Item Fields

Item fields are the building bricks of Advik Booking. Every question your customer is asked on the booking form is an item field. Define them once, attach them to any service, and they automatically drive price and duration.

Where to find it

Advik Booking → Services → Item Fields. Or open a service and click Add Fields — both lead to the same library.

Field types

Creating a field — step by step

1. Open the field library
   Go to Advik Booking → Services → Item Fields and click Add Field.
2. Choose a label and key
   Label is what the customer sees. Field key is the internal machine name (auto-generated from the label; you can change it). Once saved, the key cannot be renamed without breaking integrations — choose carefully.
3. Pick a field type
   See the table above. Changing the type after creation requires re-entering the options.
4. Add choices (dropdown / radio / checkbox only)
   Each choice has a label, an optional price modifier, and an optional duration modifier. Leave both blank for choices that don't change the price.
5. Set price per unit (number fields only)
   For stepper fields, set a base price-per-unit. Example: $15 per bedroom. The customer's quote updates live as they change the value.
6. Set duration per unit (optional)
   The total booking duration is base_duration + (field_value × duration_per_unit). Example: 30 minutes base + 15 min per bedroom.
7. Set validation
   Mark required, set min/max, and any regex for text fields.
8. Save and attach to services
   Once saved, the field is in the library. Open any service and toggle it on in the Fields panel.

Anatomy of a field

Reusing a field across services

The Number of bedrooms field with price_per_unit = $15 is attached to:

• Standard Clean (1–6 hours)
• Deep Clean (2–8 hours)
• End-of-Tenancy Clean (3–10 hours)

Change price_per_unit from $15 to $18 once, and all three services reprice instantly.

Per-service price overrides

If a single service needs to charge a different price per unit (e.g. Deep Clean charges $20 per bedroom, not the library default of $15), you can override it from the service edit screen.

The override is stored on the service-field link, not on the field itself, so other services are unaffected.

Field groups

Group related fields together to keep the admin tidy. Example group: Property details with Number of bedrooms, Number of bathrooms, Square footage. Groups don't affect the front-end form layout.

Common patterns

Yes / No add-on question

Use a single-choice radio or a checkbox field with two options. Price goes on the "Yes" option. Example: Include laundry? with Yes +$25 and No +$0.

Quantity with price-per-unit

Use a stepper field. Set price_per_unit. The customer changes the number; the price updates live. Example: Number of windows to clean at $4 per window.

Choose one of many variants

Use a dropdown or radio. Each option can have its own price modifier. Example: Property type with Studio +$0, Flat +$10, House +$25.

Conditional question

Add the field to an add-on rather than a service. The field will only appear when the customer selects that add-on. Example: Type of mattress only when Mattress cleaning is selected.
