How Much Should A Startup Spend On Accounting

If you’re building your first real budget, how much should a startup spend on accounting is one of the few numbers you actually need before you can plan anything else. The short answer is a percentage of revenue, but a percentage alone doesn’t tell you what to write on a spreadsheet, so let’s get to an actual dollar figure.

How Much Should a Startup Actually Budget for Accounting?

Most startups should plan to spend somewhere between 2% and 5% of revenue on accounting. That range comes from Milestone’s own experience working with early-stage companies, though other sources land closer to 1% to 3%, so treat it as a general industry range rather than a fixed rule. Where you fall in that range depends mostly on your transaction volume and how much complexity your business carries.

What Does That Percentage Look Like in Real Dollars?

Say your startup is bringing in $50,000 a month in revenue, or $600,000 annualized. At 3%, roughly the middle of that range, you’re looking at about $1,500 a month. For a company at that stage with a moderate transaction volume, that figure covers weekly bookkeeping, bank and credit card reconciliations, and a monthly close with basic reporting, without yet stretching into forecasting or FP&A work. This is one illustrative example, not a quote, but it gives you a real number to check your own budget against.

What Factors Push Your Accounting Costs Higher or Lower?

Transaction volume is the biggest driver. A startup processing a few hundred transactions a month costs less to keep clean than one processing several thousand, regardless of revenue. Industry matters too: regulated sectors like healthcare, finance, or anything handling sensitive data usually carry higher compliance overhead, which pushes costs toward the top of the range. The last major factor is whether you handle accounting in-house or outsource it, since that decision changes both the cost structure and what you get for it.

Does In-House or Outsourced Accounting Cost Less?

Neither wins outright. An in-house hire means salary, benefits, and payroll taxes on top of the base pay, often putting a single full-time bookkeeper or controller well past what most early-stage startups would spend outsourcing the same scope. Outsourced accounting trades that fixed overhead for a service fee that scales with what you actually need, but you give up having someone physically embedded in your day-to-day operations. Many startups outsource in the early stages specifically because the fixed cost of an in-house hire doesn’t match unpredictable early revenue.

What Should You Actually Get for What You’re Spending?

Your accounting spend should map to a real scope of work, not a vague retainer. At minimum, that means weekly bookkeeping and reconciliations, so your books stay current instead of piling up. It should also include a monthly close and reporting package, so you have accurate financials on a predictable schedule rather than scrambling before tax season. As your startup matures, that scope expands to include cash flow forecasting, so you can see runway and burn rate coming before they become a problem.

When Does It Make Sense to Add Forecasting and FP&A to Your Budget?

Two triggers usually signal it’s time. The first is an approaching fundraise, since investors expect to see forecasts and scenario modeling, not just historical statements. The second is needing board-level reporting, once you have a board that expects KPIs and financial context beyond a basic profit and loss statement. Before either of those triggers, basic bookkeeping and monthly close usually cover what you need.

How Do You Know If You’re Overspending or Underspending on Accounting?

Underspending tends to show up as chaos: books that fall weeks behind, surprises at tax time, and no real-time visibility into your cash position. Overspending looks different. It usually means paying for forecasting, FP&A, or a fractional CFO before you have the fundraise, board, or complexity that actually needs it, which is money better spent elsewhere at that stage.

What Are the Warning Signs of Underinvesting in Accounting?

Watch for late monthly closes that slip further behind each cycle, tax filings that turn into scrambles because nothing was reconciled along the way, and not knowing your cash position without pulling numbers manually. Any of these usually means your current spend, whatever percentage it works out to, isn’t buying enough.

How Can You Budget for Accounting as Your Startup Grows?

Your accounting budget should shift in stages, not jump straight to a full package. Early on, that spend covers basic bookkeeping and monthly close. As you approach a fundraise or bring on a board, it typically expands into budgeting, cash flow forecasting, and eventually fractional CFO support, each layered in as the actual need shows up rather than paid for in advance.

Milestone’s accounting and forecasting services are built to scale this way, from weekly bookkeeping through full budgeting and forecasting support, so your spend maps to what your startup actually needs at each stage instead of a flat package priced for a company further along than you are. If you’re building this budget now, Milestone’s budgeting and forecasting services can help you figure out where your startup falls in that range and what to spend it on.
