Protecting already-won revenue at the point of delivery

A leading multinational retailer serving millions of customers across multiple store formats and channels.

For home delivery orders paid at the customer’s doorstep, store operators used mobile POS terminals to collect payment. Before completing the charge, the terminal had to reach a store service to validate the sales ticket, apply eligible card promotions, and enforce restricted-product rules.

Mobile connectivity could be unstable, and the local store service could also become unavailable. A failed connection could leave the payment stalled after the order had already been picked, packed, and delivered. With an estimated $700,000 in monthly sales exposed, the retailer needed a more resilient payment path without removing important validations from the normal flow.

Retail POS integration and payment continuity for home delivery, connecting mobile terminals with ticket validation, card promotions, restricted-product controls, and alternate transaction paths.

Redesigned the validation flow with controlled retries and routing to a similarly configured alternate store. If validation still could not be completed, the terminal gave the operator a clear choice to stop or continue the payment.

1. Connected mobile payment terminals to store services for ticket, promotion, and restricted-product validation.
2. Routed requests to a similarly configured alternate store when the local service was unavailable.
3. Added controlled retries and a clear prompt to stop or continue the payment when validation could not be completed.
4. Tested, piloted, and rolled out the solution across major store formats and supported terminal models.
5. Embedded continuous testing, monitoring, and security as new offerings were integrated.
