A: Hey Sumo-ling,

extra seats are billed according to our pricing, see here - https://www.ladesk.com/pricing

If you want to use different plan you will need to have all agents on that plan, so also those included in highest tier plan here on AppSumo, but you can benefit of paying less for additional agents.

If you don't use those features in All-Inclusive plan, you might save tome $ for tacos :)
