Google Workspace bills are paid through the payment method specified in the Admin Console billing settings. Log in to the Admin Console, go to "Billing", select "Payments" and then you can add/update a credit card, PayPal account, or monthly bank draft for automatic billing.

Google Workspace is billed on a subscription basis. The cost is calculated per user per month and is dependent on the plan that you choose. The billing is flexible, allowing you to add or remove users at any time, and you will only be charged for the active users during the billing period. Google Workspace offers different plans with varying levels of features and storage options, so you can select the one that best suits your needs and budget. The billing is typically done monthly, and you can easily manage and track your invoices and payments through the Google Admin Console.

Google Workspace plans are billed on a monthly or yearly basis, depending on the billing cycle selected in the Admin Console when signing up. Monthly plans allow changing user counts each month, while yearly plans are prepaid for the full year at a slight discount.
