Extremely valuable app to ensure we can send compliant invoices to our clients. Fantastic support with a new feature implemented for us within 24hrs. Highly recommend the Simple Invoice product and team.

Very useful app that allows for a lot of customization - various document types, highly customizable templates and excellent customer service. We had some minor issues with translations/alternative languages and the customer service was really quick to reply and help us and they managed to fix the issue very fast. I highly recommend this app!

Very reactive customer service that helped me work around a limitation (from Shopify, not the app itself) with the billing address. Highly recommended app!

We’ve been using this app across our store and it’s been working exactly as expected. Clean setup, straightforward to use, and does what it says without unnecessary complexity. Support has also been responsive and helpful whenever we’ve had questions, which is always appreciated. Overall, a reliable app that integrates well with our workflow — happy to recommend it to other Shopify store owners.

We are very satisfied with Simple Invoice's service! Super fast, friendly, and easy to understand. We can wholeheartedly recommend them at any time. Thank you so much!

We've been using the application for a long time. The support has always been helpful. They've always listened to our problems and assisted!

this App is super easy to use, i love the designs and the customer service is brilliant. Super fast and helpful. 5 Stars thank you

First, I would like to offer my sincere apologies to the Simple Invoice team for the issues that occurred during this support experience. Here is the full sequence: I needed to obtain the website-specific hash ID, so I sent an inquiry email to the team. Because I did not receive a reply in time, I asked our partner app to forward the question to the team on my behalf. Unfortunately, I still received no response. After many attempts, I finally tried leaving a negative review, hoping it would attract attention. Although it was not an ideal method, it did directly connect me with a team member—a slightly amusing route. I hope the team can optimise the contact channels or open an in-app在线咨询 option and require every initiator to leave contact details, so inquiries can reach the right person accurately. Since I entered our company information in the store settings, that may be why I did not receive replies promptly. Despite the long time it took to reach the team, I found the service excellent. As soon as Robert understood my issue, he provided timely assistance, passed the relevant information to the technical support staff of our partner app, and worked with me to solve the problem. All follow-up responses were also very prompt, making the support experience outstanding! Once again, I apologise for this misunderstanding and express my gratitude to the team for their support and help.

Excellent support from customer service. I have been using Simple Invoice for the past four years, without any problems. They resolved my request within two days. The representative listens to my problem and understands. He provided me with a solution that I wanted exactly. Thank you, Simple Invoice, for excellent service. Phil India Stamps

The templates look professional, customization options are great, and it saves us tons of time every day. Customer support is quick and helpful whenever we need assistance. Highly recommended for any Shopify store looking to streamline invoicing!

Support has been excellent. They actually understand Shopify’s backend logic and gave me real answers when I asked about draft order behaviors not the generic canned responses I get from many invoicing apps.

Great app! I recommend installing it. Wide functionality, easy to configure, Fast and loyal technical support!

Professional looking invoices. Easy to use. I like that you can edit all the lines/fields and that it's built into Shopify. Much better than my old system.

Really, really simple to use, works straight away. Love that they have a free option for small businesses that you can then trade up onto with no sacrifices on great functionality. For me, it integrates directly with Australia Post, so it's been awesome to be able to get those labels sorted out straight out of Shopify without having to muck around. Really appreciate this app and the people who built it, it's great.

I highly recommend this app! The customer service is simply fast, responsive, and incredibly accommodating. Installation is simple, and using the app is just as easy. If you’re hesitating between this and another invoicing app, go with this one!

Had some issues with my invoices, the problem was quickly resolved. I alsop needed some custom input on my outgoing invoices and also this was quickly added to the invoice. Thank you very much :)

Easy to use and exceptional customer service, very helpful with making the changes required to suit our business. Highly recommended.

Excellent app and great customer service. We had a small problem occur. The team at Simplio responded quickly and provided a solution immediately. Highly recommend this app!

I am gonna make this as simple, as how Simple Invoice is just simply great. The App and more important, their support. Exceptional. If you need a better Invoicing solution that what Shopify provides out of the box, then don't think twice.

Excellent app and outstanding support! They customized our invoices exactly as we needed — highly recommended!
