sunday

sunday is a payment company built specifically for hospitality businesses such as restaurants, bars, and hotels. It provides QR code pay-at-table, click‑to‑pay links, smart payment terminals, ordering, loyalty integration, and analytics so venues can speed up checkout, increase tips, and streamline operations. Guests typically scan a QR code on the table or receipt, see their detailed bill in real time, split it with others, add a tip, and pay securely with a card or digital wallet like Apple Pay or Google Pay—often without downloading an app.([linkedin.com](https://www.linkedin.com/company/sundaytech?utm_source=openai))

A charge from sunday on a card statement usually means you paid a check at a participating restaurant or bar using sunday’s payment flow. The descriptor may reference Apple Pay or other wallets because sunday can process tokenized wallet transactions on behalf of the restaurant; the underlying purchase is still your meal or drinks at that venue. In some markets, sunday may add a small service fee for using its digital checkout, which can also appear as part of the sunday transaction.([sundayapp.com](https://sundayapp.com/user-terms-of-service/))

To verify a sunday charge, you can look up the date and amount in your email or SMS receipts, or retrieve your digital receipt by revisiting the QR link if available. Guests who created a sunday account can see their order history and receipts there. If something looks wrong—such as a duplicate charge, incorrect amount, or an unexpected fee—you can first contact the restaurant directly, then reach out to sunday support (support@sundayapp.com) with the last four digits of your card, transaction date, amount, and restaurant name. They provide tools for restaurants to review payments, manage chargebacks, and issue refunds when appropriate.([sundayapp.com](https://sundayapp.com/user-terms-of-service/))
