Every workspace has a credit balance, and completed calls reduce that balance according to the workspace's pricing. ## How balances change A balance can change when: * included plan credits are added, * the workspace buys a top-up, * calls use credits, or * a white-label reseller transfers credits to or from one of its customer workspaces. Every change appears in the balance history with its date, amount, reason, and any note supplied with a transfer. ## Transfer credits Transfers are a White-Label feature. In the app they live in **Whitelabel Admin** → **Users** → open the customer → **Transfer credits**. Start in **Whitelabel Admin → Users** and open an existing customer workspace to reach **Transfer credits**. This example workspace has no customers yet, so it shows the starting list rather than a transfer dialog. Users — customer list where you open a workspace to transfer credits White-label workspace owners and admins can fund their customer workspaces from their own available balance. They can also reclaim unused credits, provided the customer workspace has enough remaining balance. Transfers are immediate and never allow either workspace to fall below zero. Transfers only reach **customer workspaces** — the separate workspaces Famulor creates when someone signs up on your white-label domain. Additional workspaces you create for yourself from the workspace switcher are not customer workspaces: each one carries its own plan and its own credit balance, and credits cannot be moved between them. Fund such a workspace from inside it: subscribe to a plan or buy a top-up under **Settings → Plan** (see [Plans & add-ons](/billing/plans-and-addons)). ## Buy additional credits Workspace owners can purchase top-up packages from **Billing**. Once payment is confirmed, the new credits appear in the active workspace. ## Where to see usage * **Whitelabel Admin → Users** shows the balance for each customer workspace and provides the transfer action. * **Usage** shows your active workspace's consumption by day and by call. Balances are credits, not cash. Plan pricing and included usage are described in [Plans & Pricing Setup](/admin/plans-and-limits) and [Minutes & billing](/billing/minutes).
