Running a team
Billing
Decide which plan the account needs, since only the owner sees Billings and changes the plan.
Billings shows Pricing and Invoices tabs, with Monthly, Quarterly and Yearly billing cycles. Free has one inspector, no admin and one template. Solo has one inspector, one admin and unlimited templates. Team has three inspectors, unlimited admins and templates, and allows add-ons.
Upgrading from Free starts a checkout. A change on a paid plan updates the existing subscription.
The step is in Help: Billings.
