Add-ons

Build a catalog of priced add-ons couples can select; the total rolls into their amount due and is paid with your existing handles.

Add-ons are optional, priced upgrades a couple can add to their package: a photo booth, an extra hour, uplighting, a second speaker. You define the catalog once; each couple picks what they want on their event. The selected total simply rolls into the amount they already owe and is paid the same way as everything else. No card processor is involved. spinbook never sits between you and your money.

Build your catalog

Go to Settings → Add-ons and add each upgrade with a name, an optional description, and a price. You can:

• Deactivate an add-on to stop offering it. Couples can no longer select it, but anyone who already added it keeps it (their price is locked in).
• Delete an add-on entirely. Couples who already selected it keep the item on their total, because the name and price are snapshotted at selection time.

How couples select add-ons

Every event's portal gets an optional "Add-Ons (Optional)" checklist item that opens the couple's Add-ons page. There they tick the upgrades they want, set a quantity, and see a running subtotal, then hit Confirm selections.

Because prices are snapshotted when they confirm, editing a catalog price later never silently changes a total someone already agreed to.

How add-ons affect the amount due

A confirmed add-on is money owed, so it's added on top of the event's quoted total:

Amount due = quoted total + selected add-ons − payments received

This shows up on the Payments page as an "add-ons +$X" line under the quoted total, and it flows into the couple's Amount due panel. Adding an add-on re-opens the Remaining Balance checklist item until the new total is paid in full. Everything stays consistent with what's actually owed.

Add-ons even work before you've set a quoted total: if a couple selects a $450 photo booth on an event with no quote yet, their amount due shows $450.

The checklist item is always optional

The "Add-Ons (Optional)" item never blocks a couple's progress. It has no due date, and it completes the moment they confirm, even if they select nothing. It's there to invite upgrades, not to nag. See Checklists & forms for how bound checklist items derive their done-state automatically.

Checklist

• Add your upgrades in Settings → Add-ons (name, description, price)
• Deactivate anything you're not currently offering
• Point couples to their Add-ons page (it's already on their checklist)
• Confirm the total on the Payments page reflects selected add-ons
