What an add-on is
An add-on is an extra service that is sold together with a main service, such as Radon Testing, Sewer Scope or WDO / Termite Inspection on top of a Home Inspection.- Every add-on belongs to one main service. It is offered only when that main service is on the inspection.
- An inspection has one main service. Everything else on the same inspection is an add-on of that service. See Main services vs add-on services.
- An add-on has its own price and time, and can bring its own templates, agreements and price modifiers.
- by your team, when scheduling in the dashboard
- by the client, when booking on your online scheduler or getting a price from your quote widget
- by the client after booking, from the inspection review link or the client portal, if you allow it
Add an add-on to a service
Open the main service
Click Add Add-On

Allow Upselling and Hide from Scheduler
These two options control where the add-on is offered. They are independent: you can turn on both, one or neither.- Hide from Scheduler only affects the online scheduler and the quote widget. If every add-on of a service is hidden, the add-on step of the scheduler is skipped for that service.
- Allow Upselling is what lets clients add the add-on after the inspection is created. An add-on that is hidden from the scheduler but allows upselling can’t be picked while booking, but the client can still add it later from the review link or the client portal.
- Add-on upsell emails list every add-on the client hasn’t added yet, whatever these two options say. The link in those emails opens the review link, which only offers add-ons with Allow Upselling on. Turn on Allow Upselling for every add-on you promote by email.
Add-on price and time
- Price: the add-on’s Add Fees is added to the price of the inspection.
- Time: its Add Hours is added to the length of the inspection on the calendar.
- Add-on modifiers: an add-on can have its own modifiers, of any type: square feet, age, distance, foundation, day, time or custom fields. They apply only when the add-on is on the inspection. For example, “Radon Testing: $50 for each unit after the first”. See Modifiers on add-ons.
- Tax: add-ons have no tax of their own. The taxes of the main service are charged on the whole order, add-ons included. See Sales tax.
- Discount codes: a code can be limited to particular add-ons. See Discount codes.
Templates and agreements
When an add-on with templates or agreements is added to an inspection, those templates and agreements are added to the inspection too, unless they are already on it. This happens in the dashboard, on online bookings, and when a client adds the add-on from the review link or the client portal. Removing the add-on later doesn’t remove its templates or agreements. A report started or an agreement already sent stays on the inspection. To remove one, do it from the inspection.Add add-ons to an inspection

- Online scheduler
- Review link
- Client portal

- + (Add another) adds one more of the same add-on. See Quantity.
- − (Decrease quantity) takes one away. At a quantity of 1 the button is an X (Remove add-on).

Lock client order changes
To stop clients from adding or removing add-ons themselves once an inspection is booked, go to Org Settings → Business Management → Client Order Changes and turn on Lock services and add-ons after booking. It is off by default.
- It applies to existing and new inspections as soon as you save.
- Clients can still pick add-ons on a proposal they haven’t accepted yet.
- Your team can always change the order from the dashboard.
Quantity
In the dashboard, the same add-on can be added more than once, for example two radon monitors. Click + on the add-on’s row, or pick it again from Add Add-on.- The line shows the quantity, such as Radon Testing × 2, and the price and hours are multiplied: 2 × $150 = $300.
- The add-on’s modifiers are multiplied by the quantity too.
- Changing the quantity clears any price, name or hours you typed for that add-on’s lines with Edit Price or Duration.
- The add-on’s templates and agreements are added once, not once for each.
Use the same add-on on several services
An add-on belongs to one service. To offer the same add-on with other services, copy it. Each copy is separate: changing one doesn’t change the others.- Add from Another Service
- Duplicate
- Move

Reorder, edit or delete an add-on
- Reorder: drag an add-on by its handle. Add-ons are listed in this order in the dashboard, on the online scheduler and for clients.
- Edit: click the pencil icon. Inspections that already have the add-on keep the name and price they were booked with on their pricing lines.
- Delete: click the trash icon and confirm. The add-on and its modifiers are deleted and can’t be brought back.
What clients see
- Online scheduler and quote widget: each add-on with its description and its price, rounded to the whole dollar.
- Review link and invoice: each add-on as its own line, with its modifiers included in its price.
- Client portal: the add-ons on the order under Order Details.
