Voice calls in Commslayer are billed on a pay-as-you-go basis, separately from your main Commslayer subscription.
Voice is billed by usage, so it needs a current paid plan. It isn't available on the Free plan or legacy plans. On those plans, the app shows Phone support is billed by the minute when you try to add a number. Pick a current plan in Settings → Subscription first. Nothing changes until you approve the plan on Shopify. On a legacy plan you can also contact support from the chat inside the app, and the team reviews your plan with you.
How billing works
Calls are billed per minute. The rate covers:
- Carrier fees
- Conference fees
- Recording fees
Billing applies to all calls, including unanswered calls and voicemail. Each phone number has its own monthly spending limit and a fixed monthly fee, listed per number under your monthly add-ons.
Receiving and making calls have different rates. The receiving rate follows the country of your number. The rate for calls you make depends on the country you call.
Recordings, transcripts and AI call summaries are included at no extra charge.
Spending limits
Each phone number has its own monthly spending cap. Once the cap is reached, calls from that number stop until the next billing cycle or until the limit is increased.
To view or adjust your spending limit:
-
Go to Settings → Usage & billing

-
Find the Phone numbers section
-
Click the slider icon next to the phone number you want to manage

-
Adjust the spending limit using the + and − controls
-
Click Save

A limit of 0 doesn't switch calling off. It removes the limit for that number, which then shows No limit. Keep a limit above 0 on every number. To stop the monthly fee for a number you no longer use, release it in the inbox settings.
Viewing usage
To see your current usage and call history:
- Go to Settings → Usage & billing
- Find the Phone numbers section
- You'll see each phone number with its current usage (in dollars and minutes) relative to its spending limit

View rates
To see the per-minute rates for your region:

Go to Settings → Usage & billing
-
Click View rates in the top right of the Phone numbers section

Rates vary by destination country and call type.
Monthly add-ons
Each phone number has a fixed monthly fee in addition to per-minute usage. This is listed separately under Monthly add-ons in your billing settings.
The fee depends on the country of the number and is shown before you buy it. Each number is billed for the full month, whether or not it takes a call. Spending limits don't apply to this fee. To stop it, open the Voice inbox settings and click Release number. The charge stops from the next billing cycle.
