Billing & Usage page showing Billing Summary and Voice Usage Revenue ## Common Tasks ### Check a client's current usage Open the sub account's **Billing** tab to see current Balance, Credits, and (if a monthly package is active) minutes used versus included minutes. ### Understand the usage dashboard For per-minute billing, clients see their available Balance and Credits and a running total as calls complete. For package billing, clients see minutes used out of their included total (e.g., "187 / 200 minutes") and any overage charges accrued once the limit is passed. ### Respond to low balance Balance running low or reaching \$0 triggers dashboard banners and (if configured) email alerts. See [Notifications](/running-your-agency/notifications) to adjust thresholds, or ask the client to top up, or add [Credits](/billing/wallet-credits) yourself. ## Related Articles * [Wallet & Credits](/billing/wallet-credits): how Balance and Credits are consumed * [Pricing Models](/billing/pricing-models): per-minute vs. package billing * [Notifications](/running-your-agency/notifications): configuring low-balance and usage alerts
