Key takeaways
- Every complete entry records at least two effects of one business event.
- Debit or credit has no standalone meaning; the account type determines the effect.
- Invoice and payment are often separate entries and must not be counted twice.
- Final account and tax-code selection belongs in professional review.
Start with the event, not the side
Suppose a business receives a supplier invoice for €1,000.00 and pays it ten days later. Two things happen at different times: first an obligation is recorded; later cash leaves and the obligation is settled. If someone starts only with the bank debit, they may miss the earlier invoice or record the expense twice.
A better sequence is:
- identify the business event;
- identify the affected resources, obligations, revenue, or expense;
- confirm the supporting evidence and date;
- then review which side of which account carries each effect.
“Debit” and “credit” are positions in that structure. They do not tell the whole story without the account name.
A small orientation table
The following is conceptual, not a chart-of-accounts prescription:
| Account family | Increase commonly appears on | Decrease commonly appears on |
|---|---|---|
| Assets, such as bank or receivables | Debit | Credit |
| Liabilities, such as supplier payables or loans | Credit | Debit |
| Revenue | Credit | Debit or correction side |
| Expenses | Debit | Credit or correction side |
| Equity | Credit | Debit |
This explains why a bank statement’s “credit” or “debit” label can confuse people. Bank statements may describe the bank’s perspective or simply money in/out. Accounting entries describe effects across the business’s accounts. Always read the account and business event together.
Worked example: invoice first, payment later
A synthetic business receives a €1,000.00 supplier invoice for a current service. Ignoring VAT and any period adjustments, the simplified logic is:
| Moment | Effect 1 | Effect 2 |
|---|---|---|
| Invoice is recognised | Expense increases | Supplier liability increases |
| Invoice is paid | Supplier liability decreases | Bank asset decreases |
The payment does not create the same expense again. It settles the obligation created by the invoice. That is why document-to-payment matching matters: it connects two stages of one event.
Now consider a sales invoice. The simplified pattern is different:
| Moment | Effect 1 | Effect 2 |
|---|---|---|
| Sales invoice is recognised | Customer receivable increases | Revenue increases |
| Customer pays | Bank asset increases | Customer receivable decreases |
Again, the cash receipt is not automatically new revenue. It may settle an existing receivable.
A platform balance movement
A payout file can contain a €500 reserve released from a balance created in an earlier period. The bank receives €500 now, but the payout row is not automatically new revenue. In a simplified orientation, cash increases while the carried platform receivable/balance decreases. The original sales or withholding event belongs to the earlier source chain.
This is why a prepared payout cannot be read as “debit means cost, credit means revenue”. First ask whether the row represents current activity, settlement of an open position, or movement of an existing balance.
These examples omit VAT, corrections, cash-basis differences, and other facts. They explain double-entry orientation only. The responsible accountant must approve the real accounts and treatment.
Four questions for reading a proposal
When a posting proposal shows debit and credit lines, ask:
- Which business event does the proposal represent?
- Which document and payment support it?
- Which account is increasing or decreasing on each line?
- Is the proposal recording the invoice, the payment, a correction, or a combination?
Then check amount, currency, date, counterparty, and tax context. A balanced entry can still be wrong if it uses the wrong source, period, account, or tax treatment. Mathematical balance is necessary, not sufficient.
For an owner reviewing a DeinHans proposal, the useful questions are practical:
- Does the source belong to my business and describe what actually happened?
- Is this proposal recording the invoice, the later payment, or a carried balance movement?
- Is any amount duplicated because the bank row and source document were treated as separate events?
- Is a missing business fact being asked from the right person?
The owner can correct those facts without choosing an account or tax key. DeinHans prepares the evidence-linked structure; the accountant decides or approves the professional treatment.
Categories are not accounts
An owner-facing category such as “Software” can help organise documents and search results. It does not automatically determine the final posting account. Two software invoices can differ because one is a current subscription, another relates to a longer period, one comes from abroad, or one includes a correction.
Software can use categories and evidence to prepare a proposal. The accountant should see the source and the proposed effects before approving or changing it. An unexplained system shortcut or score should never replace that visible review.
Who should decide what
| Task | Owner | Software | Accountant |
|---|---|---|---|
| Explain the purchase or sale | Provides the business fact | Keeps the answer with the item | Checks whether the fact is sufficient |
| Connect invoice and payment | Confirms unusual differences | Suggests and displays links | Reviews material or ambiguous settlement |
| Prepare debit/credit lines | Does not need to memorise accounts | Can prepare a proposal | Selects or approves accounts and tax treatment |
| Correct an error | Explains new facts | Preserves the earlier state and change | Chooses the professional correction route |
DeinHans can prepare evidence-linked booking proposals for review. A proposal remains review material; it is not a final professional decision merely because both sides balance.
A useful mental shortcut
Do not ask “Is debit positive?” Ask “Which account changed, in which direction, because of which event?” That question works for invoices, payments, loans, transfers, refunds, and corrections. It also reveals when a proposal is missing a second stage, such as an open invoice that was paid but never settled.
The aim is not to become an accountant from one article. It is to read the structure well enough to spot double counting, ask for the source, and leave account selection with the person responsible for it.
