File.1 processes uploaded invoice documents. It does not provide an ERP ledger connection or imply support for supplier-invoice, payment or financial-report endpoints. Confirm your document workflow with us before building.
Offer file upload alongside accounting-system onboarding, so customers can share invoices using the route that works for them.
Use single approval to review and correct extracted data, or mass and automatic approval for the appropriate processing workflow.
After upload and processing, use the customer’s authorised consent to retrieve structured sales-invoice data.
