Why do I need text credits?
There’s no requirement to purchase SMS credits, unless you want to use features in WriteUpp that rely on SMS technology.
The following features use SMS credits:
Appointment communications (e.g. confirmations, reminders)
Text verification in Online Booking (optional security feature)
Messages to clients
Messages to colleagues
Direct Messaging
Smart Forms
Two-Factor Authentication (2FA) - required during setup and as a backup login method
1 SMS credit = approx. 160 characters
Longer messages may use more than one credit.
Credits are sold in bundles
You can purchase as many as needed based on your usage.
If you plan to use any of the above features, you’ll need SMS credits to enable them.
