A pricing model that charges per AI-resolved conversation (often $0.99 — $2.50 each) looks cheap at zero volume. The slope flips fast: 1,000 monthly resolutions land in the four-figure range before you've added the base platform seat fees. NovixAgent AI charges a flat monthly plan per website — your bill is the same however many conversations fit inside your plan's monthly message allowance (one question plus reply is one message). The trade-off is that cap instead of an open meter.
| Feature | NovixAgent AI | AI agents that charge per resolution |
|---|---|---|
| Billing model | Flat monthly plan per website ($29–$399/mo + Custom) | Per AI-resolved conversation + platform/seat fees |
| Bill at 100 conversations / month | $29/mo (Starter, 1,000 messages a month) | Low — $50-200 range typical |
| Bill at 1,000 conversations / month | $29/mo-$399/mo depending on how many messages each conversation takes (Starter 1,000, Pro 4,000, Business 20,000 messages a month) | $500-2,000 typical (per public pricing pages) |
| Bill at 10,000 conversations / month | $399/mo Business up to 20,000 messages, then optional message packs or Custom | $5,000+ typical |
| Trial mechanic | 7-day trial on Starter, Pro, and Business for a website's first subscription — card on file, no charge before day 8 | Free credits / capped trial, varies |
| Predictability | Same plan price every month within your tier (tax and any optional message pack aside) | Moves with traffic — finance/forecasting overhead |
| Risk on a viral spike | Hit cap → upgrade tier instantly, prorated | Bill auto-grows, no built-in ceiling |
| Cost of a declined / failed answer | Counts toward the monthly cap, declines included; returned when the AI call fails or the knowledge base is not ready | Varies — some platforms charge per attempt |
| Lead capture included | Every plan, first-class | Often separate add-on or seat |
| Voice (TTS) included | Pro / Business (150k chars / mo / 500k chars / mo) | Usually separate platform / add-on |
| Cancel anytime | Monthly billing available, no annual contract required | Often annual contract on the platform side |
At low volume, per-resolution pricing wins on absolute dollars. As soon as the agent does what you bought it to do — answer real visitor questions consistently — the flat plan tends to be both cheaper and easier to forecast. The break-even point varies, but for most teams it lands well below 1,000 conversations a month.

A flat plan keeps the plan price the same every month within your tier (tax and any optional message pack aside), while per-resolution pricing grows with each AI-resolved conversation, usually on top of platform or seat fees. NovixAgent AI charges a flat monthly plan per website ($29–$399/mo, plus Custom). The trade-off is your plan's monthly message cap instead of an open meter.
At low volume: if you only need a handful of AI-resolved conversations a month, paying per resolution can cost near zero. It also suits a finance team that prefers usage-based billing for cost-of-goods accounting, or a team already on a platform where the AI add-on is bundled with seat contracts. As volume grows the flat plan tends to be cheaper, until you reach your plan's monthly message cap.
On NovixAgent AI, reaching the cap means upgrading the tier, instantly and prorated; the bill does not grow on its own. A per-resolution bill grows automatically with no built-in ceiling.
On NovixAgent AI a message counts toward your plan's monthly cap as soon as it is accepted, including one the agent declines to answer; it is returned to the count when the AI call fails or your knowledge base is not ready. The plan price stays flat either way. Per-resolution platforms vary, and some charge per attempt.
No. Monthly billing is available with no annual contract, and Starter, Pro, and Business each come with a 7-day trial on a website's first subscription, with a card on file. Per-resolution platforms often carry an annual contract on the platform side.
