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
Fill the cart
Add all items to the Shopify POS cart as usual.
Open POSBridge tile
Tap the POSBridge SumUp Payment tile in the Smart Grid. POSBridge shows the full cart total by default.
Enter partial amount
Tap the displayed amount (or Change amount). Enter the desired partial amount — e.g. 9.50 for a half-payment on a €19.00 cart. Confirm with Apply.
Send payment
Tap Start payment. The partial amount is sent to the SumUp terminal. The flow is identical to a regular payment: terminal shows amount → customer taps/inserts card → confirmation.
Handle remaining balance
After successful card payment switch back to Shopify POS. Complete checkout — select the manual payment method for the SumUp amount. For any remaining balance (e.g. cash) select another payment method or close checkout with the already paid partial amount.
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.
Important: The partial amount entered must be less than the current cart total. POSBridge does not allow an amount exceeding the cart total.
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.
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.
Does the partial amount appear in POSBridge reconciliation?
Yes. Every transaction — whether full or partial — appears in the POSBridge payments overview and is matched to the corresponding Shopify order.
