The best Shopify invoice apps turn each order into a branded PDF invoice and packing slip and email it to the customer automatically when the order comes in. Choose on three things: how the plan is metered, how you edit the template, and which extra documents you need, such as credit notes, quotes or e-invoice formats.
Do you need one at all? If you sell a few orders a week to shoppers who never ask for an invoice, Shopify's order confirmation email may be all the paperwork you need. The moment business buyers ask for a PDF with their details on it, you start refunding orders and need a matching credit note, or your packing slips look nothing like your brand, an app starts paying for itself in saved admin.
This page is about order documents for a store: invoices, packing slips, credit notes and quotes. What has to appear on an invoice in your country is set by your own tax rules, so check them, with your accountant if you have one, before you rely on any template.
What you'll pay, and what gets counted
Entry paid plans for invoice apps run from about $6 to $15 a month on their Shopify listings right now, one app lists itself as free, and the bigger tiers for busy stores cost noticeably more. Volume decides where you land, and the apps don't count it the same way.
Some meter orders per month; others count invoices per month. That difference bites if you also send credit notes and packing slips, so check whether those use up an invoice allowance. Then size the plan on your busiest month, not your average. A store that does a third of its orders in November needs a different plan from one that sells steadily all year, even if their yearly totals match.

Four questions that narrow the nine down
- How many orders a month, roughly? Plans are usually metered by volume, either orders per month or invoices per month. Know your busiest month, not your average one.
- Who edits the template? If it's you, look for a visual drag-and-drop editor. If a developer looks after your theme, HTML and Liquid code gives them full control.
- Which documents beyond the invoice? Packing slips, credit notes for refunds, quotes for draft orders, return forms and proforma invoices all turn up on these listings. Write down the ones you'd use this month.
- Do you sell to businesses? If so, look at B2B features and whether you need an e-invoice format, which four of the nine apps on this list mention.
With those four answers in hand, most of the list above falls away on its own, and you'll probably be choosing between two or three.

Drag and drop, or hand it to a developer
I'd start almost everyone on a visual editor. It lets you drag in your logo, move the address block and change colours without touching code, so you're not waiting on anyone to fix a typo in your footer. HTML and Liquid, the template language Shopify themes use, lets you do things a visual editor can't, such as showing a line only when an order has a certain tag, or printing a customs note only on international orders.
Two apps here offer both, with support staff who'll help with custom code. That's the safest middle ground: start visual, and hand the template to a developer only when you hit a limit.
Whichever you pick, print a test invoice for your messiest order before you switch automatic sending on. Use one with a discount code, a refunded line, shipping to a different address from billing, and a product with a long variant name. If any of that breaks the layout, you'd rather find out now than from a customer.

B2B paperwork and e-invoices
If you sell to other businesses, the invoice becomes something your buyer's accounts team has to process, not just a receipt. Look for quotes you can convert, proforma invoices for buyers who pay before dispatch, and payment reminders for buyers on terms.
E-invoice formats are starting to show up on listings too. One app on this list embeds ZUGFeRD or Factur-X XML inside the PDF, two European e-invoice formats, and another lists sending through the PEPPOL network on a higher plan. Whether you need any of that depends on where you and your buyers are and on your own tax rules, so treat these as features to ask your accountant about, not boxes to tick because they're there.
Make the invoice send itself
If someone on your team still has to remember to send invoices, the app is only half doing its job. Several apps send the document automatically when an order arrives. Others add a download link to Shopify's own emails, the customer account page or the thank-you page, so buyers can fetch an invoice months later without emailing you.
I'd switch on both if your app allows it. Automatic sending covers the buyer who wants it today; the account link saves you the request in March from someone doing their year-end. If you'd like a refresher on where those order details live first, my guide to Shopify orders walks through it.
My pick by store type
A small retail store: pick an app with a free plan, a visual editor and automatic sending. Brand the invoice and packing slip, test it, and you're finished in an afternoon.
A busy store that ships every day: bulk printing matters more than template polish. Choose an app that prints invoices and packing slips for a whole batch of orders at once. If labels are the bigger job, Shopify shipping apps cover that side, and some shipping tools print packing slips with the labels. ShipStation vs Shippo compares two of the common choices.
A wholesale or B2B store: go for quotes, proforma invoices, credit notes and payment reminders in one app, and ask your accountant whether you need an e-invoice format before you pay for a plan that includes one.
A store with a developer: choose an app with HTML and Liquid editing, so your documents can follow the same logic as your theme.
