# FP&A for Growing Companies: Budgets, Forecasts and Board Reporting Before a CFO

**Quick answer:** 

> FP&A turns your accounting records into a plan for the year and a running view of whether you're on track. It has four working parts: an annual budget built with department heads, a forecast updated every month or quarter, a monthly comparison of actual results against the budget, and a board pack that explains the gaps. Before a full-time CFO makes sense, FP&A is usually shared between a founder, a finance operations partner that keeps the books reliable, and a fractional CFO who leads the planning.

A growing company can run for a while on a bank balance and a founder's instinct. Then the team passes 20 or 30 people, each department wants more headcount, and the board starts asking whether the plan still holds. Financial planning and analysis, usually shortened to FP&A, is the work that answers those questions. This guide covers what FP&A includes, how to build a budget with your department heads, how the budget connects to the forecast and board reporting, and who should run it before you hire a full-time CFO.

## What does FP&A cover for a growing company?

FP&A covers planning the company's money ahead of time and checking results against that plan. Accounting records what happened. FP&A uses those records to decide what should happen next and to explain why results differ from the plan.

For a company between seed and Series B, the work usually falls into five parts:

| Part                           | What it produces                                                          | How often                                       |
| ------------------------------ | ------------------------------------------------------------------------- | ----------------------------------------------- |
| Annual budget                  | Revenue targets, a headcount plan and spending limits by department       | Once a year, with a mid-year check              |
| Rolling forecast               | An updated estimate of revenue, costs and cash for the next 12 months     | Monthly or quarterly                            |
| Variance review                | Budget against actuals for each department, with reasons for large gaps   | Monthly, after the close                        |
| Board and management reporting | Statements, key metrics, burn, runway and a short written explanation     | Monthly for management, quarterly for the board |
| Scenario planning              | What happens to cash under a slower sales quarter or a faster hiring plan | Before a raise or a large decision              |

FP&A depends on the books being closed on time and recorded correctly. A forecast built on late or wrong actuals carries those errors forward, so the monthly close comes first. Our guide to [what changes in startup bookkeeping after $1M in revenue](https://www.accounti.ai/hub/blog/startup) covers that groundwork.

**What this means for founders:** You can start FP&A with a spreadsheet. What matters early is a reliable close and a budget your department heads helped build, compared with actuals every month.

## How do you build a bottoms-up budget with department heads?

A bottoms-up budget starts with each department estimating what it needs to hit its goals, then adds those estimates into a company total. Department heads understand their own costs better than anyone else, and [budgets built this way tend to be more accurate and give each manager ownership of the numbers](https://corporatefinanceinstitute.com/learn/resources/fpa/bottom-up-budgeting). The risk is time. A growth-stage finance leader writing on budgeting notes that [asking department heads for budgets without top-level targets and limits takes too long to agree](https://buildtoscale.substack.com/p/the-annual-budget), so the strongest process sets a few limits from the top first.

### Six steps that work for growing teams

1. **Set the guardrails.** Leadership agrees on a revenue target, a minimum runway (for example, never below 18 months of cash) and any limit on total headcount. These go to every department head before they start.
2. **Send one template.** Each head gets the same spreadsheet with tabs for new hires by role and start month, software, contractors and programs such as events or paid ads. A shared template means the numbers add up cleanly.
3. **Build revenue from drivers.** Sales and customer success estimate revenue from pipeline, win rates, average deal size and churn, rather than adding a flat growth rate to last year.
4. **Add it up and find the gap.** Finance combines every department's request and compares the total with the guardrails. [Bridgepoint Consulting calls this a gap analysis](https://bridgepointconsulting.com/?p=17192), comparing what departments asked for with what the company can afford.
5. **Review each plan in person.** Each department head presents their budget and explains the trade-offs, with the CEO and finance lead in the room.
6. **Approve and assign owners.** The final budget is locked, and each department head owns their line and explains their own variances every month.

Allow six to eight weeks before the new fiscal year for the whole cycle. Hiring plans take the longest to settle, because headcount is usually the largest cost.

### A worked example

Say a 40-person software company targets $6M in revenue next year and wants to keep at least 18 months of runway. The department requests add up to 22 new hires. At an average fully loaded cost of $150,000 a year, hiring all 22 on January 1 would add $3.3M in annual cost and push runway below the floor.

The gap closes mainly through timing. Sales keeps its four account executives in the first quarter, because revenue depends on them. Engineering moves three of its six hires to the second half, and marketing swaps one hire for a contractor. With start dates spread across the year, the average new hire is on payroll for about six months, so first-year hiring cost lands near $1.65M instead of $3.3M, and runway stays above 18 months.

**What this means for founders:** The value of a bottoms-up budget is in the review conversation. Department heads who defended their numbers in that meeting are far more likely to manage to them during the year.

## How do the budget, the forecast and board reporting connect?

The budget is the fixed plan you set at the start of the year, and the forecast is your updated view of where the year will end. The board report compares actual results with both and explains the difference. [The common pattern is an annual budget that stays locked as the accountability baseline](https://www.getaleph.com/answers/rolling-reforecast-budgeting-tools), with a monthly or quarterly reforecast running alongside it for decisions.

|                         | Budget                             | Rolling forecast                    | Board report                      |
| ----------------------- | ---------------------------------- | ----------------------------------- | --------------------------------- |
| Question it answers     | What did we commit to?             | Where will we actually land?        | How are we doing, and why?        |
| Changes during the year | No, except a formal mid-year reset | Yes, every month or quarter         | New each period                   |
| Built from              | Department plans and guardrails    | Latest actuals plus updated drivers | Closed books, budget and forecast |
| Main reader             | Department heads                   | CEO and leadership                  | Board and investors               |

The monthly cycle runs in a fixed order, starting with the close. Finance then compares actuals with the budget and asks each department head to explain any large gap. Those explanations feed the forecast, because a gap caused by timing gets made up later while a permanent gap changes the year-end number. A useful variance note covers [the cause, whether the gap is timing or permanent, and what it means for the forecast](https://ramp.com/answers/flux-variance-analysis/explain-budget-vs-actual-variances).

The board pack is built on that work. Kruze Consulting recommends that a [startup board package include the three financial statements, a short set of key metrics with burn and runway, and a budget-versus-actual summary with explanations](https://kruzeconsulting.com/blog/startup-board-reporting-package/). Showing actual, budget and forecast side by side lets the board see the original commitment and the current outlook at the same time.

### Explaining a miss to the board

Say revenue for the quarter came in $120,000 below budget. One enterprise deal worth $80,000 slipped from March to April, and churn was $40,000 higher than planned. The board note says the $80,000 is timing and is already signed for April. The $40,000 came from customers who left, and their revenue won't return in later quarters either, so the year-end forecast drops by about $160,000. That covers this quarter's $40,000 plus roughly $40,000 in each of the next three. Leadership is responding by delaying two second-half hires. A short note like this answers the questions a board would otherwise spend the meeting on.

**What this means for founders:** Keep the original budget visible even after it becomes unrealistic. Boards trust a company that reports against its commitment and explains the change more than one that quietly swaps in a new number.

## Who runs FP&A before a company can justify a full-time CFO?

Before a full-time CFO, FP&A is usually split among a few people. The founder or CEO sets the targets and makes the decisions, while a finance operations partner or controller keeps the close on time and the actuals accurate. A fractional CFO, a senior finance leader who works part-time, runs the budget process, the forecast and board materials.

| Stage                | Who runs FP&A                                          | What it usually looks like                                       |
| -------------------- | ------------------------------------------------------ | ---------------------------------------------------------------- |
| Pre-seed and seed    | Founder with a bookkeeper                              | A simple spreadsheet budget, monthly burn and runway             |
| Seed to Series A     | Founder, finance operations partner and fractional CFO | Bottoms-up budget, monthly variance review, quarterly board pack |
| Series A to Series B | Fractional CFO plus a first FP&A or finance hire       | Rolling forecast, department owners, scenario planning           |
| Series B and beyond  | Full-time CFO with an FP&A team                        | Planning cycle, board committees, audit preparation              |

![Who runs FP&A at each startup stage, from founder and bookkeeper at seed to a shared model with a finance operations partner and fractional CFO, then a full-time CFO](https://storage.zerply.ai/teams/319/blogs/526/d240df91be22abd2-1793168417065-accounti-who-runs-fpa-by-stage-2026-10-27-2000w.webp)

Cost explains why the split model lasts so long. A fractional CFO [typically costs $3,000 to $10,000 a month, while a full-time CFO's base salary starts around $195,500](https://taxdome.com/blog/when-small-business-needs-fractional-cfo), before bonus, equity and benefits. One firm estimates [a full-time CFO's loaded cost at $350,000 to $600,000 or more a year](https://taxstra.com/fractional-cfo-vs-full-time-cfo), and adds that it makes sense to hire full time when the work itself is full time.

That point usually arrives when two or more of these are true at once:

- Board and investor work takes more than a few days each month.
- The company runs several entities or has a large debt facility.
- An audit has become a requirement.
- A finance team has formed and needs a full-time leader.

The order of hiring matters as much as the timing. A fractional CFO who spends the first two months fixing the close is doing a controller's job at a CFO's rate. Getting the books reliable first lets planning work start on numbers that hold up. Accounti's Finance Operations does that groundwork for US startups from seed to Series B, keeping the close, reconciliations and reporting ready for budgeting and board review. Our guide to [accounting services for startups by stage](https://www.accounti.ai/hub/blog/best-accounting-services-for-startups) compares the wider options.

**What this means for founders:** Plan to share FP&A across a few people for longer than you expect, and hire a full-time CFO when the finance work fills a full-time role.

## Start with next year's budget

The annual budget is the easiest place to begin, because it forces the conversations FP&A depends on. Set the guardrails, send department heads one template and hold the review meetings. After that, close the books on time every month and compare the results with the plan.

## Frequently asked questions

### What is FP&A in a startup?

FP&A, or financial planning and analysis, is the work of building the annual budget, updating the forecast, comparing actual results with the plan and reporting to the board. Accounting records what happened, while FP&A uses those records to plan what comes next.

### What is the difference between a budget and a forecast?

The budget is the plan approved at the start of the year and stays fixed as the baseline. The forecast is your current estimate of where the year will end, updated monthly or quarterly as actual results come in.

### How long does it take to build an annual budget?

For a growing company, allow six to eight weeks before the new fiscal year. Setting top-level targets first, giving department heads one template and holding a review meeting for each department keeps the process from dragging.

### What should a startup board pack include?

A board pack usually includes the P&L, balance sheet and cash flow statement, a short set of key metrics including burn and runway, and a budget-versus-actual summary that explains the main gaps and what they mean for the forecast.

### When should a startup hire a full-time CFO?

When the finance work fills a full-time role, such as heavy board and investor work, several entities, a required audit or a finance team that needs a leader. Before that, a fractional CFO working with a finance operations partner usually covers FP&A at a much lower cost.
