One shift tells you nothing. The pattern does, the same name short on the same nights. Bar Cop tracks it by shift and by person.

What Good Looks Like

How much over/short is normal.

A drawer never lands perfect every time, and chasing every nickel will drive you and your staff crazy. What matters is the size and the pattern. These are the lines operators watch. They are guides, not laws, and every bar sets its own tolerance.

Over or shortWhat it usually means
Under $2, or under 1% of cash salesNormal counting noise, let it go
Short 1% to 2%, now and thenMiscounts, missed paid outs, sloppy change
Short past 2%, or the same person every timeWorth a real look
Over on the regularUnder-ringing or wrong change, not free money
The thing to watchThe pattern, not the one-off

A single short is a bad night. The same short, on the same shift, under the same name, is a signal. The only way to tell them apart is to reconcile every drawer and tag it to a person, week after week. Bar Cop does that quietly in the background, so when a real pattern shows up you can find out who instead of guessing.

The Math

How over/short is calculated.

Step One

What should be there

Start with the bank you opened with, add the cash sales the register rang, and subtract any paid outs, the cash that left the drawer for a tip-out, petty cash, or a refund. That is what should be sitting in the drawer at close.

Step Two

What is there

Count it. Every bill and every coin in the drawer. Do it the same way every time so the count itself is not the thing throwing your number off. Then set the bank aside, and the rest is what you drop or deposit at the end of the night.

Step Three

Subtract

Over or short is counted minus expected. More than expected is over, less is short. A dollar or two either way on a busy night is noise. A real number is one that keeps showing up, and over is a problem too, it usually means under-ringing, not free money.

Straight Answers

The cash drawer questions.

What operators ask when the drawer and the register do not agree.

How do you calculate cash over or short?
Take your starting bank, add cash sales, subtract any paid outs, and that is what should be in the drawer. Count what is actually there. Counted minus expected is your over or short. A positive number is over, a negative number is short.
How much cash over or short is normal?
Under a dollar or two, or under about one percent of cash sales, is normal counting noise on a busy shift. One to two percent now and then usually means miscounts, missed paid outs, or sloppy change. Past two percent, or the same person short every shift, is worth a real look.
Is a cash drawer being over a good thing?
No. Over is still an error, it just runs the other way. It usually means under-ringing, wrong change given back, or a missed paid out. Money you cannot explain is a problem whichever direction it points, because it means the drawer and the register do not agree.
How do I find out who is short?
One shift tells you nothing. You find it in the pattern: reconcile every shift, tag each one to the person who ran the drawer, and watch over time. A random short moves around. A real one has a name on it, the same bartender coming up short on the same nights.
What causes most drawer shortages?
Miscounts and wrong change, first and most often. Then a paid out that never got logged, a sale rung on the wrong tender, and a starting bank that was never verified. Theft is real, but it is the last thing to look at, not the first.
Should each bartender have their own bank?
Yes, if you ever want to know who is short. A drawer three people touched cannot be tied to anyone, so every shortage becomes nobody's. One person to one drawer for one shift is what turns a number into a name.
Do paid outs come out of the drawer count?
They come out of what you expected, not out of what you counted. A paid out is cash that left the drawer for a real reason, so it lowers what should be there. Count the drawer as it sits and let the expected figure carry the paid outs.
Should credit card tips be in the drawer?
No. Card tips are paid through payroll or a tip-out, so they never belong in the cash count. Mixing them in is one of the most common reasons a drawer reads short by almost exactly the tip total.
What is a blind drop and should I use one?
A blind drop means the person counting does not see what the register expected. It is the single cheapest control here, because somebody who can see the target can count to it. Every serious cash process is blind for that one reason.
How long should I keep drawer counts?
Long enough to see a pattern, which means months and not days. One short drawer is noise. The same person short on six of eight shifts is a finding, and you can only ever see that in the history.
