mathlabkit review for Sleek GST Invoices ‑ India

Aug. 15, 2020

Sleek App is one of the best invoicing app we have used so far for our Shopify stores. The team at Sleek is very prompt, responsive, flexible and super helpful. We required specific customisations on the GST Invoices and it was perfectly done by the team. We are a Digital Marketing Agency working for various clients and we look forward to use this app for all our upcoming e-commerce projects. We definitely recommend Sleek App for everyone who requires a clean, neat GST Invoices and awesome reliable customer service experience. Thank You Sleek Team.
