Before you start
0 / 3
- Be the owner, or have a role with Manage billing
- A plan that sells it: seats on Plus or higher, numbers on WhatsApp and All-In-One, website chats on WebChat and All-In-One
- Your latest payment settled — buying is locked while one has failed or the plan is ending
Open Add-ons
Go to Settings → Billing & plans → Add-ons. Seats, WhatsApp numbers and Website chats each get a row showing what is in use, what the plan includes, what you bought and what is spare. A row your plan doesn't sell isn't shown. Seats can also be bought on Settings → Members, in the Seats card. The plan-limit window you meet when a number or chat runs out (Buy 1 more number, Buy 1 more widget) leads here too.

Choose how many
Select the Buy link on the row; it shows the price per month, or per year on a yearly plan. In the window, use the Bought stepper to set the total you want. It shows what the capacity becomes: what the plan includes plus what you bought.

Pins 2 and 3 and 4 are on the same screen.
Confirm the charge
The window says what the business pays: the change applies from today, pro-rated on your next invoice. Confirm with the Add button, which names what you are adding. A message confirms it.
Give some back
Step the number down and confirm with Remove and the count. The credit is pro-rated on your next invoice. You can't go below what is in use; the window says whether people, numbers or chats are holding them.
Add-ons end with your plan. While a payment has failed, or the plan is set to end, you can give some back but not add more.
If it doesn't work
| What you see | What to do |
|---|---|
| "Add-on seats aren't available on your current plan — upgrade to Plus to add members." | Extra seats start at Plus. Use Change plan. |
| "Your last payment didn't go through." above the rows | Update your card; nothing you already have is affected. See the last link below. |
| "Your plan cancels on" a date | Select Resume on Billing & plans, then add. |
| The minus button is greyed out | Something is using them. Make room first, for example remove a member or cancel an invitation. |
| "Couldn't update your capacity. Nothing has been charged." | Try again in a moment. |
