Samy: PDF Invoice Generator — Basic Automation for New Stores

Samy: PDF Invoice Generator offers foundational features for merchants looking to automate invoice creation and delivery for every order. The app includes:

• Automatic Invoice Generation: Invoices are created instantly for every order, helping merchants meet basic documentation requirements.
• Email Delivery (limits by plan): Automated email delivery of invoices, though volume is capped by plan tier (50, 500, or 10,000/month).
• Basic and Premium Customization: Merchants can adjust templates to a certain extent, with more options available on higher plans.
• Packing Slips & Return Forms: Generate packing slips and return forms, including barcodes for easier returns and inventory management.
• Custom Invoice Numbers: Ability to update and manage custom invoice numbers for organizational needs.
• Dedicated Customer Support (higher tiers): Customer support is included, with VIP priority on the Plus plan.

While Samy: PDF Invoice Generator covers the basics for merchants just starting out or handling low order volumes, it does not offer the advanced automation, B2B features, bulk actions, or breadth of integrations that Order Printer Pro: PDF Invoice provides. The absence of features like multi-language or multi-currency support, bulk export, or POS integration means it may not suffice for merchants with growing or complex operations.

Pricing and Value

Both apps offer a free plan for merchants with low order volumes, but the structure and value differ as you scale:

• Order Printer Pro: PDF Invoice has four pricing tiers. The Free plan covers up to 50 orders/month, including bulk print/export, draft orders, automation, and template customization. As order volume grows, the Starter ($10/month), Growth ($20/month), and Scale ($40/month) plans increase order limits from 500 up to 5,000+ monthly. All plans include the full suite of features, ensuring that even growing merchants access automation, customization, and integrations without additional module fees.
• Samy: PDF Invoice Generator also offers a free Basic plan (up to 50 invoices/month, basic customization, email delivery cap at 50/month). The Standard plan ($9.99/month) increases email delivery to 500/month, allows unlimited downloads, and unlocks premium customization and dedicated support. The Plus plan ($19.99/month) raises email delivery limits to 10,000/month and provides VIP support.

Order Printer Pro: PDF Invoice is designed for scale, offering predictable pricing as order volumes grow and advanced features at every tier. Samy is positioned for smaller stores or those with minimal documentation needs. Merchants looking for bulk operations, B2B features, and automation should note that these are included in all Order Printer Pro plans, while Samy’s feature set remains basic even as price increases.

Setup and Technical Fit

Technical compatibility and ease of integration are key considerations for any Shopify merchant adding new tools to their stack:

• Built for Shopify: Order Printer Pro: PDF Invoice carries the “Built for Shopify” designation, reflecting its deep integration and reliability with the Shopify ecosystem. Samy does not hold this designation.
• Integrations: Order Printer Pro: PDF Invoice integrates with Checkout, Customer Accounts, Shopify POS, Shopify Admin, Infinite Options, Order Printer, Order Printer Templates, OrderlyEmails, Point of Sale, and Store Pickup + Delivery. This broad compatibility means you can automate document handling across in-store, online, and pick-up channels. Samy, by contrast, integrates with Shopify Admin only.
• Language Coverage: Both apps currently support English.
• Bulk and Automation Features: Order Printer Pro’s bulk print/export, automated email delivery, and invoice automation make it well suited for merchants processing high volumes or looking to reduce manual effort. Samy lacks these bulk and advanced automation features.

For merchants with complex workflows, multiple sales channels, or a need for advanced automation, Order Printer Pro: PDF Invoice provides broader technical fit and more scalable operations.

Trust Signals

When choosing an app for a critical function like invoicing, reliability and proven performance are essential. Order Printer Pro: PDF Invoice has been available since 2014, with more than 2,600 reviews and a 4.9-star rating. This level of adoption and feedback reflects years of continuous use and improvement across a wide range of Shopify stores.

Samy: PDF Invoice Generator is new to the Shopify App Store (launched in 2025) and has only 2 reviews at the time of writing. While its 5-star rating is promising, the limited volume of feedback means there is less evidence of real-world performance or long-term reliability.

For merchants who want the confidence of widespread adoption and a proven track record, Order Printer Pro: PDF Invoice offers much stronger trust signals.

When Order Printer Pro: PDF Invoice Is the Right Choice

• You process more than 50 orders per month and need scalable, bulk documentation tools.
• You require advanced automation—automated PDF invoices, automated email delivery, and invoice automation.
• Your business model includes B2B sales, requiring VAT/tax support, e-invoicing standards, or custom invoice numbering.
• You use Shopify POS, Checkout, or other integrated tools and need a solution that fits seamlessly across all channels.
• You value 24/7 support and want proven reliability, backed by thousands of reviews and years in the market.
• You need customizable templates and document numbering for compliance or branding.

When Samy: PDF Invoice Generator Might Fit Better

• Your store is new or processes fewer than 50 orders per month and you want a free, basic solution for invoice automation.
• You require only basic customization and are comfortable without advanced features, integrations, or automation.
• You prioritize a lower cost for very small stores and do not need bulk actions or B2B capabilities.

Final Verdict

Order Printer Pro: PDF Invoice is the clear choice for Shopify merchants who need comprehensive, scalable, and reliable invoice automation. It offers a feature set unmatched by Samy: PDF Invoice Generator, including advanced automation, B2B support, bulk operations, and deep integrations—all backed by a decade of development and thousands of reviews.
