Rules
Part of Every expense answers three questions: when, where, and whose
Expense recording framework: signal versus noise, 2027 edition
An expense recording framework of five gates every outgoing payment passes: what kind of thing, which period, which line, whose it is, and what proves it.
What to take away
- Gate one asks what kind of thing the payment is, not which account. Five of its six answers are not a cost.
- Gate two sets the period from the supplier's document, not the bank statement date.
- Gate three draws the margin line, then picks the account from written definitions.
- Gate four names whose cost it is and records the split basis at entry.
- Gate five attaches the supplier document. A bank feed line proves only that money moved.
Gate one: six answers before any account
Take the six in order. Earlier answers rule out later ones, and the last few are where mistakes hide.
Gate One: What Kind of Thing?
Is it a movement between your own accounts?
Transfer account, nets to zero
Is it settlement of something already recorded?
Gate one: six answers
| Answer | Test | Where it lands |
|---|---|---|
| Cost | Used up in the ordinary course, nothing lasting remains | Expense for the period |
| Asset | Keeps value past the current year | Balance sheet, written down over its life |
| Loan principal | Settles a debt you owe | Liability, split by the lender schedule |
| Deposit or prepayment | Paid ahead for goods not yet received | Prepaid asset, released as used |
| Owner drawing | Serves the owner personally | Drawings or owner equity |
| Third-party money | Held or passed on for someone else | Liability, such as sales tax collected |
The asset answer follows rules, not preference. Depreciation, Section 179 and bonus depreciation sit in IRS Publication 946. The index of deductible business costs is the IRS guide to business expense resources.
Landing places are accounts, defined once and written down. The chart of accounts framework shows how each definition is derived from the statements the owner already reads.
Record the rule you applied and the date you checked it. One payment getting two answers in two months means a thin description or a missing document.
Gate two: the period the value was used
Only a cost reaches this gate. The question is when the value was consumed.
Gate two: the period
- Consumed now. Post the cost in the period of use. The supplier invoice date and description set that period.
- Consumed later. Pay now, use later. Hold it as a prepaid asset and release it to expense as the value is used.
- Consumed already. The value arrived before the invoice. Accrue the cost in the period of use and clear the accrual when the bill lands.
The supplier document decides the period. The bank statement carries noise, since it shows only that money left. The document carries the signal, which is what was bought and when it was used.
Gate three: above or below the margin line
Ask whether the cost moves with what you sell. Materials, subcontractors on jobs, delivery out and job labor rise and fall with volume, so they sit above the gross margin line.
Rent, insurance, administrative salaries and software carry on whether you sold anything, so they sit below it. Set that boundary once and hold it. A boundary that moves makes comparison across periods meaningless.
Inside the chosen half, the written definition picks the account. Gates two, three and four ask when, where and whose, and the expense recording guide works through all three. Where nothing fits, park the entry in a holding account with the document attached.
Gate four: business, owner or third party
Every cost belongs to the business, to the owner as drawings, or to a third party whose money you are holding. Decide at entry. A year later the split cannot be rebuilt without guessing.
Where a cost is shared, the business share is a cost and the rest is drawings or an owner balance. Record the basis and the date beside the entry. A vehicle used 70 percent for business carries 70 percent of its running cost, and the note says how that share was measured.
Gate five: the proof that makes it checkable
Gate five: the proof
- The supplier's own document, with name, date, amount and what was bought.
- A mileage log written at the time of the trip, with date, destination, purpose and miles.
- The written basis for any cost shared with the owner.
- The lender's schedule behind any loan payment.
A card statement, a bank feed line or a payment screenshot proves that money moved. Money moving was never in doubt. None of them shows what was bought, for whom, or whether the cost is deductible. That standard sits in the federal guidance on records a business keeps.
Most proof problems start upstream, when a document arrives and sits unmatched. The six stage accounts payable pipeline treats arrival, approval and reconciliation as separate steps.
Example: two payments split into coded lines
An invoice for 1,000 covers 600 of materials used on a job, 200 of courier charges delivering that job, 150 of workshop consumables and 50 of office stationery. Gate one calls all of it a cost. Gate three sends the first three items to cost of sales and the last to office expense.
One Invoice, Four Facts
- 600Materials used on a job
- 200Courier charges delivering that job
- 150Workshop consumables
- 50Office stationery
Coded as one line to the supplier's usual account, all four facts vanish and the margin on that job goes with them.
A 1,000 loan payment whose lender schedule shows 820 principal and 180 interest becomes two entries: 820 against the loan liability, 180 to interest expense. The schedule is the only thing that separates them, since the bank shows a single line.
Code the whole 1,000 to interest and the loan balance never falls, while profit is understated by 820.
Several of these patterns are traced entry by entry in six situations worked through to the postings.
