Automated Payment System for a Grocery Store

I’m looking for a developer to build a simple, automated payment system for my small grocery store to make the checkout and payment process faster and more convenient.

The system should allow customers to pay electronically, with payments processed automatically through a suitable payment method. It should confirm successful transactions, update payment statuses, and maintain transaction records without requiring everything to be handled manually.

The solution should be easy to operate during daily store activities, secure, and affordable to maintain. I’m open to recommendations on the most suitable setup for a small grocery business, including payment gateway integration or a QR-code-based payment option, depending on availability and cost.

The developer should have experience with payment integration, transaction processing, and basic payment automation.

Please outline your proposed solution, any required third-party services, estimated delivery time, and total cost.
