1.1 Installation and first launch

The installation steps, recommended specifications, reinstalling, replacing your PC, the no-install version, and Windows 7 and 8 environments are covered separately in the installation guide. Here is a summary.

• PC requirements: Windows 10 or 11 (touch monitor recommended) and an internet connection. When you run the installer https://ai-gpayments.com/apkexe/AigpaymentsSetup.exe, a G-PAYMENTS POS shortcut is created on your desktop. Administrator rights are not required.

1.10 Test order

1.12 Automatic updates

POS checks for a new version every time it launches. If there is a new program, it downloads it first, and then a message appears on the login screen: “A new version (version number) has been downloaded — click 'Restart now' to apply it” (the number of the downloaded version appears in the parentheses). Click 지금 다시 켜기 Restart now to restart with the new program, and the screen files are downloaded next. While the update message is displayed, the login button is locked and reads “Log in after update”.

2Table screen

This is the basic screen for doing business. Each table has one tile, and that table's current order is shown inside it.

2.1 Table status indicators

A table tile shows the table number, menu items and quantities, status · elapsed time, and amount. If a table has several orders, an “N orders” badge appears at the top right and the amount shown is the total. When an additional order that you have not checked is received, the badge changes to “N orders +1” and the tile is highlighted in orange. The highlight clears when you open that table.

“12 min” in the status line is the time that has passed since the order was received. For an order that has waited a long time, the tile turns a darker red.

2.2 Order details

• The large number at the top is the order number. Before payment it shows “Received #number”; after payment it shows the order number for the day (1, 2, 3 …).
• ＋ 추가 주문 + Add order: Adds an order to the same table. The order entry screen for that table opens. 3
• Buttons at the bottom: 조리 시작 Start cooking (changes to 서빙 완료 Served when clicked, and to 전달 완료 Handed over for takeout orders) · 현금 받기 Take cash · 결제 QR Payment QR · 단말기 결제 Card terminal payment (purple, shown only on orders before payment; see section 4.9) · 취소 Cancel
• Takeout orders have a 준비완료 알림 Ready notification button. When you click it, a ready notification is sent to the customer's phone and the button changes to “✓ Ready”. In pay-later stores, you can click it even before payment.
• Delete some menu items or change quantities: In the menu table, click 수정 Edit on that row, set the quantity to keep with [−]/[＋], and click 적용 Apply. If the quantity is 0, click 전부 빼기 Remove all. This is possible only for orders before payment, and a “Revised order slip” is printed in the kitchen. While the payment QR is displayed, this button is hidden. When logged in as staff, the same method as the “Opening the cash drawer” setting applies. With the PIN method, the staff PIN window appears; with the Store owner only method, the message “Store owner login is required” is shown. 1.7
• For an order that another customer paid for, “Paid by ○○ · Paid on behalf” is shown below the total. 4.1
• If a table has several orders, the 전체 All tab opens first when you click the table, and you can view each order with its numbered button. For how to pay in bulk, see section 4.4.

To close the details, click [✕] at the top right or click an empty area of the screen.

2.3 Moving tables, merging tables, and the holding area

• When customers move to a different table, drag the table tile and drop it on that table. If the table is empty, the order moves right away; if the table has an order, a “Swap tables” confirmation appears, and then the orders of the two tables are swapped.
• To move to another zone, first drag the tile to the holding area at the bottom, switch zone tabs, and then drag it from the holding area to the new table.
• Orders in the In-store and map takeout / Other orders area are orders without a table number. If you drag one onto an empty table, it becomes an order for that table.

Merging tables (sharing a table)

1. Click 테이블 합치기 Merge tables on the right. If the order details were open, that table is preselected as the “table to keep”.
2. Click the table to keep. You can also select an empty table. Use this when you gather customers from several tables onto one large empty table.
3. Click the table to merge (you can select several). Click again to deselect. The notice bar shows “N orders (M unpaid … KRW)”.
4. Click N번으로 합치기 Merge into table N. The orders of the tables to merge all move to the table to keep, and the merged tables become empty. To stop, click 그만 Stop.

2.4 New order notifications

• Click the card to open that order. The card disappears automatically after a short while.
• In pay-later stores, orders before payment are also shown as “New order” cards, and when the customer completes payment in the app, a separate “Table N payment complete” card is shown (the alert sound is also different).
• If POS is hidden behind another window, the notification badge in the corner of the screen alerts you instead. When a new order is received, it changes color and blinks, and if there is an order you have not checked, the alert sound repeats every 10 seconds. Clicking the badge brings POS to the front. For color, size, and alert sound settings, see section 1.9.

3Entering orders

This is the screen for entering orders you took yourself into POS. You can open it in three places: an empty table (an order for that table), ＋ 추가 주문 + Add order in the order details (adds to the same table), and 포장 · 기타 주문 Takeout · other orders on the right (takeout, contactless, and other orders without a table).

1. Select a category on the left and click a menu item in the middle. A menu item shown faded is sold out. If a menu item shows “Choose option”, the options window opens first when you click it.
2. In the added items on the right, change the quantity with [−]/[＋]. When the quantity reaches 0, the item is removed from the list.
3. For an amount that is not on the menu (such as a service charge), click ＋ 금액 직접 입력 + Enter amount and enter it on the number keypad.
4. Finish entering the order with one of the following.
   • 결제 QR 띄우기 Show payment QR: Enters the order and immediately shows the payment QR for that amount (pay-first order). 4.1
   • 주문만 넣기 Add order only: Enters only the order and takes payment later (pay later or cash). At “Place the order for table N?”, click 예 Yes.

4Payment

There are three ways to pay. The customer scans the payment QR with the Gpay app, pays in cash, or scans the store QR (sticker) at the checkout counter. Whichever method is used, the payment is reflected in POS immediately once it is complete. Stores that use a card terminal separately from POS can also leave a closing record with 단말기 결제 Card terminal payment (4.9).

4.1 Payment QR

1. Click 결제 QR 띄우기 Show payment QR on the order entry screen, or click 결제 QR Payment QR in the order details.
2. The QR and the amount due are shown in large size on the screen. When the customer scans the QR with the Gpay app, a payment screen for that amount opens on the customer's phone. The customer cannot change the amount.
3. When the customer enters the payment screen, POS shows “The customer is paying”. When payment is complete, “Payment confirmed” is shown, then the window closes automatically and the receipt is printed.

• If you have a customer monitor or tablet, the same QR is also shown in large size on the customer screen. 6
• The QR is for that order only. You cannot save it as a photo and use it later.
• Someone in the party can pay for everyone. Even at a table where several customers each ordered in their own app, one person can scan the payment QR and pay for the whole table (latest version of the Gpay app). The order history stays with the people who ordered, and earned mileage goes to the person who paid. POS lists and details show “Paid on behalf (○○)”.

4.2 Store QR (sticker)

Every store has its own store QR. It is the same as the sticker QR attached at the checkout counter, and when you click the 매장 QR Store QR button on the right, the same QR is shown on the screen (use it instead when you do not have the sticker).

• Normally: When a customer scans the sticker, a payment screen where the customer enters the amount opens in the Gpay app. The customer enters the amount and pays. Be sure to check the payment amount.
• While POS is showing a payment QR: Even if a customer scans the sticker, a payment screen opens with the amount of that order fixed. Whether the customer scans the QR on the screen or the sticker at the checkout counter, payment goes to the same order. In this state, the payment QR window shows “Scanning the store QR at the checkout counter also pays for this order”.
• The customer's phone first shows the store, table, order number, and amount, and has only 결제 Pay / 나가기 Exit buttons. If another customer scans the sticker and someone else's order appears, tell them to close it with 나가기 Exit and let the checkout counter know. When you close the payment QR window in POS, the sticker immediately returns to its normal behavior (entering an amount).

4.3 Cash payment

1. Click 현금 받기 Take cash in the order details.
2. Enter the amount received on the number keypad. If it is more than the amount due, the change is shown; if it is less, “Not enough” is shown. Click 받기 Receive.
3. In the “Cash payment” window, check the amounts again. If the customer asks for a cash receipt, enter their phone number; if not, leave it blank and click 확인 OK.
4. If a cash drawer is connected, the drawer opens and the receipt is printed. The order status changes to “Paid”.

4.4 Bulk payment for a table

• When you click a table that has several orders, the 전체 All tab opens first. Each order shows its received and payment times (only the payment time in pay-first stores) at the bottom right, and a new order you have not checked shows “Additional order”. An order that another customer paid for shows “Paid on behalf (○○)”.
• Buttons at the bottom: 전체 조리 시작 Start cooking all (all orders before cooking) · 미결제 전부 현금 All unpaid in cash (pays the total in cash; 1 combined receipt) · 미결제 전부 결제 QR All unpaid by payment QR · 미결제 전부 단말기 All unpaid by card terminal (purple; closes all unpaid orders at once as a card terminal payment; see section 4.9) · 취소 Cancel
• 미결제 전부 결제 QR All unpaid by payment QR: Attaches the same payment tag to the unpaid orders so they are collected with 1 QR code. The customer scans only once, and the total amount is shown. The QR window shows “○ orders bundled · they will be merged into one once paid”, and when you display it, the message “N orders bundled into one QR — they will be merged into one once paid” appears briefly. The orders are merged into one only after payment is complete. If payment is not made, only the tag disappears, and the orders and order numbers stay as they are. If the orders of several customers who each ordered separately are mixed in, “Receiving payment for the orders of several people at once · earned mileage goes to the payer” is also shown. Explain this to the customer.
• 취소 Cancel: A window opens where you choose “Cancel unpaid only” or “Cancel everything including paid orders”. If paid orders are included, owner login or the staff PIN is required, depending on the cancellation permission settings. 4.7
• To pay for each order separately, open only that order with its number button (1, 2, 3 …) and pay. Use this for customers who pay individually.

4.5 Customer bill requests (pay-later stores)

• In a store where customers pay after the meal (pay later), when a customer taps 계산할게요 I'll pay now in the app, “Bill request” appears in POS.
• When you show 결제 QR Payment QR or 미결제 전부 결제 QR All unpaid by payment QR for that table, the badge clears automatically. It also clears when the table pays in cash.

4.6 Additional orders while a QR is displayed

If a new order is received for the same table while the payment QR is displayed (because a customer ordered more in the app or staff entered an additional order), the existing QR may not work for payment. Click 미결제 전부 다시 띄우기 Show all unpaid again in the window to show a new QR that bundles the unpaid orders of that table. If a customer says “the QR does not work”, click this button.

4.7 Canceling orders and payments

• Click 취소 Cancel in the order details, then click 예 Yes at “Are you sure you want to cancel?” An order before payment is deleted immediately.
• When you cancel a paid order, the customer is refunded (app payments are refunded through the app; cash is paid out from the drawer). Because of this, you set cancellation permission in 1.7 Staff permissions. The default is Store owner only. When logged in as staff, depending on the setting, either the message “Store owner login is required” appears or the staff PIN window opens.
• When you cancel, a cancellation receipt (sales cancellation slip) is printed automatically (Settings > Printer connection > Auto print cancellation receipts). Give this slip to customers who paid by card or app.
• If a table has several orders, choose “Unpaid only / Everything including paid” at 취소 Cancel on the 전체 All tab. 4.4
• To remove just one menu item or reduce its quantity instead of canceling the whole order, use 수정 Edit on the menu row in the order details (orders before payment only). 2.2

Canceling an order that has been paid and served

An order that is fully paid disappears from the table screen and the order list, so you cannot find it to cancel with 취소 Cancel in the order details. Cancel it from the Receipt history.

1. Click Receipt history in the tabs at the top, then click the row of the order to cancel. If it is not today's order, find it with the period chips (Yesterday · 7 days · 30 days · Period…).

4. The button changes to “Canceling…”, and when it finishes, “Canceled” appears on the history row and the preview changes to look like a cancellation receipt (red title, negative amounts). The cancellation receipt is printed.

• 결제 취소 Cancel payment is shown only for orders that have been fully paid. It is not shown for orders before payment, orders that are already canceled, or when the history could not be loaded from the server and an “Offline copy” mark appears at the top of the history (check your internet connection and reopen the history).
• Because the order has already been served, no cancellation order slip is printed in the kitchen.
• When you cancel a card payment, a cancellation of the card approval is requested as well. A card payment can be canceled only on the same day. Whether staff can cancel when logged in as staff (Store owner only · PIN · Same day only · Allow staff) follows the settings in section 1.7, and if the cancellation is refused, the reason is shown on the screen.

4.8 Receipt reissue and receipt history

• When payment is complete, the receipt is printed automatically. To print it again, open the order details and click 영수증 Receipt on the right.
• Find earlier receipts on the Receipt history tab. Type in the search field at the top, and use the chips on the right (All · Order number · Table · Menu · Amount) to choose what to search by. You can also view past dates with the period chips (Today · Yesterday · 7 days · 30 days · Period…).
• Click 영수증 Receipt on the right of a row to print it again right away. A canceled order is printed as 취소 영수증 Cancellation receipt (an order closed with “Card terminal payment” is not a cancellation, but a regular 영수증 Receipt. See section 4.9). If you click the row itself, a receipt preview opens on the right, and you can print it with 영수증 인쇄 Print receipt in the preview or cancel it with 결제 취소 Cancel payment. 4.7
• When logged in as staff, you cannot view history from before yesterday. If you need earlier dates, check after logging in as owner.

4.9 When you take payment on a card terminal (terminal payment)

This feature is for stores that use a card terminal (card reader) separately from POS. It records an order the customer paid for on the card terminal as a closing record in POS. The card approval is obtained on the terminal; POS shows the amount and then closes the order. 단말기 결제 Card terminal payment is shown only for orders before payment.

1. Click 단말기 결제 Card terminal payment (purple) in the order details. If a table has several unpaid orders, click 미결제 전부 단말기 All unpaid by card terminal on the 전체 All tab.
2. The “Card terminal payment” window shows the amount due and the order list. At the same time, the customer screen shows “Paying by card terminal” and the amount.
3. Enter this amount into the card terminal exactly as shown and get approval with the customer's card. If a separate receipt is needed, check Print guide slip in the window (the POS printer prints 1 slip with the payment method “Card terminal (outside POS)”; this is separate from the card slip printed by the terminal).
4. When the approval is done, click 단말기 승인 끝 — 마감 Terminal approved — close out. A message “Closed as a terminal payment — N orders · N KRW (not counted in POS sales)” is shown and the order is closed. If the terminal declined the card, or you want to stop, click 돌아가기 Go back. The order stays as it is.
