What is Microsoft Syntex / SharePoint Premium?

Microsoft Syntex (now integrated into SharePoint Premium) uses AI and machine learning to automate document processing at enterprise scale. When documents are uploaded to SharePoint, Syntex models automatically classify the document type, extract key metadata fields (dates, amounts, names, contract terms), apply retention labels and sensitivity labels, and make the content searchable and actionable.

This transforms SharePoint from a passive file repository into an intelligent content platform.

AI model types and capabilities

SharePoint Premium provides four distinct AI model types. Each is optimized for different document structures and processing requirements.

Prebuilt models (no training required)

Prebuilt models are production-ready AI models from Microsoft that process common document types with no training or configuration. Simply enable the model on a SharePoint library and it begins extracting data immediately.

Available prebuilt models:

• Invoice processing: Extracts vendor name, invoice number, date, due date, total amount, line items, PO number, and billing address. Accuracy: 92–98% on standard invoice formats. Processes PDF, TIFF, and image formats.
• Receipt processing: Extracts merchant name, date, total, subtotal, tax, payment method, and line items. Ideal for expense report automation.
• ID document processing: Extracts name, date of birth, address, and ID number from driver's licenses, passports, and government-issued IDs.
• W-2 and 1099 processing: Extracts all standard fields from US tax forms for HR and finance automation.
• Business card processing: Extracts contact information for CRM integration.

Teaching method (custom semi-structured models)

The teaching method is the most versatile custom model type. You train the model by uploading 5+ example documents and labeling the fields you want to extract. The model learns the document structure and applies extraction rules to new documents automatically.

• How it works: Upload example files (PDF, Word, images) to the content center. Label each field by highlighting the text in the document. Train the model and review confidence scores. Publish the model to one or more SharePoint libraries.
• Best for: Contracts, proposals, applications, medical records, and semi-structured documents where fields appear in predictable locations but with varying layouts.
• Accuracy range: 85–96% depending on document consistency.

Freeform selection method (unstructured documents)

Describe the field in natural language: "Extract the total contract value mentioned in the agreement." The AI model interprets the document content and extracts the requested information. No labeled training examples are required.

• Best for: Letters, memos, meeting notes, research reports, and other unstructured documents where information appears in narrative form rather than structured fields.
• Accuracy range: 80–92%. Lower ceiling than the teaching method but handles a much wider variety of document formats.

Layout method (structured forms)

The layout method is optimized for documents with fixed, predictable layouts — government forms, standardized applications, inspection checklists, and survey forms.

• Accuracy range: 90–97% for well-formatted forms with clear field boundaries and legible text.
• Best for: Any document with a fixed layout where field positions are consistent across all instances.

Model training best practices

Training set composition

• Include at least 50 representative examples — not just the minimum 5. Cover all document variations: different vendors, layouts, languages, scan qualities, and edge cases.
• Include 10–15% "negative examples" — documents that should NOT be classified as this type — to reduce false positives.
• Establish labeling guidelines before training begins. Define exactly where each field starts and ends, how to handle multi-line values, and how to label fields that are sometimes missing.
• Inconsistent labeling is the number one cause of low model accuracy.

Do not skip the pilot

Before deploying a model to a production document library, run a pilot with 200–500 real documents from the past 3 months. Review the model's predictions manually for the first 100 documents. Identify and retrain on any systematic errors before they affect production data quality.

Content assembly and document generation

Content assembly generates documents from templates with data merged from business systems. It is the reverse of document processing: instead of extracting data from documents, it inserts data into document templates.

Enterprise content assembly use cases

• Contract generation: Automatically populate contract templates with client data from CRM systems, generating review-ready agreements in seconds instead of hours
• Proposal creation: Merge project scope, pricing, and terms from multiple data sources into professional proposals
• Patient letters: Create personalized patient communications by merging medical record data into approved letter templates while maintaining HIPAA compliance
• Onboarding packets: Assemble employee onboarding document sets with pre-populated personal information from HR systems
• Compliance reports: Generate regulatory filings by pulling data from governance systems and populating standardized report templates

Compliance and governance

All document processing occurs within the Microsoft 365 compliance boundary under your Business Associate Agreement (BAA). This is a non-negotiable requirement for healthcare, financial services, and government organizations.

• Sensitivity labels are automatically applied to documents containing PHI or classified content
• Audit logs capture every document processing event for compliance reporting
• Retention policies enforce regulatory minimum retention periods automatically
• Processing occurs entirely within your tenant — no document content leaves your Microsoft 365 environment

ROI analysis and business impact

Accounts payable automation

Invoice processing with Syntex achieves 95%+ extraction accuracy on vendor name, invoice number, date, due date, and total amount. A 1,000-invoice-per-month organization saves 200+ hours of manual data entry. At a fully loaded cost of $75/hour, that is $15,000/month in labor savings — a 10x ROI on Syntex licensing costs.

Contract management

Teaching models extract parties, effective dates, expiration dates, and contract values from executed contracts. A legal team processing 500 contracts per month saves 150+ hours of manual review time. Metadata extraction lets contract management systems trigger automated renewal alerts and compliance reviews.

Healthcare document processing

Healthcare organizations process patient intake forms, referral letters, prior authorization requests, and clinical trial documents. Syntex extracts patient demographics, diagnoses, procedure codes, and insurance information. This removes data entry from clinical workflows and reduces errors in downstream systems.

Frequently asked questions

What is the difference between Microsoft Syntex and SharePoint Premium?

Microsoft Syntex was rebranded as SharePoint Premium in 2024. SharePoint Premium includes all Syntex capabilities plus additional features including eSignature, content assembly, and advanced content management. The underlying AI document processing models and licensing model remain the same.

How many training examples do I need for a custom model?

The minimum is 5 example documents, but EPC Group consistently achieves higher accuracy with 50+ examples. Include all document variations: different vendors, layouts, scan qualities, and languages. Include 10–15% negative examples — documents that should NOT be classified as this type — to reduce false positives.

Can Syntex process documents that already exist in SharePoint?

Yes. When you publish a model to a document library, you can trigger processing of all existing documents in the library — not just new uploads. For large libraries (100,000+ documents), batch processing runs in the background over 24–72 hours depending on volume and model complexity.

Is Microsoft Syntex HIPAA-compliant?

Yes. All document processing occurs within the Microsoft 365 compliance boundary under your Business Associate Agreement. Sensitivity labels apply automatically to PHI documents. Audit logs capture every processing event. EPC Group has deployed HIPAA-compliant Syntex environments for healthcare clients with 100% audit pass rates.
