SumUp + Shopify POS Integration 2026: Workflow, Capabilities & Limitations
How SumUp, Shopify POS and POSBridge work together: roles, checkout workflow, capabilities and limitations.
· 2 min
Connecting SumUp to Shopify POS does not create one single payment system. Shopify POS builds the cart, POSBridge connects the workflow and SumUp processes the card transaction.
For installation steps, see our existing step-by-step setup guide. This article focuses on architecture, capabilities and limitations.
The roles
| System | Role |
|---|---|
| Shopify POS | Cart, products, customers, order and inventory |
| POSBridge | Read amount, select terminal, send amount and monitor status |
| SumUp Solo | Customer-facing card terminal |
| SumUp | Process the transaction and handle payout |
Why SumUp Solo?
SumUp provides a Cloud API for Solo that can initiate in-person transactions and retrieve their status. That allows the POSBridge workflow to communicate through the cloud.
Checkout workflow
- Build the cart in Shopify POS.
- Open POSBridge.
- Read the cart amount.
- Address the assigned Solo.
- Customer pays.
- SumUp processes the transaction.
- POSBridge displays status.
- Select the custom payment method in Shopify POS.
- Complete the sale.
What does the integration improve?
- No duplicate amount entry.
- Terminal and location assignment.
- Payment status inside the POSBridge workflow.
- Cloud communication instead of mandatory local pairing.
What remains separate?
- SumUp remains the payment processor.
- POSBridge is not a Shopify payment gateway.
- Staff complete the Shopify sale after the SumUp payment.
- Fees and regulatory obligations remain dependent on provider and country.
Which reader is supported?
The current POSBridge Cloud API workflow is designed for SumUp Solo. Solo Lite, Air and older readers are not part of this specific workflow.
Conclusion
POSBridge is a workflow integration: Shopify POS creates the sale, POSBridge transfers the amount, SumUp processes payment and Shopify POS completes the order.
