Add-ons are optional extras players can buy during registration — a classic way to boost fundraising. Common ones:
- Mulligan packages ("3 mulligans for $20")
- Putting or closest-to-the-pin contest entries
- Extra banquet/dinner tickets
- String or "throw" packages
Set them up in the event builder under Add-ons with a name and price. They appear at checkout and the revenue is tracked separately.
