How billing works
Topaz is prepaid: you add credit, and calls are paid from your balance. No platform, per-user or per-device fees. You pay for calls and phone numbers ($4.99 a month each) from prepaid credit.
Calling rates
Calls to the US & Canada cost $0.02/min. Inbound calls to your numbers cost $0.01/min. Calls to US & Canada toll-free numbers and calls between your own extensions are free. Calls are billed per minute in 60-second increments, with a 60-second minimum. Full pricing →
Add credit
In the Control panel, open My Account › Usage Charges › Add Credit: it charges the card you saved at signup, and the credit is added straight away. To pay with another card, go to signup.topaz.tel/topup and enter the email you signed up with; we email you a secure link to choose $10, $25, $50 or $100 and pay on Stripe’s hosted checkout.
Automatic top-up
When you sign up we save your card for automatic top-ups: when your credit falls below $5, we add $25. Change or turn this off in the Control panel under My Account › Usage Charges › Add Credit › Auto Recharge.
Your balance
Your balance is shown in the Control panel. We email you when your balance drops below $5. If your credit runs out, paid calls stop until you add more; calls between your own extensions keep working.
Refunds
Unused credit can be refunded on request. Refunds and chargebacks are deducted from your balance.
Card security
Payments are taken on Stripe’s hosted checkout. You enter your card details on Stripe; they never touch Topaz. Stripe keeps the card you save for top-ups.
