A. 1. Expand the payment options by integrating popular payment gateways such as PayPal, Apple Pay, or Google Pay. This can provide users with more flexibility in how they choose to pay. 2. Offer a 'buy now, pay later' option through services like Afterpay or Klarna, which can help users who may not have the full amount available at the time of purchase.

B. 3. Provide clear information on the payment options available on the website, including any limitations. This can help users understand what methods they can use before they start the checkout process. 4. Consider implementing a feedback mechanism where users can suggest additional payment methods they would like to see, allowing the software to adapt to user needs.
