Source to outcome
What should happen after you send an invoice, a receipt or a bank statement?
Six things, in order. The document is held somewhere it cannot be lost. What it is gets determined, not guessed. Its finance consequence is recorded, with the document itself attached to the entry. Whatever it commits the business to is tracked forward with a date. Anything it fails to say is raised as a question rather than filled in. And the outcome is visible to the owner without asking.
Most of those links are mechanical. One is not. The honest note nobody puts in a brochure is that the raising of missing facts is where the time actually goes — a document that cannot be understood without a fact only the business holds will sit until somebody asks for it.
One document, six links. A break in any of them surfaces later as a number you cannot defend.
A source document is a fact about the business that has happened outside it: something was bought, something was sold, money moved. On its own it is inert. The work is the chain that turns it into a position the owner can act on, and each link fails in a way you can recognise.
| Link | What has to happen | The symptom when this link is broken |
|---|---|---|
| Held | It lands in one known place, dated and referenced, and stops being a message inside somebody’s inbox. | Nobody can answer “did you get it?” without searching a thread. |
| Determined | What it is, who it is with, which period it belongs to, and how it should be treated. | A plausible entry that quietly lands in the wrong month, the wrong account or against the wrong client. |
| Recorded | The finance consequence written down, with the document held against the entry it supports. | A figure that cannot explain itself when somebody asks, six months later, where it came from. |
| Tracked | What the document commits the business to — money due, money owed, a deadline, a renewal — carried forward with a date. | The obligation is discovered by the counterparty before it is discovered internally. |
| Questioned | Anything the document does not settle raised as a specific question, to a named person, before anything is posted. | A confident guess. These are found in a clean-up, not in a review. |
| Visible | The outcome shown back: recorded, or waiting, and waiting on precisely what. | Documents go into a void and the gaps appear at month-end. |
A document does not contain its own meaning.
This is the step buyers assume is automatic, and it is the step that decides whether the books are right. Reading a document tells you what is printed on it: a date, a party, an amount, a currency, a reference. It does not tell you what the thing is.
Take one supplier invoice for a twelve-month software licence, paid up front. As a piece of text it is unambiguous. As an accounting fact it is at least four different things, and only one of them is correct for this business:
- A cost of this month, if the business does not spread costs of that size.
- A prepayment released across twelve months, if it does — which changes this month’s profit and next month’s too.
- A cost belonging to one client engagement, if it was bought to deliver a specific piece of work — which changes what that engagement actually earned.
- A rebillable disbursement, if the client agreed to carry it — in which case it is not really a cost at all, it is something you are owed.
Nothing on the face of the invoice separates those four. The separating fact lives in the engagement, the agreement, or the owner’s head. Determination is therefore a judgement made against a policy, applied the same way every month — which is also why a provider that never asks the business anything is not being efficient.
The same problem sits, in miniature, behind every card receipt. A taxi is travel — until it is a cost of delivering a specific job, at which point it belongs to that job.
The step nobody sells: the fact that is not on the page.
Capture and recording get described because they are easy to describe. Almost nobody describes what happens when a document is missing the single fact needed to treat it correctly, and that is where the genuinely slow work in a finance function lives.
These cases are ordinary, not exotic. Every business generates them every month:
- A payment arrives with a reference that matches nothing — no invoice number, no recognisable name.
- An invoice arrives with no order, no project and no indication of which piece of work it belongs to.
- A receipt is perfectly legible and the business purpose is not: a hotel in a city where you have both a client and a supplier.
- A supplier bills a round amount that could be a deposit, a stage payment or the entire job.
- A cost is shared between two engagements and only the owner knows the split.
- A contract exists, and nobody has said whether it was signed, varied, or quietly allowed to lapse.
Which is why the volume of questions a provider raises is a poor measure of quality, and the age of them is a good one. Questions are inevitable. Questions that sit for three weeks are a process failure, and questions nobody ever raised are the expensive kind.
Worth asking any provider, today: how many open questions are outstanding on our account, and how old is the oldest one?
A document is not finished when it has been recorded.
Recording settles what already happened. Most documents also create something that has not happened yet, and the back half of the chain is about not losing it.
| What arrived | What gets recorded | What it leaves open |
|---|---|---|
| A supplier invoice on 30-day terms | A cost, and an amount owed | A payment due on a date — prepared for the business to release, not released by the provider |
| A customer invoice you issued | Revenue, and an amount owed to you | A receivable to follow up, and a promise somebody should be held to |
| A bank statement | Cash movements agreed against the ledger | Every line that did not agree, each with a reason and a named owner |
| A signed engagement or renewal | Nothing at all, on its own | Billing dates, agreed scope, and a renewal or notice date that is otherwise found late |
| A payroll run | Wages, deductions and employer costs | Statutory amounts and deadlines, identified and prepared ahead of the date |
The last link is the one that makes every other link checkable. Ask what happened to something you sent, and there are only three acceptable answers: it is recorded, it is waiting on one specific named thing, or it was rejected for a stated reason. Anything vaguer than that is a filing cabinet with good manners.
Six questions that test the chain rather than the pitch.
Each of these lands on a specific link. A provider that runs the chain answers them in a sentence; a provider that performs tasks answers them with a description of software.
- Held. Where does a document go once it is sent, and how would I find it in a year?
- Determined. Who decides how an unusual cost is treated, and against what — a policy, or whoever picks it up?
- Recorded. If I open one figure in the accounts, can I get to the document behind it without emailing anyone?
- Tracked. What did last month’s documents leave open, and where does that list live?
- Questioned. How many questions are outstanding on us, how old is the oldest, and who is holding each one?
- Visible. Without asking, how would I know something I sent was never recorded?
The fifth question is the one that separates providers. Everything else can be answered by describing a system. That one can only be answered by looking at the account.
Where At Par fits — and the limits.
At Par runs this chain as a service for owner-led service businesses. Documents arrive however they are easiest to send. They are held, determined against a treatment that stays consistent month to month, recorded with the evidence attached, and whatever they leave open is carried forward with a date. Where a fact is missing, you get a specific question rather than a confident entry — and a qualified accountant (ACCA) is accountable for the work.
That chain feeds the rest of it: bookkeeping and month-end close, receivables and invoice follow-up, payroll, and monthly management reporting. If documents have been piling up for months rather than days, that is catch-up work first, then the chain. Where documents and evidence are kept, and who can reach them, is set out under security.
Curious what the chain looks like on your own paperwork rather than in the abstract? Send one document and see what comes back. For the wider question of which finance outcomes a provider should own at all, see what an outsourced accounting provider should actually own.
Asked by owners who have just sent something and heard nothing.
What does an accountant actually do with the invoices and receipts you send? +
Six things. The document is stored somewhere durable and referenced. Its meaning is determined — what it is, whose it is, which period it belongs to, and how it should be treated. The finance consequence is recorded with the document attached as evidence. Any forward obligation it creates, such as a payment date or a renewal, is tracked. Anything the document does not make clear is raised as a question. And the outcome is made visible without the sender having to chase it.
What is a source document in bookkeeping? +
A source document is the original record of something that happened outside the books: a sales invoice, a supplier bill, a receipt, a bank statement, a contract, a payroll report. It is the evidence a figure rests on. Books built without source documents attached are assertions rather than records, and the difference becomes visible the moment somebody — an owner, an auditor, a lender or a buyer — asks where a number came from.
How long should it take before a document that has been sent is recorded? +
The honest answer is that it depends on whether the document is self-explanatory. A complete, unambiguous document should be recorded on the provider’s normal cycle, which for most owner-led businesses means days rather than weeks. A document that needs a fact only the business holds cannot be recorded until that fact arrives, and should sit visibly as an open question with a named owner rather than being quietly guessed at.
Why does a bookkeeper ask so many questions about ordinary expenses? +
Because the same document can be several different accounting facts, and the deciding detail is rarely printed on it. A round supplier payment might be a deposit or the whole job. A hotel bill might be a cost of delivering a client project or general travel. The alternative to asking is guessing, and a guess looks identical to a correct entry until somebody tries to rely on it. Fewer questions is not the same as better work.
Do documents need to be sorted or categorised before sending them to an accountant? +
No. Sorting is the provider’s job, and a business that categorises its own paperwork is doing the work twice while introducing a second opinion into the books. What genuinely helps is context that is not on the document itself: which client or project a cost belongs to, whether a payment is a deposit or a final settlement, and whether an unusual item is a one-off. Send the document as it is; supply the context when asked.
What happens to a receipt sent with no explanation attached? +
If the treatment is obvious from the document, it is recorded. If it is not, it should be held as an open item with a specific question against it, rather than posted to a general catch-all account. Catch-all coding is the quiet failure mode here: the amount is in the books, the total looks complete, and the underlying detail is gone. Recorded-with-a-guess and recorded-correctly are indistinguishable on a report.
How should a business send documents to its accountant? +
Through one channel, consistently, so that receipt is provable. Whether that is email, a shared folder or an upload matters far less than whether everything goes to the same place. Documents scattered across personal messages, phone photos and a director’s inbox will eventually produce a month that cannot be closed, and the reconstruction costs more than the original sending would have. One route, used every time, is the whole discipline.
What does it mean when an accountant says an item is on hold? +
It should mean the item cannot be treated correctly until a specific fact arrives, and that the fact has been named. A held item is a working state, not a failure — it is the visible alternative to a guess. What matters is that it carries a reason a non-accountant can read, a named owner, and a date, and that the total of held items is shown to the business rather than kept internally until month-end.
