Sufio vs. Order Printer Pro: Shopify Invoicing Alternatives Compared

Both Sufio and Order Printer help Shopify merchants generate invoices and other necessary documents, but they take two very different approaches.

Order Printer Pro is an order printer app. Its main purpose is to generate documents directly from the latest order data in Shopify, typically only when requested.

Sufio, by contrast, is a professional invoicing app that’s fully integrated with Shopify. It stores invoices as independent financial documents and automates the full invoicing workflow, including follow-up documents like credit notes.

What is the difference between order printers and invoicing apps?

Both categories of apps help Shopify merchants create invoices, but they handle document updates, data integrity, and compliance in very different ways.

Order printer apps

Order printer apps generate invoices from the latest order data in your Shopify store. At first glance, this seems convenient, but it can quickly become a drawback because orders frequently change.

Customers may request partial refunds, or you might edit an order to add or remove items.

When this happens, the app regenerates the invoice to reflect the updated order. As a result, multiple versions of the same invoice can exist, meaning you and your customers may no longer be looking at the same document.

In many countries, invoices are expected to remain unchanged once they have been issued to customers, accountants, or tax authorities.

Having several versions of the same invoice can create both legal and accounting risks and may result in problems with your local tax authority.

The upside of order printer apps is cost. Because these apps rely entirely on Shopify’s order data and do not store separate invoice records, they are usually very affordable.

Invoicing apps

Invoicing apps like Sufio take a different approach by keeping invoices separate from the underlying order data in your Shopify store. This ensures that once an invoice is issued, it remains unchanged and retains its value as a valid financial document.

If an order is later modified, such as through a refund or item adjustment, the original invoice is left untouched. Instead, the app generates additional documents to capture the change.

For example, a credit note records refunded items, creating a clear and auditable trail without altering the original invoice.

Compared to order printer apps, invoicing solutions typically include features designed to meet legal requirements, such as sequential invoice numbering or support for e‑invoicing standards. This makes them a better fit for businesses that need to stay compliant.

These benefits come at a higher cost, reflecting the more robust systems involved.

Since invoicing apps store independent copies of financial documents, choosing a reliable and secure provider becomes increasingly important as your invoicing volume grows.

Feature comparison

Here's how Sufio and Order Printer Pro compare across the features that matter most to Shopify merchants.

Invoice automation

Sufio is built around a fully automated workflow. It creates and sends invoices based on specific triggers, such as when an order is paid or fulfilled. You can customize exactly when documents are generated and which types of orders they apply to.

It also automatically issues credit notes for returns and refunds, and sends reminders for overdue invoices.

In addition, Sufio supports fully configurable sequential invoice numbering. Invoices are assigned unique, consecutive numbers in the exact order they are created, whether they originate from orders or are created manually. This helps businesses meet strict legal and accounting requirements in many countries.

You can also customize the numbering format with prefixes, dates, or order references to match local regulations or internal standards.

Order Printer Pro approaches automation differently. It does not create or send documents on its own. Instead, it provides code snippets that can be added to Shopify’s notification emails, where documents are generated on demand when a link is clicked.

Documents are generated only on demand, either when a customer clicks a link in an email or when you manually trigger them from the app.

While this gives customers access to their invoices, it lacks the context-driven automation and reminder systems found in Sufio.

Order Printer Pro relies on Shopify order numbers for invoice numbering and does not offer an independent invoice sequence. Because invoices are generated only when requested and follow the order number rather than the creation order, the resulting numbers may not be consecutive. This can be an issue in regions that require strict, gap-free invoice numbering.

Credit notes

Credit notes are essential for handling returns and refunds while keeping accounting records accurate.

Sufio automatically generates credit notes whenever a refund or return is processed in Shopify. These documents are kept separate from the original invoice, preserving a clear and complete transaction history.

Sufio also supports multiple types of credit notes, including cancellation credit notes and incremental (partial) credit notes.

This flexibility makes it easier to handle full cancellations, partial refunds, and more complex return scenarios while remaining compliant with accounting and tax requirements.

Order Printer Pro can generate credit notes when refund data is present on the order, but documents are created on demand, either via the app or through links in Shopify emails.

It also lacks support for different credit note types and allows only one credit note per order.

B2B support

For merchants selling to other businesses, support for Shopify B2B features is often essential.

Sufio is officially recommended by Shopify due to its native integration with Shopify B2B.

Sufio automatically handles payment terms to set due dates, displays PO numbers, and can capture and validate VAT numbers from business customers. This ensures tax exemptions are applied correctly and that all required business details appear on the final document.

Order Printer Pro supports some B2B fields, such as payment terms and PO numbers, but these must be added manually via the code editor.

It does not offer native support for capturing or validating VAT numbers from B2B company locations, which may require complex manual workarounds.

International sales

Selling internationally requires support for multiple languages, currencies, and region-specific shipping documents.

Sufio supports 40 languages with professional translations. It can automatically detect the language used during checkout and generate the invoice in that language.

It also supports multi-currency billing and provides commercial invoices that include HS codes and country-of-origin values for international shipping.

Order Printer Pro supports 34 languages, but these are configured per template rather than automatically detected based on the customer’s locale.

It can also generate commercial invoices, though this requires adding custom code to the document templates.

E-invoicing support

E‑invoicing is becoming a legal requirement in many countries, particularly for B2B transactions. It ensures invoices follow standardized, machine‑readable formats that can be automatically validated and processed by tax authorities and business systems.

Sufio offers built‑in support for compliant e‑invoicing, helping merchants meet these legal obligations with minimal setup. It supports multiple country‑specific e‑invoicing standards, including ZUGFeRD in Germany, Factur‑X in France, and Peppol in Belgium.

In these countries, e‑invoicing is mandatory for B2B transactions. Sufio automatically generates invoices in the required format and submits them when applicable. This allows merchants to stay compliant with local regulations while continuing to use a familiar Shopify‑based workflow.

Order Printer Pro does not support e‑invoicing. Like other order printer apps, it cannot generate invoices in standardized e‑invoicing formats or submit them to national or international e‑invoicing networks.

As a result, merchants operating in countries where e‑invoicing is mandatory must rely on external tools or manual processes, increasing complexity and the risk of non‑compliance.

Design

The way your documents look is an extension of your brand identity.

Sufio offers a range of professionally designed Shopify invoice templates that can be customized using a simple visual editor.

Sufio also provides access to over 40,000 premium fonts from Monotype to ensure documents match your branding precisely.

For users who want full control, the app also includes a powerful template editor—letting you customize the document layout and design, and display any order, customer, or product property directly in your documents.

Order Printer Pro is primarily aimed at users who are comfortable working with code. It uses Shopify Liquid, which is familiar to many developers.

There is no visual editor beyond basic branding options like adding a logo or changing an accent color. This makes it a flexible tool for technical users, but a more challenging option for non‑technical merchants.

Integrations

Both apps offer integration with Shopify POS, allowing you to print or send invoices directly from physical retail locations.

Sufio integrates with the new Shopify customer accounts, as well as popular email marketing platforms like Klaviyo and Omnisend. This allows merchants to include invoice download links in both marketing and post‑purchase email flows.

Order Printer Pro offers more limited integrations, primarily focusing on Zapiet and Customer Accounts Hub. It does not provide a direct extension for the new Shopify customer accounts or native integrations with major email marketing platforms.

Pricing

Sufio offers tiered monthly plans starting at $7 for Starter (15 invoices), $19 for Growth (50 invoices), $49 for Professional (5,000 invoices), and $129 for Premium (unlimited).

All plans include a 14‑day free trial with no credit card required and prorated upgrades or downgrades.

Order Printer Pro is more affordable, with a generous free plan for up to 50 orders per month (all features, multiple documents per order). Paid plans start at $10 per month and go up to $40 per month. A 14‑day trial is also available.

Order Printer Pro appeals to budget‑conscious stores, while Sufio justifies its higher price with advanced automation and full legal compliance.

Summary and conclusion

Order Printer Pro is a reasonable fit if you need a lightweight, low‑cost way to generate invoices and packing slips and are comfortable working with a Liquid‑based template editor.

Its workflow focuses on on‑demand document creation and customer‑facing download links in Shopify’s existing emails, rather than a fully automated invoicing system.

Sufio is the stronger option when invoices need to function as independent, compliant financial documents.

It automates invoice and credit note handling, supports overdue reminders, includes built‑in e‑invoicing support, and is designed for B2B and international sales.

If your requirements are relatively simple and budget is the primary concern, Order Printer Pro may be sufficient.

For stores moving toward B2B, cross‑border sales, or stricter compliance requirements, Sufio is built to handle that added complexity.
