# Payments and Collection Methods in POS

Sarah's Point of Sale module allows you to **collect sales with different payment methods** and record each cash operation.

## Supported payment methods

Depending on your company's configuration, you can use a combination of:

- **Cash**
- **Cards** (recorded as card payment or external POS)
- **MercadoPago** (direct integration with cash registers / connected devices)
- Other custom methods (transfer, accounts receivable, etc.).

## Basic collection flow

1. Build the cart with products the customer will buy.
2. Select the customer if you need to invoice A/B or record the sale in someone's name.
3. Click **Collect**.
4. Choose the **payment method** or combine several (for example, part cash and part card).
5. Confirm the collection and issue the corresponding receipt.

## Cash collections

When you choose cash:

- You can indicate the **amount given by the customer**.
- The system calculates the **change** automatically.
- The movement is recorded in the corresponding cash register.

This payment type is ideal for fast counter operations.

## MercadoPago collections

If you have MercadoPago integration configured:

1. Select **MercadoPago** as payment method.
2. The system generates the payment order (QR or Point) using integration endpoints.
3. The customer pays with their wallet / card on the device/QR.
4. Sarah waits for MercadoPago confirmation (webhook) and reflects the payment status.

Advantages:

- You don't need to manually enter amounts.
- The receipt is linked to the actual collection operation.

> The technical configuration of MercadoPago integration is detailed in the  
> [Integrations · MercadoPago](/docs/api/integrations/mercadopago) section.

## Mixed payments

In some sales you can combine several payment methods (for example, cash + card).

In those cases:

1. From the collection screen, add the **first payment method** and its amount.
2. Add a **second payment method** to complete the total.
3. Verify that the sum of all methods matches the sale total.

The system will record each part as an independent cash movement.

## Payment surcharges

Some boxes (cash registers) can have a **payment surcharge percentage** configured. When you select a payment method linked to a box with a surcharge:

- The **Payment** and **Quick invoice** modals calculate the surcharge automatically based on the amount and the box’s percentage.
- The **invoice** shows the payment surcharge clearly in the total (subtotal + surcharge = total).
- Surcharge percentages are defined per box and appear in the **Boxes** table and in the box configuration labels.

This lets you pass on card or other payment costs to the customer when required by your business.

## Relationship with cash register and reports

Each collection will record:

- The **amount**, the **payment method**, and the associated **cash register**.
- The user who performed the operation.
- The linked receipt (invoice, ticket, note, etc.).

This allows your cash register and sales reports to accurately reflect:

- What was collected.
- How it was collected.
- In which shift/cash register it was recorded.

**Cash Registers and Shifts** section in the features documentation.
