The portal at a glance

Invoiceflair is a web service for electronic invoices: validate, display legibly, convert between formats, create afresh, and derive from ordinary PDF invoices. Ten tools are available, eight of them without signing in. The same application runs as a public service and as an installation on your own premises.

Two deployment modes, the same tools

Mode	Address	What is different
Cloud	www.invoiceflair.com	public, free of charge, sign-in by magic link only
Enterprise	the host of your installation	on your own premises, no plan limits, password sign-in in addition

The tools are identical in both cases. Wherever something differs, this documentation says so explicitly.

The eight tools without signing in

Tool	What it does
Validate	check an e-invoice against EN 16931 or the rules of its national format
View	render invoice XML legibly for a human reader
Convert	transform between the formats, including from the ERP side
Create	build a compliant invoice from a form — optionally as a hybrid PDF
Extract	retrieve the embedded XML from a hybrid PDF
Combine	join your own PDF and your own XML into a hybrid PDF
PDF to e-invoice	read an ordinary PDF invoice, review it, release it
Invoice data capture	the same reading, but returned as structured JSON rather than an invoice

“Without signing in” is meant literally: no preview, no truncated result, no watermark.

The two tools that need an account

Tool	Why an account is required
Batch processing	many files in one run — this needs a queue and an assignment to a tenant
Bulk import	an ERP raw-data export turned into a batch of invoices — this needs a stored mapping profile

The account is free of charge and additionally unlocks the invoice archive, finalising with consecutive numbering, master data, your own Word templates, API keys and members. What depends on what is set out under Anonymous use or an account?.

The nine formats

Read and written: XRechnung, ZUGFeRD/Factur-X, Peppol BIS 3.0, FatturaPA (Italy), Finvoice (Finland), ebInterface and Austrofix (Austria), FA_VAT/KSeF (Poland) and Facturae (Spain). The engine also reads ERP raw data — SAP INVOIC IDoc, UN/EDIFACT, cXML, openTRANS, DATEV — and some twenty non-European document formats.

Reading and writing are not the same thing

Non-European mandatory formats are read but not written: their documents carry codes issued solely by the respective tax authority. Which formats belong to that group, and which are merely recognised without being readable, is set out under E-invoicing and its formats.
