Selling with POS

Browse your products, build a cart, and take payment right from the POS screen.

Browse and filter the product catalog

Find products fast on the POS screen using categories, view modes, and search.

  1. Open the POS screen. Products appear for the location selected in the header.
  2. Tap a category chip to filter products quickly, or tap All Products to see every product.
  3. Switch the view mode between All Products, Custom, and Best Sales.
    • All Products: Shows every product.
    • Custom: Shows the products you starred on the Products tab.
    • Best Sales: Shows products above your store's best-seller threshold.
  4. Or search by product name to see stock per option, category, price, and image, with up to 8 results.
  • When an event is live, displayed prices already include the event's markup, currency, and rounding.
  • Sold-out options still appear but are disabled.

Add a product to the cart

Pick an option, set the quantity, add any services, and drop the item into the cart.

  1. Tap a product card on the POS screen.
  2. Choose a variant or option. Each shows its own price, and sold-out options are disabled.
  3. Set the quantity. It is capped to available stock when inventory tracking is on.
  4. Add additional services as the customer needs, such as an extra packaging fee, or add a one-off custom service. Enter a name of up to 30 characters. If the price is $0, the system asks you to confirm that it is a free service.
  5. Tap Add to Cart to see a confirmation.
  • The cart lives only on this device and is not synced to other devices.
  • Identical lines without customizations merge into one.
  • With inventory tracking off, stock caps do not apply.

Sell a custom-priced or fully custom item

Charge a one-off price on an existing product, or ring up an item that is not in your catalog.

  1. For a custom price on a real product, choose the Custom option in the product dialog, then enter a description of up to 20 characters and a price.
  2. For an item that is not in your catalog, tap Add Custom Item in the cart, then enter a name of up to 30 characters, a price, and a quantity.
  3. A $0 price asks you to confirm a free item.
  • A custom option of a real product still counts toward that product's sales stats.
  • A fully custom item stands alone and never affects stock.
  • Custom prices are typed in the currency the POS is showing, such as yen during a JPY event, and are used exactly as typed, with no event adjustment, conversion, or rounding.

Manage the cart

Adjust quantities and prices, remove lines, or clear the cart before checkout.

  1. Tap the cart icon to edit item quantities and check any discounts.
  2. Change an item's quantity with the plus and minus buttons. The maximum is the current stock plus the oversell limit set in Sales and inventory preferences.
  3. Adjust a single item's price: add a markup or a discount to an individual item, as a flat amount or a percentage. A discount can't be more than the item and its additional services combined, and a percentage discount can be at most 100%.
  4. Remove a single line or tap Clear to empty the whole cart. Both ask you to confirm, and clearing shows the item count.
  • If you accept pre-orders, use the oversell limit to set how many extra orders you are willing to take, so you never accept more than you can make or supply.
  • When you open the cart, items are re-checked against current stock. Over-limit quantities are trimmed with a notice. If an item is no longer available, checkout is blocked, so remove the item first to continue.
  • For how the total is calculated, see How the cart total is calculated.

How the cart total is calculated

The cart total is worked out in a fixed order, so you can check it before checkout.

  1. Add each item's price and its additional services.
  2. Apply the item's markup or discount, then multiply by the quantity.
  3. Add up all the items to get the subtotal.
  4. If tax is on or a live event sets a checkout fee, the system works them out from the subtotal and adds them to the total.
  • Example

    Say you sell at a JPY event with these settings:

    • Exchange rate: 1 TWD = 4.83 JPY
    • Event markup: 10%
    • Event price rounding: ¥50 steps
    • Checkout fee: ¥50
    • Tax rate: 1%

    The cart holds:

    • 2 items priced NT$100, each with a 10% discount
    • 1 custom item priced ¥300

    The calculation works like this:

    • Event item price: An item priced NT$100 is converted at the exchange rate, marked up 10%, then rounded by the event rules, so it sells for ¥550.
    • Two items: Each ¥550 item with a 10% discount comes to ¥495, so two come to ¥990. The event rules don't round this discount.
    • Custom item: The ¥300 custom item is used exactly as typed, with no rounding, so the subtotal is ¥1,290.
    • Tax and fee: Tax is ¥12.90. Adding the ¥50 checkout fee makes the total ¥1,352.90.
    • Displayed total: The screen shows ¥1,353.
  • Flat-amount markups and discounts use the currency the POS is currently showing.
  • An event can set its own tax rate. While the event is live, it replaces the store's default tax rate.

Mark cart items as pre-order

Sell items that are ordered but not yet in stock.

  1. In the cart, tap the clock-icon pre-order toggle on a line to sell it as ordered but not in stock.
  2. If a sold-out item is still within the oversell limit, pre-order turns on automatically.
  • This is relevant when inventory tracking is on.
  • A line that is partly in stock splits automatically into an in-stock portion and a pre-order portion.
  • Pre-order lines are paid at checkout and decrease stock; you track fulfillment later from Sales history, as there is no fulfillment screen in POS.

Tag a sale with customers and tags

Attach customers and transaction tags to a sale before you check out.

  1. Open the Tags picker in the cart totals area.
  2. Quick-tap your frequent transaction tags, or open the picker to search customers and tags.
  3. Review the selected badges. They also appear on the checkout summary.
  • The sale records the customers and tags you selected, and the selections clear after each sale.
  • Customer and tag features are available on all plans, but access is paused while a subscription is past due or canceled.

Check out and record payment

Confirm the total, note how the customer paid, and complete the sale.

  1. Tap Checkout in the cart. The dialog shows the total, item count, and any customer or tag badges.
  2. Choose how the customer paid: Card, Cash, App, or ACH.
  3. Slide to confirm the charge for the amount shown.
  4. Wait for the Payment Successful screen. After a moment the cart clears and closes.
  • The sale is recorded with a transaction ID, timestamps, and the operator's identity. It appears in Sales history right away, and stock is decreased for tracked items. Sales made with the Time Machine are the exception: they're recorded at the past time you chose.
  • The payment method is a label only. It records how the customer paid, but the app does not process card, bank, or app charges.
  • Checkout is blocked once you reach your monthly transaction limit, and a dialog offers an upgrade. The limits are Free 50 per month, Grow 3,000 per month, and Max unlimited.
  • If stock is insufficient, the affected items are blocked until you adjust them.
  • Just before charging, the POS re-checks prices against the current event pricing. If anything changed, it updates the cart and asks you to check the total and charge again.
  • If you entered custom prices or fixed discounts while a different display currency was showing, you're asked to re-enter them before checking out.

Sell under a live event

Apply an event's pricing rules across the whole store while it is live.

  1. Tap the event badge in the app header. It is auto-selected for the current period.
  2. Toggle an in-period event live or off. If auto-live is enabled you are asked to confirm, and confirming turns auto-live off.
  3. While the event is live, the POS, cart, and checkout automatically apply its markup, display currency and rounding, transaction fee, and tax override.
  • Sales record the event, the currency actually used, and the event's fee and tax.
  • Events open and close automatically at their start and end times. All-day events stay live for their whole date range, and a timed event takes the live slot for its window before the all-day event resumes.
  • Only one event is live at a time, and the live state applies store-wide to every operator.

Multiple operators on one store

Sell from several devices at once, with each sale stamped by the operator who made it.

  1. Have team members sign in on their own devices to sell at the same time.
  2. Review who made each sale in Sales history, where every sale shows the operator's name.
  • The number of team members depends on your plan: Free 1, Grow 10, Max 50.
  • If two operators sell the same item at the same time, the second may be blocked for insufficient stock or see quantities trimmed.
  • Carts are per-device and not shared, while an event's live state applies store-wide.

Record a past sale - Time Machine

Use the Time Machine to record sales that happened in the past, like a market day you rang up on paper.

  1. Open the Sales section and tap Time Machine in the toolbar, next to Filter.
  2. Pick the past date and time, in your store's timezone, no earlier than your plan's history window allows.
  3. Optionally choose an event that was active at that time. It's recorded on the sale, but the event's custom pricing is not applied.
  4. Confirm to jump to the POS. A glowing border and a banner show the time you traveled to, the selected event, and an Exit button.
  5. Check out as normal. You can record several sales in one trip, and each is saved at the traveled time. Tap the banner to adjust the time or event mid-session.
  6. Tap Exit to end the session and return to the Sales section, where your new records are visible.
  • Available to Store Owners and Admins.
  • Entering and exiting the Time Machine clears your cart. A warning appears before entry if the cart isn't empty. Adjusting the time mid-session keeps the cart.
  • Backdated sales show a small history-clock icon next to the sale time in Sales history, and the details show both the sale time and when it was entered.
  • Stock is decreased normally, and each sale counts toward the current month's transaction limit.
  • Products, Sales, Settings, and search are locked while traveling. Navigating away exits the Time Machine.
  • Checkout requires an internet connection. Going offline pauses checkout but keeps the Time Machine open and your cart intact.
  • Prices are today's values in your store currency. Adjust them in the cart if you need historical prices.
