What each one actually does, the order to hire them in, and the parts you should never hand over however big you get.
11 min read · Level 3
Hand over the work, never the understanding. A founder who cannot read their own P&L has not delegated finance, they have delegated knowing whether the company is alive — and they will find out it was delegated at the worst possible moment. The right sequence is always: learn it, do it, systematise it, then hire it. Skipping to the last step buys time and costs judgement, and judgement is the thing the job actually requires.
Four distinct roles, usually acquired in this order:
Bookkeeper — records transactions, reconciles, keeps the ledger clean. Hourly or monthly retainer. Accountant — statements, filings, tax, structural advice. Usually annual plus ad hoc. Fractional CFO — model, board pack, fundraising preparation. A few days a month. Full-time CFO — owns finance as a strategic function. Series B and beyond for most companies.
Because founders get this sequence wrong in both directions. Some do their own books for four years and lose weeks a year to work worth a fraction of their time. Others hire a full-time finance lead at twelve people and pay six figures for a job a retainer would cover.
And because the handover point is not about size, it is about whether the work has become routine. Routine work is safe to hand over. Judgement is not.

A reasonable progression:
Months 0–12, pre-revenue to early. Do it yourself. Fifteen minutes weekly, two-hour monthly close. You will learn more about your company than any report would tell you. Get an accountant before your first filing.
Around £20–50k/month of spending, or 30+ transactions a month. Hire a bookkeeper — a few hundred a month. You keep the close and the interpretation; they do the recording. This is the highest-value handover and founders delay it for years.
First priced round, or the first board. Fractional CFO, two days a month. They own the model and the board pack; you still own the narrative and the decisions.
Series B, or 50+ people, or complex revenue. Full-time CFO.
Never hand over: knowing your six numbers, the decision about what to cut, or the story your reports tell. Those are the job.
First-time founders hire a bookkeeper and stop reading the reports. The whole benefit was supposed to be time to think about the numbers, and the time gets spent elsewhere while understanding quietly decays.
The second mistake: hiring a full-time finance person too early because a board member suggested it. An accountant on retainer plus good software covers what a twenty-person company needs, at a tenth of the cost.
The third: assuming the bookkeeper's categorisation is right. They do not know your business; they will put contractor costs wherever looks reasonable. Review the categories monthly — that is now your job, and it takes ten minutes.
At least six months. You are buying understanding, and there is no other way to acquire it.
A bookkeeper takes the mechanical half. Keep the close, the review and the commentary.
Not after. They will tell you what to record now so the filing is straightforward later.
Option grants and share issues carry tax consequences for you and your team, and the rules vary by jurisdiction.
Ten minutes. Your bookkeeper does not know which contractor was building product and which was delivering to a customer.
Usually later than it feels. Fractional covers the model, the board pack and a raise for a fraction of the cost.
Revisit at each stage change — first revenue, first round, first board, first fifty people.
Do not hand off while the books are still a mess. You will pay someone to inherit a problem they cannot see, and get a clean-looking ledger built on the same wrong categories.
Sahil Lavingia has written publicly and in detail about Gumroad's history, including the decision to shrink the company dramatically after growth stalled and a planned round did not materialise. The account is unusually specific about the numbers and about how long it took to accept what they were saying.
The numbers usually say it before the founder is ready to hear it. Reading your own reports monthly shortens the gap between the two — which is the only part of that story you control.
The recognisable pattern is not hiring a bookkeeper too early or too late. It is hiring one and quietly stopping the monthly review, so that six months on the founder is fluent about product and vague about margin — and the vagueness only becomes visible in a fundraising conversation, in front of the person it matters most to.
When you hire the recording out, put the review in your calendar the same week. The handover is meant to buy thinking time, not remove the obligation to think.
