}Create advance invoice with pre-calculated totals
/advance-invoices/customCreate an advance invoice with pre-calculated totals from an external system.
The caller provides total, total_with_tax, and taxes at the document level, and total/total_with_tax on each line item.
All other logic (numbering, fiscalization, customer handling, payments, lifecycle hooks) is identical to the standard create endpoint.
Header parameters
Entity ID on which the request is made. Auto-selected when only one entity exists, required when multiple entities exist.
Body parameters
Document due date in YYYY-MM-DD format
Referenced Customer ID.
Pre-calculated document total (before tax).

}List all advance invoices
/advance-invoicesRetrieve a paginated list of advance invoices with optional filtering and sorting. Supports cursor-based pagination, JSON querying with MongoDB-style operators, full-text search, and sorting.
Header parameters
Entity ID on which the request is made. Auto-selected when only one entity exists, required when multiple entities exist.
Query parameters
Number of results per request.
Default: 10
Opaque cursor to fetch the next page of results. Reuse only with the same effective ordering. Use the value from pagination.next_cursor in the previous response.
Opaque cursor to fetch the previous page of results. Reuse only with the same effective ordering. Use the value from pagination.prev_cursor in the previous response.
Whether to include the total count of items in pagination.total.
Default is true.
When false, pagination.total returns -1 for better performance.
Sort by one field or provide a repeated array for multi-column ordering. Prefix a field with - for descending order. When paginating, reuse cursors only with the same effective ordering.
JSON query object for filtering results. Supports MongoDB-style operators.
Supported operators:
- equals or direct value - Exact match (default)
- gte - Greater than or equal
- lte - Less than or equal
- gt - Greater than
- lt - Less than
- in - Value in array
- notIn - Value not in array
- contains - String contains (case-insensitive)
- startsWith - String starts with
- endsWith - String ends with
- between - Value between two numbers/dates [min, max]
Allowed fields: id, number, date, customer, customer.name, customer.email, customer.address, customer.city, customer.country, total, total_with_tax, items.name, items.description, payments.type, payments.date, document_relations.relation_type, document_relations.target_type, metadata, created_at, updated_at, paid_in_full, voided_at, paid_in_full, voided_at
Examples:
- {"total": {"gte": 1000}} - Invoices over 1000
- {"customer.name": {"contains": "Acme"}} - Customer name contains "Acme"
- {"date": {"between": ["2025-01-01", "2025-12-31"]}} - Date range
Full-text search query to filter results across multiple fields.
Searches are case-insensitive and match partial strings.
Searches across all text fields including names, descriptions, addresses, and metadata values.
Comma-separated list of relations to include in the response.
Available relations:
- payments - Payment records linked to this advance invoice
- document_relations - Linked documents (invoices, credit notes, etc.)
Usage:?include=payments?include=payments,document_relations
When true, returns only soft-deleted (trashed) items. Default false excludes deleted items.
