CHALLENGE
Growing Scale, Rising Compliance Burden
As Udaan rapidly expanded, managing GST compliance for its ever-growing vendor base became increasingly complex. The legacy approach reliant on uploading GST certificates and manually verifying them was time-consuming, error-prone, and difficult to scale.
Delays in verifying GST registrations not only impacted vendor onboarding timelines but also introduced risks related to mismatched filings, input tax credit issues, and compliance bottlenecks.
SOLUTION
Simplifying GST Checks Through API Automation
To eliminate friction and improve accuracy, Udaan integrated Sandbox’s GST APIs directly into its vendor onboarding workflows. This allowed for real-time validation of GSTINs against official government records, automatically flagging discrepancies and reducing manual intervention.
By removing the dependency on document uploads and physical reviews, Udaan significantly reduced turnaround times and human error. The integration also enabled automated detection of invalid or inactive GST registrations, ensuring only compliant vendors transacted on the platform.
RESULTS
Faster Onboarding, Stronger Compliance
With automated GST checks, Udaan reduced vendor onboarding time by 2.5x, accelerating time-to-market for sellers and boosting operational efficiency. Manual efforts were cut by over 70%, allowing internal teams to focus on higher-value tasks.
The improved accuracy in GST data strengthened input tax credit alignment and reduced regulatory risks. By embedding compliance into its core processes, Udaan scaled confidently while maintaining trust and transparency across its growing B2B network.
