invoicePress - EN16931 e-Invoice Viewer

invoicePress your visitors drop an electronic invoice onto your page and see it as a clear, structured view instantly — without any external service and without storing the file. A standalone WordPress plugin that reproduces the core function of the ZUGFeRD Quba viewer, right inside a simple shortcode. invoicePress you offer an e-invoice demo, a validation helper, or a customer-facing viewer, this plugin reads ZUGFeRD / Factur-X PDFs and CII / UBL / XRechnung XML files and renders every invoice field — optionally with the matching EN 16931 business-term numbers (BT-…). The result is displayed inline via AJAX, inside a Shadow DOM, so it looks identical in every theme. Key features Supported invoice formats ZUGFeRD / Factur-X (PDF) — the embedded XML is extracted and read automatically. CII (UN/CEFACT) XML — read directly. UBL / XRechnung (XML) — converted to CII internally and then read. Modern, Quba-inspired layout A single-scroll layout with coloured section tabs (filled = data present, light = empty section): a hero header with the highlighted amount due, followed by invoice data, buyer, seller, order/contract data, delivery information, payment, line items, VAT breakdown, totals, notes and attachments. All fields are always shown — even empty ones — exactly like the original viewer. EN 16931 business terms (BT numbers) Each field can be labelled with its EN 16931 business-term number. Visitors toggle the numbers live via a switch in the viewer, and you set the default per embed via the shortcode attribute bt=”1” / bt=”0” or globally in the settings. The field mapping was verified against the official EN 16931 specification. Theme independence via Shadow DOM The viewer is rendered inside a Shadow DOM with a full :host style reset and px units throughout, so no inheritable theme styles (font, size, colour, line-height) cross the boundary. The result looks identical in every WordPress theme. Security & privacy XXE protection (DOCTYPE rejection, no external entity loader, no network access while parsing), upload validation (extension + finfo MIME check + size limit), nonce-based CSRF protection with a live nonce against page caching, and a per-visitor daily upload rate limit. The file is processed in memory only and is never stored; every invoice value is escaped on output. Extensible template engine The data extraction is separated from the HTML rendering, so additional layouts can be added as a template subclass without touching the extraction logic. Why not pixel-perfect to Quba? The Quba viewer transforms with the KoSIT XRechnung XSLT 3.0 via Saxon-JS; PHP only supports XSLT 1.0. An own, Quba-inspired PHP template is used instead — functionally equivalent, but not the identical KoSIT markup.
