Guide to integrate MercadoPago physical terminals (Point and QR) in Sarah

Last updated: 2026-04-07

Sarah works with MercadoPago Point and QR so you can take in-store payments from the point of sale using your MercadoPago account.

Initial setup

1. Connect your MercadoPago account

  1. Log in to Sarah.
  2. Go to Cash Registers > Settings.
  3. Select a cash register.
  4. Choose Connect MercadoPago.
  5. Authorize the connection with your MercadoPago account.

Exact steps may vary slightly by screen version; follow the prompts in the app.

2. Set up terminals (Point)

  1. In the cash register settings, open Terminals.
  2. Select the Point devices you will use for that register.
  3. Each device must be active and set up in your MercadoPago account.

3. QR payments

QR is usually available once the account is linked to the register, without extra steps in Sarah. If you do not see it, check the connection or contact support.

Point (card terminal)

Card terminals that accept chip, swipe, or contactless payment.

Typical capabilities:

  • Card payment on the Point device.
  • Immediate feedback on the terminal when the payment is processed.
  • Installments may be available depending on MercadoPago and your setup.

Typical in-store flow:

  1. Build the sale in Sarah’s POS.
  2. Choose Point payment and pick the terminal.
  3. The customer pays on the Point; the device shows the amount.
  4. When MercadoPago confirms the payment, the sale in Sarah updates to reflect the payment.

QR (MercadoPago app)

The customer pays by scanning a code with the MercadoPago app.

Typical capabilities:

  • No Point device required for this mode.
  • The customer confirms payment on their phone.

Typical in-store flow:

  1. Build the sale in the POS.
  2. Choose QR payment; the code (or link) appears on screen as appropriate.
  3. The customer scans and pays in the app.
  4. When payment is confirmed, the sale should show as paid; if it is slow, also check status in your MercadoPago app or dashboard.

What you see in the POS (overview)

What you see in the appWhat it means
Waiting for paymentThe customer has not finished paying yet.
PaidThe payment went through and the sale is marked as collected.
Canceled or incompleteCollection did not finish; you can try another method or start again depending on the screen.

Exact labels may differ slightly in the UI.

Canceling before payment completes

If payment has not finished, you can often cancel from the POS flow and try again. If money has already been collected, reversals follow MercadoPago rules (dashboard or MercadoPago support).

Best practices

  1. Cash register and MercadoPago: keep the linked account and Point devices active in MercadoPago.
  2. Before charging again: if a payment seems stuck, check MercadoPago so you do not double-charge the customer.
  3. Amounts: confirm the POS total is correct before starting Point or QR.
  4. Multiple registers: repeat connection and terminal selection for each register that needs it.

Support

  1. In Sarah, confirm the register is connected and the right terminals are selected.
  2. In MercadoPago, confirm the operation status (app or dashboard).
  3. If it still fails, contact Sarah support with approximate time and register name (avoid sharing unnecessary customer data).
