E-invoicing reforms impose strict standards on corporate identification data. Often relegated to accounting, this requirement directly impacts your CRM structure.
To ensure compliance, customer data must be structured, validated, and synchronized in real time.
Why E-Invoicing Disrupts the CRM
E-invoicing requires the exchange of highly structured data containing precise legal information:
Mandatory identification data: Company registration numbers (such as SIRET or VAT numbers) and exact billing addresses. Any discrepancy leads to invoice rejection.
Real-time status tracking: The invoice lifecycle (submitted, rejected, paid) must sync back to the sales system to avoid payment follow-up errors.
Bidirectional linking: Each transaction must be unambiguously linked to a customer account or contract.
In a traditional CRM, this level of rigor requires complex forms, dozens of mandatory fields, and tedious manual entry that slows down sales teams.
The OSTRATA Approach: The AI-Piloted Headless CRM
OSTRATA eliminates regulatory compliance friction with a headless CRM architecture free of rigid forms. Your teams interact in natural language, while the AI manages data structure in the background.
Custom Data Schemas in Setup
In the Setup interface, you define your own custom objects and fields (e.g., Invoices, Tax ID, Transmission Status). Adapt your data model to legal requirements in seconds, without code. Database-level RLS isolation guarantees strict security.
Input and Updates via Operations (AI Chat)
Your teams do not need to fill out endless forms. In the Operations interface, a simple text message is enough:
"Link tax ID 123456789 to the Acme account and create a $1,200 invoice linked to the main Deal."
OSTRATA's AI interprets the request, executes the required tool calls, and updates your records instantly.
Open Synchronization via REST API
Connect your invoicing tool directly to OSTRATA using our REST API, secured by scoped keys. Payment statuses and tax identifiers update automatically without manual intervention.
Monitoring Compliance Daily
Manage the operational impact of e-invoicing through OSTRATA's other surfaces:
Live Views: Use AI-generated tables and dashboards to instantly flag customer accounts missing valid tax IDs before invoices are generated.
Gmail and Google Drive: Connect your personal and workspace accounts. Ask the AI in chat to analyze an invoice received via email or stored in Google Drive to extract metadata and update your database.
Telegram: Field teams can send receipts or tax details directly to the OSTRATA Telegram bot to link documents to the correct account instantly.
