View Solutions review for Oxilayer PDF Invoice Generator

March 28, 2026

This is by far the best invoicing app on Shopify! I had downloaded and tried several other invoicing apps in the Shopify app marketplace before deciding on this one. You can create multiple templates (invoices, Proforma invoice) where as in other apps, you are limited to only one type of template. There are also templates like for orders, returns, refunds. From your Shopify Order page, you can send out the invoice with one click, under More Actions. You can also send it to another email address instead of the original customer. The best part is that it works with Shopify Flow. I love how every field on the invoice can be customized with the drag & drop editor. The app is very well designed and streamlined. Edwin from support is very responsive, and extremely helpful! I highly recommend this to all Shopify merchants who want to automate their invoicing process.
