How much does an AI sales agent cost?

How the pricing works

Instead of charging per seat or per agent, Port8 bills on AI answers. Every plan comes with a monthly allowance of AI answers and a set number of assistants. Every plan starts with a 30-day money-back guarantee.

What counts as 1 AI answer?

One message the agent answers. That is the entire billable surface. Everything the agent does around an answer is included, so there is no second meter to read and no per-action rate to model:

The rate does not move with the channel either. An answer costs the same in site chat, in your bio link, in WhatsApp, in Instagram DM, and in Messenger. Turning on another channel gives the agent more places to sell, not another price to look up.

The ecommerce plans

We do not list the monthly dollar price of Starter, Growth, and Scale here, because plan pricing can change. For the current plan pricing, see the Port8 pricing page.

There are also creator plans for individual creators and personal brands, on the same single unit: Micro at 100 AI answers, Macro at 250, and Mega at 500 per month. The overage rate of $0.10 per AI answer and the 30-day money-back guarantee apply across the board.

What drives the cost

With usage-based pricing, the bill is not one fixed number. Here is what moves it:

• Conversation volume. More shopper messages answered means more AI answers used. A store with light traffic sits well inside its plan allowance. A high-traffic store works through the allowance faster and is more likely to hit overage.
• Number of assistants or brands. Each plan tier includes a set number of assistants (1 on Starter, 3 on Growth, 5 on Scale). If you run multiple brands or storefronts, you need a tier that covers them.
• Overage. Once you pass your monthly allowance, additional answers are billed at $0.10 each. If you are regularly in overage, moving up a plan usually buys a larger allowance for less than the per-answer rate.
• Shopify connector. Every connected Shopify shop adds $19 per month. Multi-store Shopify brands should count this into the monthly number.

What does not move it: the channel a conversation happens on, and how much work the agent takes on inside a conversation. A chat where the agent answers twice, builds a cart, and tracks an order bills two AI answers, exactly like a chat with two plain questions in it.

The practical takeaway: pick the plan whose answer allowance roughly matches your monthly conversation volume, and let overage cover the spikes.

Does it pay for itself?

We are not going to promise a specific ROI, because it depends on your traffic, your margins, and your catalog. Anyone quoting you a guaranteed return on an AI agent is guessing.

Here is the scoped, honest version of our own number: Port8 stores see a sourced +15-30% conversion lift on chat-engaged sessions. That is our product's measured effect on the shoppers who actually engage with the agent. It is not an industry-wide guarantee, and it is not a promise that your total store revenue moves by that amount. We keep the claim narrow on purpose.

To frame cost against value: a usage-based plan means you are paying in proportion to how many shoppers the agent is helping. If the agent is busy, you are running a lot of conversations, which is the situation where a conversion lift is worth the most. For more on why that lift exists in the first place, see why your store converts 2% when a real shop converts 20%.

The short answer

An AI sales agent for ecommerce is priced as a monthly plan plus usage. With Port8, the usage is one number: AI answers. You get an allowance per plan, $0.10 per answer beyond it, the same rate on every channel, and a 30-day money-back guarantee to test it on real shoppers first. Match the plan to your volume, and spend only scales as the agent scales the work it does. See Port8 for ecommerce for what the agent actually does on your storefront.
