Best POS for a bar that runs tabs
A bar POS lives or dies on tabs: open one from a card in a few seconds, keep it open across three bartenders and a shift change, and close it with a tip without the guest's card in hand. Here is how the main systems handle that in 2026, and what else to test before you buy.
Why pre-authorization matters more than any other feature
A pre-authorization puts a temporary hold on the guest's card when the tab opens. If the guest walks, you can still close the tab to the saved card. Without it, you either hold the physical card behind the bar (lost cards, mix-ups, guests who leave without it) or you eat the walkout.
One $70 walkout a week is $3,640 a year, before the drinks that were never rung in because the bartender was busy chasing the last one. That alone pays for the difference between a cheap POS and a good one.
The details that matter in the demo:
- Hold amount. Can you set it, and does the hold grow as the tab grows?
- Card entry. Tap, dip or swipe? Some systems need a dip or swipe to capture the cardholder's name for the tab.
- Closing. Can a different bartender, on a different terminal, close it with a tip? Does it close itself at end of day?
- Decline at close. What happens when the tab is bigger than the hold and the card declines at close-out?
- Offline. Does pre-auth keep working when the internet drops? (Usually not.)
How each system handles tabs
| System | Pre-authorized tabs | Hold amount | Card entry | Notes |
|---|---|---|---|---|
| Toast | Yes | Set a minimum; hold is the minimum or the check total, whichever is higher | Dip, tap or swipe on single readers; swipe only on dual-reader setups | Holds last 24 hours; one card per check; close manually; not in offline mode |
| Square for Restaurants | Yes, since Dec 2024 | Set in the app | Card or digital wallet | Confirm details on your hardware in the demo; the feature is new |
| Lightspeed Restaurant | Yes, with Lightspeed Payments | Default amount you can change per tab | Insert or swipe; a tap does not capture the name | US, UK and Australia only |
| SpotOn | Yes | You set it; incremental authorization available | Chip insert preferred; it pulls the cardholder name | Closing records the card tip and signature |
| Aloha (NCR Voyix) | Yes | Configurable | Any | Mature; works with the local server offline |
| Clover | Through apps | Depends on app | Depends on app | Check the specific tab app before you commit |
Toast
Toast's pre-authorization is set in the back end under payment options, with a minimum amount you choose (a typical minimum is the price of one drink; Toast will not allow $0). The hold is the minimum or the check total, whichever is higher, and it lasts 24 hours. One card per check, and the check closes manually to the saved card, on any terminal, in Shift Review before the shift ends.
Two things to know. First, if you run a guest-facing display with two readers, pre-auth needs a swipe on the magnetic stripe reader; to use tap you remove that reader. Second, Toast voids the hold immediately after closing, so guests sometimes see a pending hold next to the final charge for a day or two, and a few banks take five or more days to clear it. Train bartenders to explain that in one sentence.
Beyond tabs, Toast gives you handheld ordering, tab transfer between servers, split by seat, and happy hour pricing by time. It requires Toast Payments and a 24 or 36 month term.
Square for Restaurants
For years the honest answer was "Square does not do pre-authorized tabs." That changed on December 18, 2024, when Square shipped pre-authorization for Bar Tabs with credit cards and digital wallets. Before that you could open a tab by swiping a card, but the card was not held.
Square still fits small bars and taprooms best: no contract, hardware you buy outright, and the Free plan if you accept a higher processing rate. Verify the pre-auth hold settings on your exact hardware in the demo, because the feature is new and the documentation is thin.
Lightspeed Restaurant
Lightspeed opens a tab with a default pre-authorization amount you can change before confirming, and closes it to the saved card or to another payment method. It needs Lightspeed Payments and a card insert or swipe (a tap will not capture the cardholder's name for the tab). It fits hotel bars and venues with several revenue centers, and it runs on iPads.
SpotOn
SpotOn markets pre-authorization hard, and its workflow is sound: you set the hold, chip insert pulls the cardholder name onto the tab, and close-out records the card tip and signature. It also mentions incremental authorization, which raises the hold as the tab grows. SpotOn publishes two plans ($0 All-In at 2.79% + $0.20, $55 per station Essentials at 2.45% + $0.15) and quotes larger accounts; get the fee schedule in writing either way.
Aloha
If you are already on Aloha, tabs are not your problem. Pre-authorization, transfers and splits have worked the same way for decades, and the local server keeps tabs open when the internet is down. The reasons bars leave Aloha are contracts, hardware refresh costs and slow feature changes. See the Aloha alternatives comparison if that is where you are.
The rest of the bar checklist
Pre-auth gets the headline, but these decide whether bartenders like the system by week two:
- Speed to open. Card in, tab named, first drink rung, in under five seconds. Time it.
- Transfer and merge. Move a tab from the bar to a table, merge two tabs, split by seat, with no manager code.
- Repeat round. One tap to ring the last round again.
- Price levels. Happy hour, late night and event pricing that switch on by time without a manager.
- Age check prompts. Optional, but a prompt on the first alcohol item protects your license.
- Cash drawer per bartender. Shared drawers end in arguments.
- Tip handling. Card tips by bartender, pooled by shift. Use the tip pool calculator to check the split your POS reports.
- Inventory hooks. Depletion by pour so the pour cost and keg yield numbers you plan with match what you sell.
Taprooms and breweries
A taproom rings fast, pours many sizes of the same item, sells merch and crowlers, and often runs a members club. Square works well here at small scale, and Toast at larger scale. Arryved, a POS built for breweries, is worth a look if flights, pour sizes and membership are most of your volume. Whatever you choose, test a flight of four 5 oz pours and a 64 oz crowler on the same keg item, and make sure the keg yield math survives.
