What counts as a message?
Each AI-generated response sent to a visitor counts as one message against your monthly quota. Visitor messages themselves — what your customers type — do not count. If a visitor asks three questions and your agent answers each one, that consumes three messages.14-day free trial
All paid plans (Starter, Pro, Business) start with a 14-day free trial. You are not charged until day 15, and no credit card is required to begin. If you cancel before day 15, you owe nothing.
Upgrading and downgrading
When you upgrade your plan, the change takes effect immediately and your billing is prorated for the remainder of the current cycle. You gain access to higher message limits, additional agents, and any new features right away. When you downgrade, the change is scheduled for the end of your current billing cycle. You retain your existing plan’s features and limits until that date, at which point the lower-tier plan activates.Exceeding your message limit
If your workspace reaches its monthly message limit before the billing period resets, outgoing AI responses are throttled. Visitor messages will no longer receive AI replies until either the new billing period begins or you upgrade to a higher plan. Upgrading restores service immediately.Payment methods
- Standalone (Stripe)
- Shopify Admin Billing
If you signed up directly at merchantai.io, your workspace uses Stripe for payment processing. You can add, update, or remove a payment method from the Billing section of your account settings at any time.
