Per Seat Billing

Pro starts at $8.75/user/month or $7.25 billed annually.

The current pricing page is seat-based. The number in the old template was too high for today's public Pro plan.

Slack's public pricing is a straightforward collaboration seat ladder with a discount for annual billing.

Implementation

This snippet is the closest Owostack implementation of the live pricing shape above. It is not a literal copy of the vendor's internal billing system.

const seats = entity("seats", {
  name: "Seats",
});

plan("team", {
  name: "Team",
  price: 0,
  autoEnable: true,
  currency: "USD",
  interval: "monthly",
  features: [seats.limit(5, { overage: "block" })],
});

Rules

Slack's public pricing is explicitly per-user.

Annual billing lowers the effective monthly seat price.

The Owostack snippet below models the seat-based shape, not Slack's entire packaging matrix.
