Singapore durian retailers face a specific squeeze—loose produce graded by the kilogram, packed-box weight barcodes, and cash-heavy weekend crowds. The eight POS systems below were selected for their real, testable fit with those operations: per-weight scale integration, perishable inventory write-offs, PayNow/Nets acceptance, and offline tolerance in wet-market stalls.
1. Qashier
Qashier is headquartered in Singapore and its hardware—the Qashier X1 and Qashier S1 terminals—is built for high-humidity, high-dust counters. For durian sellers, the decisive feature is native weighing scale integration: a USB or Bluetooth scale feeds the price calculation directly into the till, so a customer pointing at a 1.8 kg KXO can be charged at the per-kg price without manual entry. The system also handles split payments between PayNow QR, Nets, and credit cards on a single device, which shortens the queue during the 9pm post-dinner rush at stalls like those along Sims Avenue.
Inventory in Qashier tracks loose fruits by unit entry and packed boxes by barcode, but the real operational win is the waste write-off module. Durian shells and rejected fruits are logged as shrinkage, keeping the stock ledger honest against daily re-stocking from Pasar Karat or the Wholesale Centre. Subscription starts roughly around S$59/month per terminal, with a two-year contract typical for retail-grade hardware pricing.
2. Eats365
Eats365 is a cloud-native F&B POS built specifically for the Singapore food scene, and its strength for durian operations is order flow, not just the till. If your stall runs a sit-down section (for example, placing a table at 239 Bedok Street or a heritage shophouse side lane), the Eats365 queue and table management modules let staff take fruit orders at the seat, send trimming instructions to the back, and close out the bill with PayNow tied into the integrated payment gateway. Online-ordering integration with Oddle and Deliveroo means pre-orders for whole Musang King boxes can be batch-processed without a parallel manual spreadsheet.
For loose stock, Eats365 has a weighed-item plugin that works with common scale protocols (RS232), and it records the grade (D24, Black Thorn, D13) as a product modifier rather than a generic category. That granularity matters for monthly cost-of-goods analysis—you can see exactly how much D24 shell waste is eating into margin. Pricing is approximately S$89/month per outlet, plus a one-time setup at around S$300.
3. Zettle by PayPal
Zettle is the strongest choice for a pop-up durian stall or a seasonal weekend booth at a pasar malam. The card reader costs around S$39, and transaction fees are a flat 2.9% for tap, chip, and PIN—no monthly rental. Pair it with the Zettle Retail app on an Android phone, and you have a working inventory ledger for stock categories like “Frozen XO” and “Fresh D24,” plus basic barcoding for packed boxes.
What Zettle does poorly is complex pricing and scale integration. There is no direct scale driver for loose fruit, so you must price by an entered kilogram amount manually. For a stall selling whole fruits only—you do not need to weigh-cut per segment—Zettle is operationally sufficient and requires zero long-term commitment. If your operation shifts from a weekend booth into a fixed shop, you will outgrow it within a seasonal cycle.
4. Square for Restaurants
Square has had a Singapore presence since 2019 and remains the free-plan champion: the basic POS software has no monthly fee, and card-present transactions cost 3.5% per swipe or tap. For a durian shop selling whole fruits by the piece, Square’s free inventory lets you track units, set low-stock alerts, and print plain thermal receipts. The open API is a serious advantage—you can bridge stock data into Xero or a custom WhatsApp ordering bot for prepaid box reservations.
However, there is no native weighing-scale integration for loose fruit, and Square lacks a true offline mode for congested cellular networks in basement malls. Durian stalls in remote locations like Changi Village or the Seletar area may see the app spin on a dropped 4G connection. For a shop that does 100% piece-based sales of whole fruits and is hooked to a stable Fibre line, Square is the cheapest legally running system in SG. For sellers who weigh out segments, you will need a manual price-typing habit.
5. Loyverse
Loyverse is a genuinely free POS for iOS and Android, and it comes with an offline-first design that keeps the till running even when the mobile signal fails during a Sunday thunderstorm. No monthly fee, no charge per receipt, and a cloud dashboard that syncs when you reach WiFi. For a single-location durian stall with no online store, this is the lowest-maintenance option in this list.
The inventory model supports variants, so a SKU can be “D24 Whole” with variants for “Small (1-2kg),” “Medium (2-3kg),” and “Large (3kg+),” which maps neatly to how Singapore durian stalls price by band rather than exact weight. Loyverse also prints discount or promo receipts cleanly. The catch is scale integration—again, manual entry. Also, payroll and advanced reporting are locked behind a subscription. But for a pushcart or a rented stall counter that must survive a power blip and a slow data day, Loyverse is the resilient pick.
6. FomoPay
FomoPay is a Singapore-based payments platform that pairs a business account with a tap-to-phone POS app—no separate hardware required. Any Android phone with NFC becomes the terminal, and the app accepts Visa, Mastercard, Amex, GrabPay, PayNow, and Nets via the Aggregator Gateway. For a durian truck that rotates locations every night (e.g., different blocks in Tampines, then Toa Payoh), this eliminates the cost of carrying a bulky terminal.
FomoPay’s real strength is the settlement speed. Funds are typically settled to the merchant account the next business day, which matters for a durian buyer going to the wholesale market every morning at 4am with cash in hand. Transaction fees hover around 1.7% to 2.5% depending on volume tier. The app has a simple item catalogue, but inventory tracking is too shallow for a shop running 15 grades. Use FomoPay if your durian business is hot, fast, and mobile—and someone else handles stock accounting.
7. Nets SmartPOS
Nets is the household network in Singapore, and its SmartPOS solution (supported via partner banks like UOB) is the most direct route to compliance. The terminal runs a certified Nets app plus the bank’s merchant portal, and because the acquiring is with Nets, you get access to the Nets QR master for SGQR, which includes PayNow and local e-wallets. If your durian shop sits in a tourist zone like Geylang Serai or Bugis, this is the one system that guarantees a tourist from China can pay with Alipay or WeChat by scanning the union QR.
The SmartPOS app also prints e-invoicing-compliant receipts, which is relevant when your durian wholesale arm sells B2B to restaurants. Hardware costs are subsidized by the bank under merchant agreement; monthly fees are negotiable but typically land at zero if you maintain a minimum transaction volume. Inventory and scale support are rudimentary—the app is a payment-first client, not an operations suite. Pair it with a cheap inventory sheet or a separate Loyverse terminal if you need weighing.
8. POS Panda
POS Panda is a Malaysia-born retail platform with a Singapore data centre and on-the-ground support in Ubi. Its edge is a mature weighed-item module: it supports direct driver updates from Avery Berkel, Dibal, and Mettler Toledo scales, reading the weight into the POS automatically. For a durian stall selling segments of 200g, 300g, and 500g over the counter, this is the only system in this list that performs live scale-driven pricing without a hack.
The system also has multi-outlet inventory with inter-branch transfer, which suits a small chain like a two-location durian operation (e.g., one shop in the east, one in the west) sharing a single fruit supply. The app is heavier than Qashier or Eats365, and the user interface has a slightly dated Windows-POS look. Pricing starts at around S$49/month per register with a minimum one-year contract. If your operation centres on segment-by-weight retail, POS Panda is your pragmatic choice.
