ModulDeck is a German software vendor that develops WooCommerce plugins under the 'Pilot' product line. Its flagship product, RechnungsPilot, generates legally compliant e-invoices for WooCommerce stores, addressing Germany's phased e-invoicing mandate (2025-2028). It supports ZUGFeRD 2.0 (hybrid PDF+XML), XRechnung 3.0 (for public-sector billing), and GoBD-compliant archiving with SHA-256 hash values and audit trails, plus a Steuerberater (tax advisor) export that packages PDFs, XMLs, and audit protocols into a ZIP file. Core invoicing functionality is offered free, with a paid Pro License unlocking additional capabilities.
ModulDeck's companion plugin, DokumentenPilot, fills a gap in native WooCommerce document support by generating delivery notes (including partial delivery notes for split shipments), packing slips, credit notes, proforma invoices, and B2B quotations that can be converted to orders. Both plugins target WooCommerce 8.0+ stores on PHP 8.0+, are HPOS-compatible, and are designed to work together, sharing company data and design settings when both are installed. The products are distributed as GPL-licensed WordPress plugins with premium license tiers (documented shop pricing of EUR 49-399) sold directly through the ModulDeck website.
