What you can build

Full access to Finwaise's document processing engine through RESTful endpoints.

Document Upload

Upload invoices, receipts and scanned documents (PDF, JPG, PNG) through presigned upload URLs, one file or up to 50 per request.

AI-Powered Extraction

Automatic data extraction with AI: amounts, dates, vendor info, line items, and tax details.

Real-time Webhooks

Get notified when a document finishes processing and when an electronic invoice is authorized or rejected. No polling needed.

Structured Export

Retrieve processed data in JSON format. Export to Excel, CSV, or push directly to your ERP system.

Electronic Invoicing

Create sales drafts and issue them through the tax authority (ARCA in Argentina): preview, confirm, follow the CAE and download the PDF. Sandbox first, idempotent by design.

Multi-Tenant Ready

Full tenant isolation per company. Manage multiple entities from a single API integration.
