Choosing the category
Bookkeeper, accountant, fractional CFO, or an outsourced finance function?
Four different jobs, routinely bought as if they were one. A bookkeeper records what happened. An accountant makes it correct, compliant and comparable. A fractional CFO decides what to do about it. An outsourced finance function runs the recurring cycle and hands you the decisions.
Choose by the problem you actually have. Too much finance work is a different problem from too little financial judgement, and the two are solved by different people.
What each model is genuinely for. And where each one stops.
These are not four grades of the same service. They own different things, they consume different amounts of your attention, and they fail in different places. The column that decides most purchases is the last one.
| Model | What it owns | What it costs you in attention | Where it stops |
|---|---|---|---|
| Bookkeeper | Recording transactions, categorising, routine reconciliation, keeping the ledger moving. | Low per task — but you carry supervision: scope, deadlines, and anything unfamiliar. | At the edge of judgement. A bookkeeper is not engaged to tell you a treatment is wrong, that the month cannot honestly be closed, or that a customer has quietly stopped paying. |
| Accountant | Correctness: classification, year-end accounts, tax computations, the position taken on unusual items. | Bursty. Heavy around year-end and deadlines, near zero in between. | At the edge of the operating month. A periodic engagement is not built to keep receivables moving or a close landing on a date. |
| Fractional CFO | Decisions: pricing, margin strategy, cash planning, funding, forecasting, what the numbers should make you do. | High, deliberately. This model only pays back if you engage with it. | At execution. A CFO works on top of finance data. Where the underlying books are late or unreliable, the engagement quietly becomes data repair at senior rates. |
| Outsourced finance function | The recurring cycle: books current, reconciliations, receivables followed up, payables prepared, payroll, close, reporting. | Low and scheduled — approvals and decisions, not chasing. | At your commercial authority, and at strategy. It runs the month. It does not set your pricing or negotiate with your lender. |
Where each one stops being enough.
Each model has a failure mode that is invisible while things are calm. These are the moments the arrangement usually stops working, described plainly rather than as a sales argument.
- A bookkeeper stops being enough when the questions outrun the records. Nobody can say why margin moved. The same reconciliation problem recurs every month. The person doing the work is the only one who understands it, and the arrangement now depends on their memory.
- An accountant alone stops being enough when you need the numbers during the year rather than after it. A year-end engagement can produce excellent statutory accounts many months after the decision you needed them for.
- A fractional CFO stops being economic when there is no reliable operating finance underneath. Paying senior judgement rates to rebuild a ledger is the most expensive way in the world to do bookkeeping, and it is a common way to spend a CFO retainer.
- An outsourced finance function stops being enough when the decision itself is the hard part — raising money, restructuring pricing, modelling entry into a new market, negotiating with a lender. Reliable execution does not substitute for that, and no provider should pretend it does.
Two different pains. Do not treat them as one.
Nearly every mis-hire in small-company finance comes from one confusion: a business with an execution problem buys judgement, or a business with a judgement problem buys hands. Both feel like progress for about a quarter.
Execution pain sounds like this:
- The month closes late, or never quite closes.
- Overdue invoices sit because nobody owns the follow-up.
- You are the escalation point for routine finance questions that are not decisions.
- The reports are accurate and arrive too late to act on.
Judgement pain sounds like this:
- The numbers are current and you still do not know which way to move.
- Pricing has not been revisited since the business changed shape.
- You are about to raise, borrow, or commit to a large fixed cost.
- Two credible options exist and the financial difference between them is not obvious.
The pairings that actually work.
Almost nobody buys one of these in isolation, and the sensible arrangements are well established.
- Bookkeeper plus a year-end accountant. The most common arrangement in small businesses, and genuinely right for many of them — modest volume, few customers on credit, an owner close enough to the money to notice a problem early. If that describes you, do not over-buy.
- Outsourced finance function plus your existing accountant. The provider runs the operating month; your accountant keeps the statutory and tax relationship. A clean split, provided the two speak to each other on a known cadence rather than through you as the messenger.
- Outsourced finance function plus a fractional CFO. The strongest combination for a business with real complexity and no finance team. Reliable numbers arrive on schedule, so senior judgement is spent on decisions instead of on assembling data.
- An in-house hire plus outsourced overflow. Sensible where the work genuinely needs someone present daily. Whether to hire at all is a separate question with its own answer: outsourced bookkeeping vs an in-house accountant.
The pairing matters more than the category. Two businesses of identical size can correctly buy completely different combinations, because their pain is in different places.
Where At Par fits — and the limits.
At Par occupies one of the four boxes: the outsourced finance function. It runs the recurring operating cycle for owner-led service businesses — books current and reconciled, evidence attached to figures, receivables followed up, payables prepared for your authorisation, payroll, the period closed on a date, and reporting delivered — with a qualified accountant (ACCA) accountable for the work.
In scope: bookkeeping and month-end close, catch-up work where the books have fallen behind, receivables and invoice follow-up, payroll, and management reporting. The full picture is on the services index.
If what you need is a competent bookkeeper and a good year-end accountant, that is a legitimate answer and usually the cheaper one. If what you need is strategic judgement on a specific decision, a fractional CFO is the right purchase and this is not it.
Asked by owners deciding what to buy.
What is the difference between a bookkeeper and an accountant? +
A bookkeeper records what happened: transactions entered, categorised and reconciled so the ledger reflects reality. An accountant is responsible for whether that record is correct and defensible — classification, year-end accounts, tax computations, and the position taken on anything unusual. The distinction that matters commercially is timing. Bookkeeping is continuous and operational; accountancy work is typically periodic and concentrated around deadlines. Many small businesses buy both, from different people, and never notice the seam until something falls between them.
Do I need an accountant if I already have a bookkeeper? +
Usually yes, because the two jobs are different. A bookkeeper keeps the record moving; someone still has to be accountable for whether the record is right, for statutory obligations, and for how unusual items are treated. In some arrangements the same provider covers both, with a qualified accountant standing behind the work. What matters is that a named party owns correctness — not that two separate invoices arrive.
What does a fractional CFO actually do? +
A fractional CFO supplies senior financial judgement part-time: pricing and margin strategy, cash planning, forecasting, funding conversations, and deciding what the numbers should make the business do. The role is advisory and directive rather than operational. It does not include keeping the books, chasing invoices or closing the month, and a CFO engagement spent on those tasks is being consumed by work it was not priced for.
When is a fractional CFO not worth it? +
When the underlying finance operation is unreliable. A CFO working on top of late or unreconciled books spends the engagement rebuilding inputs, which is the most expensive possible way to buy bookkeeping. It is also poor value where nobody has time to engage with the output: this model only pays back when someone acts on the advice. Fix the operating layer first, then buy judgement on top of numbers that can be trusted.
What is an outsourced finance function? +
An arrangement where an external provider runs the recurring finance cycle rather than performing isolated tasks: transactions recorded on a cadence, accounts reconciled, receivables followed up, payables prepared for approval, payroll processed, the period closed on an agreed date, and reporting delivered without being requested. The distinguishing feature is ownership of a rhythm. A task list can be completed while the month still fails to close; a function is judged on whether the month lands.
Can an outsourced finance function replace my accountant? +
Sometimes, and it should be explicit rather than assumed. Some providers carry qualified accountancy accountability and cover statutory work in scope; others deliberately run alongside an existing accountant who keeps the year-end and tax relationship. Both arrangements work. The failure case is ambiguity — two parties each assuming the other owns the year-end position, discovered in the week before a deadline.
Which should come first for a growing business — a bookkeeper or a CFO? +
Execution before judgement, in almost every case. Reliable records are the input to every strategic financial decision, so buying advice first tends to produce advice about figures nobody can stand behind. The exception is a single, large, time-bound decision — a fundraise, a sale, a major pricing reset — where senior judgement is worth buying immediately, with the caveat that some of the engagement will be spent assembling data.
Is a bookkeeper enough for a small service business? +
For many, yes. Where transaction volume is low enough that the owner still recognises most of it, few customers buy on credit, payroll is small or absent, and no decision is currently waiting on figures, a competent bookkeeper plus a good year-end accountant is a sound and economical arrangement. The point to revisit it is when the books stop being something produced occasionally and start being something the business relies on weekly.
