Three pricing models on the market

Package: a monthly price with included minutes; further minutes cost extra. This is how Call0 bills.

Custom: the price is in the contract, usually for large volumes and after a sales call.

Frequently asked questions

What does an AI phone assistant cost at Call0?

Launch costs €110 per month or €1,188 per year and includes 700 call minutes. All prices are net, plus VAT.

What happens when the included minutes are used up?

The assistant keeps answering calls. Depending on the plan, each additional minute costs €0.16, €0.14, €0.12.

Does the phone number cost extra?

Every paid plan includes at least one number. Each additional number costs €15 per month. You can also forward your existing number.

Can I test for free beforehand?

Yes. The Free plan includes 15 test minutes, without a credit card and without a phone number. Every paid plan also includes 30 browser test minutes per month.

Is annual payment worth it?

With annual payment you pay the annual amount in advance and save at least 1 monthly fee compared with 12 monthly fees. Monthly payment can be cancelled monthly.

Why are per-minute prices hard to compare?

Some providers state a package price that covers everything, others only a platform fee and bill the language model and telephony separately. So always compare the monthly total for your call volume.

What does the email assistant cost?

The email assistant has plans of its own: Launch €89, Growth €220, Scale €550 per month; with yearly billing €79, €199, €499 per month. All prices exclude VAT. Launch: 500 emails per month, 1 mailbox. Growth: 2,000 emails per month, 3 mailboxes. Scale: 6,000 emails per month, 10 mailboxes. Every email the assistant answers, drafts or sorts counts; observing alone does not. Once the allowance is used up, the assistant pauses until the next contract month or until you change the plan. During the pause emails stay untouched and unread in the mailbox; afterwards the assistant handles only emails of the last 24 hours and no longer answers older ones. There are no extra charges.
