Practical Details on Non-Matching of Invoice Numbers with Shipping Bills

1. Issue: Invoice Number Discrepancies between GST Returns and Shipping Bills

Background:

• Invoice numbers must be identical across all export-related documents to ensure smooth validation for IGST refunds.
• Exporters often face mismatches because of inconsistent numbering formats, manual entry errors, or use of different invoice sequences in the GST portal and customs declarations.

Common Causes of Discrepancies:

• Multiple Systems for Invoice Generation: Some companies use separate systems or software for generating GST invoices and shipping bills, leading to different numbering conventions.
• Manual Data Entry Errors: Manual entry of invoice numbers in the GST and customs portals increases the risk of typos, leading to mismatches.
• Internal Invoice Adjustments: Some businesses adjust or modify invoice numbers internally without updating this change on all documents, especially shipping bills.
• Non-Standardized Formats: Exporters may use different numbering formats or include additional characters (like prefixes) in one document but not in another.

Why This Issue Occurs:

• Lack of integration between the accounting/ERP system and customs filing systems, leading to manual intervention and errors.
• No defined standard for invoice numbering across departments or systems within the company.
• A low focus on regular reconciliation between export invoices and shipping bills before submitting documents for refunds.

2. Consequences: Mismatches and Halted Refund Processing

Impact on Refund Process:

• Customs and GSTN Dependency: Customs systems require exact matching of invoice numbers between shipping bills and GSTR-1 entries for refund approvals. Any discrepancy halts this validation, causing delays.
• Increased Manual Intervention: Authorities may flag the discrepancy, leading to time-consuming manual checks and additional documentation requests.
• Extended Refund Processing Times: Until exporters correct these mismatches, the refund processing is effectively frozen, impacting the cash flow and causing business disruptions.
• Heightened Scrutiny from Authorities: Repeated mismatches raise compliance concerns, potentially triggering deeper audits into other export-related filings.

Example Scenario:

• Case Study: An electronics exporter submitted invoices with unique codes in the GST portal but used a different sequence for shipping bills. The customs system could not match these invoices with shipping bills, resulting in delayed refunds for over six months until the numbering issue was identified and corrected.

3. Solution: Standardized Invoicing System and Data Verification

Steps to Eliminate Discrepancies between Invoice Numbers and Shipping Bills:

• Step 1: Standardize Invoice Numbering Across Systems
• Step 2: Implement Automated Data Checks
• Step 3: Conduct Regular Reconciliations
• Step 4: Institute Quality Control Measures for Manual Data Entry
• Step 5: Maintain an Error Log and Train Staff

Best Practices:

• Use Dedicated Export Invoice Formats: Create a unique format for export invoices, ensuring they are distinctly different from domestic invoices to avoid confusion.
• Lock Invoice Fields Post-Submission: Use software settings to lock invoice details, preventing accidental changes post-GST and customs submission.
• Integrate Software if Possible: Explore integrating accounting software with customs and GST portals to automate data sharing and reduce manual errors.

4. Benefits of Following These Solutions

• Smoother Refund Processing: Standardized and consistent data allows customs and GST systems to validate information seamlessly, ensuring faster refund approvals.
• Reduced Manual Corrections and Delays: Avoiding mismatches minimizes the need for correction requests or additional queries from authorities, speeding up the refund process.
• Better Cash Flow Management: Quick refund processing improves cash flow, allowing exporters to reinvest in their operations and reduce dependency on credit lines.
• Improved Compliance Reputation: Consistent, error-free filings enhance the business’s compliance profile, reducing the likelihood of audits or inquiries from tax authorities.
