Mega PDF Invoices

Mega PDF Invoices focuses on automating PDF invoice creation, receipts, and order printing for Shopify merchants. Its core capabilities include generating and exporting invoices in bulk, automated PDF invoice delivery (on Premium and above), customizable templates, and support for draft orders. Higher pricing tiers unlock advanced features such as unlimited invoices, credit notes, custom QR/barcodes, VAT number collection, Peppol integration, and custom email sending via SMTP. The app supports both B2B and B2C invoicing at its highest tier, with options for custom features and recommended suitability for Shopify Plus stores.

While Mega PDF Invoices covers many important bases, it does not offer exclusive features that Order Printer Pro: PDF Invoice does not. Its feature set is solid for merchants with straightforward needs, but lacks the advanced automation, compliance, and integration capabilities that enable larger or more complex stores to operate at scale without friction.

Pricing and Value

Both apps offer a free plan, but their structures differ significantly in terms of scalability and included features. Order Printer Pro: PDF Invoice’s free tier covers up to 50 orders per month, offering bulk print/export, customizable templates, automation, and metafield support. As your business grows, the Starter ($10/month), Growth ($20/month), and Scale ($40/month) plans offer increased monthly order limits—up to unlimited orders—while retaining all core features across every tier. This makes it easy for merchants to scale smoothly, only paying more as their order volume grows.

Mega PDF Invoices also starts with a free plan for up to 50 invoices per month. Its Premium plan ($9.99/month) unlocks unlimited invoices, automated delivery, credit notes, and watermark removal. The Enterprise tier ($49.99/month) adds Peppol integration, custom template services, and advanced exporting and emailing options. The Ultimate plan ($99.99/month) targets large-scale merchants or Shopify Plus users with wholesale invoicing and multi-country VAT handling.

Order Printer Pro: PDF Invoice’s tiered approach means every merchant—from startup to enterprise—gets access to a consistent core feature set, with pricing scaling in line with order volume. In contrast, some advanced features in Mega PDF Invoices only become available at much higher price points, which could be prohibitive for growing stores with tighter budgets.

Setup and Technical Fit

Both Order Printer Pro: PDF Invoice and Mega PDF Invoices are Built for Shopify apps, ensuring they meet Shopify's standards for integration, reliability, and performance. Each app supports English, and both provide bulk print/export and draft order support. However, Order Printer Pro: PDF Invoice delivers more out of the box for merchants with diverse technical needs:

• POS Integration: Manage and print invoices for both online and in-person sales from a single platform.
• Multi-currency and Multi-Language Support: Serve international customers with invoices tailored to their locale and currency, helping avoid confusion and improving customer experience.
• Automated Email Delivery & Invoice Automation: Reduce manual work and streamline communication with customers automatically, no matter your order volume.

Setup is straightforward for both apps, but Order Printer Pro: PDF Invoice’s comprehensive automation and integration features minimize ongoing management for busy merchants. Its deep Shopify integration allows you to maintain consistent workflows as your business expands.

Trust Signals

Order Printer Pro: PDF Invoice has been serving Shopify merchants since 2014 and has amassed 2,619 reviews—a powerful testament to its reliability and effectiveness across a wide range of store sizes and industries. Its long time on the market and extensive user base offer merchants confidence that the app is stable and well-supported. Mega PDF Invoices, in contrast, was launched in 2019 and has a much smaller base of 55 reviews. While its rating is strong, the limited review volume may be a consideration for merchants seeking proven solutions with broad adoption and a longer history of performance.

Final Verdict

For most Shopify merchants, Order Printer Pro: PDF Invoice delivers the most comprehensive, scalable, and trusted solution for managing invoices, packing slips, and order documentation. Its unmatched review volume, extensive automation features, and flexible pricing make it a natural fit for businesses at any stage of growth. The app’s long track record proves its reliability, while advanced capabilities—like B2B management, POS integration, and multi-currency/language support—ensure it adapts as your needs evolve.
