Add-ons

An add-on is a chargeable extra attached to a booking - equipment, catering, staffing, a hire item. It appears as its own line on the invoice.

Add-ons are configured under Clients & Services before you can put one on a booking. There are three levels, and you only need to think about the top two once.

LevelWhat it isExample
Add-on Group TypeThe broadest splitCatering
Add-on GroupA set within thatDrinks
Add-onThe thing you actually charge forCola
The add-on detail panel with Add-on Name reading Cola, Add-on Group reading Drinks, a Unit Cost of £0.65, a Tax Rate of UKBEVERAGES, a ticked Portal Visible checkbox and an empty Notes field.

One add-on. The price here is the price of a single unit - what that means on a session booking is the one thing worth reading twice, below.

An add-on group carries a name, its group type and notes. An add-on carries:

FieldWhat it does
Add-on NameWhat staff pick from the list
Add-on GroupWhich group it belongs to
Unit CostThe price of one
Tax RateWhich rate applies to it
Portal VisibleWhether your customers can see and choose it when booking themselves
NotesFree text for your own reference

Portal Visible is worth a thought per add-on. Something that needs a conversation first - staffing, a bespoke setup - is better left off the portal.

Add-ons is the button at the top of the booking panel. It carries a count once you have picked some, so you can see at a glance that a booking has extras on it without opening anything.

The ADD ADD-ON panel with three dropdowns reading Catering, Drinks and Cola, an Add button, and a grid listing Cola with a quantity of 1, an unticked Recur checkbox and a total of £0.65. A blue tip below reads: Each add-on is charged individually to every attendee booked into this session.

Adding Cola to a session booking. The tip at the foot only appears on sessions, and it is the whole of the per-attendee rule in one sentence.

Work down the three dropdowns - Add-On Group Type, then Add-On Group, then Add-On - and choose Add. Each choice narrows the next, which is what the grouping is for.

The grid below lists what you have added:

Column
NameThe add-on
QtyHow many. Type straight into it
RecurWhether it comes along to the other dates of a series
TotalWhat it comes to
×Removes it from the booking

This is the one that produces surprises on invoices.

What the price means
Space bookingThe total. £20 of catering is £20, on the client’s invoice
Session bookingThe price one person pays. £0.50 on a session with four attendees is £2.00, split across four invoices

On a session the panel says so itself - the app shows “£0.50 each × 4 attendees” and a tip reading “Each add-on is charged individually to every attendee booked into this session.”

So enter what one person pays and let Axiom do the multiplication. Entering the total is the mistake to avoid, and it scales with the size of the class.

That follows from how the two modules bill: a space booking charges one client, a session booking charges every attendee individually. See making a session booking.

Recur is unticked by default. An add-on you add sits on the date in front of you and no other.

If the booking repeats and the extra is needed every week, tick it. If it is a one-off - a projector for the first session only - leave it.

Attendees work the same way and have their own Recur tick, for the same reason. See repeating a booking.

Add-ons are their own lines, separate from the booking charge and from any booking-type set fee, each carrying the tax rate you gave it.

If a booking is later cancelled, its add-on lines are removed or credited along with it - see editing and cancelling.
