リーダー、タップ決済、カード入力、または現金で支払いを受け付けます。

Short answer: type the amount, tap 次へ (請求 on Android), and the app takes it from there — the card reader or Tap to Pay if one's ready, a card form if not. Cash has its own button. Card sales create a Stripe charge. Cash sales are recorded as a paid invoice, with no charge and no fee.

Before you start

Get your reader or Tap to Pay ready from the menu (the person icon at the top left on iPhone and iPad, or the menu icon on Android):

• Card reader: tap カードリーダーを接続する (iPhone and iPad) or Connect reader (Android).
• Tap to Pay: tap iPhoneのタッチ決済を有効にする or タッチ決済を有効にする (Android). It only shows on phones that support it.

Card reader or Tap to Pay

1. Enter the amount, or add products to the cart.
2. Tap 次へ, then 取引を開始. On Android, tap 請求, then Begin transaction (or タッチ決済).
3. Your customer taps, inserts or swipes their card (or taps their phone or card on yours for Tap to Pay).

Typing in a card

1. Enter the amount and tap 次へ (請求 on Android).
2. No reader connected? The card form opens. Reader connected? Tap the keypad icon at the top right (カード情報を手動で入力してください).
3. Enter the card number, expiry and CVC, then tap 請求.

There's no extra app fee for typed cards, but Stripe charges its online rate (2.9% + 30¢ in the US) instead of the lower in-person rate. More here: Is there a special rate for using a card reader?

Cash

1. Turn on 現金での支払いを許可する in Settings (once per device).
2. Enter the amount, then tap the … button next to 次へ (on Android, the arrow on the right side of the 請求 button).
3. Choose 現金払い and tap 現金支払いを記録する.

Cash needs an internet connection, and the option hides while you're offline. Everything else about cash is here: How do I record cash payments?

Where do my sales show up?

Card sales appear in 支払い in the app and in your Stripe Dashboard. If you sold products, Stripe also shows a matching paid invoice — that's normal: Why does my Stripe Dashboard show two entries for the same product sale?
