Picking the best Shopify invoice app depends on what you actually need: basic free documents, automated PDF delivery, tax-compliant B2B invoicing, or bulk printing at scale. Most stores start with Shopify's free Order Printer and outgrow it within a few months.
Your customer just got their package. Inside: a plain white packing slip with a Shopify order number and zero branding. It does the job, technically. But it also looks like it came from a dropshipper's garage.
Professional invoices and branded packing slips aren't just about looking polished. B2B customers often require proper tax invoices before they'll pay. EU regulations mandate specific invoice formats. And a branded packing slip with a discount code inside the box is one of the cheapest repeat-purchase tools you'll find. If you're still using Shopify's bare-minimum default documents, you're leaving money and credibility on the table.
Here are the best Shopify invoice and packing slip apps in 2026, compared on features, pricing, and what each one actually does well.
Shopify Order Printer (Free — Built Into Shopify)
Start here. Shopify's own Order Printer app is free, pre-installed, and handles the basics: invoices, packing slips, pick lists, and receipts. You can print documents for individual orders or bulk-print up to 50 at a time directly from your Shopify admin.
The default templates are functional but plain. If you want branded documents, you'll need to edit them using HTML, CSS, and Liquid — Shopify's templating language. That's fine if you're comfortable with code or have a developer. If not, you'll hit a wall fast.
Best for: New stores with low order volume that just need basic invoices and packing slips without paying anything.
- Price: Free
- Documents: Invoices, packing slips, pick lists, receipts
- Customization: Full control via HTML/CSS/Liquid (requires coding)
- Limitation: No PDF generation, no automated email delivery, no drag-and-drop editor
Order Printer Pro — The Most Popular Upgrade
Order Printer Pro is the most widely used invoice app on Shopify, with over 2,000 five-star reviews. It picks up where Shopify's free Order Printer leaves off: PDF generation, automated invoice emails, quotes for draft orders, and multi-currency support.
The app handles B2B invoicing, VAT breakdowns, and supports translations — making it a solid choice for international stores. You can filter and bulk-print documents from your admin, POS, or mobile, and the template editor doesn't require coding for basic customization.
Best for: Growing stores that need PDF invoices, automatic delivery, and multi-currency support without a steep learning curve.
- Price: Free (up to 50 orders/month), $10/month (500 orders), $20/month (5,000 orders), $40/month (unlimited)
- Rating: 5.0 stars (2,000+ reviews)
- Documents: PDF invoices, packing slips, receipts, quotes, refund/credit notes, returns forms
- Standout feature: Automated invoice delivery — invoices get emailed to customers without you lifting a finger
Sufio — Built for Tax Compliance and B2B
If you sell to businesses or ship internationally, Sufio is the app that takes invoicing seriously. It's officially recommended by Shopify for B2B stores, and its invoices are validated by certified accountants for compliance with EU, UK, and US tax legislation.
Sufio supports PEPPOL e-invoicing (required by a growing number of European governments), generates documents in over 40 languages, and lets you set up custom automation rules — like sending invoices only after payment, or routing copies to your accountant automatically. It also syncs with Shopify B2B payment terms and displays PO numbers on invoices.
Best for: B2B stores, EU merchants with legal invoicing requirements, and stores selling across multiple countries.
- Price: From $7/month (14-day free trial)
- Rating: 4.9 stars (411 reviews)
- Documents: Invoices, credit notes, receipts, payment reminders
- Standout feature: PEPPOL e-invoicing and accountant-validated tax compliance across 40+ languages
Orderly Print — Bulk Operations at Scale
Orderly Print is built for stores that process hundreds of orders daily and need to print documents fast. You can tag, filter, and bulk-print up to 500 orders at once — invoices, packing slips, pick lists, and shipping labels in a single batch.
Merchants praise it for streamlining fulfillment during peak periods. The app also exports orders to Excel, which is useful for accounting reconciliation. Customization options are solid, though the template editor isn't as polished as some competitors.
Best for: High-volume stores that need to process hundreds of documents at once during peak seasons.
- Price: Free plan available, paid plans for higher volume
- Rating: 4.8 stars (68 reviews)
- Documents: Invoices, packing slips, pick lists, labels
- Standout feature: Bulk-print 500 orders at once with tag-based filtering and Excel export
F: PDF Invoice Generator — Strong Free Tier for Small Stores
F: PDF Invoice Generator (by Flavor) offers one of the better free plans in this category: 60 PDF prints and downloads per month, with 10 built-in invoice layouts. It automatically generates PDF invoices when orders come in and emails them to customers.
The app supports all languages and handles packing slips, refund notes, and credit notes alongside standard invoices. If you're a small store doing under 60 orders per month and want professional-looking PDFs without paying a subscription, this is worth trying first.
Best for: Small stores under 60 orders/month that want PDF invoices on a free plan.
- Price: Free (60 PDFs/month), paid plans for higher volume
- Documents: PDF invoices, packing slips, refund notes, credit notes
- Standout feature: 10 pre-built invoice layouts that work without any customization
Printout Designer — Drag-and-Drop for Non-Coders
If you want full control over your document design but don't know HTML, Printout Designer is the answer. It uses a drag-and-drop template builder where you can position logos, text fields, barcodes, and product images exactly where you want them.
The app also automates printing and emailing tasks, and merchants report up to 5x faster order processing after setting up their workflows. With a 4.9-star rating across 78 reviews, it's a smaller app that punches above its weight.
Best for: Stores that want fully custom document designs without touching any code.
- Price: From $4.99/month (free trial available)
- Rating: 4.9 stars (78 reviews)
- Documents: Invoices, packing slips, labels, custom documents
- Standout feature: Drag-and-drop template builder with barcode and image support
Order Printer Templates — One-Time Purchase, No Subscription
Order Printer Templates takes a different approach: instead of a monthly subscription, you pay a one-time fee of $29 per template. Each additional template is 50% off. The templates work directly with Shopify's free Order Printer app, so you get professional designs without needing a separate app running in the background.
No coding required. You pick a template, customize it with your branding, and it works inside the Order Printer you already have. For stores that just need better-looking packing slips and invoices without ongoing costs, this is the most economical option.
Best for: Budget-conscious stores that want professional templates without a monthly fee.
- Price: $29 one-time per template (50% off additional templates)
- Documents: Invoices, packing slips, receipts, returns forms, gift receipts
- Standout feature: One-time purchase model — no recurring charges
PrintHero — Vendor-Specific Packing Slips
PrintHero solves a problem most invoice apps ignore: creating separate packing slips per vendor/supplier. If you work with multiple suppliers and need to send each one a packing slip that only includes their products from a multi-vendor order, PrintHero handles it automatically.
You can also add coupon codes directly onto packing slips — turning every shipment into a repeat-purchase opportunity. Batch printing is included for processing multiple orders at once.
Best for: Multi-vendor stores that need supplier-specific packing slips and in-box marketing.
- Price: $14.99/month (7-day free trial)
- Rating: 5.0 stars (5 reviews)
- Documents: Invoices, vendor-specific packing slips
- Standout feature: Packing slips split by supplier with built-in coupon code placement
Which Shopify Invoice App Should You Pick?
Skip the comparison paralysis. Here's the decision tree:
- Zero budget, low volume: Start with Shopify's free Order Printer. If the default templates look too plain, add an Order Printer Template for a one-time $29.
- Growing store, need PDFs and automation: Order Printer Pro. The free tier covers 50 orders/month, and $10/month gets you 500 — most mid-size stores won't outgrow the Growth plan.
- B2B or EU compliance: Sufio. Nothing else matches its tax compliance depth, PEPPOL support, and accountant-validated documents.
- High volume, peak season spikes: Orderly Print. Bulk-printing 500 orders at once is a real time-saver during Black Friday or flash sales.
- Want drag-and-drop design: Printout Designer. Full visual control at $4.99/month.
- Multi-vendor fulfillment: PrintHero. Vendor-specific packing slips aren't common — if you need them, this is your app.
Install one, set up your templates, and print a test invoice before your next batch of orders goes out. If you're switching to a 3PL, get your invoice templates sorted first — they'll need documents that match your branding. A branded packing slip costs nothing extra per shipment, and it's the one piece of marketing your customer is guaranteed to see — because it's already in their hands.
