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!

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
