Start with how the bar serves a round
A bar needs more than an item list and a payment button. Guests can keep a tab open, order several rounds, move between a table and the counter, and ask to split the final bill. Staff need to know which drinks have been sent, which were prepared, what was voided, and what remains unpaid.
A bar-and-restaurant operation adds food, kitchen stations, table reservations, and different preparation times. Evaluate the full service with your cashier, bartenders, floor team, and closing manager. A system that looks simple in an empty venue may become awkward when several employees touch the same tab.
Distinguish an open tab, preauthorization, and payment
An open tab groups charges that have not been settled. A card preauthorization checks or reserves an amount according to the payment setup. A captured payment is another event. Closing the screen or printing a bill does not prove that the final payment completed.
For a concrete example of the distinction, Square's U.S. preauthorization documentation separates authorizing a card, managing the authorization, and completing the transaction. That is a functional reference, not a recommendation or evidence that the same flow is available in another product or country.
In the bar's acceptance test, add a round after the initial authorization, split the final bill, decline one payment, and recover without charging the remaining guest twice. Show staff the difference between an unpaid amount, an authorization hold, a tip, and a completed charge.
Evaluate each part of the operating stack
- POS and tabs: named accounts, rounds, staff permissions, transfers, partial payments, void reasons, and an audit trail.
- Order tickets: distinguish drinks for the bar from food for the kitchen, with structured modifiers and a visible preparation state.
- Reservations: basic bookings may be enough for a small venue; deposits, floor plans, pacing, and no-show rules need their own scope.
- Inventory: count sealed products separately from open bottles and recipe ingredients.
- Close and reporting: compare expected tender totals with cash, card settlements, refunds, tips, and outstanding tabs.
- Online ordering: define which products, hours, pickup choices, and delivery rules apply outside the room.
Do not equate a feature label with the workflow. “Split payments” may mean several cards at checkout without supporting later rounds, seat-level bills, or a transferred tab. Demonstrate the exact sequence you need.
Compare free and paid models by the work they leave you
A permanent free software tier can suit a modest operation if its actual limits fit. Check the number of users and devices, open tabs, exports, reports, support, and compatible payment hardware. Zero subscription cost does not mean zero payment-processing or equipment cost.
A free trial is an evaluation period. Record its end date, the paid plan it becomes, what happens to data if you do not subscribe, and whether the trial includes the functions you will actually buy.
Open-source or self-hosted software can provide a different control model. Read the license and budget for installation, backups, security updates, payment integration, compatible printers, and the person who restores service during a shift. Source availability does not guarantee that those jobs are done for you.
A paid hosted service can shift some infrastructure and support work to the provider. Match the proposal to locations, devices, users, required modules, integration services, and usage charges. A paid product is not automatically more suitable; the question is whether the contract and demonstrated workflow cover the job.
A small counter with immediate payment can evaluate a limited free tier differently from a late-night bar with shared tabs and several stations. Use the same acceptance scenario on every option instead of comparing only subscription headlines.
Count what a recipe consumes, not just the bottle sold
For an illustrative bottle example, 750 ml divided into 150 ml servings gives five theoretical servings before any separately recorded loss. Actual serving sizes and recipes belong to the venue's policy. If the POS sells a glass but inventory tracks a bottle, define that conversion rather than subtracting one whole bottle for every glass.
Cocktails introduce several ingredients and modifiers. Record recipe versions, spills, complimentary drinks, breakage, and returns with different reasons. A canceled drink before preparation and a refunded drink already made have different stock consequences.
Use a physical count at a fixed cutoff to compare theoretical and actual stock. The inventory control guide explains those layers, and the Excel ledger provides a simple way to record movements. Product availability on an ordering menu is not a substitute for ingredient recipe inventory.
Run a closing-shift demonstration before choosing
Create a tab, send a drink and food order to their stations, add a second round, move the tab, and void an item with supervisor approval. Split the final payment, add the permitted tip, refund one paid item, and reconcile the shift. Include a printer failure and a lost staff-device connection.
Record who can recover each exception and what happens to the tab, kitchen ticket, stock, and payment. A temporary connection failure must not become an unexplained duplicate charge or two preparation tickets. Decide whether service can continue safely during an outage and how offline records return to the authoritative system.
After the test, compare total operating cost: software, hardware, processing, integrations, training, maintenance, and support. Do not calculate savings without the venue's actual baseline and a matched service scope.
Add a connected ordering layer where it is useful
Ordering.co provides restaurant websites, merchant order handling, and connected catalog, payment, and fulfillment workflows. It also offers table reservations with the scope described on that product page.
These capabilities do not by themselves establish a complete bar POS, card-preauthorization system, seat-based bill splitting, or recipe-costing package. Keep those responsibilities in the tools that demonstrate them, then validate the supported connection to ordering. For staff capture and kitchen handoff, use the digital order-ticket workflow as the basis of the service test.
