# Payment link page

Payment pages are hosted on the pay.gov.sg domain and provide comprehensive information related to the payment, including a summary table with the purpose of the payment and GST breakdown. The fields and layout of the payment page cannot be customised.

## Before payment

Once payers are ready to proceed with the payment, they can click on the "Proceed" button on the payment page. Payers can select from payment modes that your agency chooses to offer through Stripe and pay with the mode of their choice. Payments should be tested on the staging environment using [dummy credit card numbers. ](https://stripe.com/docs/testing)

## After payment

Upon successful payment, the payment link will automatically generate an IRAS-compliant tax invoice/receipt. This document serves as proof of payment and includes all the necessary information for record-keeping and compliance purposes. **Once payment is made, all input fields will be removed and duplicate payments will not be possible.**
