Existing Qashier merchants able to add/update card details for their subscription renewal themselves via QashierHQ Website
Step-by-step
Enter and log into QashierHQ website
On the left navigator tab, under My Plan & Add-Ons menu, select "Manage My Plan"
In Manage My Plan page, your Qashier plan will appear together with next billing date information
Click at "Update Payment Method" link, pop-up box will appear to fill out card information
In the pop-up box, fill in card information to be used for your subscription renewal.
Notice: When adding your card details, please do not click "Pay Now" unless you intend to settle all your open invoices immediately. Clicking this option will trigger payment for all outstanding invoices, which may require additional steps for refunds if done unintentionally. Qashier recommends reviewing this process carefully to avoid unnecessary transactions.
