Is there a monthly spending cap?

Yes. Usage charges are capped at $5,000 for each 30-day billing period starting when you accept billing. The cap is part of the Shopify usage billing subscription, so merchants have a predictable upper limit even if conversation volume spikes. Most stores will be far below the cap; it is mainly a safety limit for unusually high volume.

Cap amount and billing period

The limit applies to usage charges, not to every possible app interaction.

• Maximum $5,000 in usage charges per 30-day billing period.
• The period starts when you accept billing—track it from acceptance, not from an arbitrary calendar month if those differ.

At $0.99 per AI resolution, the cap bounds how many charged AI-resolved segments can accumulate in a single period before additional AI-resolved closes in that period are not charged.

How the cap fits Shopify billing

Simple Chat’s usage model runs through Shopify billing in USD.

• The $5,000 cap is embedded in the Shopify usage billing subscription.
• Merchants get a predictable upper limit on usage charges during spikes.
• If the cap is reached, Simple Chat can continue resolving conversations, but additional AI-resolved closes in that billing period are not charged.

Service can continue for customers while usage charges for that period stop growing after the cap.

What happens for most merchants

Most stores will be far below the cap in ordinary operation.

• The cap targets unusually high volume, not typical support loads.
• Day-to-day AI-resolved volume for most merchants will not approach $5,000 in usage charges every 30 days.

Use the cap for worst-case budgeting, not as a forecast of what you will spend each period.

What counts toward paid usage

Only certain closes increase usage charges.

• AI resolution segments count as paid usage at $0.99 each.
• Segments need at least one customer-visible AI reply, no customer-visible staff reply since open or last reopen, and an AI close.
• Internal notes, staff-only investigation, and background tool usage do not by themselves make a segment staff-resolved; a customer-visible staff message does.

Conversations that are not AI-resolved under those rules do not add to paid usage, which also affects how quickly you approach the cap.
