PayDrop PDF Invoices, Shopify PDF Invoice Generator

PayDrop PDF Invoices is a Shopify PDF invoice generator. It automatically creates and sends branded invoices, credit notes, and packing slips triggered by your Shopify orders.

App Overview & Features

App Overview and Features

One system for every document your store sends
Built for merchants who need a Shopify PDF invoice generator that goes past a single template: multiple document types, custom metafield data pulled into the layout, and delivery through infrastructure you control instead of a shared mail server. Particularly useful for sellers of ebooks, PDFs, printables, and courses who need professional invoicing alongside their digital product delivery.

Shopify Invoice Dashboard & Document Tracking

See invoice revenue, documents generated, delivery success rate, and average invoice value without opening a single PDF. A generation trend chart and a Recent Invoices table with download, regenerate, and resend actions sit right on the dashboard.

Searchable Shopify Invoice History

Every invoice ever generated stays searchable in one place. Search by invoice number or order number, filter by template, and select multiple rows at once. The same download, regenerate, resend, and delete actions from the dashboard are here too, applied to the full history instead of just the last few.

Shopify Metafield Mapping for PDF Invoices

Map an order or product metafield to a placeholder alias, and it becomes a reusable variable like {{custom_alias_name}} inside any layout. Registration numbers, custom specs, or anything else living in a metafield can show up on the document without a developer touching the template.

Custom Invoice Numbering, Tax Details, and SMTP Delivery

Set an invoice prefix and starting sequence number, fill in your business name, address, and VAT or tax registration number once, and every document generated after that carries it automatically. Connect your own SMTP relay so delivery comes from your domain, not a shared one, and optionally back up every generated PDF straight to Google Drive.

No-Code and HTML, Liquid, and CSS Template Builder

Switch between a no-code visual builder and a full Developer HTML Editor for Liquid markup and CSS, with a live render on the right updating as you type. A documented set of shop, customer, order, address, and line-item variables sits alongside a genuine code editor for anyone who wants full control over the layout.

Manage Invoice, Credit Note, and Packing Slip Templates

Document Templates lists every layout by type and status, Create new template starts a fresh one, and Edit Layout, Activate, Deactivate, and Delete cover the rest. A store can run a Classic PDF Invoice, a Refund Credit Note, and a Standard Packing Slip side by side, active or held in reserve, without juggling separate apps.

Automated Document Triggers and Email Delivery

Each template gets its own automated trigger, such as Order Paid, along with its own email subject and body built from liquid variables like {{invoiceNum}}, {{orderNumber}}, and {{shopName}}. Once it is configured and SMTP is connected, the document generates and sends itself on every matching order, with no manual step in between.

Testimonials

We were spending far too much time creating invoices and making sure the right order details made it onto every document. PayDrop took that manual work out of our process and gave us a much cleaner way to manage everything from one place.

Marcus Hale

Northstar Goods

Our old invoices looked generic and didn’t include some of the custom information we needed for our customers. Being able to control the template and pull in our Shopify data made a big difference. It feels much more like part of our store now.

Rachel Bennett

Harbor & Pine

The biggest win for us was being able to automate the entire process without changing how our team handles orders. Once we set up the templates, triggers, and email delivery, the documents went out on their own. It saved our team a surprising amount of time every week.

Daniel Foster

Ridgeway Commerce

From an impact standpoint, we went from 0 to 1 to some degree. We had nothing when we first started and now we have a full product that we are proud to put in front of users and investors. We got new users and saw a 25% improvement over the days following the launch. Plus, the team also came 20% under budget which is huge!

Sam Rowen

Their team is the most amazing team I ever worked with! They have patience and help you with anything you need, making sure you understand and like your results. Definitely recommend it!

Felicia Robu

Customer support was fast and prompt – and even provided me with a screencast showing the plugin functionality I was querying.
