Coffee Shop POS Software

Item selection with modifier trees built for coffee -- size (short, tall, grande, custom oz), milk type (whole, oat, almond, soy, coconut, dairy-free upcharge), temperature (hot, iced, blended, custom degrees), extras (extra shot, decaf, half-caff, syrup flavour, sugar-free), and customisations (light foam, extra foam, no foam, upside-down) -- structured so the most common configuration is two taps and the unusual combinations are reachable without navigating sub-menus. Modifier groups are ordered by selection frequency so the layout matches how baristas actually build drinks, reducing tap count at peak service.

Card-present payments use the Square Terminal SDK or Stripe Terminal SDK for chip-and-contactless transactions, with the POS sending a payment intent to the Stripe Terminal or Square reader via the local network SDK and receiving a payment confirmation before order routing. This flow keeps card data entirely within PCI-compliant SDK scope -- the POS application never handles raw card data. Split payment across cash, card, and loyalty balance handles the common case of a customer splitting between a gift card and credit card without requiring the barista to manually calculate the split amount. Order notes print cleanly to the barista display with the note text visually distinct from the modifier list. Void and refund workflows require manager PIN authorisation. Tax rate configuration by item category -- food at one rate, beverages at another, retail merchandise at a third -- applies the correct rate automatically without the barista selecting it.

Customer lookup at the POS by phone number entry or QR code scan from the loyalty app -- no separate device, no second screen, and no manual check required by the barista. The lookup resolves in under a second via a local cache of recently active customers plus a real-time API call to the central customer database for less frequent visitors. Visit-based points accumulate at a defined rate (for example, 1 point per visit or 10 points per dollar spent), and spend-based thresholds automatically unlock rewards (a free drink at 100 points, a food item at 200 points).

Redemption at checkout displays the customer's current points balance and available rewards on the POS screen before the customer confirms payment, so the barista can prompt the customer about their eligible reward without the customer having to open a separate app. Tier status -- Bronze, Silver, Gold, or your defined tier names -- is shown at lookup so baristas can acknowledge loyal customers by name and offer tier-specific benefits (free size upgrade, priority preparation) without a separate check. Reward eligibility is flagged automatically by the POS so no staff judgement is required at the counter. Visit streaks (for example, every 7th visit is free) are tracked and displayed at the point of completion. The full loyalty record -- visit history, points balance, tier status, redeemed rewards, and campaign eligibility -- syncs to the central customer database for use in marketing campaigns, win-back offers, and birthday rewards sent via email or push notification.

Orders route to the correct KDS (kitchen display system) station at the moment of payment -- espresso bar for hot drinks, cold-drinks station for iced and blended, food-prep station for baked goods and hot food, and drive-through or takeaway labelling for orders to go. Routing rules are configured per item category so a hot latte goes to the espresso display, an iced frappuccino goes to the cold-drinks display, and a toasted sandwich goes to the food display simultaneously, without the barista deciding which station handles it.

Order timer on each KDS ticket shows time since payment was taken, changing colour at your defined threshold (typically yellow at 3 minutes, red at 5 minutes for cafe service) to prompt the team to prioritise ageing orders. Item-level ready confirmation lets the espresso barista mark the drink as ready on the KDS, which triggers a customer notification (name call or digital display board update) and records the actual preparation time against the order. Priority flags highlight large group orders (configurable threshold -- for example, 5 or more items) and special dietary requirements (dairy-free, nut allergy, coeliac) with a visual indicator so baristas handle them with appropriate care. Mobile orders from the app arrive on the KDS with an estimated pick-up time already calculated, so the barista knows when to start preparation to have the order ready at the right moment. Display layout is configurable per station so each barista sees only the line items relevant to their position, reducing visual noise during peak service.

POS processes transactions locally when internet connectivity drops using a SQLite local queue that records every transaction to device storage as the primary write, syncing to the cloud database when connectivity is restored. Cash transactions are recorded immediately with no dependency on network connectivity. Card-present transactions via the Stripe Terminal or Square Terminal SDK can also process in offline mode within the SDK's limits -- the terminal stores the transaction locally and completes the authorisation when connectivity returns, within the SDK's defined offline transaction window and per-transaction limit.

Orders route to KDS stations via the local network (LAN) even when internet connectivity is unavailable, so barista display routing continues uninterrupted during an ISP outage. The POS and KDS communicate on the local network directly, with the internet connection required only for cloud sync, payment processing, and reporting -- not for the core transaction and routing flow. The sync log on reconnection shows every transaction processed during the offline period with timestamp, items, payment method, and sync status, so the owner has a complete record of what occurred and what was reconciled. End-of-day cash reconciliation compares the physical cash count against the POS cash transaction total for the shift, flagging the variance and recording the cash-out amount, so the daily cash close is a 2-minute task rather than a 20-minute manual count. Labour scheduling with shift management assigns baristas to opening, morning rush, midday, and closing shifts with the scheduled hours visible to both the barista and the manager, and actual clock-in/out times recorded for payroll export.

Top-selling items by time of day, day of week, and location show exactly when and where each drink sells -- the data that tells you whether to staff up the espresso bar at 8am or whether your Saturday 11am rush is actually a food sale opportunity. Hourly transaction volume heatmaps identify the 30-minute windows where queue time is longest so staffing decisions are based on actual throughput data, not intuition.

Inventory tracking records stock levels against par quantities for core ingredients (milk, coffee beans, syrup, cups) with par-level alerts triggered when stock falls below the defined minimum. Waste logging records discarded drinks by reason (made in error, quality issue, customer return) against the barista who logged the waste, giving the owner data to address training gaps without relying on verbal reports. Product margin by item accounts for variable costs including milk type (oat milk typically costs 3 to 4 times whole milk per litre) so the actual margin on an oat flat white is calculated rather than estimated. Payment method split shows the proportion of transactions across cash, card, contactless, mobile order, and loyalty redemption -- useful for negotiating card processing rates when the data shows a high contactless volume. Barista performance metrics show transactions handled per shift, average transaction build time, void rate, and upsell rate (percentage of transactions with an added food item). Daily, weekly, and monthly summaries are generated automatically and delivered to the owner's email or dashboard without requiring access to the POS terminal, so performance data is available from anywhere.

Central menu management pushes changes to all locations simultaneously -- price updates, seasonal item additions, sold-out flags, and promotional item activations applied from a head-office dashboard rather than requiring a manager to log into each terminal individually. Menu changes take effect at each terminal on the next menu refresh cycle, which is configurable (typically every 5 minutes during service) to avoid disrupting a transaction mid-build. Location-specific menu exceptions allow one location to carry an item that others do not, or to apply a location-level price override where operating costs differ.

Location-level sales reporting shows each site's daily revenue, transaction count, average transaction value, and top-selling items individually and in aggregate across the group. Cross-site stock management handles groups with a central bakery, commissary, or roastery supplying multiple cafes -- stock transfers between sites are recorded with the sending and receiving location, and receiving location inventory is updated automatically on transfer confirmation. Square and Clover are the reference platforms for single-site operators evaluating whether to continue with an off-the-shelf system or move to a custom build: Square's multi-location functionality covers most needs up to around five to ten sites; beyond that, the reporting flexibility, custom loyalty mechanics, and subscription product support that a custom build provides tend to justify the investment. Staff management assigns baristas to locations with role-based permission levels -- barista, shift manager, and manager -- so a shift manager can apply a discretionary refund but cannot access payroll or multi-location reporting. The architecture scales from two locations to twenty without requiring infrastructure changes.
