Very useful app to generate Invoices and Reports for GST. It is great that the team is very quick & responsive and open to any feature tweaks.

Thank you for taking the time to leave us such a great review. Most people don't bother to leave reviews about positive experiences because they are unincentivized. It's only when we receive such positive feedback, do we rest knowing that we have done our jobs well. Thank you for giving us this proverbial pat on the back, you made our day!

This is a completely unfair review from the team at

We called them multiple times and also emailed them to explain how it works - but no response from them.

We have multiple options for setting HSN codes and hundreds of Shopify merchants are using the app without any issues.

We just wished that the team from laboratorydeal was a bit more understanding and not write this misguiding review.

After 7 days, we still have not got any response even after trying to reach them multiple times.

Perfect app. Exactly what I was looking for. Very simple to set up. Invoice templates are more than enough. Worth the price!

Simply put - does what it claims at the correct price.
Multiple feature request were added after suggestion so a very customer friendly approach.
Still needs some updates and changes such as fixing Credit Note Flow, adding option for FSSAI and IEC numbers on top of invoice.
These guys have the potential to OWN the Shopify GST invoicing in India


can we integrate this with busy software , as we are using that software for all our billings. Kindly guide on that.

We used this app to generate gst bills, reports for filing requirements. The team was prompt and helpful to assist with modifications/additions required in the reports to serve our purpose. Will continue to use this app given its cost effective and user friendly.

Sleek App is one of the best app for GST invoicing for as per Indian GST Laws. Easy to understand and use. Team at Sleek App is very supportive, provides prompt solutions for the issues faced. They also helped us to customize the details in the invoice as per our requirement.
