vs. performative
Most middle market companies produce an annual budget. Far fewer produce a genuine operating plan. The difference: a budget is a financial forecast; an operating plan is a financial forecast tied to specific operational decisions about headcount, capital deployment, sales coverage, and operational investments.
A budget answers: "What will our P&L look like next year?" An operating plan answers: "What decisions are we making about headcount, spending, and growth investment, and what financial outcome do those decisions produce?"

The revenue build: the most important and most underdeveloped section
Revenue forecasting is where most AOPs fail. The typical approach, take last year's revenue, add a growth percentage, and call it a plan, produces a number without a mechanism. If you cannot explain where every dollar of planned revenue is coming from, the forecast is not a plan.
A credible revenue build has four components: existing customer retention and growth (what is your renewal rate, what are average expansion rates per customer, what customers are at-risk), new customer acquisition (how many new customers will the sales team close, at what average contract value, from what pipeline), pricing changes (are you implementing any price increases, and what is the assumed impact), and product mix shifts (are any products or services growing faster or slower than average).
Start with existing revenue
Map every current customer's renewal date, renewal probability, and expected contract value at renewal. Sum to get the retained revenue base.
Add expansion
For customers with multi-product or multi-site potential, model the expansion opportunities. Use historical expansion rates as a baseline.
Model new customer acquisition
Work with the sales leader to build a bottoms-up new logo forecast by sales rep, based on pipeline and historical close rates.
Apply pricing assumptions
Overlay any planned price increases on the retained base.
Stress-test the result
Apply a 10-15% downside to the new logo forecast, this is almost always the highest-variance component.
Headcount plan: the AOP component that most affects EBITDA
In most middle market service, software, and professional services businesses, headcount is 40-65% of total costs. The headcount plan, who is hired, when, in what role, and at what cost, is therefore the most impactful cost decision in the AOP.
A credible headcount plan includes: current headcount by department, planned new hires by role (with start dates and annualized cost), planned departures (voluntary attrition assumption), and a reconciliation showing how headcount changes drive cost changes in the P&L.
The most common headcount plan error: planning all new hires for Q1 when they realistically will not be hired until Q2 or Q3. This overstates costs in Q1 and understates them later, producing variance that has nothing to do with business performance. Plan new hires conservatively by timing, and variance analysis will be cleaner throughout the year.
Companies with integrated headcount plans (linked HR and finance data, updated monthly) achieve 30-40% higher accuracy on total cost forecasts vs. companies that plan headcount and costs separately.
PE-backed companies with a formal AOP process approved by the board before fiscal year-start have 25% higher on-plan achievement rates than companies operating without a formally approved plan.

The AOP is not a finance exercise. It is a management alignment exercise that happens to produce financial outputs. If department heads did not own their portion of the build, they will not feel accountable to the outputs. The CFO can build a technically perfect plan in isolation, but if operations does not own the headcount assumptions and sales does not own the revenue build, the plan will be ignored by February.
Build the revenue line by naming every customer and every dollar. A revenue plan that cannot identify where specific growth is coming from is not a plan. It is a target. Targets without mechanisms are wishes.
