How to Spot Bar Shrinkage: Over-Pouring, Voids and Cash
Shrinkage hides in three places: the bottle, the void button and the cash drawer. Here is what to measure in each, and how often, so losses show up as numbers instead of hunches.
Shrinkage is the gap between what your bar should have made from the stock it used and what it actually made. Most owners sense it long before they can prove it. The liquor order creeps up while sales stay flat, and nobody can say where the difference went.
It almost always goes to one of three places. Each needs a different measurement.
1. The bottle: over-pouring, waste and free drinks
This is the largest leak in most bars, and most of it is not theft. It is heavy pours, spilled drinks, remakes, and the occasional drink for a friend that never reached a tab.
You find it by comparing two numbers for each product:
- Theoretical usage: what your recipes say you should have used, given everything you sold.
- Actual usage: what really left the shelf, from your counts and deliveries.
If you sold 100 drinks that each call for 1.5 ounces of a vodka, you should have used 150 ounces. If the count says 190, you have 40 ounces to explain.
Doing this by hand means a spreadsheet and a long Sunday. In Toadee it is the Inventory Variance report. Once your menu items have recipes linked to stock, it compares theoretical usage with actual usage for each stock item and flags the ones used more than expected.
One caveat that applies to any system: the comparison is only as good as your counts. Toadee marks any item without a physical count in the period as "needs count" and does not guess. Count your top ten spirits every week before you worry about the rest.
Recipes pay off a second time. With a recipe in place, an item's cost comes from current ingredient prices, so your margins update when a vendor raises a price. You find out from a report, not from a thin month.
2. The void button
A void removes a sale. That makes it the simplest way for money to disappear at the register: ring the drink, take the cash, void the tab.
Most voids are honest. Wrong orders and kitchen errors happen every shift. So the goal is not zero voids. It is a record of every one that you can read later.
Three controls do the work:
A reason on every void. In Toadee, staff choose a reason when they void a tab, such as wrong order, customer unhappy, kitchen error or employee meal, and can add notes. Every void and refund goes to a log with who did it, why, and the amount. The log cannot be edited afterwards.
Approval for the ones that matter. With Require Manager Approval to Void turned on, a void needs the PIN of someone in a role you have marked as able to approve. That can be Manager, Shift Lead, or whichever roles you choose.
A weekly look at the pattern. The Voids & Adjustments report totals voids by type, by reason and by employee. You are looking for the outlier: one person with a much larger share of voids than everyone else on the same shifts. That is a reason for a conversation, not a verdict, but it tells you where to look.
3. The cash drawer
Cash is the hardest to trace, because once it leaves the drawer there is no record at all. The control is old and it works: count in, count out, and explain the difference.
- Open each drawer with a known starting amount.
- Record every paid-out (money taken for an expense) and every drop to the safe as it happens.
- At close, count the cash and compare it with what should be there.
The result is your over/short. In Toadee the Cash Drawer page works it out as counted minus expected, and keeps a history per shift and per person.
Watch the pattern here too. A drawer that is a few dollars off in both directions is normal. A drawer that is short most nights, or short mainly on one person's shifts, is not.
Bring it together once a day
These numbers are most useful side by side. A night with high voids, a short drawer and a spirit running over its expected usage tells you far more than any one of them alone.
Toadee's Daily Close puts the day on one page: sales, payments by type, tax, comps, voided tabs and cash over/short. When you finalize it, the record is frozen and later changes cannot alter it. It is the page to hand to your bookkeeper.
A realistic routine
| How often | What to do |
|---|---|
| Every shift | Count the drawer in and out. Give a reason for every void |
| Every day | Review and finalize the Daily Close |
| Every week | Count your top-selling spirits. Read the voids report by employee |
| Every month | Full inventory count. Review variance and item margins |
None of this needs suspicion of your staff. Most of what you find will be heavy pours and honest mistakes, and both are fixed with a jigger and a conversation.
The tools described here are on Toadee's paid plans. The pricing page shows which plan includes each one. For how the plans compare on cost, see bar POS fees explained.
