Overview<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Rubamin\u00a0Private Limited has been a market leader in Molybdenum and Zinc Chemicals for the past three decades. Located in Gujarat, India,\u00a0Rubamin\u00a0is a trusted name when it comes to manufacturing and supplying high-quality Molybdenum, Zinc, Tungsten, Vanadium,\u00a0Cobalt\u00a0and Nickel based chemicals; all manufactured under certified process controls for advanced applications.<\/span>\u00a0<\/span><\/p>

The Challenge<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

SAP Integration for E-Invoicing:<\/span><\/b>\u00a0Having used SAP as their primary ERP system from\u00a0inception,\u00a0Rubamin\u00a0required\u00a0a complete solution that could seamlessly integrate with SAP for e-invoicing purposes. It was essential that the integration process be smooth and free from operational disruption.<\/span>\u00a0<\/span><\/p>

IRN Generation Across Multiple Locations:\u00a0<\/span><\/b>One of the most significant challenges\u00a0Rubamin\u00a0faced was generating Invoice Reference Numbers (IRNs) across multiple plant locations\u00a0operating\u00a0under a single GSTIN. With teams spread across different sites,\u00a0maintaining\u00a0coordination, standardization,\u00a0and consistency proved increasingly difficult.\u00a0<\/span>\u00a0<\/span><\/p>

This highlighted a critical need for a centralized solution that could ensure uniform accessibility, standardization, and operational efficiency across all locations.<\/span>\u00a0<\/span><\/p>

E-Invoice vs. GSTR-1 Reconciliation:<\/span><\/b>\u00a0Invoice discrepancies were creating notable inefficiencies in\u00a0the company\u2019s\u00a0financial processes. To address this, they\u00a0sought a reliable reconciliation mechanism between e-Invoices and GSTR-1 filings, enabling\u00a0accurate\u00a0and\u00a0timely\u00a0reporting.<\/span>\u00a0<\/span><\/p>

Vendor and Customer GSTIN Validation:<\/span><\/b>\u00a0Given\u00a0the scale at which\u00a0Rubamin\u00a0engages with vendors and customers,\u00a0validating\u00a0each GSTIN on the GST portal before processing a purchase or sales order was a time-intensive and repetitive task. The volume of transactions made manual verification impractical and prone to delays.<\/span>\u00a0<\/span><\/p>

IMS Action on Multiple Invoices:<\/span><\/b>\u00a0Managing large volumes of invoices requiring simultaneous review and action placed considerable strain on\u00a0Rubamin’s\u00a0teams. Manual handling of this scale created bottlenecks, reduced process visibility, increased turnaround times, and made it difficult to\u00a0maintain\u00a0consistent compliance accuracy.<\/span>\u00a0<\/span><\/p>

GSTR-7\u00a0Return Filing:\u00a0<\/span><\/b>Filing\u00a0GSTR-7 returns through the GST portal, whether through manual data entry or the offline utility tool, is a detailed and time-consuming process. For a company of\u00a0Rubamin’s\u00a0scale, this demanded\u00a0significant time\u00a0and close attention to ensure accuracy and completeness.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

The Solution<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

In-House SAP Integration:<\/span><\/b>\u00a0With dedicated support from the\u00a0Sovos\u00a0India team,\u00a0Rubamin\u00a0successfully achieved a seamless SAP HANA integration. The direct collaboration between both teams\u00a0eliminated\u00a0the need for any third-party involvement, ensuring clear communication, faster resolution, and full ownership of the integration process from end to end.<\/span>\u00a0<\/span><\/p>

Cloud-Based E-Invoicing Software Solution:<\/span><\/b>\u00a0Following the introduction of e-Invoicing mandates in October 2020,\u00a0Sovos\u00a0India swiftly deployed its\u00a0E-Invoicing\u00a0Solution, enabling\u00a0Rubamin\u00a0to efficiently generate bulk Invoice Reference Numbers (IRNs) across all e-invoices.\u00a0<\/span>\u00a0<\/span><\/p>

The platform\u00a0consolidates\u00a0GST filing, e-way bill generation, and e-Invoicing functionalities into a single, unified system, streamlining operations for teams across multiple sites. Since adopting\u00a0Sovos\u00a0India\u2019s\u00a0solution,\u00a0Rubamin\u00a0has been able to generate bulk e-way bills with ease, ensuring\u00a0timely\u00a0deliveries without operational disruptions.<\/span>\u00a0<\/span><\/p>

E-Invoice and GSTR-1 Reconciliation:<\/span><\/b>\u00a0The\u00a0Sovos\u00a0India\u00a0Indirect Tax Compliance\u00a0Suite\u00a0includes a dedicated reconciliation feature that automatically\u00a0identifies\u00a0discrepancies between e-Invoices and GSTR-1 filings, enabling the team to take\u00a0timely\u00a0corrective action.\u00a0<\/span>\u00a0<\/span><\/p>

Rubamin’s team noted that the solution consistently delivers a match accuracy of approximately 99.99%, effectively\u00a0eliminating\u00a0the need for manual intervention.<\/span><\/b>\u00a0GSTR-1 filing has become both error-free and significantly more efficient, allowing the team to file with complete confidence in the accuracy of every submission.<\/span>\u00a0<\/span><\/p>

Vendor and Customer GSTIN Validation:<\/span><\/b>\u00a0Sovos\u00a0India provided an integrated GSTIN search solution that allows\u00a0Rubamin\u00a0to verify the compliance status of vendors and customers directly through their ERP system. This\u00a0eliminated\u00a0the need for manual portal lookups, reducing turnaround\u00a0time\u00a0and improving the reliability of pre-transaction validation.<\/span>\u00a0<\/span><\/p>

IMS Bulk Action:<\/span><\/b>\u00a0To address the challenge of managing large invoice volumes,\u00a0Sovos\u00a0India introduced a bulk action capability that allows\u00a0Rubamin’s\u00a0team to process multiple invoices simultaneously through a simple Excel upload. This significantly reduced manual effort and improved both process visibility and response times.<\/span>\u00a0<\/span><\/p>

GSTR-7 Return Filing:<\/span><\/b>\u00a0Sovos\u00a0India streamlined\u00a0Rubamin’s\u00a0GSTR-7 filing process by enabling direct data uploads in Excel format with the ability to save and\u00a0submit\u00a0to the GST portal. This approach has reduced manual errors, improved filing efficiency, and ensured\u00a0timely\u00a0and\u00a0accurate\u00a0tax submissions.<\/span>\u00a0<\/span><\/p>

Smooth and Simplified Return Filing:<\/span><\/b>\u00a0Through\u00a0Sovos\u00a0India’s GST filing software,\u00a0Rubamin\u00a0now\u00a0benefits\u00a0from bulk upload and download capabilities, along with PAN-GSTIN data retrieval, all within a single platform. The result has been a marked reduction in manual effort, fewer errors, and considerable time savings.\u00a0<\/span>\u00a0<\/span><\/p>

The complexities previously associated with manual filing, error identification, and reconciliation matching have been\u00a0largely eliminated, allowing the team to focus on higher-value tasks with greater confidence.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

Since partnering with Sovos India, Rubamin has experienced a significant transformation in its GST compliance operations. Key outcomes include:<\/span>\u00a0<\/span><\/p>

Near-Perfect Reconciliation Accuracy:<\/span><\/b>\u00a0The e-invoice and GSTR-1 reconciliation feature consistently delivers a match accuracy of approximately 99.99%. Manual intervention has been effectively eliminated, and the team now files with complete confidence in the correctness of every submission.<\/span>\u00a0<\/span><\/p>

Error-Free and Hassle-Free GSTR-1\u00a0Filing:<\/span><\/b>\u00a0GSTR-1 filing\u00a0has become a streamlined, reliable process. The effort previously spent\u00a0identifying\u00a0mismatches, correcting discrepancies, and manually reconciling data has been\u00a0largely eliminated, freeing the team to focus on higher-value activities.<\/span>\u00a0<\/span><\/p>

Operational Efficiency Across Multiple Locations:<\/span><\/b>\u00a0With a centralized platform managing e-Invoicing, e-way bills, and GST filing, teams across all plant locations now\u00a0operate\u00a0with uniform processes and consistent data, significantly reducing coordination challenges.<\/span>\u00a0<\/span><\/p>

Faster Vendor and Customer Onboarding:<\/span><\/b>\u00a0GSTIN validation, once a time-consuming manual task, is now handled directly through the ERP system. This has accelerated pre-transaction checks and reduced delays in processing purchase and sales orders.<\/span>\u00a0<\/span><\/p>

Significant Time and Effort Savings:<\/span><\/b>\u00a0Bulk upload and download capabilities, PAN-GSTIN data retrieval, and automated reconciliation have collectively reduced manual effort across the compliance function, resulting in considerable time savings and fewer human errors.<\/span>\u00a0<\/span><\/p>

Round-the-Clock Support:<\/span><\/b>\u00a0Rubamin’s\u00a0team has expressed strong satisfaction with\u00a0Sovos\u00a0India’s 24\/7 support, which has ensured continuity, quick resolution of queries, and sustained confidence in the platform’s reliability.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
