Configure PayPal in Payment Settings and send line items directly from the calculator.

## Set up
1) Edit your calculator → **Payment Settings** → check **PayPal**.
2) Enter your **PayPal email/details**, then **Save**.
3) If you use coupons or Fee & Discount Adjuster, check **Combine all line items into one item** so discounts are honored.

## Notes / limits
- PayPal cannot receive file uploads or custom fields from SCC.
- Avoid negative line items; use the combine option for discounts.
- Test after saving to confirm the button renders.
