Pricing transparency is the reason most sales teams try AI calling and then abandon it. The sticker price looks fine, and then the invoice arrives with per-minute LLM fees, voice engine charges, transcription surcharges, and a monthly platform fee on top.

Kolz Bulk is priced the opposite way: one flat rate, one number, nothing hidden.

The short version

$0.03 per minute. Flat. All-inclusive.

That single number covers the AI voice agent, the language model, speech-to-text, the voice, the call, and the platform. There are no monthly subscriptions, no seat licenses, no integration fees, and no per-call markup. You pay for exactly the minutes you dial.

New accounts get 100 free minutes with full functionality, no credit card required. You can run a real campaign, listen to the recordings, and read the scored lead sheet before you spend a rupee, a dollar, or an euro.

What $0.03/minute actually includes

The AI voice agent that runs the conversation, handles objections, and follows your call script.
The full voice stack: speech recognition, language model, and voice synthesis. Every component is bundled.
Call infrastructure and the dialer.
The platform: campaign setup, live monitoring, and delivery of results.
The Excel-In, Excel-Out workflow: upload your list, launch, and download an enriched spreadsheet with call status, lead scores (Hot/Warm/Cold), conversation summaries, and recording links.
30+ language support and pre-built sales templates, at no extra cost.

There is no line item for "AI tokens" or "voice minutes" beyond the $0.03. The price you see is the price you pay.

Why other platforms cost more than they look

Developer-focused voice platforms charge a base rate (often around $0.05/minute) and then bill you separately for each connected provider: the speech-to-text engine, the LLM you chose, and the text-to-speech vendor. Assemble the full stack and a single minute of an AI call can cost $0.08 to $0.12 or more, depending on the models you pick.

That model makes sense for engineering teams building custom agents. For a sales team that just wants to call 1,000 leads, it means unpredictable invoices and a lot of assembly work before the first call goes out.

Kolz Bulk replaces that assembly with one flat number. $0.03/minute is cheaper than the base rate of most API stacks, before their add-ons even appear on the bill.

How the free minutes work

Every new Kolz Bulk account starts with 100 free minutes. You get:

Full access to all features, not a crippled trial.
Real calls to your real leads.
The complete scored Excel output, recordings, and summaries.

No credit card is required to start. When the free minutes run out, you add credit and pay as you go. If you stop using it, you stop paying. There is no monthly fee waiting for you.

Who it suits best

Because pricing is usage-based, Kolz Bulk scales with teams that actually make calls:

Real estate brokers working 1,000-property lists.
Insurance and Medicare agents qualifying high-volume lead feeds.
Staffing agencies doing candidate outreach.
MCA and business-loan brokers working merchant lists.
Lead-gen agencies running campaigns for multiple clients.

A campaign that costs under $30 for 1,000 minutes of calling is a different business conversation than a platform that bills a monthly subscription before you have made a single call.
