The right bar POS is the one your staff can use to open, find, transfer, and close a tab during a busy shift—with a payment workflow you understand and can afford. Ask each vendor to demonstrate those steps using the same order. A long feature list is less useful than seeing what happens when a bartender leaves mid-tab or a guest wants to split a check.
Start with your service pattern. A neighborhood bar with regulars who keep tabs open has different needs from a venue that takes payment for every round. Both need fast order entry, but the tab-heavy bar should pay particular attention to card authorization, handovers, and unresolved checks.
Set your bar’s requirements before comparing systems
Walk through a busy shift with a bartender and a manager. Note where orders are taken, where drinks are prepared, and who closes checks. A restaurant POS system should fit that route through service, rather than require staff to walk around the bar or share a single login to complete routine tasks.
Write down the answers to these questions:
- Do guests usually pay per round, run a tab, or move between the bar and a dining area?
- How many staff need to enter orders and take payments at the same time? Where will each device sit?
- Which drink choices affect price, such as a premium spirit, a double, or an added mixer?
- Who may transfer a tab, remove an item, apply a discount, or close another employee’s check?
- What must the closing manager see before staff leave: open tabs, payment status, adjustments, or all three?
Separate must-haves from preferences. For example, if bartenders routinely hand active tabs to the next shift, a clear transfer process may be essential. A preferred receipt layout can come later. Give vendors your must-have list before the demo so they can show the actual workflow, including any additional equipment or services it requires.
Follow one tab from first drink to close
The most useful bar POS system features work together. Ask the vendor to show the screen a bartender uses at each step, not just describe the feature. Count the decisions and handoffs your staff must make; a workflow can technically exist and still be awkward at a crowded bar.
Open and identify the tab
Show how an employee starts a tab and finds it again when several guests have similar names. Ask what identifiers are visible, whether the identifier can be changed, and how staff avoid adding drinks to the wrong check. Decide what information your team actually needs; collecting more guest information than staff can manage is not a substitute for a clear lookup process.
If you want to authorize a card when a tab opens, ask the vendor to distinguish an authorization from the final payment. Find out how the authorization amount is set, what staff see if it is declined, and what happens if the final check exceeds it. Also ask whether the card must be presented again to close. The answer may depend on the payment setup, so get it in writing for the equipment and processor you are being quoted.
Add drinks and correct mistakes
Use your own menu language. Have the vendor enter a drink with a priced spirit upgrade and another with a preparation choice. Check that the item, modifier, quantity, and price are visible before the order is sent. Then change an item and ask how the bartender can see that the correction took effect.
Ask who can void a drink or adjust a price, whether approval is needed, and where a manager can review the action later. The goal is not to prevent every correction. It is to let staff fix an honest mistake without making the check impossible to explain at close.
Hand over and settle the check
Have one simulated employee start the tab and another take responsibility for it. Can the second person find the order, see its current balance and payment status, add a round, and close it without sharing credentials? Ask what happens to attribution and tips when responsibility changes. Your house rules should determine whether the demonstrated workflow is acceptable.
Finally, ask for an item-based split and another close method your bar commonly uses. Check what the guest would be asked to pay and what remains open after one part is settled. If the vendor cannot demonstrate a step, record it as unanswered rather than assuming it will work after installation.
Run a bar-service demo and tab risk matrix
Use this hypothetical scenario with every vendor. Two guests open one tab. The first round has a $12 cocktail with a $3 spirit upgrade and an $8 beer. A second bartender takes over and adds a $10 drink. The drinks total is $33 before any tax or tip. The guests then ask to split the first $15 drink from the remaining $18. This is an order-total example only; it does not include processing fees or other operating costs.
Run the scenario in a sandbox or other simulated mode. Do not use a real card, send a real guest message, or dispatch a courier. Ask the vendor to simulate the authorization and payment outcomes as well. The matrix below turns the demonstration into a record of what matters and what to do if a step fails.
| Step | Acceptance criterion | Risk if unresolved | Decision or fallback |
|---|---|---|---|
| Open tab | Staff can identify and retrieve the right check; simulated authorization status is clear. | Drinks may be added to the wrong tab or staff may misunderstand payment status. | Ask for another lookup method and a written authorization workflow. |
| Enter round | Upgrade and quantities appear correctly; first-round total is $23. | A modifier or correction is missed. | Try the actual menu setup; reject it if staff cannot verify the order before sending. |
| Change bartender | Second employee finds the $23 tab, sees its status, and adds the $10 drink. | An open check is missed at handover or responsibility is unclear. | Document the transfer and closing-manager review; decide whether manual handover is acceptable. |
| Split and close | The simulated split shows $15 and $18, with each part’s status visible. | Staff cannot tell what has been settled or remains due. | Ask for an alternative split method; make it a must-have if this request is common. |
| Exception | Vendor shows a simulated decline or failed close and the next staff action. | A tab appears finished when payment remains unresolved. | Require a manager procedure and a way to find unresolved checks. |
Mark each row pass, fail, or unanswered in your own notes. A pass should mean the proposed configuration meets your criterion, not merely that the vendor has a similarly named feature. Note the devices, staff permissions, and payment setup used. If a workaround requires a manager every time, consider whether that manager will actually be available during your busiest hour.
Add your own exception: a guest leaves before closing, a bartender enters the wrong spirit, or the incoming shift cannot find a tab. Ask what the screen shows and what the manager must do next. You are looking for a recoverable process, not a promise that mistakes never happen.
Compare the complete quote and its dependencies
Request a written quote for the same location, number of devices, payment arrangement, and intended workflow from each vendor. Separate recurring software charges from one-time setup and equipment. The POS hardware decision also affects where staff can take orders and payments; ask which quoted devices are required and which are optional.
Include these categories in the comparison:
- Software: subscriptions, add-ons, and any charge for extra locations or devices.
- Equipment: terminals, payment devices, printers, installation, and replacement terms.
- Payments: processing rates and transaction charges, plus any separate payment-related fees. A quoted processing rate alone is not the all-in operating cost.
- Setup and support: menu preparation, training, support coverage, and any recurring service charge.
- Exceptions: charges for disputes, failed transactions, replacement equipment, or other events listed in the quote.
For a separate hypothetical quote comparison, suppose annual software is $1,200, equipment and setup are $600, and estimated annual processing is $900. The first-year quoted total for those items is $2,700. It includes the stated fixed software and setup costs and the estimated variable processing cost. It excludes exception charges, any unquoted add-ons, and applicable taxes; it is not a sales or deposit figure. Ask for those missing amounts or assumptions before comparing another quote.
Use the same estimated transaction volume and payment mix for each processor quote. If a fee depends on an uncertain event, show it separately rather than treating it as zero. For Fleksa’s published plan details, check Fleksa plans; pricing information was checked in November 2026. Confirm the current quote and what is included for your location.
Ask each vendor about contract length, renewal, cancellation charges, processor requirements, and who owns or leases the equipment. Also ask what staff can still do if internet access fails, whether payments can be taken, and how open checks are reconciled afterward. Do not assume offline payments are available. A qualified adviser can help you assess contract or tax questions that affect your business.
Choose on demonstrated service, then prepare the change
Toast lists restaurant POS, hardware, online ordering, payments, kitchen display systems, and integrations. Square offers restaurant point of sale and related payment and ordering tools. Fleksa offers restaurant POS connected with direct ordering, reservations, and related tools. Ask each vendor to demonstrate your requirements; those product descriptions do not establish how a particular bar-tab workflow will work.
Choose a system that passes your must-have rows under the quoted setup. For example, if staff change shifts with open tabs and item-based splits are common, an inexpensive quote is not enough when transfer or split status remains unanswered. If guests nearly always pay per round, a simpler workflow may be acceptable—provided the payment and correction steps meet your needs. Use cost to compare options that clear the service requirements, not to excuse an unresolved high-risk step.
Before committing, ask who will configure your menu and train each shift. Prepare a restaurant-approved reference menu and check categories, modifiers, quantities, availability, and totals against it. Fleksa’s POS page describes onboarding guidance for preparing the menu and floor; confirm the scope and timing for your setup. If you also need broader tools, ask how the proposed POS connects with the restaurant management software you intend to use.
Practice the tab scenario with staff in simulation first, including a failed payment and handover. A live service pilot is different: plan its scope, staff coverage, support contact, and fallback procedures with the vendor before using the system with actual guests. Keep a way to track unresolved checks during the change, and do not assume a migration will be uninterrupted or that no orders can be missed.
Take the scenario and acceptance criteria to a Fleksa POS demo. Ask the vendor to show each step in the configuration you would buy, record any unanswered rows, and request a written quote for the complete setup.
Frequently asked questions
What is the most important POS feature for a bar?
Start with the workflow your bar depends on most. For a tab-heavy bar, that usually means finding an open check, understanding its payment status, transferring responsibility, and closing it accurately.
Does a card authorization mean the tab is paid?
No. An authorization and a completed payment are different steps. Ask the payment provider how its authorization works, what staff see, and what happens when the final amount changes.
How should a bar compare POS processing fees?
Use the same estimated transaction volume and payment mix for each written quote. Compare processing alongside software, equipment, setup, support, and potential exception charges rather than relying on one rate.
