We are building Scouq in the open, and part of that is showing the actual mechanics. This is one of the thirteen checks that every month has to pass before it closes — and it exists because the mistake it catches is one of the most common in small-business books.
How spending gets counted twice
Say you put $3,000 of materials on the business credit card in March, then pay the card off from checking in April. Two bank feeds see that story:
- The card feed shows $3,000 of purchases — real expenses, correctly categorized.
- The checking feed shows a $3,000 payment going out to the card company.
If that card payment gets categorized as an expense — and left to auto-categorization, it often does, because it looks like any other outflow — the books now show $6,000 of spending that was really $3,000. Profit looks worse than it is. Decisions get made on the wrong number. And if it happens every month, the distortion compounds quietly all year.
The check
The fix is mechanical, which is exactly why it makes a good automated check. A card payment is not an expense — it is a transfer: money moving between two accounts you own. And a transfer always has two ends. So every month, the check walks every transaction flagged as a transfer and asks one question: where is the other side?
- A payment out of checking must pair with a payment received on a card or loan account, same amount, close dates.
- Anything that looks like a card payment but sits in an expense category gets flagged.
- Anything categorized as a transfer with no matching other side gets flagged too — that one is often a missed real expense, the same mistake in reverse.
A person reviews the flags — some have honest explanations, like a payment crossing a statement boundary — and the month cannot close while any flag is unresolved. That last part is the point. The check is not a report someone might read. It is a gate.
Why we are writing this down
Every bookkeeping service says it is accurate. We would rather show the mechanism than use the adjective. If you want to see where your own books stand on this and seven other fronts, the free books check takes about two minutes.
