Payment methods
- Add a “Card or electronic payment” (your card terminal, a wallet) or a “Transfer or deposit” with bank, account holder, account number, currency and instructions for the customer. Check “Ask for a reference” if you want the register to ask for the receipt number.
- In Charge by link or QR you paste the keys of your Stripe, PayPal, Mercado Pago, Pagadito or Tilopay account. See Payments.
Currency
- “Base currency”: the one your prices are in. Changing it does not convert the prices; the app asks you to confirm.
- “Other currencies you accept”: up to 3, with their value (for example, the value of 1 USD in córdobas).
- “Cash rounding”: to 0.50, 1 or 5 units.
Fiscal invoice
Turn on “Use fiscal receipt” and fill in the document name, the authorization text, the legend, the series prefix, the next number, the last number of the range and the “Valid until” date. You can ask for the buyer’s document.
The register does not let you take payments when the range runs out or the authorization expires. With multiple tablets, give each one a different series prefix. Each country has its own rules: confirm them with your accountant.
