# Charge Partial Amount

> Charge only part of the cart total — for deposits or split payments.

With POSBridge you can send a **freely chosen amount** to the SumUp terminal — e.g. just a deposit, part of the order, or when a group splits a bill. The amount must be less than the cart total in Shopify POS.

#### Typical use cases

* **Deposit:** Customer pays 50% today — remainder on pickup
* **Split bill:** Group splits the amount across multiple cards
* **Mixed payment:** Part by card (SumUp), rest by cash

*About 2–3 minutes*

<Steps>
  <Step title="Fill the cart">
    Add all items to the Shopify POS cart as usual.
  </Step>

  <Step title="Open POSBridge tile">
    Tap the **SumUp Payment** tile in the Smart Grid. The default is **Full amount** (cart total).
  </Step>

  <Step title="Choose Partial amount">
    Choose **Partial amount** (not **Full amount**) and enter the amount — e.g. `9.50` on a €19.00 cart.
  </Step>

  <Step title="Send payment">
    Tap **Send payment** (not “Start payment”). The partial amount goes to the Solo. The customer chooses a tip **on the terminal**, not in a modal tab.
  </Step>

  <Step title="Record in Shopify">
    After a successful payment, return to Shopify POS. Complete checkout with the **custom payment type** (e.g. SumUp) — only the amount taken on the Solo. Take the rest in cash or leave it open.
  </Step>
</Steps>

<Tip>
  The partial amount is automatically recorded in the Shopify order notes (`posbridge_charged_mode: PARTIAL`). This makes it always traceable in reconciliation how much was paid by card and what was paid by other means.
</Tip>

<Warning>
  **Important:** The partial amount entered must be **less than the current cart total**. POSBridge does not allow an amount exceeding the cart total.
</Warning>

<AccordionGroup>
  <Accordion title="Can I split the same cart across multiple cards?">
    Yes. Open the POSBridge tile multiple times and enter the desired partial amount each time. Each card payment is a separate transaction. Close checkout in Shopify POS only after all payments are complete.
  </Accordion>

  <Accordion title="What happens if the customer pays the remaining amount in cash?">
    After the card payment via POSBridge close checkout in Shopify POS. Select **Cash** for the remaining amount. Shopify POS then records both payment methods on the order.
  </Accordion>

  <Accordion title="Does the partial amount appear under Transactions?">
    Yes. Every transaction — full or partial amount — appears in the app under **Transactions** and is matched to the Shopify order.
