# Billing

> Plans, email allowances, prepaid credit, and number rentals.

Manage your plan and prepaid balance under **Billing** in the dashboard. The workspace owner controls checkout, plan changes, and automatic top-ups.

## Plans

| Plan | Monthly price | Inboxes | Recipient emails per month | Attachment storage | Members |
| - | -: | -: | -: | -: | -: |
| Free | \$0 | 3 | 3,000 | 3 GB | 1 |
| Developer | \$20 | 10 | 10,000 | 10 GB | 2 |
| Scale | \$200 | 150 | 100,000 | 100 GB | 10 |

Prices are USD before applicable taxes. See [pricing](https://www.papers.bot/pricing) for current offers. Custom domains are not yet available in self-service.

## Email usage

Email allowances count recipient emails, including incoming deliveries. Sending one message to several recipients consumes multiple units. Outgoing usage is counted when the provider accepts the message; pending sends reserve allowance.

Paid allowances follow the subscription period. Free allowances follow UTC calendar months. Unused included email allowance does not roll over. Funded overages cost \$0.002 per recipient email.

If the allowance is exhausted and no funded overage is available, additional incoming mail is not stored. Attachment storage has its own plan allowance.

## Prepaid credit

Add $10, $25, $50, or $100 for messaging charges and email overages. Unused purchased credit carries forward. Pending sends can reserve funds, so the amount available for new work may be lower than the total balance.

Automatic top-ups are optional. The owner chooses a threshold, top-up amount, and monthly ceiling. Failed payments can disable automatic top-ups until the payment issue is resolved and the owner opts in again.

## Phone rentals and SMS

Standard US numbers cost \$3 per month each, separately from the workspace plan. Developer supports up to 3 numbers; Scale supports up to 25. Free does not include number rentals. Select a number in the dashboard before checkout.

SMS charges use prepaid credit and vary by destination and segment count. Both incoming and outgoing messaging can incur charges. The first successfully paid number rental grants \$0.50 of messaging credit once per workspace.

## Change or cancel a plan

Upgrades are prorated and take effect after successful payment. Downgrades are scheduled for renewal. Cancellation stops future renewals. Existing resources are retained if a lower plan reduces capacity, but additional activity can be blocked until usage fits the plan.

Number rentals have a separate lifecycle. Read [number release and cancellation](https://www.papers.bot/docs/phone/numbers.md#release-a-number) before cancelling a rental.
