GST Pro: GST Invoice India

The App is quite good - after the recent GST change, setup in Shopify and our payment provider was turning out be a problem for textiles in the same HSN but different GST rates for different price bands. Aiswarya from GST Pro was very helpful, followed up, set up an online call immediately, coordinated with the technical and resolved the issue during the call.
The support and interaction superb and I would rate it 5-star. The only reason for 4-star is that the interface of the app can be better as well changes to the templates more user and visual friendly.
All-in-all, very useful.
