How will the billing change when we add more people in the team?
You can invite as many new teammates as you need, there is really no limit to it. One credit card is required per team and this credit card is charged. If you are the team owner or admin you can set up the payments directly in the product. The billing period for a new member starts when they’ve signed up for the service. The change for them will be added to the next billing period if it’s a monthly plan or charged within a few days if it’s a yearly subscription.
