We've had a great experience with this app. It has made our GST compliance simple and hassle-free, and the bulk product management features have saved us a lot of time. The support team has been prompt, knowledgeable, and always willing to help whenever we've had questions. Highly recommended for anyone looking for a reliable GST invoicing solution for their Shopify store.

Great app for gst invoicing, reduces headache of hiring more staff, improves accuracy and speed of invoicing

5-Star for good communication from the team. The app is working well, but I have a few suggestions for improvement. I would also like to see if the email notification for individual orders is reflected on the order page.

Really good support and best app for Indian businesses

— FiorraLifestyle

We tried all the apps listed on the Shopify store related to GST invoices, and after thorough testing and trials, Sleek GST Invoices turned out to be the best fit for our requirements. Their customer support is also very responsive. We highly recommend the Sleek GST Invoice application for Shopify stores.

waste of money

Every month when you download/export monthly report, it shows incorrect number of order. You have to mail them every month to fix it. It never syncs all orders. If you're paying for the app you at least expect it to work with basic functions. (been using it from a year now, so you can understand the frustration). Look for the alternative apps. Because they are not fixing it at all.

Freaking Amazing NGL Our backend had an issue their support team not only helped us fix that ut also made sure that we are able to continuously use their software as per the settings of different add ons present in our shopify account.

Excellent App. There was some issues with their team where they were not able to give support initially but they resolved all my issues and have even been hands on with developing features Indian sellers need. Cannot recommend them enough.
