How to enforce a late fee or early bird discount
- Form Builder → Parts Bin → Add New → Package
- Label the late fee or early bird package (ie. $20 late fee or $-20 early bird discount)
- Set the min, max & default to 1 (this requires the package) → create an inventory item
- Drag the package onto the form layout
- Set the display between dates
- Save
Once the fee or discount has been added to the form layout, you can preview how this will appear on a specific date using the preview filters.
