Excellent app and great support. Does everything you need for invoicing and perfect for companies that use the native bundling app on shopify to fix the invoices.

— AutoChimp Electronics

Oxilayer Invoice ist für unseren Shopify-Shop eine ausgezeichnete Rechnungs-App und erfüllt genau den Zweck, den wir gesucht haben. Besonders hervorheben möchte ich jedoch den Support. Ich habe in den letzten Wochen mit vielen Shopify-App-Anbietern Kontakt gehabt, aber der Support von Edwin war mit großem Abstand der schnellste und beste, den ich bisher erlebt habe. Auf Verbesserungsvorschläge w...

Like the app and the support team

— Rare Parfum

What's not to love - Really easy to set up and use - Customer service is supper responsive - a ton of features - the ability to customize templates and at half the price of the previous app we were using. Very happy we made the switch.

— AGMProducts

— Bella Contact Lenses

Excellent app — the best we’ve tested so far Oxilayer Invoice is simply the best invoicing app we have tested to date. It is clear, efficient, easy to use, and perfectly meets our daily needs. The customer support is also outstanding: fast, professional, and very effective. Every question is answered clearly, with a genuine willingness to help. We highly recommend this app to any Shopify store...

— My Roller Stone

it is a bit misleading to claim 'forever free' 'unlimited free invoices' when once installed it says that we need to pay for exceeding the monthly limit of 50 orders. I prefer this to be explicit before installing as there are other apps to compare with similar plans.

EXCELLENT APP!

— WTC Comics

The app has everything I need and more, and the integration with my store is seamless. But what really stands out is the support team: they are truly amazing. So far, this is the best support I’ve experienced among Shopify apps. Great work!

— SidecarTridge

Très bonne app et support efficace. Le systeme de modèles est flexible, on peut faire un rendu tel qu'on l'imagine pour notre marque !

— Stooly

After using various other (expensive!) invoice apps, finally found an app that works well with Shopify Flow. Setup is straight forward and app works reliable. Thanks to great support by Edwin, we now also use the app to send our customers documents needed to clear US Customs.

— Rotaris

Great support from Edwin! Fast, reliable and considerate. The app handles all our use cases. 100% would recommend.

— Brownie

Great app and excellent support. Edwin has been very helpful, responsive and always friendly throughout the setup process. Highly recommended!

— Printoria

By far the best invoicing app I have ever used on the Shopify App Store, and I have been using Shopify for four years now. The app is simply outstanding. It automates a huge number of tasks, including sending invoices, certificates, and other documents as PDF attachments. This is a major advantage because it allows you to maintain full control over the information sent to customers and ensures th...
