Billoxi: Shopify Smart Invoice PDF App Built by XLOXI

Billoxi is a Shopify smart invoice PDF application designed and developed by XLOXI PVT LTD for merchants who need professional order documents without retyping Shopify order details. The Challenge Many Shopify stores still create invoices and packing slips manually or with limited templates. That wastes time, introduces errors, and weakens brand presentation after checkout. Merchants needed a Shopify-native way to generate branded PDFs, automate documents for paid orders and refunds, and email customers using their own SMTP server. The Solution XLOXI built Billoxi as a full Shopify app with Admin API integration, a Polaris merchant dashboard, template customization, PDF generation, automation rules and bulk order tools. Line items, prices, discounts, taxes and totals stay synced with the original Shopify order. Key Capabilities - Create invoices, packing slips, credit notes, drafts and returns from Shopify orders - Customize logo, colours, fonts, language, numbering, tax details and layout - Print documents, download PDFs, or email customers via merchant SMTP - Automate invoices for paid orders and credit notes for refunds or cancellations - Bulk download, email and manage documents across multiple orders - Live preview and convert flows between document types Product Outcome Billoxi launched on the Shopify App Store at https://apps.shopify.com/billoxi with Starter, Premium and Ultimate plans (free trial available).
