The report says 7,207 and the drawer says 7,000.

Three things to rule out first

In most shops the difference turns out not to be a difference at all, and three checks take about a minute between them.

• The report is not one drawer It shows every till, every bank account and the petty cash box — everything your chart maps as somewhere money sits. A shop with four counters reading one figure is reading all four. Open the breakdown: each till is a line of its own.
• The report is not only notes A bank line is money in a bank. If you are holding a drawer in your hand, you are comparing it against one row, not against the total.
• Today may not be finished A sale is in the report the moment it is rung up. If the shift is still open, the report is ahead of the count by whatever has been sold since you last looked.

What the report can know, and what it cannot

The cash figure is not a separate calculation living off on its own — it is your own books, read through a filter that keeps only the accounts you mapped as money you can spend. It agrees with your trial balance by construction, because it is the same figure.

That is also the limit of it. It knows every sale, refund and payment that was recorded. It cannot know about a sale nobody entered, or a note taken out of the drawer for a taxi, or change handed over wrongly. Only a count knows that — which is why counting is not a formality, and why a shop that never counts has a cash figure nobody has ever checked.

Where to look for the moment they parted

If the difference is real, each line of the cash report opens its own statement: every movement in and out of that particular till, in order, with a running balance beside it. That running balance is the thing to read. Scroll back until it last agreed with what you know you had, and the entry after that is where to start asking.

A till that has been counted every night makes this a one-day search. A till counted once a month makes it a month-long one — which is the practical argument for the nightly count, more than any principle about it.

Two figures that look wrong and are not

A bank line showing a negative amount is an overdraft, and it is shown as a negative rather than hidden. It is the truth about where the money is, and a report that quietly dropped it would be flattering you about the one number you cannot afford to be flattered about.

A fund showing zero with the words no movement this year is an account you mapped and have not used. It is deliberately still on the page: an account with nothing in it and an account missing from the report look identical to somebody counting their money, and only one of them is safe to conclude.

What the product does not do yet

You cannot ask this report for one branch. Every till and bank account is recorded as a party rather than as belonging to a shop, so a business with several branches reads one organisation-wide figure and then the per-till breakdown underneath it. In practice the breakdown answers the question — you know which tills are in which shop — but there is no per-branch total, and there will not be one until tills know where they live.

And every report says which figures it was built on

Where a report can be drawn two legitimate ways, it prints which one it used, on the page and on the printout. The financial statements do this with the value of your stock: it can be taken from the shelf, live, or from the books, which is right once the month is closed. Neither is wrong and they are not the same, so the statement names the one it used rather than leaving you to guess.

It is the same habit as the cash figure. A number is only useful if you know what it counted.
