Items

Manage your catalog of products and services to reuse on invoices and quotes.

Overview

The catalog stores reusable products and services so you can drop them into invoices and quotes without retyping name, price, unit, or tax rate. Items are scoped to a specific company.

Each item has an auto-generated item_code (e.g. SER-000001) that you can override when creating it.

Create an Item

 1curl -X POST "https://api.corebill.io/v1/items" \
 2  -H "Authorization: Bearer sk_live_your_api_key" \
 3  -H "Content-Type: application/json" \
 4  -d '{
 5    "name": "Web Development",
 6    "description": "Frontend implementation",
 7    "unit": "hour",
 8    "unit_price": 75,
 9    "currency": "USD",
10    "item_type": "service",
11    "tax_rate": 16,
12    "category": "Development"
13  }'

Only name and unit_price are required.

All monetary amounts are in the major unit of the currency with 2 decimals (major unit, 2 decimals). $1,234.56 is represented as 1234.56, never as cents (123456). unit_price: 75.5 means $75.50 USD.

Delete an Item

Deleting an item is a soft delete (sets deleted_at and is_active = false). Existing invoices and quotes that reference it keep their line item snapshot intact. Requires admin permission.

 1curl -X DELETE "https://api.corebill.io/v1/items/itm_abc123" \
 2  -H "Authorization: Bearer sk_live_your_api_key"
