Online bookkeeping services are firms that keep your books remotely, pairing software with a human team that categorizes transactions, reconciles accounts, and closes each month for you. Entry-level plans start around $99 per month, and the outsourced bookkeeping layer typically runs $500 to $2,000 per month once you need accrual accounting and a named bookkeeper.
That is the answer most people are looking for. The more useful question is what the service model does to your finance function over the following year, because the pricing page and the lived experience diverge in three predictable places. This guide covers the cost tiers, the structural trade-offs, when a service is the right call, and what an always-current alternative looks like. It is part of our bookkeeping for startups hub.
What do online bookkeeping services cost?
Published pricing in this category is tiered by transaction volume or monthly expenses, and the tiers move quickly.
Pilot's published pricing is representative of the shape. Its Essentials plan is $99 per month for companies under $100,000 in monthly expenses and covers cash-basis bookkeeping from bank and card feeds on a standard chart of accounts. Its Core plan starts at $299 per month billed annually, and that is where the things most funded startups actually need appear: a US-based bookkeeper, accrual-basis accounting, a custom chart of accounts, and bill management for up to ten vendor bills per month.
The broader market lines up with that. Eightx's 2026 pricing guide puts a bookkeeper at $500 to $2,000 per month and a controller at $2,500 to $7,000 per month, with the controller layer being the one that owns monthly close accuracy. Add the strategic layer on top and the numbers climb again: Graphite Financial reports that fractional CFO hourly rates in 2025 and 2026 run $175 to $450 per hour, which is why forecasting and board prep almost never sit inside a bookkeeping retainer.
| Layer | Typical monthly cost | What it covers |
|---|---|---|
| Entry-level online bookkeeping | $99 to $299 | Cash-basis categorization and reconciliation, standard chart of accounts, year-end package |
| Full-service outsourced bookkeeping | $500 to $2,000 | Accrual accounting, named bookkeeper, custom chart of accounts, limited bill handling |
| Controller layer | $2,500 to $7,000 | Owns the monthly close, technical accounting, compliance |
| Fractional CFO layer | $3,000 to $12,000 | Forecasting, scenario planning, board and investor reporting |
The reason the stack looks like this is that the service model prices human hours. Every additional thing you want done is another person's time, so it is another line item. That is not a criticism of any particular firm. It is the arithmetic of selling labor.
Where does the service model strain?
Three trade-offs are structural rather than vendor-specific, and they are the ones worth understanding before you sign.
Your books arrive on the service's cycle, not yours. Pilot publishes reports on the tenth business day for Core customers and the sixth business day on custom plans. That is a genuinely good close cadence by industry standards. It also means that on the ninth of the month you are making decisions against August's numbers, and by the twentieth you are working from data that is three weeks stale. If you are burning $180,000 a month, three weeks of drift is real money moving without a current picture behind it. We wrote about this gap in more detail in our comparison of AI bookkeeping and outsourced bookkeeping.
The price scales with the things you want more of. Tiers key off monthly expenses, transaction counts, or connected accounts. Growth is the exact condition that moves you up a tier, so the quarter where you most need budget discipline is the quarter your bookkeeping bill increases. Bill handling caps work the same way. Ten vendor bills a month is fine until you take on a roster of contractors and it is not.
Scope boundaries sit exactly where the useful work starts. Bookkeeping retainers cover recording and reconciling. Forecasting, runway scenarios, board decks, and investor reporting are separately priced, typically at the controller or CFO rates above. The result is a common pattern: startups buy clean historical records and then discover that nothing in the package answers "can we afford this hire in November?"
When is an online bookkeeping service the right call?
Often, honestly. A few situations where a service is clearly the correct purchase:
- You need a cleanup. Eighteen months of uncategorized transactions and a broken chart of accounts is a project, and project work is what firms are good at.
- You have unusual entity complexity. Multi-entity consolidations, foreign subsidiaries, and complicated equity histories benefit from a specialist who has seen yours before.
- You want tax filing and bookkeeping from one vendor. Several providers bundle these, and the coordination savings are real.
- You genuinely have low volume and low stakes. A pre-revenue company with forty transactions a month does not need a finance function. It needs someone to keep the ledger tidy for the eventual tax return.
Pilot, Zeni, and Fondo are the names that come up most often in this category for venture-backed companies, and each has a compare page on this site if you want the detail. Our Pilot comparison goes deepest on the close-cycle question.
What does the alternative look like?
The alternative is not a cheaper bookkeeper. It is a different operating model: instead of buying a monthly delivery cycle, you run a finance function that works continuously on one ledger and produces the same picture every time you look at it.
That is what Futureproof is. Six agents work your books as transactions land rather than in a batch at month end. Vic keeps the ledger and the close moving, Remi chases receivables, Theo captures costs and bills, Margo runs forecasting and scenarios, Hugo watches revenue metrics, and Nia covers investor and board reporting. Everything sits on a single source of record, so the forecast is built from the same ledger the close is built from, not from a spreadsheet that someone exported on the eighth.
Pricing is $1,000 per month flat. That covers all six agents, and it includes a monthly review call with a human financial specialist. There is no per-seat fee, no transaction tier, and no separate line item when you want a forecast or a board packet. Growth does not reprice you.
| Online bookkeeping service | Futureproof | |
|---|---|---|
| How work happens | Batch close on the service's monthly cycle | Continuous, as transactions land |
| When numbers are current | Reports on the sixth to tenth business day | Any day you open them |
| Pricing basis | Tiered by expenses, transactions, or connections | $1,000 per month flat |
| Forecasting and scenarios | Separate engagement at controller or CFO rates | Included |
| Board and investor reporting | Separate engagement | Included |
| Human review | Varies by tier | Monthly call with a financial specialist, included |
| Books | CPA-ready | CPA-ready |
This replaces the finance team, not the finance leader. If you have a CFO, a VP of Finance, or a fractional CFO, the agents work underneath them and give them a current ledger to lead from. If you are weighing a strategic hire separately, our guide to virtual CFO services covers what that layer is actually worth paying for.
How should you decide?
Two questions settle it for most founders.
First, how often do you need to make a decision against current numbers? If the answer is once a quarter, a monthly close on a ten-day lag is fine and a service is a reasonable buy. If the answer is weekly, you are going to spend the year building shadow spreadsheets to bridge the gap, and you will be paying for the service anyway.
Second, what happens to your bill in twelve months? Model your expected transaction volume and expense base against the vendor's tiers before you sign, then compare that number to a flat rate. Companies that plan to double are frequently surprised.
Frequently asked questions
How much do online bookkeeping services cost?
Online bookkeeping services cost $99 to $299 per month at the entry level for cash-basis bookkeeping, and $500 to $2,000 per month for full-service accrual bookkeeping with a named bookkeeper. Adding a controller costs $2,500 to $7,000 per month, and adding fractional CFO support costs $3,000 to $12,000 per month. Most funded startups spend $300 to $1,500 per month on the bookkeeping layer alone.
Are online bookkeeping services worth it?
For cleanup projects, complex entity structures, and companies with genuinely low transaction volume, yes. The value is weaker when you need current numbers between closes or when the work you actually want is forecasting, because both of those sit outside a standard bookkeeping scope and get priced separately.
What is the difference between online bookkeeping and AI bookkeeping?
Online bookkeeping is a human team delivering a monthly close on a fixed cycle. AI bookkeeping does the categorization, reconciliation, and close work continuously, so the books are current whenever you open them. The practical difference is timing and pricing basis: a delivery cycle priced by volume versus continuous work priced flat.
Can an AI finance team replace my accountant?
It replaces the finance team, not the finance leader. Agents handle the recording, reconciliation, close, forecasting, and reporting work. Your CPA still files your taxes, and your CFO or finance leader still makes the calls. Futureproof includes a monthly review call with a human financial specialist so there is a person reviewing the work alongside you.
