Invoice model
Invoice model controls how teams automate invoice data extraction before routing results into approvals, ERP systems, payment workflows, audits, or exception handling queues. Teams see it in document intelligence studio, prebuilt invoice api calls. It is not a custom document model, a receipt model, an invoice section in billing, an accounting system, or a generative model that summarizes documents; confusing them can create incorrect payment amounts, missed line items. Use the term when reviewing access, monitoring, cost, recovery, or performance. It keeps architects, operators, security reviewers, and support teams focused on the same setting, resource, or behavior.

Prebuilt document model
A prebuilt document model is a ready-made Document Intelligence model for a common document type such as an invoice, receipt, ID document, contract, bank statement, pay stub, or tax form. Instead of collecting labeled examples and training a custom model, a developer calls the prebuilt model and receives extracted fields, text, tables, confidence scores, and layout information. It is useful when the document matches a known pattern well enough. It is not magic; teams still need validation, exception handling, data protection, and downstream business rules.
