How credits work

Every SMS you send deducts one credit from your workspace balance. Credits are deducted atomically before the message is dispatched — if the balance reaches zero, sends are blocked until you top up. Credits never expire.

​
Pricing tiers

Credits are priced in Mozambican Metical (MZN) via M-Pesa. The per-SMS rate decreases with volume:
TierVolumePrice per SMS
StarterUp to 100 000 credits1.30 MZN
Growth100 001 – 260 000 credits1.20 MZN
EnterpriseAbove 260 000 credits1.00 MZN
The tier is selected automatically based on the quantity you purchase.

​
Buying credits

Purchase credits from the Billing page in your dashboard. You will be redirected to an M-Pesa checkout. Once the payment is confirmed, credits are added to your balance immediately.

​
Zero balance

When your balance reaches zero, sending returns 402: 
{
  "errors": [{ "message": "No SMS credits remaining. Contact support to top up." }]
}
The message is not queued and no charge is made.

​

Low balance notifications

Torpedo automatically notifies your workspace when credits drop below a threshold. You will receive an email reminder to top up before sending is blocked.
