1. Devices
Q: I already have a tablet and printer – can I use them for LOOP POS?
A: iPads and Android tablets usually work. LOOP POS supports many popular printers (see the supplier list in POS → Printers). To be sure, send your printer's specifications to our support team to check.
Q: Can I use the Kitchen/Bar feature without a receipt printer?
A: Yes. You just need a tablet or large screen in the kitchen/bar to show the items to prepare.
Q: What if the hardware breaks?
A: LOOP Smart POS hardware has a 12-month warranty. During the warranty, LOOP will check, repair or replace faulty devices.
2. Selling on the POS
Q: Why can't I add a loyalty member to an order?
A: Member features need an active PEKO Rewards Hub plan. Check Settings → Subscription or contact support to activate it.
Q: Why won't a discount code apply?
A: The order must meet the code's conditions (minimum value, eligible items, time window, shop…). For member vouchers, add the member to the order before applying the code. If the order qualifies and it still doesn't apply, contact support.
Q: How do I let customers pay later (on account, or pay when leaving)?
A: In the Admin dashboard, go to POS → POS settings → Pay later and turn it on for the relevant order types (Dine-in, Take away, Delivery). On the POS, after creating the order, tick Pay later on the payment screen and tap Confirm.
Q: Can people who aren't tech-savvy use it?
A: Yes – LOOP POS is designed to be simple. See the other articles in the LOOP POS collection for guides.
Q: My USB printer isn't detected on Android – how do I know if the POS sees it?
A: On the POS, go to Menu → Info & Support. USB Devices (Android) lists connected USB devices (tap refresh to rescan). Help Test runs automatic checks to help support find the problem; this screen also shows the app version to give to support.
Q: How do I print a test page?
A: On the POS, go to Menu → Settings → Printers and tap Test print on the printer.
Q: How do I change the POS language?
A: Tap Menu (☰) → tap the language box under the shop name → choose a language. The POS supports Tiếng Việt, English, ไทย, 中文, 한국어 and 日本語.

Q: What kinds of businesses is LOOP POS for?

A: MInvoice and SInvoice. Set them up in Settings → Integrations → E-invoice (only one provider can be on at a time).
Q: How do I issue a VAT invoice for food delivery app orders (GrabFood, ShopeeFood…)?
If the app price is the same as your counter price:
Receive the app order and enter the items, quantities and counter prices on the POS.
Complete payment or save the order according to your process.
After payment, choose Issue e-invoice.
Enter the delivery app's legal entity details (e.g. Grab Vietnam Co., Ltd.).
Confirm and issue the e-invoice, then send it by email or as the app requires.
If the app price differs from your counter price:
Create a separate category or items on the POS with clear names (e.g. "Item name – FoodApp") at the app price.
If the app has a discount, create a matching discount on the POS.
Enter the order with the adjusted items/prices and take payment.
Choose Issue e-invoice, enter the app's legal entity details, then issue and send the invoice as above.
5. Revenue and reports
Q: Where do I check revenue?
A: Admin dashboard → Reports → Sales, with tabs Sales overview, Transactions, Payments, Products, Time, Delivery, Discounts, Extra fees, Shift and Order mgmt.
Q: Why don't transaction amounts match total revenue?
A: An order created one day and completed the next is counted as revenue on the completion date. When reconciling, use By completed date so the figures match.
