Quicko is an authorized GSP (GST Suvidha Provider) under the GSTN framework. As a GSP, we provide secure, scalable, and developer-first access to the GST ecosystem — helping businesses, SaaS platforms, and enterprise systems integrate directly with GSTN, without the burden of managing backend complexity, security protocols, or compliance requirements.

Whether you're building a tax-tech product, automating filings for clients, or embedding GST features into your ERP — Quicko GSP gives you everything you need to go live, stay compliant, and scale confidently.

One Gateway for the Entire GST Stack

Quicko GSP offers a single, unified API layer to access the full spectrum of GST compliance services — from return filing to e-Invoicing and E-Way Bills.

Here's what you can do:

File GST Returns

Seamlessly integrate APIs for return preparation and filing, including:

• GSTR-1: Report outward supplies

• GSTR-3B: Summarise liabilities and input tax credit

• GSTR-2B: Access auto-drafted input tax credit reports

These APIs are synchronized with the latest formats, validations, and rules issued by GSTN.

Quicko GSP lets you integrate E-Way Bill operations into your workflows, with APIs to:

• Generate new E-Way Bills

• Extend validity

• Cancel or update details

All API requests are processed in real time and comply with NIC guidelines.
