How to set a daily SMS spend limit in CartBoss
Set a daily SMS spend limit in CartBoss under Billing → Spend limit: texts that would cost more than your limit are skipped until midnight UTC. Every account starts at 100€ a day, and the limit itself costs nothing.
Before you begin
Only the organization owner and users with the Manager role can open Billing and change the limit. Editors can't.
See today's spending
- In your CartBoss dashboard, click Billing in the left menu, under Organization.
- Under Daily spend limit at the top, you see what your texts cost today and your limit, for example "42.80€ of 100€ today". The bar turns orange at two thirds and red when the limit is reached.
- Click the Spend limit tab for the details.

Change the limit
- On the Spend limit tab, type a new amount in Daily limit. Any amount from 1€ to 5000€.
- Click Save limit. You see Saved next to the button.

The new limit works from the very next text. You can raise or lower it as often as you like.
What happens when the limit is reached
- A text that would take today's total over the limit is skipped. It is not sent and you don't pay for it. It is not sent later either.
- A smaller text that still fits under the limit is sent.
- At midnight UTC a new day starts and sending starts again by itself. UTC is London winter time: midnight UTC is 1:00 in Central Europe in winter and 2:00 in summer.
- Your balance and auto reload are not affected.
To keep sending today, raise the limit. The next texts go out right away.
Emails we send you
- "You have used two thirds of today's spend limit": at most once a day, when today's total passes two thirds of the limit.
- "Today's spend limit is reached": at most once a day, when the first text is skipped.
Both go to the Billing email in your company profile (see How to add your company details and VAT ID for CartBoss invoices), or to the account owner's email if no billing email is set. Each has a button that opens the Spend limit tab.
Choose a good limit
Look at what you spend on a busy day, such as a sale or Black Friday, and set the limit a bit above it. A limit that is too low skips real recovery messages on your best days. A limit that is too high lets bot traffic cost you more before it stops.
Questions
Is the limit per store or for my whole account?
For the whole organization. All your sites share one daily limit.
When does the day start?
At midnight UTC (London winter time), not at midnight in your time zone.
I got the two-thirds email but I didn't expect that many texts.
Check Sent messages for numbers from countries you don't sell to. That is often bot traffic. See How to protect your store from SMS pumping (fake SMS traffic) or email us at support@cartboss.io and we'll look at it with you.
I can't see the Billing menu.
Your user role is Editor. Ask the owner of your organization or a Manager.
