Drink Commission for Bar Staff
How to Calculate It Without Month-End Arguments

A bar is different from a restaurant in one key way: the person selling directly affects the sales. A staff member who is good at upselling brings in many times more than someone who just waits to take orders. That is why drink commission is the main motivation tool in this business.

But when it comes time to actually pay out, it turns into the thing people argue about the most.

Why working out commission by hand always breaks down

The method most shops use is to have staff write their own name on the slip, or have the cashier note which table each person is looking after, then add it all up at the end of the month.

• Slips get lost or can't be read — bars work in the dark and the noise, and handwriting on a wet slip that you can't make out is completely normal.
• Tables change hands during the night — staff swap shifts or help each other serve, and by month-end no one can say who should get the commission for that table.
• Staff keep their own tally too — and the numbers don't match the shop's, which happens almost every month.
• Closing the period takes forever — many owners lose two or three days a month just adding up slips.

How an order-to-staff system works

Tie it to the line item, not to the table

The thing that makes the system work in practice is tying commission at the line-item level in the bill, not to the whole table — because a single table may be served by several staff throughout the night.

When a staff member rings a drink into the system, it records who entered that item. At close, the commission goes to whoever actually sold it, even if that table was looked after by several people.

The commission rates you should be able to set

Every shop calculates it differently. A flexible system should support at least three models.

Staff must be able to see their own totals

This is what separates a system that reduces the problem from one that just moves it. If staff can see their running commission total during the month, there are no arguments at month-end — because if a number is wrong, they'll flag it that same day, not at payout time when it is already hard to trace back.

All-night tab bills — where sales quietly disappear

Almost no bar closes a bill for every round. Customers keep ordering all night and pay once when they leave. Systems designed for made-to-order restaurants often handle this poorly.

What the system has to be able to do:

• Add unlimited items to the same bill without having to close it and open a new one.
• Move tables — the customer moves from the bar to the sofa, and the bill has to follow.
• Merge and split bills — two tables who know each other want to pay together, or one group wants to split the payment.
• An open-bill report before closing up — so the manager can scan for any table where the customers have already left but the bill is still open.

That last point matters more than you'd think. A bill left open overnight is revenue that quietly disappears, and usually no one notices until the monthly close.

Staff drinks — don't mix them into sales

Almost every bar has a policy that lets staff drink, whether as a perk or when a customer treats them. The problem is that many shops record it together with normal sales, which throws the numbers off in two ways.

• Gross profit looks better than it really is, because there are items in there that never actually brought in money.
• Staff commission is distorted if the staff drinks get counted as someone's sales.

The right way is to record it as a separate item type that deducts real stock but doesn't count as sales. That way the owner sees this cost clearly and can set a monthly cap per person if they want.

A checklist before choosing a bar POS

1. Can you tie each line item in the bill to the staff member who rang it in (not to the whole table)?
2. Can you set commission rates separately by product group?
3. Can staff open and view their own running commission total?
4. Can you keep a bill open all night, then move tables, merge bills and split bills — all of it?
5. Can you record staff drinks so they deduct stock but don't count as sales?
6. Is there a report of still-open bills to review before closing up?
7. If you unplug the internet, can you still open bills and take payments?

In summary

A good commission system doesn't just save you time at close — it protects the trust between the shop and its staff, which is the asset a night business needs most and finds hardest to rebuild.

The principles are: tie it to the item, not the table · let staff see their own totals · keep staff drinks out of sales. Those three already fix most of what goes wrong at a bar.
