# Plans and top-ups

> Free credits to start, monthly plans, and top-ups that never expire.

Every workspace starts on Pay as you go with 500 free credits. After that, buy credits when you need them, or take a monthly plan for a lower price per credit.

| Plan | Price | Credits | Per credit |
| --- | --- | --- | --- |
| Pay as you go | Free | 500 once |  |
| Pro | $20 a month | 2,500 a month | 0.80¢ |
| Pro | $40 a month | 5,500 a month | 0.73¢ |
| Pro | $80 a month | 12,000 a month | 0.67¢ |
| Pro | $150 a month | 24,000 a month | 0.63¢ |
| Max | $250 a month | 42,000 a month | 0.60¢ |
| Max | $500 a month | 90,000 a month | 0.56¢ |
| Max | $1,000 a month | 190,000 a month | 0.53¢ |
| Max | $2,000 a month | 400,000 a month | 0.50¢ |

Change plan on the app's **Billing** page. There is no overage: when the credits run out, calls stop until you top up or the month renews.

## Plan credits and top-ups

- **Monthly plan credits** arrive each month and reset at renewal. The free credits on Pay as you go come once.
- **Top-ups** are one-off purchases of $10 to $500, at 100 credits a dollar. They never expire.
- Plan credits are spent first, then top-ups.

Billing can also top up for you when the balance drops below a threshold you choose. Turn on auto top-up on the Billing page.
