Checkout not functioning for some customers

Topic summary

Checkout failures reported by a merchant: some customers see “Checkout is unavailable” when clicking “Buy,” unable to reach the checkout page. Clearing cache/browser does not help. Screenshots were provided to illustrate the errors.

Support engagement: Shopify staff asked if the issue can be replicated, requested existing support ticket numbers, and noted the errors appeared related to Shop Pay/Shop Pay Installments (Shopify’s accelerated checkout and installment payment options). The merchant shared ticket numbers (37794348, 37791120) and emphasized the failure occurs before reaching checkout, suggesting a platform-side issue rather than a specific payment processor.

Latest update: Shopify confirmed a platform incident occurred “yesterday” affecting checkout for some merchants, reportedly lasting under an hour and now resolved.

Next steps: If problems persist, the merchant should reply to the existing tickets with examples of the most recent failed order attempts for further investigation.

Status: Marked resolved by Shopify; awaiting merchant confirmation. Discussion remains open if issues continue.

Thank you for the ticket number @RUdirect

I have investigated this further on my end and I can confirm yesterday there was an issue that affected checkout for some merchants that shouldn’t have lasted for longer than an hour. This issue should be fully resolved now and not causing problems.

If you are still experiencing issues regarding this please reply back to your tickets you shared here to let them know and provide samples of your newest attempted orders that could not complete.
