What are add-ons?
Add-ons are optional extensions that unlock industry-specific features beyond the core File Approved workflow. They require an active Pro plan and are billed as separate line items on your subscription.
You can enable or disable add-ons at any time from Settings. Charges are prorated immediately, you only pay for the time you use them.
Current add-ons: Engineering & Architecture ($29/mo). More add-ons are coming.
