A: Thanks for pointing that out — here’s the official clarification:

✅ Basic Fields & Sections (unlocked in all paid tiers):

These include Date Range, Timers, and Milestone fields — plus document sections like Project Details and Milestones.

🔒 Pro Fields & Sections (available in higher tiers):

These include the Billing and Budget fields, as well as the Billing Schedule section in documents.

So yes — the Billing field is a Pro feature, and it requires a higher tier. If you saw a “Basic” upsell during your trial, that may have been due to temporary free access or an older label.
